Cost accounting measures and reports on the costs of resources used in an organization. It provides data for both management accounting, which helps managers make internal decisions, and financial accounting. Cost accounting involves determining the costs of products, services, projects and other cost objects. It aims to provide cost data for setting prices, controlling costs, determining profitable products, and aiding decision making. Management accounting focuses on internal reporting to help managers maximize profits through planning, controlling operations and decision making.

2. Overview of Cost and Management
Accounting
Cost Accounting measures and reports
financial and nonfinancial information relating
to the cost of acquiring or consuming
resources in an organization. It provides
information for both management accounting
and financial accounting.

3. Management Accounting measures and reports
financial and nonfinancial information that helps
managers make decisions to fulfill the goals of
an organization. It focuses on internal
reporting.

4. Objectives of Cost Accounting:
 Fixing selling price,
 Making a foundation of total cost,
 Determining the profitable products,
 Controlling costs becomes easier,
 Helps in proper decision making,
 Enhances communication among
departmental managers, etc.

5. Objectives of Management Accounting:
 The primary objective of Management
Accounting is to enable management to
maximize profits or minimize losses,
 The fundamental objective of Management
Accounting is to provide relevant information
to managers for use in planning, controlling
operations and decision making.

6. Cost Accounting vs Financial Accounting
 Cost Accounting involves the preparation of a
broad range of reports that management
needs to run a business.
 Financial Accounting involves the preparation
of a standard set of reports for an outside
audience.

7. Management Accounting vs
Financial Accounting
 Management Accounting is designed to produce useful
information for a company’s internal use. Business
managers collect information that encourages strategic
planning, helps them se realistic goals, and encourages
an efficient directing of company resources,
 Financial Accounting has some internal use as well, but
it is much more concerned with informing those outside
of a company. Financial statements are designed to
disclose the firm’s business performance and financial
health.

8. Introduction
 Accounting systems provide information useful to
users in the form of Financial Accounting and
Management Accounting reports
 Cost Accounting is a bridge between them
 Cost Accounting is a method for determining cost of a
product, service, project or thing.
 Aids financial accounting by providing product cost
information to be reported in financial statements
 Aids management accounting by providing cost
information to managers for performing their tasks-
planning and control.

9. Basic Cost Terminology
 Cost – sacrificed resource to achieve a specific objective
 Actual cost – a cost that has occurred
 Budgeted cost – a predicted cost
 Expense – a cost that has given a benefit and now expired.
 Loss – unintentionally incurred in the context of business
operation
 Cost object – anything of interest for which a separate cost
is desired.
 It may be a product, service, project, department, division, branch,
customer, etc

11. Basic Cost Terminology
 Cost accumulation – a collection of cost data in an
organized manner
 Cost assignment – a general term that includes
gathering accumulated costs to a cost object. This
includes:
 Tracing accumulated costs with a direct relationship to
the cost object and
 Allocating accumulated costs with an indirect
relationship to a cost object
12/27/2022

12. Direct & Indirect Costs
 Direct costs – can be conveniently and economically
traced (tracked) to a cost object.
 Used by a single cost object
 Avoided if the cost object is avoided
 Direct materials- cost of materials specifically used in manufacturing a
product. E.g. Lumber & metal frame cost in chair, cost of cottons in textile
factory, etc
 Direct labor-specific labor cost that can be identified with work involved in
production. E.g. salary, wages and fringe benefits for direct factory workers
12/27/2022

13. Direct & Indirect Costs
 Indirect costs – cannot be conveniently or
economically traced (tracked) to a cost object. Instead
of being traced, these costs are allocated to a cost
object in a rational and systematic manner
 Can be classified in to
 Those indirectly related to cost objects (common costs)
 E.g. salary of supervisors managing production, electricity,
rent, salary of janitors, property taxes, etc
 Those directly related to cost object but is not
economically feasible to trace them.
 E.g. glues, nails, etc

15. Factors Affecting Direct / Indirect
Cost Classification
 Cost Materiality
 Availability of information-gathering technology
 Operational Design
12/27/2022

