  • 4. Lesson: 1 INTRODUCTION OF COST ACCOUNTINGCost Accountancy “It is the application of costing and cost accounting principle, method and techniques to thescience, art and practice of cost control and the ascertainment of profitability. It includes thepresentation of information derived there from for the purpose of managerial decision – making”. The term ‘Cost Accountancy’ includes Costing and Cost accounting. Its purposes are Cost-control and Profitability – ascertainment. It serves as an essential tool of the management for decision –making.Cost Accounting “The process of accounting for cost from the point at which expenditure is incurred orcommitted to the establishment of its ultimate relationship with cost centres and cost units. In its widestusage it embraces the preparation of statistical data, the application of cost control methods and theascertainment of the profitability of activities carried out or planned” Cost accounting means suchas analysis of accounting and other information as to enable management to know the cost involved ineach activity together with its significant constituent elements in order to arrive at proper decisions.Costaccounting provides management with cost data relating to products, processes, jobs and differentoperations in order to control the costs and maximize the earnings. It play a vital role in all the businessactivities.Definition of Cost Accounting The application of costing and cost accounting principles, methods and techniques to thescience, art and practice of cost control and the ascertainment of profitability. It includes thepresentation of information derived these from for the purpose of managerial decision making.Objects of Cost Accounting 1. To serve as a guide to price fixing of products. 2. To disclose sources to wastage in various operations of manufacture. 3. To reveal sources of economy in production process. 4. To provide for an effective system of stores and material. 5. To measure the degree of efficiency of the various departments or units of production. 6. To provide suitable means and information to the top management to control and guide the operations of the business organisation. 7. To exercise effective control on the costs, time and efforts of labour, machines and other factors of production. 8. To compare actual costs with the standard costs and analyse the causes of variation. 9. To provide necessary information to develop cost standards and to introduce the system of budgetary control. 10. It enables the management to know where to economize on costs, how to fix prices, how to maximize profit and so on. BSPATIL 4
  • 5. TECHNIQUES AND METHOD OF COSTING The types and techniques of costing are as follows: 1. Historial Costing: ‘The ascertainment of costs after they have been incurred’ Historical costs are, therefore, ‘postmortem’costs as under this method all the expenses incurred on the production are first incurred and them the costs areascertained. 2. Standard Costing: ‘The preparation and use of standard costs, their comparison with actual costs and the analysis of variance to their causes and points of incidence’. Here the standards are first set and then they are compared with actual performances. The differencebetween the standard and the actual is known as the variance. The variances are analyzed to find out their causesand also the points or locations at which they occur. 3. Marginal Costing: ‘The ascertainment of marginal costs and of the effects on profit of changes in volumes or type of output by differentiating between fixed costs and variable costs’. The fixed costs are those which do not change but remain the same, with the increase or decrease in thequantum of production. The variables costs are those which do change proportionately with the change inquantum of production. The marginal costing takes into account only the variable costs to find out ‘marginal costs’. Thedifference between Sales and Marginal costs is known as ‘Contribution’ and contribution is an aggregate ofFixed costs and Profit/Loss. So the fixed costs are deducted from the contribution to find out the profits.Marginal costing is a technique to ascertain the effect on profits. Marginal costing is a technique to ascertain theeffect on profit by the change in the volume of output or by the change in the type of output. 4. Direct Costing: The practice of charging all direct cost to operations, process or products, leaving all the indirect costs to be written off against profits in the period in which they arise 5. Absorption Costing ‘The practice of charging all costs, both variables and fixed, to operations, processes or products. This is the traditional technique as opposed to Marginal or Direct costing techniques. Here both the fixed and variables cost are charged in the same manner.Methods of Costing The methods of costing can be divided into three main groups: 1. Job Costing; 2. Process Costing; and 3. Farm Costing. 1. Job Costing: The job costing methods are applicable where the unit of manufacture is one and BSPATIL 5
  • 6. complete in itself. They include printers, job foundries, tool manufactures, contractors, etc. the following methods are included in Job Costing: (i) Contract Costing: This method if applied in undertakings erecting buildings or carrying out constructional works, e.g., House buildings, ship building, Civil Engineering contracts. Here the cost unit is one and completed in itself. The cost unit is a contract which may continue for over more than a year. It is also known as the Terminal Costing, since the works are to be completed within a specified period as per terms of contract or agreement executed by the contractor and contractee. Contracts can be differentiated from fobs in as much as the contracts jobs are carried out outside the factory and generally are of a long-term while jobs are carried out inside the factory and are of a short duration. If an order complete in itself and meant only for the person who has placed the order, this job-order is executed inside the press and the completion of the order takes a short time as against the contract which may take years. (ii) Batch Costing: In this method, a batch of similar or identical products is treated as a job. Here the unit of cost is a batch of group of products, costs are collected and analyzed according to batch numbers and the costs are ascertained batch wise. This method is applied in pharmaceutical industries where medicines or injections are manufactures batch wise or in general engineering factories producing components in convenient batches. 1. Process Costing: Process costing method is applicable to those industries manufacturing an number of units of output requiring processing. Here an article has to undergo two or more processes for reaching the stage of finished goods and succeeding process till completion.Classification of Cost The cost-classification is the process of grouping costs according to their characteristics. The cost canbe classified into the following: 1. According to elements; 2. According to Functions or Operations; 3. According to Nature or Behaviour, 4. Accounting to Controllability, 5. According to Normality, 6. According to Relevance to decision-making and Control. • According to Elements: The cost is classified into i) Direct Cost, and ii) Indirect Cost according to elements, viz., Materials, Labour and Expenses, the description of which occurs in the earlier pages of this chapter. • According to Functions: the cost is classified into the following: i) Production Cost or Manufacturing Cost, ii) Administration Cost, iii) Selling Cost, and iv) Distribution Cost, BSPATIL 6
  • 7. A brief description of each these items are given below: i) Production Cost is ‘The cost of sequence of operation which begins with supplying materials, labour and services and ends with primary packing of the product’. It is also known as Manufacturing of Factory Cost. ii) Administration Cost is “The Cost of formulating the policy, directing the organisation and controlling the operations of an undertaking, which is not related directly to a production, selling, distribution, research or development activity or function.” Administration Cost comprise office and Administration expenses. iii) Selling Cost is “The cost of seeking to create and stimulate demand (sometimes termed ‘marketing’) and of securing order.” It is also known as Selling expenses or Selling overheads which include all the expenses of Selling Department. iv) Distribution Cost is “The cost of sequence of operations which begins with making the packed product available for dispatch and ends with making the re-conditioned returned empty package, if any, available for re-use”. It is known as Distribution expenses or overheads which include expenses like packing, warehouse expenses, cost of freight, shipping charges and also the expenses of re-conditioning the returning empty packages for using them again. • According to Nature or Behaviour: Cost can be classified into i) Fixed Cost ii) Variable Cost, and iii) Semi-Fixed for Semi-variable Cost. i) Fixed Cost is “A cost which tends to be unaffected by variations in volume of output. Fixed costs depend mainly on the effluxion of time and do not vary directly with volume of rate of output. Fixed Costs are sometimes referred to as period costs in systems of direct costing.” Fixed costs or Fixed expenses are those expenses which do not change with the increase or decrease in the quantum of production but remain stable. They are period costs, e.g., Rent of Building, Salaries etc. ii) Variable Cost is “A cost which tends to vary directly with volume of output, Variable costs are sometimes referred to as direct costs in systems of direct costing.” Variable costs or expenses are those which increase in direct proportion with the increase in production or which decrease in direct proportion with the decrease in production, e.g., Direct Materials, Direct Labour, Power, Fuel etc. iii) Semi-fixed or Semi-variable cost is “A cost which is partly variable.” This is a cost with changes but not in direct proportion to the increase or decrease in the production-output, e.g., Repairs and Maintenance, Salary of supervisors etc. • According to controllability: The cost can be divided into: i) Controllable Cost, ii) Uncontrollable Cost. i) Controllable Cost: This is a cost which can be influenced by the action of a specified member of an undertaking. The organisation is divided into departments or responsibility centres each managed by a Head. The costs of a particular department or centre re guided by the person-in-charge of the department. The costs which can be controlled by a ‘specified member’ who is generally an important link in the management are the controllable costs. they Head of a cost-centre or a department ahs control over variable costs only which include Prime cost and other variable overheads. So the controllable costs are the variable costs. v) Uncontrollable Costs: it is a cost which cannot be influenced by the action of a specified BSPATIL 7
  • 8. member of an undertaking. Uncontrollable costs are generally the Fixed costs, the control of which does nto lie within the province of a member of the undertaking. The change in Fixed costs is a mater to be decided at the top level of the management depending upon the policy of the undertaking. Another example of he uncomtrollable cost is where the cost of one department is shared by the other department for reason that the other department is taking the benefit of services of the department. Suppose, the cost of Power departments is shared by the Machine Department, the cost of this share is uncontrollable as it has no control over the cost of the other department, viz., the Power Department. • According to Normality: The cost is classified into i) Normal cost, and ii) Abnormal cost i) Normal Cost: It is the cost at a given level of output in the condition at which that level of output is normally attained. ii) Abnormal cost: it is a cost which is beyond normal cost. • According to relevance to decision-making and Control:The costs classified on this basis are the following i) Shut-down Cost: A cost which will still be required to be incurred even though a plant is closed or shut-down for a temporary period, e.g., the cost of rent, rates, depreciation, maintenance etc., is known as shut-down cost. ii) Shun Cost: A cost which has been incurred in the past or sunk in the past and is not relevant to the particular decision-making is a sunk cost. If it is decided to replace the existing plant; the written down book value of the plant less the sale value of the existing plant, is a Sunk a Irrevocable cost. iii) Opportunity Cost: “The net selling price, rental value or transfer value which could be obtained at a point in time if a particular asset or group of assets were to be sold, hired, or put to some alternative use available to the owner at that time” is the opportunity cost. The cost which are related to the sacrifice made or the benefits foregone are opportunity costs. to take an example, if a part of the factory building has been let out on rent and now we want to use that portion for installing a plant, we would naturally lose the rent that we used to get. So the loss of rent is the opportunity which would arise due to putting the part of that factory building to an alternative use available to the owner, and this cost should be kept in view while installing the plant. iv) Imputed cost: it is hypothetical cost required to be considered to make costs comparable. If the owner of the factory charges rent of the factory to the cost of production to make cost comparable with that of those undertakings which run production in rented factories, it is an Imputed cost as the rent has actually not been paid. Some is the case with charging Interest on one’s own capital.COST-CENTRE AND COST-UNITCost are ascertained according to Cost Centres or Cost Units.Cost-centreA Cost-Centre is a very wide term and includes the Productions. Department Processes, Work orders, ServiceDepartment, Operations, Machine Centers, Area or regions of sales, Warehouses, Persons, etc., of which thecost is to be ascertained.A Cost-Centre can be classified into the following four types: 1. Impersonal, 2. Personal, 3. Operation, 4. Process.For manufacturing operations, the cost centres may be Production cost centers, i.e., the Production Departmentsengaged in producing, or the Service cost-centres, i.e., the Service Departments which help the production work BSPATIL 8
  • 9. e.g., Store, Power Dept. Internal Transport Dept., Repairs and Maintenance Dept., etc.,For sales operations, the cost-centres, all the machine or the persons operating those machines are broughttogether under one cost-centre for determination and control of costs. where the work is carried on throughprocesses, each process is a cost centre. A machine or a group of machines can also be cost-centre. The CostCentres are very useful for analysis, ascertainment and control of costs.Cost UnitA Cost Unit is a unit of quality of product, service, or time (or a combination of these) in relation to which costsmay be ascertained or expressed.Job is a cost unit which consists of a single order (or contract).Batch is a cost unit which consists of a group of identical items which maintains its identity throughout one ormore stages of production.Product Group is a cost unit which consists of a group of similar products.Thus, cost unit is a sub-division into proper nomenclatures attributable to a unit of measurements of cost. CostUnits are of two types: 1) Single. 2) Composite. The examples of Single Cost unit are-per tone, per meter, perkilogram etc., and the examples of composite units are-per passenger-kilometer, per tone-kilometer etc.INSTALLATION OF COSTING SYSTEMThe need and importance of the installation and the organisation of a good system of cost accounting are beingincreasingly realized presently all over the business versatility. The common experience of enthusiastic youthsclimbing the business – tree and falling mid-way without even collecting the leaves owes to the ignorance of heuse installation and organisatoin of accosting system, and to the infatuation that the profits could be earnedwithout it. A good system is the key-point governing, the mechanism of an enterprise in the field of costcontrol, ascertainment of profitability, and managerial decision-making.Installation of a cost system is not an expense but an investment as the rewards are much greater than theexpenses incurred. The cost system is for the business and not the business for a system of cost. Therefore, thesystem has to be so designed as to meet the specific needs of the enterprise. A) General Consideration for installing Costing SystemThe general considerations to be observed in installing a costing system are as follows: • The Objective: Whether the objective of installing the costing system is limited to a specific area, e.g. material management, or fixing selling price. Or to arrive at a certain managerial decision; or the object is to install the system for covering all the aspects of cost affecting the business. The approach to install the system will be dependent on its objectives. • The Area of Operation: Having decided the objective, the areas of operation of the system are to be studied, by which the management can be best benefited. If production is slack, attention will have to be paid to increase it; if production is good but the sales are receding, study will be made to increase the sales and action taken according to the results of study and analysis. Such areas which require immediate attention are to be carved out on priority basis to be handled by the cost system, • The Organisation of the Business: No system of cost installation would succeed until the organisation structure of the business is taken into account. The organizational part would help to determine the scope of working and improvement. If the interests of management call for certain minor changes in the organizational structure, to its advantage, the same may have to be done. • The Conception & Reception of the Idea: The idea of the installation of the cost system is to be placed before the staff and the workers in a manner that it is well received and not objected to on flimsy BSPATIL 9
  • 10. grounds. The success of the system would depend on the cooperation of he persons engaged in the enterprise, and the cooperation will be forth coming only if the idea and plans are well conceived and received. The benefits of introducing the system to all the sections should be well explained. • Collection of Data & Prompt Information: The cost data works as a base for decision-making. There should be evolved a proper system for the collection of the required cost data and information promptly. Secondly, there should be a system to verify the correctness of the data supplied, otherwise the conclusions drawn would be wrong and time spent in its working would go waste. • Cost Records & Cost Books: The maintenance of cost records and cost books depends on the size and nature of the business, but the basic requirements. The manner in which the financial accounts could be interlocked into an integral accounting system has to be studied and worked out. Decision has to be taken if two separate set of books-one for financial accounts and other for cost accounts-have to be maintained and thereafter the results are to be reconcile. Proper books and records are to be kept and maintained to meet the requirements of either of the two situations mentioned above. • Control system for the Elements of Cost: System would have to be devised for recording and controlling costs of materials, labour and overheads, in accordance with costing principles and procedures. • Type and Method of Costing: The choice of method of costing would depend on the nature of production, e.g., Job Cost method or the Process Cost method. For cost control, standard costing along with Budgetary control may have to be selected and applied. Similarly, for decision making, Marginal and Differential costing techniques may be found useful. Preparations for the application of the particular method and technique/type should be made initially. • Responsibility Accounting: Responsibility accounting is a technique of cost control by delegating, etc., known as responsibility centres. Its has to be judged whether a particular official who had been assigned a particular function, has implemented the same or not within the time’ allotted to him, or not, and thus the responsibility has got to be fixed for failure-action on individual persons, for the sake of control of cost. For this purpose, a system of responsibility accounting should be evolved. B) Specific considerations for installing costing systemThe specific considerations as distinct from general considerations to be kept in view while installing a costsystem are as follows: • Size and Nature of Business: In a business of big size, a detailed cost system is necessary while in a small business, the system should be within the requirements so that the expenses on the installation and its working may not out-weigh the utility. • The cost system is good for business engaged in manufacturing or in service-rendering concerns but for others. Even in production enterprise like colliery where the production costs are all direct costs, the financial where the production costs are all direct costs, the financial accounts may be so designed as to obviate the need of any cost system, unless otherwise called for. • Products: the nature of product determines the method of costing to be applied. If the material content of the product is more valuable, the material cost records need be kept in comparatively more elaborate manner so as to make material cost control effective. Same is the position with regard to labour and overhead. • Organisatoin: The organizational set up for a costing system should be modeled that the control part is exercised by the Cost Accountant, as such, the present organizational set up of the costing department need close study to suggest necessary changes. • Functional study: The functional divisions of an undertaking based on cost are a) Manufacturing, b) Administration, and c) Selling & Distribution. A study of the present working of the different BSPATIL 10
  • 11. departments in necessary to suggest improvements. C) Principles for Smooth WorkingThe following principles should be kept in mind while introducing the cost system: • The system should be simple and easy to operate. • The system should be flexible, so that it may be expanded or contracted per needs of the business. • The existing pattern should be disturbed only as little as may be considered desirable. • The desired changes be introduced gradually and not in haste. • Confidence be created by the Cost accountant in the minds of management and • Executives regarding the utility of the system, so as to avoid unnecessary criticism • And to obviate obstacles. D) Line of ActionThe following line of action is recommended for the installation of cost system. • Determination of the type of costing and the method of costing, as may be suitable for the undertaking. • To prepare forms, card, report-performs, books etc., for keeping records of all the elements of cost, viz., material, labour and overheads. • To decide issues regarding material cost control, i.e., purchase, storing, issue and valuation. • To decide matters regarding labor cost control, i.e., job evaluation, merit rating, appointment, time recording, division of work, remuneration of labour and other allied problems like idle time, overtime, labour turnover, casual workings, etc. • Where the work is carried on more by machines, proper records be kept for the machines. • To suggest a suitable system for the collection, classification and analysis of all. • Types of everheads, i.e., manufacturing, administrative, and selling & distributive. • To decide the methods of allocation and apportionment of overheads among the production departments and Service departments which should be earlier clearly demarcated, and to decide the method of absorption of overheads. • To decide normal capacity of production and prepare budgets and standards. • To maintain books of cost control based on double-entry principle. • To devise information system by which the costing department may communicate to other departments and receive reports and other necessary informations promptly .Merit of Cost AccountingHelpful in Planning and Decision Making: Cost information brings to light the profitable activities of the BSPATIL 11
  • 12. organisation. It provided the sound and rational basis for planning, the changes in products, plants, processesand techniques of production. The information provided by cost accounting is also useful in evaluating thevarious alternatives involved in a situation before taking any final decision.Inventory Control: As an efficient stores accounting system is essential to an adequate system of cost accounts,in effective check is provided on all materials and stores.Ascertainment of Costs: Cost accounting is very helpful in calculating the cost of an article being produced bythe enterprise. It helps in fixing the selling price of the product.Standard Costs: It helps the production manger not only to find what various jobs and processes have cost butalso what they should have cost. The pre-planned standard costs are used for comparison of the cost of theproducts.Assistance in Manufacturing: Cost accounting pinpoints lapses in purchases of raw materials and otherarticles, their utilization. It indicates where wastages are occurring long before the production is finished. Ithelps to take immediate steps to avoid such losses and wastes.Promotion of Sales: Cost accounting is also very helpful in the promotion of sales by adopting an appropriateprice policy. The technique of break even analysis serves as constant remember to increase the sales to the breakeven point. It also seeks to control the selling and distribution coasts.Evaluation of Profitability: It helps in elimination unprofitable activities and operations.Profit can be Maximised: Cost accounting helps the management in maximizing profits by eliminating allwastes and uneconomical processes. This cost accounts help in increasing points and minimizing loses.COST SHEETCost Sheets are statements setting out the costs of a product giving details of all the costs. Presentation ofcosting information depends upon the method of costing. A cost sheet can be prepared weekly, monthly,quarterly or annually.In a cost sheet besides total expenditure incurred, cost per unit of output in case of each element of cost can beshown in a separate column. The cost sheet should give cost per unit in the previous period for the purposes ofcomparison.Advantages of Cost Sheet 1. It is a simple and useful medium of communication which gives information about costs to all levels of management in a simple and lucid form. 2. It helps in comparative study of the various elements of costs with the past results and standard cost. Thus it helps the management in control process. 3. It helps the management in fixing up the selling price more accurately. 4. If acts as a guide to the manufacturer and helps him in formulating a definite and profitable production policy. 5. It enables a producer keep a close watch and control over the cost of production. 6. It shows the total cost and the per unit of the units produced during the given period.Problem 1The following particulars have been extracted from the costing records of a manufacturing co., for the year BSPATIL 12

