The document provides an overview of cost categories for a manufacturing firm. It discusses direct materials, direct labor, and manufacturing overhead as the three main categories of manufacturing costs. It also discusses non-manufacturing or period costs like selling and administrative costs. Key issues around classifying costs as direct labor or overhead are explored. The flow of costs through raw materials, work in process, and finished goods inventory is explained. Variable and fixed costs are defined in relation to a firm's activity level.

2. OVERVIEW OF COST CATEGORIES
FOR A MANUFACTURING FIRM
 All costs incurred by the firm must be accounted for
in its financial statements
MANUFACTURING COSTS
Direct Labor (DL)
Direct Materials (DM)
Overhead (OH)
Indirect Materials
Indirect Labor
Other
NON-MANUFACTURING COSTS
Marketing or Selling Costs
Administrative Costs

3. MANUFACTURING COSTS
1. Direct Materials (DM)
 Materials that are consumed in the manufacturing
process and physically incorporated in the finished
product
 Materials whose cost is sufficiently large to justify the
record keeping expenses necessary to trace the costs to
individual products

4. 2. Direct Labor (DL)
 Labor time that is physically traceable to the
products being manufactured
 Labor time whose cost is sufficiently large to
justify the record keeping expenses necessary to
trace the costs to individual products
Example:
Direct labor for manufacturing Honda Accords
 Line workers, robot operators, painters, assembly
workers
Any labor probably not included in direct labor?
 Factory janitors, factory supervisors, factory
secretaries
MANUFACTURING COSTS

5. KEY ISSUES IN DETERMINING
DIRECT LABOR
Is idle time generally considered as direct labor? Why
or why not?
 Usually not. It is not usually due to one product,
hence it is not traceable
What are the typical fringe benefits an assembly line
worker receives?
 Health insurance, pension plan, disability insurance
Is the cost of fringe benefits for the assembly line
workers generally considered direct labor?
 Usually yes, the costs can be traced

6. KEY ISSUES IN DETERMINING
DIRECT LABOR
When an assembly line worker works overtime, he/she is
paid a regular wage plus an overtime premium. Would
most companies treat his/her regular wage as a direct
labor cost?
 Yes, the amount of time an employee works can be
traced to the products.
What about the overtime premium?
 Treated as OH, cannot be traced to a specific product.

7. 3. Manufacturing Overhead (OH)
All of costs of manufacturing excluding direct materials
and direct labor
a. Indirect Materials (IM) – Materials, used in the
manufacturing of products, which are difficult to trace
to particular products in an economical way
 Glue, nails, cleaning supplies
b. Indirect Labor (IL) – Labor, used in the
manufacturing of products, which is difficult to trace to
particular products in an economical way
 Wages for maintenance workers, factory supervisor’s
salary, idle time
MANUFACTURING COSTS

8. MANUFACTURING COSTS
C. All other types of manufacturing overhead
 Depreciation on machinery, depreciation on
factory building, factory insurance, utilities for
factory

9. NON-MANUFACTURING COSTS
1. Marketing or Selling Costs – Costs incurred
in securing orders from customers and
providing customers with the finished product
 Sales commissions, costs of shipping products
to customers, storage of finished goods,
depreciation of selling equipment (cash
register)
2. Administrative Costs – Executive,
organizational, and clerical costs that are not
related to manufacturing or marketing
 CEO’s salary, cost of controller’s office,
depreciation on administrative building.

10. CLASSIFICATION
EXERCISE
Classify the following cost items
 Depreciation on factory building
 Depreciation on office equipment
 Property tax on finished goods
warehouse
 Wages paid to forklift operator in
finished goods warehouse
 Wages paid to forklift operator in factory
 Wages paid to welders when welding
equipment is not working
 Paper used in textbook production
 Paper used in central office computer
 Wages paid to assembly line workers
 Maintenance cost for machines

11. OTHER COST CONCEPTS
Product Costs or Inventoriable Costs – costs assigned
to products that were either purchased for resale
(merchandising firm or retailer) or manufactured for sale
(manufacturing firm)
 When products are sold, product costs are recognized as
an expense (cost of goods sold or COGS). The costs of
unsold products remain in inventory and are not
expensed (i.e. not deducted from revenue in calculating
net income)
Period Costs – costs that are not product costs and that
are associated with the period in which they are incurred
 Period costs such as selling and administrative costs are
expensed (i.e. deducted from revenue in calculating net
income) in the period they are incurred

12. PRODUCT COSTS VERSUS PERIOD

Product costs include
direct materials, direct
labor, and
manufacturing
overhead.
Period costs are not
included in product
costs. They are
expensed on the
income statement.

13. QUICK CHECK 
Which of the following costs would be
considered a period rather than a product cost
in a manufacturing company?
A. Manufacturing equipment depreciation.
B. Property taxes on corporate headquarters.
C. Direct materials costs.
D. Electrical costs to light the production
facility.
E. Sales commissions.

14. COSTS RELATED TO DECISION
MAKING
Opportunity Costs - costs when taking one action
requires giving up the opportunity to earn profits from a
different action
 Nike Inc. has limited production capacity. What would
be Nike’s opportunity cost of accepting a special order
from the military for combat boots?
If Nike accepts the special order, they may not be able to
produce enough product for other sales. So, Nike would
lose the profit from the other sale.

15. COSTS RELATED TO DECISION
MAKING
Incremental Costs or Differential Costs – additional
costs incurred when choosing a certain course of action
over another (Note that incremental costs can include
opportunity costs)
 What would be Macy’s incremental costs of expanding
its fragrance department and shrinking its accessories
department?
The costs of stocking and staffing the new fragrance
area, opportunity costs of lost profit from the decrease in
sales of accessories

16. COSTS RELATED TO DECISION
MAKING
Incremental Benefits or Differential Benefits – additional
benefits reaped when choosing a certain course of action over
another
 What would be Macy’s incremental benefits of expanding its
fragrance department and shrinking its accessories
department?
Profits Macy’s expects to earn on the new fragrances it
displays/stocks
Sunk Costs – Costs that have been incurred and that are not
affected by any current/future action
 What would be considered sunk cost if Macy’s decides to expand
its fragrance department and shrink its accessories
department?
Depreciation on the building, cost of the building

17. COST FLOWS IN A
MANUFACTURING COMPANY
3. Inputs such as labor and capital equipment are
also incurred to make the product. The costs of
all the inputs used in the manufacturing
facilities are recorded in WORK IN PROCESS
INVENTORY
4. As products are finished, they are moved to
finished goods warehouse and their costs are
recorded in FINISHED GOODS (FG)
INVENTORY

• The inventory equation allows us to put together the following schedules:
Schedule of Total Manufacturing Costs
(of the period)
Schedule of Cost of Goods Manufactured

20. QUICK CHECK 
If your inventory balance at the beginning of the
month was $1,000, you bought $100 during the
month, and sold $300 during the month, what
would be the balance at the end of the month?
A. $1,000.
B. $ 800.
C. $1,200.
D. $ 200.
$1,000 + $100 = $1,100
$1,100 - $300 = $800

21. QUICK CHECK 