16. Cost Behavior
 Variable costs – change in total in proportion to
changes in the related level of activity or volume.
 DM, DL, IM, IL (in some instances), some selling & adm. exp
 Fixed costs – remain unchanged in total regardless of
changes in the related level of activity or volume
 Salary of plant supervisor, depreciation exp., property taxes, etc
 Semi-variable (mixed) costs- have both variable & fixed
cost portion. E.g. telephone and electricity costs
 Semi-fixed (step-function) costs-fixed over some activity
ranges & change dramatically as level of activity moves
from one range to another.
 Costs are fixed or variable only with respect to a
specific activity or a given time period
12/27/2022

17. Cost Behavior, continued
 Variable costs – are constant on a per-unit basis. If a
product takes 5 pounds of materials each, it stays the
same per unit regardless of one, ten or a thousand
units are produced
 Fixed costs – change inversely with the level of
production on per unit basis. As more units are
produced, the same fixed cost is spread over more
and more units, reducing the cost per unit

20. Other Cost Concepts
 Cost Driver – a variable that causally affects costs over
a given time span. E.g. labor hours for labor cost, Kilowatt hours
for energy cost, no. of advertisements for adv. Expense, etc
 Fixed costs have no cost driver in the short run
 Cost driver is a cost allocation base for indirect costs
 Relevant Range – the band of normal activity level (or
volume) in which there is a specific relationship
between the level of activity (or volume) and a given
cost
 For example, fixed costs are considered fixed only within
the relevant range.

22. A Cost Caveat
 Unit costs should be used cautiously. Since unit costs
change with a different level of output or volume, it
may be more prudent to base decisions on a total
dollar basis.
 Unit costs that include fixed costs should always
reference a given level of output or activity
 Unit Costs are also called Average Costs
12/27/2022

23. Multiple Classification of Costs
 Costs may be classified as:
 Direct / Indirect, and
 Variable / Fixed
 These multiple classifications give rise to important
cost combinations:
 Direct & Variable
 Direct & Fixed
 Indirect & Variable
 Indirect & Fixed

25. Other Cost Types
 Differential & Marginal costs
 Controllable and Noncontrollable costs
 Opportunity costs
 Sunk costs
 Relevant and Irrelevant costs

26. Different Types of Firms
 Manufacturing-sector companies – create and sell
their own products
 Merchandising-sector companies – product resellers
 Service-sector companies – provide services
(intangible products)
12/27/2022

27. Types of Manufacturing Inventories
 Direct Materials – resources in-stock and available for
use
 Work-in-Process (or progress) – products started but
not yet completed. Often abbreviated as WIP
 Finished Goods – products completed and ready for
sale
12/27/2022

28. Types of Product Costs
 Also known as Inventoriable Costs
 Direct Materials
 Direct Labor
 Indirect Manufacturing – factory costs that are not
traceable to the product. Other common names for this
type of cost include Manufacturing Overhead costs or
Factory Overhead costs.
12/27/2022

29. Accounting Distinction Between
Costs
 Inventoriable costs – product manufacturing costs.
These costs are capitalized as assets (inventory) until
they are sold and transferred to Cost of Goods Sold.
 Period costs – have no future value and are expensed as
incurred.
12/27/2022

30. Cost Flows
 The Cost of Goods Manufactured and the Cost of
Goods Sold section of the Income Statement are
accounting representations of the actual flow of costs
through a production system.
 Note the importance of inventory accounts in the
following accounting reports, and in the cost flow chart

Direct labor used 100,000
Required
Assume full absorption costing is used prepare an Income Statement and separate
Schedule of Cost of Goods Manufactured for the HH Company for February.

35. Other Cost Considerations
 Prime cost is a term referring to all direct
manufacturing costs (labor and materials)
 Conversion cost is a term referring to direct labor and
factory overhead costs, collectively
 Overtime labor costs are considered part of overhead
due to the inability to precisely know the true cause of
these costs
12/27/2022

36. Different Definitions of Costs
for Different Applications
 Pricing and product-mix decisions – may use a “super”
cost approach (comprehensive)
 Contracting with government agencies – very specific
definitions of cost for “cost plus profit” contracts
 Preparing external-use financial statements – GAAP-
driven product costs only

38. Three Common Features of
Cost Accounting & Cost Management
1. Calculating the cost of products, services, and other
cost objects
2. Obtaining information for planning & control, and
performance evaluation
3. Analyzing the relevant information for making
decisions