  • 18. Lesson 2 Material Cost The term ‘materials’ refers to such commodities which are supplied to the manufacturing industry in their crudeor original forms. They are raw in nature of have to be processed further. Broadly, these may be classified in thefollowing groups: Raw materials, components, consumable stores, Maintenance Materials, Tools etc. Since the underlying purpose of cost accounting is to minimize the cost of production, it is important that aneffective control is exercised over them. The storage space and storage costs re reduce thereby. Control over materials isalso necessary to prevent extra-expenses on their unnecessary purchase and improper use. A regular supply of materialsgreatly helps the production schedule. It is necessary, therefore, that statements are prepared to accurately record thevalue of materials consumed by each department of job. Material Cost Control envisages a proper organisatoin for the efficient purchasing and storing of the materials,and for making them issued to the departments or the cost-centres in appropriate quantities. At the proper times andvalued at the right prices. The materials cost control aims at keeping the material cost within reasonable limits, budgets or standards. This control is exercised beginnings from the point the orders are prepared for being placed with the suppliers,and ending at the point the materials are effectively utilized in production or are disposed off otherwise. The following factors contribute to purchase control: i) Determination of Quantity to be purchased Quantities purchased in excessive number or weight block the working capital and the quantities purchased below the reasonable limit endanger the continuous working of the factory. ii) Determination of the Ordering Point The ordering point of the ordering level is one at which the order for purchase of materials is to be placed with the suppliers when the stock of that material is reduced to that point by consumption or otherwise. iii) Determination of Price at which to be purchased The selection of right suppliers and the best terms available out of the quotations received helps this factor.The Purchase cycle constitutes the following: 1. Initiating the purchase; 2. Receiving of the Purchase Requisitions; 3. Deciding important factors relating to purchase; 4. Selecting the suppliers; 5. Placing purchase-orders and follow-up 6. Receiving the supply and returning unwarranted suppliers; 7. Inspecting the material received; and 8. Passing invoices for payment.The important factors to be decided are: a) What to purchase; b) When to purchase; and c) How much to purchase. After receiving the Purchase Requisitions, the next step is to select the suppliers to whom the orders may be sent forthe supply. This is done by inviting tenders or quotations from different suppliers. While inviting the tenders, the supplying firms should be requested to state their terms and conditions of supply,delivery time, mode of payment, etc., clearly and to send the tenders in sealed covers. Having accepted the tenders, the orders are place by the Purchase Department with the firms selected fro thepurchase of requisitioned materials. The purchaser order should be prepared on the printed form and should contain all the necessary details, so as to BSPATIL 18
  • 19. leave no room for any ambiguity or doubt and so as to avoid legal complications. Follow-up of the Purchase order if essential to keep the schedule of supply by the specified date so thatproduction work may not suffer. The Receiving Department checks the supply from the copy of the Purchaser order and prepares his report of thegoods received. The Inspection Department makes an inspection of the goods received regarding the quality and specifications.Stores Records 1. Bin Card A Bin card, also known as Bin Tag or Stock card, is a card showing quantitative record of the receipts, issues and closing balances of the material kept in the corresponding bin. The Bin card is placed in the bin or shelf or is hung over the almirah or the rack otherwise known as ‘Bin’. Separate Bin cards are prepared for each item of stores and if two different materials are kept in one almirah, two Bin cards, one for each, are prepared, treating the almirah as two bins. 2. Stores Ledger Stores Ledger is a record of stores, both in quantity and value and is maintained by the stores Accountant. It is similar to Bin card but with the main difference that value of material is shown in the Stores ledger. Stores Ledger is an important book and the account of each item of stores is maintained separately. While Bin cards are maintained by store-keeper in the store, Store Ledger is maintained in the accounting department by the Stores Accountant. Material Control and its Requirements “ ‘Material Control’ may be defined as the regulation of the procedures for requisitioning, buying, receiving, storing, handling and usage of materials”. The main requirements of a system of material control are: • Planning and fixation of definite responsibility for each function of material. • Co-ordination between departments responsible for requisitioning, purchasing, receiving, inspecting, storing and utilizing the materials, • Centralization on purchases. • Use of material purchase budget and material requirement budget. • Use of standard and uniform forms, and • Proper system of stock control.For proper application of the material control the following steps are necessary. 1. Purchasing of materials 2. Receiving and inspecting of materials 3. Storing of materials 4. Pricing material Issues 5. Accounting materials losses. 6. Keeping physical and perpetual inventoryPurchasing of Materials In a large manufacturing concern, a separate purchase department is set up with the object of effecting all purchases. The top management lays down the purchase department. It is the function of the purchaser department to decide: i) What to purchaser; ii) When to purchase; iii) form where to purchase; iv) how much to purchase, and v) finally at what price the material should be purchased.

  • 20. Maintenance of Stock Levels The next important point after determination of EOQ is to decide as to when the order for purchase should beplaced. The answer is simple. The order for purchase should be placed when the stock is reduced by usage to the OrderPoint. The Order Point is one where the order should be placed for the economic order quantity. For deciding OrderPoint, two things, viz., (1) Lead time and (2) Usage during Lead time, are the determining factors. Lead time is thesupply time, or to be more specific, Lead Time is “the time interval between placing an order and having materials onthe factory floor ready for production…” Usage means the sue of materials by consumptions for productions, or the stock of finished goods sold. Sometimes purchase are made in large bulk in a season if the goods are seasonal, i.e., available in one seasononly, or at a time when it is feared that the goods may not be found available in the near future due to some reason. Special items for which no limit or order-points are fixed may be purchased as and when needed. To avoid over-stocking and under stocking each items of the inventory has the Maximum Level. MinimumLevel and an Order point.Order Point It is also known; ‘Ordering Level’; or ‘ Recorder Point’, or ‘Reordering Level or ‘Ordering Limit’, it has been stated earlier that Order Point is at which order for supply of materials or goods is placed. To decide the Order Point, three factors are considered, viz., (1) Lead time (2) Usage during Lead time, and (3) Minimum Limit, or the Safety stock. In order to ensure that the optimum quantity of material is purchased and stocked, neither less nor more, the storekeeper applies scientific techniques of materials management. Fixing of certain levels for each items of materials is one of such techniques. The following levels are generally fixed. 1. Maximum level 2. Minimum level 3. Order level 4. Danger level 1. Maximum level The maximum stock level indicates the maximum quantity of an item of material which can be held in stock at any time. The maximum stock can be calculated by applying the following formula. Maximum level – Re-order level + re-order quantity – (minimum consumption X minimum re-order period) 2. Minimum level Minimum level represents the quantity below which the inventory of any items should not allowed to fall; in other words, an enterprise must maintain minimum quantity of stock so that the production is not hampered due to non- availability of materials. If some buffer inventory is acting as a cushion against reasonable expected maximum usage. Formula: Minimum level = Re-order level – (Normal consumption x normal re-order period) 3. Re-ordering Level Point Re-ordering stock level in relation to an items of stock is the point at which it becomes essential to initiate purchase orders for its fresh supplies. Normally, re-ordering level is a point between the maximum and the minimum levels. Fresh orders must be placed before the actual stocks touch the minimum level. Reorder level = maximum re-order period x maximum usage. 4. Danger level The danger level is below the minimum level and represents a stage where immediate steps are taken for getting BSPATIL 20
  • 21. stock replenished. When the stock reaches danger level it is indicative that if no emergency steps are taken to restock the material, the stores will be completely exhausted and normal production stopped. Generally the danger level of stock is fixed above the minimum level but below the re-ordering level.Economic Order Quantity AnalysisEconomic Order Quantity This represents the normal quantity to be placed on order when the stock has reached its re-order level. Re-ordering quantity is to be fixed taking into account the maximum and minimum stock levels. The quantity ordered mustbe that which, when added to the minimum stock, will not exceed the maximum stock to be carried at any point of time.The following factors govern the re-ordering quantity. 1. Average consumption 2. Cost of pacing order 3. Cost of storage 4. Interest on capital etc.,Carrying cost of inventory consists of i) The costs of physical storage, such as cost of space, handling and upkeep expenses, insurance, cost of obsolescence etc. ii) Interest on capital invested (the opportunity cost of the capital blocked up) and iii) Cost of placing the order each time.Economic order quantity or economic lot size (if it relates to production) refers to the number ordered in a singlepurchase or number of units should be manufactured in a single run so that the total costs-ordering or set up costs andinventory carrying costs are at the minimum level. In other words, it is the quantity that should be ordered at one time soas to minimize the total of i) Cost of placing orders and receiving the goods, and ii) Cost of storing the goods as well as interest on the capital invested. The economic order quantity can be determined by the following simple formula.EOQ = Economic order quantity or number of units in one lot.A = Annual usage in unitsS = Ordering costs for one order (or set-up costs for one set-up)I = Inventory carrying costs per unit per year.This formula is based in three assumptions: i) Price will remain constant throughout the year and quantity discount is not involved. ii) Pattern of consumption, variable ordering costs per order and variable inventory carrying charge per unit per annum will remain the same throughout, and iii) EOQ will be delivered each time the stock balance, excluding safety stock, is just reduced to nil.Problem 1 Suppose the annual consumption is 675 units, 10% is the interest and cost of storing an article costing Rs. 30 perunit, cost of placing and order is Rs. 18.

  • 23. The term ‘Inventory’ is used to denote (i) goods awaiting sale (the stock items of a trading concern and thefinished stocks of a manufacturer); (ii) the goods in course of manufacture, known as work-in-progress, and (iii) goodsto be used directly or indirectly in production, i.e., raw materials and supplies. In a manufacturing company, normally the cost of materials constitutes fifty percent of the production cost andthe cost of inventory (i.e., raw materials W.I.P., and finished good) represents about one-third of the total assets. As thecosts of materials and inventory are quite formidable but at the same time controllable, there is a great need felt forproper planning, purchasing, handling and accounting for the same, and also to organize the system of inventory controlin a manner that it may provide the maximum profitably to the management.Objectives of Inventory Control The objectives of inventory control as listed below: 1. To exercise proper control on the purchases and issues of inventories; proper storing; elimination of wastage; and regulating the proper supplies to works and to customers; 2. Pricing of the inventories on suitable basis; 3. Proper recording, and scientific inventory management 4. To have proper assessment of income through the process of matching appropriate costs against revenues. 5. To maintain inventory of sufficient size for the operations to go on uninterruptedly but the size should match with the optimum financial involvement.Techniques of Inventory ControlThe techniques or the tools generally used to effect control over the inventory are the following: 1. Budgetary techniques for inventory planning; 2. A-B-C. System of inventory control; 3. Economic Order Quantity (E.O.Q.) i.e., how much to purchase at one time economically; 4. Maintenance of Stock levels to decide when to purchase; 5. Perpetual inventory system and the system of store verification; 6. Reduction of surplus stocks and review of slow-moving or stagnant items. 7. Control Ratios.Budgetary Techniques For the purchase of raw materials and stocks, what we required is a purchase Budged to be prepared in terms ofquantities and values involved. The sales stipulated as per sales Budget of the corresponding period generally works outto be the key factor to decide the production quantum during the budget period, which ultimately decides the purchasesto be made and the inventories to be planned.A-B-C Analysis To exercise proper control on stores, it is essential that the store items should be classified according to valuesso that the most valuable items may be paid greater and due a attention regarding their safety and care, as compared toothers. The stores are divided into three categories generally, viz., A, B, and C. In the ABC system, greatest care and control is to be exercised on the items of ‘A’ list as any loss or breakage orwastage of any items of this list may prove to be very costly; proper care need be exercised on ‘B’ list items andcomparatively less control is needed for ‘C’ list items. The rules relating to receipt maintenance issue and writing offstores items should be formed in accordance with the utility and value of the items based on the above categorization. Manufacturing organizations find it useful to divide materials into three categories for the purpose of exercisingselecting control on materials. An analysis of the material cost will show that a smaller percentage of items mayrepresent a smaller percentage of the value of items the percentage number of which is more or less equal to their valueof consumption. Items falling in the first category are treated as ‘A’ items, of the second category and ‘B’ items anditems of the third category are taken as ‘C’ items. Such an analysis of materials is known as ABC analysis. Thistechnique of stock control is also known as stock control according to value method or always Better Control method orProportional parts value. Analysis method. Thus, under this technique of material control, materials are listed in ‘A’, ‘B’and ‘C’ categories in descending order based on money value of consumption.ABC analysis measures the cost significance of each item of materials. It concentrated on important items, so it is also BSPATIL 23
  • 24. known as ‘Control by importance and Exception’.Advantages: 1) A Strict Control is exercised on the items which represent a high percentage of the material costs. 2) Investment in inventory is reduced to the minimum possible level. 3) Storage cost is reduced as a reasonable quantity of materials, which account for high percentage of value of consumption will be maintained in the stores.VED Analysis: VED – Vital, Essential, Desirable – analysis is used primarily for control of spare parts. The spare, parts can bedivided into three categories – vital, essential or desirable – keeping in view the critically to production.Perpectual Inventory System Perpectual Inventory is a system of records maintained by the controlling department, which reflects thephysical movement of stocks and their current balance. It aims at devising the system of records by which the receiptsand issues of stores may be recorded immediately at the time of each transaction and the balance may be brought out soas to show the up-to-date position.The records used for perpectual inventory are: (1) Bin Cards; (2) Store Ledger Accounts or Stores Record cards; (3) The forms and documents used for receipt, issue and transfer of materials.Advantages of Perpectual Inventory system 1. It keeps the record of stocks upto date. 2. The materials are kept within the Minimum and Maximum Limits. Non-observance of the limits fixed is detected. 3. The materials going out of stock are easily detected and purchased at the appropriate time to avoid the risk of closing down. 4. It acts as a moral check on the staff of the stores Department and so the possibilities of loss or theft of materials are minimized. 5. The recording of stocks in Bin cards as well as Store Record cards minimizes the error in entering the receipts and issues of stocks. 6. The discrepancies noted after physical counting are detected and corrective action is taken promptly to avoid future occurrence. 7. The materials getting state or being wasted are detected and placed in right atmosphere. 8. The prompt balancing of closing stocks enables quick preparation of final accounts. 9. The slow moving inventories, obsolete or dormant stocks are brought to the notice of the Purchase Department so that such stocks may purchased future in lesser quantities as required. 10. The availability of correct figures of stocks helps in the insurance of the stocks.Control Ratios The control ratios are mainly two – (1) Inventory Turnover Ratio which we have studied and (2) Input-output Ratio. (1) Inventory Turnover Inventory Turnover is a ratio of the value of the materials consumed during a period to the average value of inventory held during that period. Certain materials are slow moving. It means their consumption rate quite show and so capital remains locked up and storing costs continue to be incurred in such materials if these materials are stored in excess of the requirement the rate of consumptions in terms of value or in terms of days is indicated by Inventory Turnover ratio. The number of days in which the average inventory is consumed can be ascertained by dividing the period by the Inventory turnover ratio. If the inventory turnover rate in terms of value of materials is high, or if the length of the inventory turnover BSPATIL 24
  • 25. period is short, the material is said to be fast moving. So if the rate of consumption is fast, or if the inventory turnover rate is good, it is a healthy measure of efficiency of materials control, as the capital employed is properly utilized.2. Input-output Ratio The Input-output Ratio is the ratio of the raw material put into manufacture and the standard raw materials content of the actual output. This ratio enables one to find out whether the usage of the materials is favourable or not. A standard ratio of input of materials and output of material should be determined and the actual ratio should be compared with the standard ratio.Pricing of Material Issues The pricing of issue of materials is not as simple as the pricing of receipts. As the issue are made out of the various lots purchased at different prices, the questions arises as how to price the issues, there are several methods used for pricing the issues and the selection of a proper method depends upon the following factors: 1. The type of work-job or process; 2. Range of price fluctuations and market trends; 3. The Inventory turnover period and the carrying or the non-carrying cost i.e., the frequency of purchases and E.O.Q. 4. The need for maintenance of uniformity is costs of the products within the industry. 5. The nature and durability of the material – whether it evaporates or shrinks, or absorbs moisture, etc.Method of Pricing The various methods used for pricing of the materials are:Cost Price Methods: 1. First in First out (FIFO) 2. Last in First out (LIFO) 3. Highest in First out (HIFO) 4. Base stock priceAverage price Methods: 1. Simple Average 2. Weighted Simple Average 3. Periodic Weighted Average 4. Moving Simple Average 5. Moving Simple Average 6. Moving Weighted AverageFirst in First out Method (FIFO): Under this method materials received first are issued first. After the first lot of the material purchased is over,the next lot is taken up for issue. As such, the materials are issued in the order in which they are received in the stores.The pricing of the issue of the first lot is done at the rate of purchase of the first lot. Similarly, the pricing pattern followsfor the subsequent lots. The closing stock in this method is valued at the latest purchase price and thus it represents thecurrent conditions as far as possible.Merits 1. It is simple to operate 2. The materials are charged at costs only. So the purchase price is recovered in full without showing any profit or loss on issue. 3. This method is good where a. The prices are falling; b. The consumption rates of the materials is slow 4. The Closing stock is shown at current rates.Demerits BSPATIL 25
  • 26. 1. It is not suitable in the situation when the prices show a rising trend, as it will charge the material at the lower rate than the replacement rate. 2. The same type of materials issued to two jobs at two different prices will show different costs. 3. If the prices fluctuate to much, the clerical errors may be many.Last in First Out (LIFO): Under this method, the material received last is issued first LIFO method and as such, pricing of issues is donein the reverse order of purchases. In times of rising prices, this method is considered best for application, as the currentcost of materials contributes to the cost of production.Merits 1. The material cost represents current prices except when the purchases were made long ago, 2. It is simple to operate and the pricing is done on cost basis 3. It relates current cost to current sale price, and enables the management to make correct decisions. 4. It is more useful when purchases are not too many and the prices are either steady or are rising. It is more suitable for bulky materials with high unit prices.Demerits 1. With high fluctuations in rates, the calculations become more complicated, and give way to more clerical errors. 2. The work of pricing is held up if the latest receipt rate is not readily available. 3. As in FIFO, costs of different batches of production are distorted and more than one price is adopted, in some cases, for pricing a single requisition. 4. Closing stock is valued at a cost which does not represent current conditions.Highest in First Out (HIFO): Under this method the material received at the highest price in the stock is issued first. This method is goodwhen it is desired to keep the inventory value of the materials at the lowest possible price.Base Stock Price Method In this method a minimum quantity of stock is always held at a fixed price as reserve in the stock. Thisminimum stock is known as base stock or the safety stock and is not used unless an emergency arises. This stock isvalued at long-run ‘normal’ price, while the stock in excess of this stock is priced on some other basis, usually are FIFOor the LIFO basis. It is not an independent method in itself a it is conjoined with either FIFO or the LIFO method.Simple Average Method The issue is prices at an average price and not at the exact cost price as in the earlier methods. The simpleaverage is calculated by dividing the total of the rates of the materials in the stock from which the materials to be pricedcould have been drawn, by the number of the rates of prices. This method can be used with advantage if (a) The purchase prices to not fluctuate considerably, and (b) It is difficult to identify the different issues of the materials.Weighted Average MethodMerits 1. This method irons out the wide fluctuations in the prices. 2. With every new issue, a new rate is not calculated. 3. The total value of the material issued does not behave up and down to the total value of the material received, as is the case with Simple Average Method.Demerits 1. Calculations are tedious. Prices are worked out in decimals to get correct results. 2. A lot of materials purchased at a very high price at one time continues to reflect its effect in the average, for a considerable time after it is exhausted. BSPATIL 26
  • 27. Periodic Simple Average Method This method is similar to Simple Average Method except that the average rate is calculated periodically, saymonthly or quarterly or once in the accounting period. If calculated monthly, the average of the unit prices of all thereceipts during the month is adopted as the rate for pricing issues during the subsequent month.Periodic Weighted Average Method This method is similar to Weighted Average Method except that the calculation is made periodically, say at aninterval or one month. The rate so arrived is used for the issues made in the next month.Moving Simple Average Method This represents a price which is obtained by dividing the total of the periodic simple average prices or a givennumber of periods, the last of the periods being that for which the materials are to be issued, by the number of periods.Moving Weighted Average Method This is just similar to the Moving Simple Average Method except that the periodic average price, in thissystem, is based on the weighted average.Problem 3 1) Show the Store Ledger entries as they would appear when using i) FIFO ii) LIFO iii) Weighted average method iv) Simple average methodApril 1.

  • 31. Chapter – 3 Labour Cost“Labour Cost, representing the human contribution to production, is an important cost factor which requires constantcontrol, measurement and analysis.” A rational approach to the problems of labour, fair maintenance of wage records for wage ascertainment, fairwage policy, and the incentives for earning more wages go a long way in providing a sense of security and stability tothe workmen, in minimizing the labour turnover, and in exercising effective labour cost control. Labour cost control aims at the control of the labour cost per unit of production and not at the reduction of thewage rates of the workmen.Efficiency of labour (a concept meaningless to material) has an important impact on the successful working of abusiness.Labour cost is second major element of cost. Proper control and accounting for labour cost is one of the most importantproblems of a business enterprise. But control of labour cost presents certain practical difficulties unlike the control ofmaterial cost.Labour costs represent the various items of expenditure Such as:Monetary Benefits: i) Basic Wages; ii) Dearness Allowance; iii) Employer’s Contribution to Provident Fund; iv) Employer’s Contribution to Employee’s State Insurance (ESI) Scheme; v) Production Bonus; vi) Profit Bonus; vii) Old age Pension; viii) Retirement Gratuity;Fringe Benefits: i) Subsidised Food; ii) Subsidised Housing; iii) Subsidised Education to the children of the workers; iv) Medical facilities; v) Holidays pay; vi) Recreational facilities.Economic utilization of labour is a need of the present day industry to reduce the cost of production of the productsmanufactured or service rendered.Control of labour costs is an important objective of management and the realization of this objectives depends upon thecooperation of every member of the supervisory force from the top executive to foreman. From functional point of view,control of labour cost is effected in large industrial concern by the coordinated efforts of the following six departments- 1) Personnel Department, 2) Engineering Department, 3) Rate or time and Motion Study department 4) Time-Keeper Department 5) Cost Accounting Department 6) Pay-roll DepartmentFactors Governing a Satisfactory system of Wage Payment BSPATIL 31
  • 32. The following factors should be considered while evolving a suitable and a successful system of wage payment. a) The system should depend upon the nature of the worked and the efforts involved. b) It should guarantee a minimum living wage to ensure a satisfactory standard of living. c) It should be based upon a scientific time and motion study. d) It should be capable of being understood by al the employees. e) It should be flexible and capable of being adapted to changed circumstances. f) Its incidence on the cost per unit should be such that it does not form a considerable proportion of the total cost per unit to deprive the employer of a fair margin of profit, given the market price of the commodity produced by concern. g) It should reduce the labour turnover. h) The cost of working the system should be the least. i) It should boost employee morale. j) It should be acceptable to trade unions. k) It should be correlated to the capacity of the concern to pay.For labour-cost-control, the following factors should also be kept in view while devising the system: 1. Production Planning: Production should be so planned as to have the maximum and rational utilization of labour. The product and process engineering, programming, routing, and direction constitute the production-planning. 2. Setting up of standards With the help of work study, time study and motion study are set up for production operations. The standard cost of labour so set is compared to the actual labour cost and the reasons for variations, if any, are looked into. 3. Use of labour budgets: Labour budget is prepared on the basis of production budget. The number and type of workers needed for the production are provided for along with the cost of labour in the Labour budget. This budget is a plan for labour cost and is based on the past data considered in future perspective. 4. Study of the effectiveness of Wage-policy: How far the remuneration paid on the basis of incentive plan fro the departments help the managerial control on labour and exercise labour cost control.Characteristics of Good Wage System 1. Fair to both the Parties: The system should be such as may be acceptable gladly to the employer and the employees. for this purpose, the employer should decide the system in consultation with the workers. 2. Easy to Calculate The workers should be in a position to calculate their wages correctly and feel sure that they have been correctly paid. Easy calculation will help the employer also in maintaining simple records. 3. Related to Efficiency ‘Fair remunerations for fair output’, should be the idea and remuneration should be related to the individual efficiency of the workers. 4. Minimum wage guaranteed There should be a guarantee of minimum wages to the workers to enable them to maintain their basic BSPATIL 32
  • 33. standards of life, and to do away with uncertainty-concept. 5. Incentive-oriented The wage system should be such that the workers may feel encouraged to product more and earn more wages. 6. Quality Improvement-oriented In the race to earn more wages with an increase in production, the chances are that the quality of the output may deteriorate. The system should, therefore, ensure ‘better wages for better quality’.Definite wage-base The basis or the method of wage payment should be clearly defined and announced in advanced to the workers,and it should not be changed frequently to suit the interest of the employer, otherwise a sense of distrust may develop inthe workers towards the scheme. A change in the system should be effected only after taking the workers intoconfidence.Labour Turnover Labour turnover is an index denoting change in the labour force for an organisatoin during a specified period. Inevery industry, works leave their job a new workers have to be appointed to replace them. The ratio of the replacedworkers to the number of works is the Labour Turnover Ratio. If more workers leave the factory, the turnover would behigh, and vice versa. A high turnover is a costly affair and must be avoided.Causes of Labour Turnover The workers leave the factory either by i) Resignation, or by ii) Discharge by the employer, or iii) Due to a cause not within one’s control.Cause for resignationThe causes may be: 1. Low wages paid as compared to the wages paid in other factory which he is induced to join. 2. Ill health and bad working conditions; 3. Lack of safety measures; 4. Dissatisfactions due to various causes such as a. Hours of work b. Improper placement c. Unfair method of promotion, d. Bad relationship with Supervisor, or with fellow-workers in some cases.Causes for Discharge 1. Incompetence; 2. Insubordination, disobedience, and disregard of the rules asn regulations; 3. Unpunctuality or lack of attention to duty; 4. Accidents or suffering from infectious disease; 5. Immoral character.Causes not within control 1. Seasonal character of the industry where work is carried on during some part of the year only; 2. Death of the worker;Measurement of Labour Turnover Labour Turnover is measured by applying any one of the following three Methods: 1. Separation Method BSPATIL 33
  • 34. Multiplication of the formula by 100 indicated Ratio of the turnover in percentage. 2. Replacement MethodIn this method, only the actual replacement are counted irrespective of the number of workers left. If new workers areappointed for expansion programme, they are excluded from the number or replacements. 3. Flux Method This method is the combination of Method 1 and Method 2.Effect of Labour Turnover on Cost The Labour Turnover in excess of normal rate is high turnover, and the turnover below the normal rate is lowturnover. It is always better to keep the turnover low, but it should nto be construed that the factories with low turnoverare always more productive. There may be low turnover in a factory for the reason that the workers engaged therein arebelow standard and so they cannot find better place in other factories. Secondly, low turnover in the senior scales maynot provide promotion factories. Secondly, low turnover in the senior scales may not provide promotion opportunities tothe young and promising employees and so they may like to shift to other factories for better prospects. A high turnover has an adverse effect on the cost of production due to the following reasons: 1. Change in workers interrupts production and the production goes down. 2. New comers take time in learning the factory procedure and the work procedure. 3. The tools and machines cannot be handled as efficiently by the new workers as hither to done by the old staff. There are chances of more break-downs and of greater cost of repairs of machines. 4. What is true of machines is also true of material handling and usage by the new workers. 5. The rate of accidents may increase, the rate of defectives in the finished output may increase, and there may be increased wastage of time. 6. The cost of making selections and cost of imparting training to the new entrants would further increase the cost and reduce the profits.Cost of Labour TurnoverThere are two types of costs i) Preventive cost and ii) Replacement costsAnd amenities to the workers that they may be tempted to continue at their job in the factory and not to leave it forexample: i) Personnel Administration: Only that portion of the cost of this department which is related to the maintenance of good relationship between labour and management. ii) Medical Services-Preventive as well as curative. BSPATIL 34
  • 35. iii) Welfare activities and services. iv) Miscellaneous schemes and benefits, e.g., Provident fund scheme, Pension scheme, Bonus incentives schemes, etc.The replacement costs are those incurred to recruit new workers and also the costs consequent or incidental toreplacement, for example: (i) Cost in selection and appointment (ii) Training cost (iii) Loss of output due to delay in recruitment workers (iv) Cost of inefficiency of new workers (v) Cost of breakage of tools and machinery (vi) Cost of increased spoilage and defectives (vii)Cost of frequent accidentsThe treatment of Prevention and Replacement costs is to charge them as overhead and apportion to the differentdepartments in the ratio of other workers.IDLE TIME The time when the worker does no work and remains idle, is the idle time. So the idle time cost represents thewages paid for the time lost. The following are its causes: 1. Lack of proper planning:That the production work should go on smoothly, depends upon proper planning. If the workers do not have material atthe right time, or the machines are not kept fir for working, the time goes waste. Sometimes, delay in the proceedingprocess delays the operations of the succeeding progress. Here also the workers have to wait due to faulty planning orbad management. 2. Careless in Supervision:If the foreman of a department does not take his duty seriously, the labour working under him also becomes careless andspoils time in the idle way. 3. Confrontation between labour management:The confrontation between labour and management arising form any cause, does waste time in discussions, dialogues,strikes etc., and the wages paid, if any, for this period form the idle time cost. 4. Economic Factors:Trade depression, or serve competition lowers the production, and so labour remains effectively unutilized. 5. Others reasons:The electricity may fail or the machine may break down for some or more time. They make labour to remain idle for thetime being.Idle time does not limit itself in its effect to the wages paid for the time but his wider implications. The plant, machines,equipments, and other accessories also become idle during that period, and the fixed cost continues to be incurred. Assuch, idle time need be reduced as far as possible.Idle-time cost can be divided into two types: (i) Normal, and (ii) AbnormalNormal idle-time can be further divided into a) Controllable, and b) Uncontrollable.Normal idle-time is one which is incidental to production. The cost of normal and controllable idle time should be BSPATIL 35
  • 36. charged as an overhead expense to the production. If the responsibility for this type of idle-time can be fixed upon aparticular department, the cost should be charged to the overheads of that department and absorbed in the productioncost of that department.OVER-TIMEThe time worked over and above the normal hours is overtime. The remuneration usually paid for the overtime work isat double the normal rate. The need for over time work arises due to: 1. Increase in demand for the products where the production during the normal hours falls short to meet it; 2. Shortage of workers due to absence or non-availability and so it is decided to give overtime work to the existing staff; 3. Utilization of perishable raw materials by working overtime; 4. Execution of urgent orders, or to complete the work o9n the same day; 5. Shortage of equipments, machines, or space for the completion of jobs; 6. Lack of administrative control on workers, on account of which the production during normal hours remains less the standard output and overtime work has to be done by the workers.Disadvantages of overtime working The following are the disadvantages: 1. Worker’s health is adversely affected; 2. The quality of the output is at a discount; and 3. The cost of production rises due to increased labour cost.System of Wage Payment Strictly speaking, there are only two basic methods of wage payment, viz., wages based on the time spent in thefactory, and wages based on the quantum of work turned out. These are thus known respectively as the ‘time wage’ andthe ‘piece wage’ methods of remuneration. Since each of these has its own advantages and disadvantages, attempts aremade to combine the two, mainly with a view to overcoming their disadvantages. We have therefore, the premium bonusor the incentive schemes which may either be considered to be merely variations of the two, or as another of wagepayment. These three methods may also be re-classified into only two groups, viz., the time wage system and thepayment by results.Methods of RemunerationThe methods of remuneration can be classified into: 1. Time Rate System 2. Pieced Rate System 3. Incentive SchemesTime Rate System In this system, a worker is paid on the basis of attendance for the day or according to the hours of the day,regardless of the output. This system is also known as time work, day work, day age rate or day rate. The wage rate ofthe day worker may be fixed on hourly, daily, weekly, fortnightly, or monthly basis depending on the practice followedin the concern. The basic feature of this system is that the worker is paid so much per unit of time regardless of the output heproduces. The unit of time may be an hour, a day, a week or a month. Under this method, wages depend entirely uponthe time clocked, but not on the efficiency of the worker. There are three variants of this system, each differing only inso far as the fixation of the time rate is concerned. They are: a) Flat Time or Time Rate at Ordinary level; b) High Day Rate or Time Rate at high level; c) Measured Day work or Graduated Time Rate. BSPATIL 36
  • 37. Graduated Time Rate Under this method wages are paid at time rates which vary according to a. Merit-rating of the workers, or b. Changes in the cost of living index.It the cost of living goes up, the wages also go up proportionately, and vice versa. Thus the works get the real wages.Similarly, the workers having higher merit rating get higher wages, and the workers with lower rating get lower wages.Differential Time Rate Workers are paid rate accounting to their individual efficiency. They are paid normal rate upto a certainpercentage of efficiency and the rate increases in steps for efficiency slabs beyond the standard. As the efficiency ismeasured in terms of output, this method does not fall strictly under the area of time rate system.Payment by Results-Piece-work Rate The payment of wages under this system is based upon the out turn of the worker. The rate is fixed per piece ofwork and the worker is paid according to the pieces of work completed or the volume of work done by him, irrespectiveof the time taken by him in completing that work. A workman is free to earn as much as his ability, energy, or skillwould allow to him to produce. The various schemes falling under ‘Payment by results’ make speed as the basis of payment, instead of time.Accordingly, these schemes are just the opposite of the time wage system. They are so called because of the fact thatwages are linked to the volume of work done regardless of the time taken by workers. Efficiency is recognized in allthese schemes and workers get wages according to their avility, efficiency, and speed. The following schemes fall underthe payment by results method of wage payment. a. Straight Piece Rate. b. Differential Piece Rate.Stability of the System This system is suitable in the following cases: 1. Where the production can be measured in standard units. 2. Where strict supervision is not possible. 3. Where quality and precision are not of primary importance.Advantages 1. It provide initiative and incentive to the workers to product more. 2. The productivity increases and cost of production per unit goes down. 3. As there is little wastage of time on the part of the workers, the fixed overheads and resources like plant, machinery and space are well utilized. 4. Workers feel free to work, complete with fellow workers, exhibit their efficiency, and earn more of wages. 5. Less supervision is required over the workers, and happy relations are maintained with them. 6. It is easy to calculate the labor of products.Disadvantages 1. In the race to earn more wages by producing more, the quality of products is likely to deteriorate. So it requires strict inspection and quality control. 2. Continuous and increased working for some days may cause fatigue and ill health to the workers. 3. To speed up production, the machines, tools, and equipments are sometimes not handled with the care that they require, and so the workers expose themselves to accidents, besides causing loss of breakdown to the machines, equipments etc., BSPATIL 37
  • 38. 4. The inefficient workers earning less of wages start feeling jealous of other workers who earn more. This creates unhealthy atmosphere. 5. The workers feel insecure of earning during the days of ill health, holidays, etc. 6. This system is not useful for quality products.The piece rate System can be classified into:Straight Piece Rates It is a simple method of making payment at a fixed rate per unit for the units manufactured.Earnings = Number of units X Rate per unitThe rate is fixed taking into consideration a. Time rate for the same class of workers, and b. Standard output during a given time.Differential Piece Rates Under this system, efficient workers are paid wages at a lower rate. A definite standard of efficiency is set foreach job and for efficiency below or above the standard different piece rates are paid according to different levels ofefficiency. The following two methods of wage payment are studied under this system: a. Taylor Differential Piece-rate Method, and b. Merrick Differential Piece rate MethodTaylor Differential Piece-Rate F.W. Taylor thought to improve the efficiency of workers by suggesting two rates of payment of wages: (I) A higher rate to the workers who product equal to or more than the standard fixed for production during the day, and (II) A lower rate to the workers who do not achieve the standard.Merrick Differential Piece-rate In the Taylor Method, the effect on the wages is quite sharp in the marginal cases. To remove this defectMerrick suggested three piece rates for a job as follows:Percentage of Standard Output Payment under Merrick MethodUpto 83% Normal piece rateAbove 83% and upto 100% 110% of normal piece rateAbove 100% 120% of normal piece rateIncentive SchemesFactors for Selecting Incentive SchemeThe following factors should be considered for selecting an incentive scheme: 1. Productivity The object of the incentive scheme is to increase productivity. Therefore, this factor is very important. The increased BSPATIL 38
  • 39. productivity lowers the cost to the benefit of the employers. 2. Simplicity The scheme should be simple in operations and well understood by the workers. The scheme should be amenable to the setting up of standards and the comparison of the results with the actual. 3. Cost Reduction The scheme, when introduced, is bound to increase the pay-bill of the workers, and thus increase the cost. But the simultaneous increase in production would reduce the cost per unit or production. The fixed overheads remain constant up to a certain limit of plant capacity. As such, the increased productivity reduces the cost of fixed overheads per unit. 4. Better Labour Psychology The scheme should not affect worker’s health adversely, should reduce labour turnover and help to improve the standard of living of the workers. Under this heading, we study the following methods: (I) Halsey Premium Scheme; (II) Halsey Weir Scheme; (III) Rowan Premium Scheme;Halsey Premium Scheme Under this plan, (i) Time rate is guaranteed; (ii) Standard time is fixed for the job or operation; (iii) The workers producing more than the standard, or the workers completing the work in less than the standard time fixed, get bonus in addition to the ordinary time wage; (iv) The bonus of the premium, by whatever name called, is 30 to 70 percent of the wages of time saved, the usual percentage being 50%, (v) The remaining of the bonus percentage is shared by the employer.Merits of Halsey Plan (i) Day wage or the time rate is guaranteed. Even if output is less than the standard, one gets the time wage; (ii) Workers get premium for the output above the standard. It provides incentive to the workers to produce more; (iii) As the premium is not 100% but only 50% or so, the employers feel happy about it is a they share the remaining 50%; (iv) The scheme is very simple and understood easily by the workers.Demerits (i) A significant share of the bonus goes to the employers. So the workers object to it; (ii) Incentive is not so attractive as it is with the piece work; (iii) Where the workers start saving more than 50% of the time, they earn premium in huge amounts, which the employers do not relish.Halsey – Weir Scheme This schedule is similar to Halsey scheme except that in this scheme the workers and employers share the BSPATIL 39
  • 40. premium in 1:2 ratio.Rowan Premium Scheme (variable sharing plan) Mr. James Rowan introduced this scheme in Glasgow in 1898. It is similar to Halsey scheme but the premiumconcept here is different. Here the premium is in the ratio of Time saved to Standard time, calculated on the ordinarywages.Premium = Wages of time worked x Time saved / Standard Time Or; (AT x R) TS / STThis scheme also guarantees day wage as is done by Halsey Plan.Problem 1Calculate the earnings of a worker from the following information as under.a) Time Rate Method: Standard time 30 hours Time taken 20 hours.

Lesson – 4 OVERHEAD COSTOverhead is “the aggregate of indirect material cost, indirect wagers (indirect labor cost) and indirect expenses”.Classification of OverheadsThe Overheads can be classified according to: i) Elements; ii) Functions; iii) Behaviour; iv) Controllability;Element-wise classification Overhead Materials Cos is the which cannot be allocated but which can be apportioned to, or absorbed by, costcentres or cost units. Consumable stores, lubricating oil, loose tools, cotton waste, etc. are the examples. Indirect Labour Cost is the cost of wages which cannot be allocated but which can be apportioned to, orabsorbed by, cost centres or cost units. Salary of foremen, supervisors, works manager, storekeepers, etc. Wages ofmaintenance dept. employer’s contribution to provident Fund, overtime wages, etc., are the examples. Indirect Expenses are the expenses which cannot be allocated but which can be apportioned to, or absorbed by,cost centres or cost units. Factory rent, lighting, heating, depreciation, insurance, other factory expenses, alladministrations, selling, and distribution expenses fall under this group.Overhead is divided according to functions into: i) Production or Manufacturing Overhead; ii) Administration Overhead; iii) Selling Overhead; iv) Distribution OverheadProduction Overhead It includes all overheads incurred from the stage of procurements of materials till the completion of themanufacture and the primary packing of the product. 1. Rent, municipal taxes, depreciation, insurance, etc., of the factory land and building. 2. Depreciation insurance etc. of the factory plant, machines and equipments. 3. Factory lighting, heating and air conditioning; 4. Fuel and power; 5. Consumable stores, small tools, etc,; 6. Indirect materials, such as cotton waste, lubricating oil, brushes etc.; 7. Repairs of factory building, plant, machines and equipments. 8. Store-keeping expenses; 9. Cost of idle time, overtime, holiday pay etc. 10. Salary of foremen, timekeepers, works manager etc.; 11. Repairs and maintenance of Power house; 12. Other expenses, e.g., Worker’s training and welfare, Inspection, Research and Development, Factory telephone and Stationary etc.Classification According to Behaviour BSPATIL 49
  • 50. Fixed Overheads Fixed overheads is one which tends to be unaffected by variation in volume of output. This overhead remainsconstant, i.e., does not change with the increase or decrease in production, within a certain range. The fixed overheadsare related to the periods, and so the fixed costs are also known as Period Costs, e.g., the rent of the building or thesalaries of the office staff.Variable Overheads The variable overhead is one which tends to vary directly with volume of output. The variable cost increases indirect proportion with the increase in production, and decrease in production. It is known as Direct cost. Salesman’s Commission; Discounts to customers; Bad debts; Branch expenses; Postage; Stationery; Travelling;Salesman’s expenses; Packing charges; Carriage outward; Variable expenses on delivery vans; etc. It means that a part of the expenses does not change while the other part of the same expense charges withvolume of output. Generally, on costs are truly fixed or truly variable.Classification According to Controllability The overheads can be classified on the basis of controllability into a) Controllable, and b) Un-controllable. The controllable cost is one which can be controlled, i.e., maintained or reduced. The variable costs fall underthis category. The un-controllable cost is one which cannot be influenced by the action of a specified member of theundertaking.Allocation of cost Allocation of cost means charging the full amount a cost to a cost centre, i.e. to the job, process, or to theproduct etc. The nature of the expense is such that it can easily be identified and allocated to the cost centre or to the costunit of production.Apportionment of cost Where the expense is a common one and it is to be allotted to different cost centres proportionately on anappropriate basis, it is known as ‘apportionment’. For example, rent of the factory is an expense which cannot beallocated to any one department, but is to be shared by all the production departments and service department, onsuitable basis, e.g., floor area basis.Absorption of Overhead With the help of allocation and apportionment, the different production departments get their due share of thetotal production overheads. After that, the process of absorption starts. The overheads of a particular department are tobe allotted to the production units of the department. This allotment to the unity is absorption.Ability to Pay Principle, Efficiency or Incentive principle: Overheads is to recover or absorb the overheads in the cost of products, individual jobs, processes, batches, orother convenient units. The overheads falling to the share of a department through the process of allocation orapportionment, is to be absorbed by the cost units of that department. This is known as ‘Absorption of overheads’.Problem 1 BSPATIL 50

Absorption of overhead cost Absorption means allotment of overhead cost of jobs i.e., with a view to charging the same amount of overheadsin respect of the departments of cost centre where it is spent.Methods of Absorptions There are various methods of absorptions, some of which generally used are given below: a) Direct Labour Cost Method. b) Direct Labour Hours Method c) Machine Hour Rate d) Prime Cost Method e) Conversion Cost MethodMachine Hour Rate MethodThis Method is applicable where work is carried on mostly by the machines because the overheads in such a case aremore related to the machines. The factory overheads of the factory are ppportioned to the different machines or group ofmachines. An individual machine is treated to be a cost centre, and sometimes a group of machines which work togetherin Co-operation is treated to be a cost centre fro the purpose of apportionment. The working hours of a machine arecalculated for the period for which the machine is to run. Machine hour rate is scientific, practical and accurate. It helpsin finding out idle machines cost and also in decision making.Problem 5Workout the machine hour rate for the following machine, whose scrap value is nil: 1. Cost of Machine Rs. 90,000 2.

In this method is also known are separately indentified and are coasted individually. Jobcosting is applicable to job printers, engineers, furniture makers, builders, contractors, hardware and machinemanufacturing industries, repairing shops, etc. The Costing Department prepares job cost sheet (Fig. 2) for each job, containing the production order No., andother details relating to the job. Where a job requires several major operations or components, sub-cost sheet. The jobcost sheet is the document detailing the cost of the job under Direct material. Direct labour, Works overheads etc., It isnot prepared for a specific period but for a specific job. The cost of all the job in process are debited to the Work-in-Progress Control Account. On the completion of ajob, this account is credited and Finished Goods Control Account is debited with its cost. The difference between thecost and the price charged is the profit or the loss on the job. On the completion of a job Completion Report is submitted by the production shop to the planning Departmentwith a copy to Costing Department. This report is an indication that further expenses on the job should cease and the jobcost sheet be closed.Problem 1 Find out in the suitable cost sheets form the selling rater per tone of special paper manufacturing by a paper millfor a private firm a January 1997 under the following divisions of cost: a.

This enable the management to know the trend of the costs and this by the efficiency of operations.  On completion of a job, the cost under each element is immediately ascertained. Cost may be compared with the selling prices of he products in order to determine their profitability and to decide which product lines should be pushed or discontinued or whether prices or price quotation could be revised. The application of marginal costing techniques may be useful in such situations.  Historical costs for past periods for each product, compiled by orders, departments, or machines, provide useful statistics for future production planning and for estimating the costs of similar jobs to be taken up in future. This assists in the prompt furnishing of price quotations for specific jobs.  The adoption of predetermined overhead rates in job costing necessitates the application of a system of budgetary control of overhead with all its advantages.  The actual overhead costs are compared with the overhead applied at predetermined rates; thus at the end of an accounting period, overhead variances can be analyzed.  Spoilage and defective work can be easily identified with specific jobs or products so that responsibility may be fixed on determents or individuals.  Job costing is particularly suitable for cost-plus and such other contracts where selling price is determined directly on the basis of costs. BSPATIL 64
  • 65. Limitations of job costing: • Job costing is comparatively more expensive as more clerical work is involved in identifying each element of cost with specific departments and jobs. • With the increase in the clerical processes, chances of errors are enhanced. • The cost as ascertained, even where they are complied very promptly, are historical as they are compiled after incidence. • The cost compiled under job costing system represents the cost incurred under actual conditions of operation. The system does not have any scientific basis to indicate what the cost should be or should have been, unless standards of performance efficiency are established. Estimated cost, prepared by some concerns in respect of job orders, also do not serve the purpose. • If major economic changes take place, comparison of cost of a job for one period with that of another becomes meaningless. Distortion of cost also occurs when the batch quantities are different.BATCH COSTING Batch costing a modified from of job costing. While job costing is concerned with producing articles accordingto customer’s requirements and specifications, batch costing is used where the articles are manufactured in a goodnumber in definite batches. Component parts of watches, radio sets, television sets etc., are extensively produced underbatch costing, for being assembled in the product. If one component of a special design is ordered by a customer formanufacture, it is Batch costing, Batch costing, therefore, is also known a “Lot Costing”. A batch of workers is assigned to perform the task of producing a certain number of articles in a particularperiod. Thus the cost of production can be compared batch wise, and efficiency ascertained. Like job order system, onenumber is allotted to each batch. The material requisitions are prepared batch wise, labour is engaged batch wise, andthe overheads are also charged batch wise. This it is a modified form of job costing. The cost control in batch costing depends upon ascertainment of the optimum number of batch production. TheEconomic Batch Quantity can be decided on the same principle and same formula as applied to Economic OrderQuantity is case of materials. Cost comparison between the two batches is possible if both batches are allowed the same facilities, time toproduce, and the same number of articles. The comparison can be fruitfully done with the help of cost sheets of the twobatches.Problem 1 A joining factory has undertaken to supply 200 pieces of a component per month for the ensuing six months.Every month a batch order is opened against with material and labour hours are booked at actual.

  • 67. Lesson – 6 CONTRACT COSTING Contract is an agreement enforceable by law. It is an agreement between two parties – Contractor and theContractee. The contractor agrees to undertake and complete the work, as per terms of contract, within a specific periodand for a particular monetary consideration. The terms of contract regarding work to be undertaken, period in which tobe completed, value of the contract advances to be made by the Contractee to the contractor on the certificate ofarchitect, compensation payable by the contractor for the breach of contract, etc., are decided upon between the twoparties before the work is started. These contracts related to the works of construction of roads, buildings, bridges, damsand banks, ports, etc, Contract costing is the technique of ascertaining cost of a contract. Here the unit of cost is one only, e.g., abuilding, or a bridge etc. it is similar to job in principle, and so the method of recording cost is the same. A ContractLedger book is kept in which a separate account for each contract is opened. The following items appear on the debit side of the Contract A/c: 1. Direct Materials 2. Direct Labour 3. Direct Expenses 4. Overheads 5. Plant and Machinery 6. Sub-Contract Cost 7. Extra Work doneThe following items appear on the credit side of the Contract A/c: 1. Materials Returned 2. Materials Transferred 3. Materials at the end 4. Plant and Tools at the end 5. Work Certified 6. Work done but Uncertified 7. Contract PriceWork Certified As per terms of the contract, the contractee advances some 80 or 90 percent of he work done to the contractor onthe basis of the work certified by the contractee’s architect or engineer periodically. The balance of 20 or 10 percentamount is retained by the contractee, so that the contractor may continue to work and not leave the contract if thecontract is not proving to be profitable one to him. The amount retained is known as ‘Retention of Money’.Work done but not yet Certified A work done by the contractor but which remains to be certified by the architect on the date of accounting isknown as work done but not yet certified.Contract Price The contract price is the value of contract agreed to be paid to the contractor by the contractee on thesatisfactory completion of the contract. So on the completion of the Contract the Contract A/c is credited with thecontract price and ‘Contractee’s A/c’ is debited.Cost – plus – contract Where a contractor feels hesitant to quote for a work of contract which is absolutely new to him, and new toother contractors as well, and he is unable to estimate the cost of the works offered to him for execution. It is decidedwith the contract or that he would be paid the total cost of work whatever it be, plus his profit as a rate percent on thetotal cost. Such s contract is known as ‘Cost – plus – Contract’. BSPATIL 67
  • 68. Ascertainment of Profit/Loss on Contract The Profit/Loss on contract is ascertained as follows: a) On completion of Contract: The excesses of credit over the debit items of the contract a/c is the profit, and the whole of it can be taken into account. The excess of debit over the credit items is loss. b) On incomplete Contract: Where a contract takes more one financial year for in to complete, it is usual to take into account a part of the profit only to the Profit and Loss Account. If there is a loss, the whole of the loss is transferred to the P & L A/c.What part of the notional profit should be credited to the profit and loss account each year, depends on the practice andcircumstances of the case. The general rules are: a) If the value of certified work is less than 1/4th of the contract price, no profit is taken into account, and the balance of the contract a/c is transferred to the Work-in-Progress A/c. b) If the certified work is 1/4th or more than 1/4th, but less then ½ of the contract price, only 1/3 of the computed profit as reduced to the cash basis (cash received on work certified), should be credited to the Profit and Loss Account. The formula is:Profit = Computed profit, i.e. Cr. Balance of contract a/c x 1/3 x (cash received / work certified)The balance of the computed profit is a reserve and is transferred to Work-in-Progress A/c. c) If the value of certified work is ½ or more than ½ of the contract value, 2/3 of the computed profit as reduced to the cash basis is credited to P & L A/c.Problem 1(Where more than ½ contract is complete)Building Contractors Ltd., undertake contracts.

On deducting the estimated total cost from thecontract price, we get the notional or the computed profit. Of this computed profit only that part is credited to P & L A/cas is reduced by the proportion of. (i) ‘Work credited’ to ‘Contract Price’ or more conservatively. (ii) ‘Cash received’ to ‘Contract Price’ so: i. Profit = Estimated Profit on completed contract x Work certified / Contract Price ii. Profit = Estimated Profit on completed contract x Cash Received / Contract Price.An Estimated Contract A/c or Estimated Contract Statement is required to be prepared to find out the estimated cost ofthe full contract and to find out the national profit for the purpose of calculating the Profit to be credited to the Profit andLoss Account in the main Contract A/c.Work-in-progress and Balance Sheet The Work-in-progress A/c is debited with the sums (i) Work certified (valued at contract price), and (ii) Work done but not yet certified (valued at cost).This account is credited with the balance of the notional profit not taken to the Profit and Loss Account.This account shows debit balance which is taken to the Balance Sheet on the Asset side.

  • 73. Lesson – 7 PROCESS COSTING Process costing is the type of costing applied in industries where there is continuous or mass production. Thenecessity for compilation of the costs of a process or a department for a given period, as distinct from the cost of a wholejob or a specific batch of production units, has given rise to the concept of process cost accounting. There are manyindustries engaged in continuous processing in which the end products are the results of a number of operationsperformed in sequence. In such industries, it is necessary to apply process costing. Process costing is suitable for a large number of mining, manufacturing and public utility industries like minesand quarries, cotton, wool and jute textiles, chemicals, soap making, paper, plastics, distillation processes, e.g. alcohol,tanning, oil refining, screws, bolts and rivets, canning, food products, dairy, and electricity and gas undertakings.Features of Process Costing:- 1. The production is continuous and the end product is the result of a sequence of processes. 2. The product is homogeneous and the units product are identical and standardized. 3. The sequence of operations for processing the product is specific and predetermined. 4. The finished products of one process works as raw material for the next or process until completion.Process Costing and Job Costing:- A comparison of the basic principles of process costing with those of job costing, given below, will assist inappreciating process costing procedures. Job Costing Process Costing 1. Production is by specify orders 1. Production is in continuous flow, the products being homogeneous. 2. Costs are determined by jobs or 2.

The unit cost of a process, which is dividing the total cost incurred into the computed by dividing the total cost for units produced in the lot or batch. the period (after adjustment of the opening and closing work-in-process), is an average cost for the period. 5.

Process production is standardized production is not continuous, more and is more stable. Hence, control of managerial attention is needed if process activities is comparatively proper control is to be exercised. easy.Advantages and Limitations of Process Costing:-Process costing has the following advantages: (i) Process cost may be determined periodically at short intervals. When predetermined overhead rates are in use, it may be possible to complete unit cost weekly or even daily. This not always so under the job costing system, particularly when jobs run for long periods and there are no significant units of completed production during the various accounting periods, falling between the total period of run of the jobs. (ii) It involves less efforts and less clerical expenses as the accounting method is simpler than that in job costing. (iii) Detailed cost, budgeted as well as actual, are made available for each possible by evaluating the performance of each process etc. (iv) Allocation of overhead to departments and processes can be made fairly accurately on definite bases. (v) Since the material consumption ass the various operations are more or less standardized, more accurate cost estimates are available for price quotations. (vi) It is easier to set effective and fairly stable standards in case of mass production or continuous repetitive production. Process costing situations are, therefore, more adaptable for installing standard costing procedures.The limitations and weaknesses of process costing systems are as follows:- (i) Being only average costs for the accounting period, process cost cannot be considered to be very accurate for the purpose of detailed analysis, evaluation, and control of individual performance efficiency on a day-to-day basis. (ii) Costs obtained at the end of the accounting period are only historical and are not of much use for effective control unless standard process cost are used. This is, no doubt, true in respect of all other historical systems but the nature of process accounting with its departmental divisions makes this disadvantage more prominent. (iii) When different products come out of one and the same process, the common costs are prorated to the various products. Such cost of individual products are not reliable as they may, at best, be taken to be only approximations. (iv) For the purpose of calculation of unit costs of continuous processes, work-in-process is required to be determined at the end of an accounting period. This is done mostly on estimated basis which introduces further inaccuracies in costs.Process Costing Procedures:-The procedure for costing applicable to processes or departments will very in details according to the requirements ofproduction methods. The various situations and problems envisaged and the methods of calculation of costs in respect ofeach of the situations have been discussed under the following heads: 1. Single process production 2. More than one process involved; output of one process transferred in full to the subsequent process. 3. Output of a process partly transferred to the next process and partly retained in stock. 4. Process consisting of opening and closing stock, fully completed. BSPATIL 74

The value of the abnormal gain is calculated in the same way as described above forabnormal loss and is credited to an Abnormal Gain Account which is ultimately closed. Profit and Loss Account. Thescrap value of the normal anticipated loss in the process where abnormal gain occurs is credited to the process accountwith the result that the net debit to the process is the cost of abnormal gain less the value of scrap for the normal loss.Problem 3:(Normal wastage – Loss in weight and sale of scrap) The Bengal Chemical Co.

  • 93. LESSON – 8 STANDARD COSTING & VARIANCE ANALYSISSTANDARD COST & STANDARD COSTINGStandard cost is a “predetermined cost which is calculated from management standard of efficient operation and therelevant necessary expenditure.” - I.C.M.A ENGLANDStandard costing is “the preparation of standard costs their comparison of actual costs and the analysis of variances totheir causes and points of incidence” - I.C.M.A ENGLANDThus, it is clear from these definitions that standard costs represent the scientifically planned or predetermined costsbased on technical estimate, labour and overhead for selected period of time and for a prescribed set of workingconditions. The word ‘standard’ connotes a thing serving as a basic for comparison. Standards can be established inrespect of quantitative and qualitative like material and labor.OBJECTIVE OF STANDARD COSTINGThe main objectives of standard costing are:-To control the factors which affect production.- to supply reports promptly to the management showing the progress of production and how expenditure to datecompares with estimates so that corrective actions may be taken in time, and- To disclose the effect of temporary increase or decrease in the volume of output and sales or revenues.TECHNIQUES OF STANDARD COSTINGThe technique of standard costing involves:- The ascertainment of standard costs.- The use of standard costs.- Their comparison with the actual cost and the measurements of variances.- the location of responsibility for the variances and the corrective action to be taken.- the analysis of variances for ascertainment the reasons for the same.ESTABLISHMENT OF A STANDARD COSTING SYSTEM The installation of standard costing system in a manufacturing concern involves the following steps: a) Standardization of functions i.e. all activities should be standardized and the technical processes of operations should also be susceptible to planning. b) Establishment of cost centres. c) Classification of Accounts i.e., the different accounts can be codified and different symbols may be used to facilitate speedy collection, analysis reporting. d) Setting up of standards: Standards may be basic (long period) and current (short period), From the point of view of efficiency level they will fall into the three broad categories. BSPATIL 93
  • 94. i) Strict ideal ii) Attainable or expected / actual and iii) LooseThe standard should be realistic and attainable. Unrealistic standards provoke resentment and depress performance.Loose standard leads the management to indulge in self congratulation. Normally a period of one year is more realisticas it coincides with the budget period and the normal accounting period. e) Setting of standard costs:Standard costs should be determined for each element of cost separately and accurately. Like the budget committee orstandards division which will be versed with the work of the standard costs. the standard committee generally consists ofall functional heads like production manager, personal manager, etc. In determining the output regard must be had to thelimiting factors affecting sales, production etc. setting up of standard cost involves the determination of cost standards.A cost standard is a usage, price or other standard upon which a standard cost is based.ADVANTAGES OF THE STANDARD COSTINGThe utility of standard help the management in fixation of prices and in laying down production policies. 1. Standards costs help the management in fixation of prices and in laying down production policies. 2. The help in readily showing up and then elimination of avoidable wastages and losses. 3. They provide constant and uniform bases for management on the operational efficiency of workers and other members of the staff. 4. Management, through the study of variances, needs to concentrate only areas and problems which call for its attention i.e., the system management by exception’ can be practiced. 5. Delegation of authority becomes effective the concerned men know what they have to achieve and by what standard they will be judged. 6. The whole concern in stimulated with a dynamic forward looking mentality. 7. Performance of employees at all levels can be judged objectively, this enables the concern to promote and regard the right person. 8. Standards act as a ‘yardstick’ to measure the actual performance and the efficiency of labour and other factors. 9. Valuation of closing stock is facilitated by the standard cost of production. 10. As standards are set for every element of cost, the costing procedures are simplified.LIMITATIONS OF STANDARDS COSTINGStandard costing technique has the following short comings. 1. Setting of standards is a difficult task as it involves technical skill. 2. The fixation of inaccurate standards especially those that are incapable of achievement adversely affects the morale of the employees and act as hindrances to increased efficiency. 3. The system is not suitable for the jobbing type of industries producing articles according to customers specifications even if it is installed, the fixation of standards for type of job becomes difficult and expensive. 4. It is necessary to distinguish between controllable and uncontrollable variances in order to localize deviations and fixing responsibilities. 5. The system may not be suitable even in the case of industries that are liable to frequent technological changes BSPATIL 94
  • 95. affecting the conditions of production even if it is installed, a constant revision of standards become necessary. 6. Small concern cannot afford this system due to higher cost associated with standard costing. 7. There is no unanimity regarding the circumstances to be taken as the basis for setting standard costs. even if there is unanimity a revision of standard is essential to suit to the changing circumstances. The revision of standards becomes expensive. If they are not revised, they become outmoded.DETERMINATION OF STANDARDSFor any given product or unit the following standards must be determined. 1. Standard material costs. 2. Standard labour costs. 3. Standard direct costs. 4. Standard variable overhead costs 5. Standard Fixed over head costs. 6. Standard selling prices and profit.The standard direct material cost is found by multiplying the quantity of materials to be purchased with the rate of priceat which they are available.Determination of standard labour cost involves fixations of (a) Standard labour grades (b) Standards labour times i.e., standard hours through time, motion and fatigue study with the help of work study engineers and (c) Standard wage rates based on the time rate, piece rate and premium plans.Standard direct cost is any expenditure which is directly to be incurred on a specific cost unit. It is charged directly tothe particular cost standard concerned.Standard overhead costs are classified as manufacturing, administration, selling, and distribution over heads. They arealso classified as fixed, variable and semi variable so that current estimate for each class may be prepared for the budgetperiod. Standard overhead rate is determined on the basis of past records and future trend of prices.VARIANCE ANALYSISThe main aim of the standard costing is the control of the cost. So the management is provided with the informationabout situations where in the actual results are not as they were planned to be. Hence management is informed of onlythe deviations or variances from the original plans, their favourable or unfavorable nature and the causes of suchdeviations. In this context standard costing subscribes to the principles of “management by exception”.Variance is the difference between standard cost and actual cost. It is expressed by a simple formula as follows:variance = actual cost – standard cost.Variance analysis is therefore the process of analysis variance by dividing the total variance in such a way thatmanagement can assign responsibility for off standard performance. If variance is to increase the profit it is said to befavourable shown as (F). It would result when the actual cost are lower than the standard costs. It is also known aspositive or credit variance and viewed only as savings. If variance is not to increase the profit it is adverse orunfavorable shown as (A) it would result when actual costs exceed the standard costs. It is also known as negative ordebit variance and viewed as additional costs or losses. 1. MATERIAL NOT VARIANCE (MCV)This is the difference between the standard cost of materials specified for the output achieved and the standard cost ofthe materials used BSPATIL 95
  • 96. Material Cost Variance = Total std. – Total Actual Cost. MCW = (SQ*SP) – (AQ * AP)Where : SQ = Standard Quantity SP = Standard Price AQ = Actual Quantity AP = Actual Price a) MATERIAL PRICE VARIANCE (MPV)This is the difference between the standard price specified and the standard price paid.MPV = AQ (SP – AP)CAUSES 1. Change in basic purchase price of material. 2. Change in quantity of purchase or uneconomical size of purchase order. 3. Rush order to meet shortage of supply or purchase in less or more favourable market. 4. Failure to take advantage of off – season price, the failure to purchase when price is cheaper. 5. Failure to obtain cash and trade discounts or change in the discount rates. 6. Weak purchase organisation. 7. Payment of excess or less freight 8. Transit losses and discrepancies if purchase price is inflated to include the loss. 9. Change in quality or specification or materials purchased. 10. Use of substitute material having a higher or lower unit price. 11. Change in materials purchase, unkeep and store keeping cost (this is applicable only when such charges are allocated to direct material costs on a predetermined or standard cost basis.) 12. Change in the pattern or amount of taxes and duties. b) MATERIAL USAGE VARIANCE (MUV)This is the difference between the standard quantity specified and actual quantity used.MUV = SP (SQ – AQ)Material usage variance is subdivided into i) Material mix variance ii) Material yield variance or scrap variance i) MATERIAL MIX VARIANCE (MMV)This is the portion of the direct material usage variance which is due to the difference between the standard and theactual composition of a mixture. BSPATIL 96
  • 97. a) When the ratio of mix is different but the total quantities of standard mix and the total quantities of actual mix are the same. MMV = SP (SQ – AQ) b) When the total actual quantity and total standard quantity and the ratio of mix are different, then the standard quantity of the each material will be revised. MMV = (RQ – AQ) * SP Where RQ denotes Revised standard quantity, which is equal to Total weight of actual mix --------------------------------- * Standard Quantity Total weight of standard mix ii) MATERIAL YIELD OR SCARP VARIANCEThis is the portion of the direct material usage variance which is due to the difference between standard yield specifiedand actual yield obtained.MYV = SP * Abnormal Loss / Gain OrMYV = SP (SY – AY)The difference between standard yield and actual yield is called abnormal loss or gain. If the standard yield is less thanthe actual yield, the difference is called abnormal gain, and if the standard yield is higher than the actual yield thedifference is called abnormal loss.CAUSES FOR MATERIAL USAGE VARIANCEThe causes of material usage variance are: 1. Variation is usage of materials due to inefficient or careless use or economic use of materials. 2. Change in specification or design of product. 3. Inefficient and inadequate inspection of raw materials. 4. Purchase of inferior material or change in quality of materials. 5. Rigid technical specification and strict inspection leading to more rejections which require more materials for rectifications. 6. Inefficiency in production resulting in wastages. 7. Use of substitute materials. 8. Theft or pilferage of materials. 9. Inefficient labour force leading to excessive utilization of materials. 10. Defective machines, tools, and equipments, and bad or improper maintenance leading to breakdown and more usage of materials. 11. Yield from materials in excess of or less than that provided as the standard yield. 12. Faulty materials processing. Timber for example, if not properly seasoned may be wasted while being used in subsequent processes. 13. Accounting errors, e.g. when materials returned from shop or transferred form one job to another are not properly accounted for . BSPATIL 97
  • 98. 14. Inaccurate standards 15. Change in composition of a mixture of materials for a specified output.II LABOUR COST VARIANCE (LCV) It is the difference between standard direct specified for the activity achieved and the actual direct wages paid.LCV – SLC – ALC (Standard Labour Cost – Actual Labour Cost)Labour cost variance is sub-divided into 1) Rate of pay variance and 2) Efficiency variance, which is further sub divided into a. Idle time b. Calendar variance c. Mix variance d. Yield variance 1. LABOUR RATE OF PAY VARIANCE (LRV)This is that portion of labour cost variance which is due to the difference between the standard rate of pay specified andthe actual rate paid.LRV = AT (SR - AR) = Actual time (standard rate – actual rate)CAUSES FOR LABOUR COST VARIANCEDirect labour rate variance occur due to the following: 1. Change in basic wage structure or change in piece work rate. This will give rise to the variance till such time the standards are not revised. 2. Employment of workers of grades and rates of pay different from those specified due to shortage of labour of the proper category, or through mistake, or due to the retention of surplus labour. 3. Payment of guaranteed wages to workers who are unable to earn their normal wages if such guaranteed wages form part of direct labour cost. 4. Use of a different method of payment e.g. payment of day – rates while standards are based on piece work method of remuneration. 5. Higher to lower rates paid to casual and temporary workers employed to meet seasonal demands or urgent or special work. 6. New workers not being allowed full normal wage rates. 7. Over time and night shift work in excess of or less than the standard, or where no provision has been made in their standard. This will be applicable only if overtime and shift differential payments form that laid down in the standard.2) LABOUR EFFICIENCY VARIANCE (LEV)This is also that portion of labour cost variance which is due to the difference between the standard labour hoursspecified for the outputs achieved and the actual labour hours expended. This is otherwise known as labor time variance.Labour spending variance, labour usage variance, labour quantity variance. BSPATIL 98
  • 99. LEV = SR (ST – AT)CAUSES FOR LABOUR EFFICIENCY VARIANCEThe causes giving rise to direct labour efficiency variance as follows: 1. Lack of proper supervision or stricter supervision that specified. 2. Poor working conditions 3. Delay due to, waiting for materials tools, instructions etc. if not treated as idle time. 4. Defective machine tools, and other equipments. 5. Machine break down if not booked to idle time. 6. Work on new machines requiring less tike then provided for as long as the standard is not revised. 7. Basic inefficiency of workers due to low morale, insufficient training, faulty instructions, incorrect scheduling of jobs etc. 8. Use of non standard material requiring more or less operation wages. 9. Carrying our operations not provided for and booking them as direct wages. 10. In correct standards 11. Wrong selection of workers, e.g. no employing the right type of man for doing the job. 12. Increase in labour turnover. 13. Incorrect recording of performances, i.e. time and output.LABOUR IDLE TIME VARIANCE (LITV) This is that the portion of labour cost variance which is due to the abnormal idle time of workers on account offailure of power supply, machine break – down, shortage of materials etc.LITV = IH * SR (Idle hours * standard rate per hour)LABOUR CALENDAR VARIANCE (LCV) This arises only when workers are paid for the days for which they have not worked and for which no provisionwas made while determining standards. This will happen only when some special public holidays be declared. LCV = SR * HolidaysLABOUR MIX VARIANCE (LMV) It is due to the difference in the standard output specified and actual output obtained. LYV = Standard labor cost per unit (actual output – standard output)PROBLEM 1The standard cost of the chemical mixture ‘PQ’ is as follows:40% of material P@ Rs. 400 Per k.g.60% of material Q@ Rs. 600 per kg.

Theformula for computing certain control ratios are given below.The ratio indicates how much budgeted hours have been actually utilized. If the ratio if 80% then it means that 80%budgeted hours have been utilized and the remaining 20% capacity remain idle.This ratio shows the level of activity attained during the period.This ratio shows the level of efficiency attained during a particular period. If this ratio is 130% then it shows that theefficiency is more by 30% or it has gone up by 30%.This ratio shows whether actual working days available are more or less than the budgeted working days.

Integral Accounting.Cost Leger Accounting: Under this method separate set of cost accounts have to be maintained so as to derive costdetails. It will differ from general financial accounting system adopted in the organisation. Hence, it requires twoweparate set of accounts. It can be called inter-locking system. Under cost Ledger Accounting the books are kept onlyfor the impersonal accounts. To make this system self-balancing certain set of control accounts have to be prepared. As in the case of general accounting system, transactions relating to factory operations which are ultimatelyreflected in the cost accounts are recorded in the books of original entry. Summaries from these books are journalizedand posted in the general ledger which contain control accounts and subsidiary books. The following ledger accounts inthis system.Stores Ledger:In consists of accounts of individual items of raw materials, components and consumable stores. Receipts are posted intothe stores ledger on the basis of stores received notes and issues are recorded on the basis of requisition slip. The balanceof this account shows the stock in hand.Work in Progress Ledger: It consists of accounts of each job pending on the floor. Each job accounts is debited with all direct costscharged to the job and a share of overheads. It is credited with the values transferred to finished stock ledger and whenjob is completed.Stock ledger: It contains item wise accounts in respect of finished stock intended for sale. A separate account is opened is foreach finished product or job.Cost Ledger: It is the main ledger of the costing department. It contains control accounts in respect of each ledger like storeledger, stock ledger and work in progress ledger. In addition, it contains general ledger control accounts, wages controlaccounts and overhead control accounts.Control accounts: A control account is maintained in the cost ledger so that double entry in the cost ledger may be completed andmake it self – balancing. These control accounts are nothing but total accounts or adjustment accounts, summarizingmass of information contained in the subsidiary ledgers. These control accounts are posted with the totals of items whichhave been debited or credited in detail to the accounts in the ledgers to which they relate. The balance in controlaccounts represents the total of balances in a number of accounts of similar nature maintained in that subsidiary ledger towhich the control relates.Advantages of Control accounts: Control accounts helps- to provide a check for ensuring that all expenditure are recorded.- provides a basis for reconciliation with financial accounts.- provided ready means of preparing monthly or periodical financial statements. BSPATIL 118
  • 119. Types of Control Accounts: A brief description about different control accounts are given below:Stores Ledger Control Accounts: This accounts reveals the value of stores received, issued and balances in hand. Receipts are posted from goodsreceived posted on the basis of material requisition in the credit side of the account. The balance of this accountrepresents the total balance of stock which should agree with aggregate of the balance of individual accounts in thestores ledger.Wage Control Account: This accounts records labour transactions in aggregate. It is debited with gross wages shown in wages analysissheet. It is closed by transfer of direct labour to work in progress and indirect labour to overhead.Work-in-progress Control Account: It represents the total WIP at any time. It is debited with the totals of materials, wages and overheads astransferred from the respective control accounts. The completed job will be credited in this account. Thus, this accountshows the shows the total value of unfinished jobs.Works Overhead Control Account: It deals with factory overhead expenses in aggregate. It is debited with the amount of indirect material, indirectmaterial analysis and wage analysis sheets. It is credited with the amount of overheads, recovered, as obtained from theapplied overhead analysis sheets. The balance represents under or over absorption which is transferred to overheadadjustment account.Administrative Overhead Control Account: It is debited with the administration overhead incurred and credited with the amount of administrative overheadabsorbed by finished goods. The balance represents under or over absorption of administrative overhead which istransferred to overhead adjustment account.Setting and Distribution Overhead Control Account: It is debited with the amount of selling and distribution overhead incurred and credited with overhead aabsorbedby cost of sales. Balance represents under / over absorption.Cost of Sales account: It is debited with the cost of goods sold by transfer from finished goods ledger control and also by the sellingdistribution overhead absorbed. It is closed by transferring its balance to costing profit and loss account.Costing Profit and Loss Account: It is debited with the cost of sales, abnormal losses and under absorbed overhead and credited with sales value,abnormal gain and over-absorbed overhead. Balance represents profit or loss which is transferred to cost ledger controlaccount.Cost ledger control account or General ledger Adjustments A/c: BSPATIL 119

  • 140. Lesson 11 Reconciliation of Cost and Financial AccountsWhen the Cos Ledger Accounting system is adopted in an organizations the results shown by the accounting records accounting and cost ledger accounting differ from each other. Hence, it becomes necessary to reconcile theprofit or loss shown by the two sets of records.Need for Reconciliation: 1. It is necessary to find out the reasons for the differences in the profitability of both the records. 2. Reconciliation enables to test the reliability of cost accounts. Costing figures in total should agree with the financial records.Reasons for disagreement:The difference in the profitability of cost and financial records may be due to the following reasons. 1. Items included in the financial accounts but not in cost accounts. a. Purely financial income- such as interest received on bank deposits, interest and dividend on investments, rent receivables, transfer fee received, profit on the sale of assets etc. b. Purely financial charges – such as losses due to scraping of machinery, losses on the sale of investments and assets, interest paid on the bank loans, mortgages, debentures etc., expenses of company’s transfer office, damages payable at law etc. c. Appropriation of profit – the appropriation of profit is again a matter which concerns only financial accounts. Items like payment of income tax and dividends, transfer to reserve, heavy donations, writing off of preliminary expenses, goodwill and patents appear only in profit and loss appropriation account and the costing profit and loss a/c is not affected. 2. Items included in cost accounts only: There are certain items which are included in cost accounts but not in financial accounts. They are: Charges inlieu of rent where premises are owned, interest on capital employed in production but upon which no interest is actuallypaid. 3. Under/Over absorption of overhead expenses:In cost accounts, overheads are absorbed at predetermined rates which are based on past data. In the financial accountsthe actual amount incurred is taken into account. There arise a difference between the actual expenses and thepredetermined overheads charged to product or job.If overheads are not fully recovered, which means that the amount of overheads absorbed in cost accounts is less thanthe actual amount, the shortfall is called as under recovery or under absorption. If overhead expenses recovered in costaccounts is more than that of the actually incurred, it is called over absorption. Thus, both the over and under recoverymay cause the difference in the profits of both the records. 4. Different basis of stock valuation:In cost accounts, the stock of finished goods are valued at cost by FIFO, LIFO, average rate, etc. But, in financialaccounts stocks are valued either at cost or market price, whichever is less.The valuation of work-in-progress may also lead to variation. In financial books only prime cost may be taken intoaccount for this purpose whereas in cost accounts, it may be valued at prime cost plus factory overhead. 5. Different basis of depreciation adopted:The rates and methods of charging depreciation may be different in two sets of accounts.Method of reconciliation of profits: BSPATIL 140
  • 141. The are two alternative forms of presentation of reconciliation of profits revealed by cost and financial accounts, namely Statement form Account formIn the statement form it is known as Reconciliation Statement and in the accounts form it is known as MemorandumReconciliation Account.In both forms, the profits as per one set is taken to start with and addition / adjustments are made to arrive at the profit ofanother set of books.Memorandum Reconciliation Accounts:It is an account form of reconciling the profitability of two records. The amount of profit as per cost records is creditedto the Memorandum account. The items to be deducted are debited and those to be added are credited to this amount.The balancing figure is profit/loss of financial accounts.The process of preparing reconciliation statement is worked out here in the form of problems.A proforma Memorandum Reconciliation Account is give below:Memorandum Reconciliation Account(As on ……………….)
