The Meaning of Cost
Product Costs
• Related to the
purchase or
manufacture of
goods for resale.
• Assigned to
inventory and cost
of goods sold.
The use of
valuable
resources, in
order to achieve a
stated purpose. In
accounting, cost
is reported in
monetary terms.
Period Costs
• Related to selling
and administrative
operations.
• Recognized as
expenses in the
same time period.

Comparing Service, Retail and
Manufacturing Companies
Service firms . . .
 Provide a service that is
consumed when produced.
 Have no inventories.
Retailers . . .
 Buy finished goods.
 Sell finished goods.

Manufacturing Companies
The 3 major categories of
manufacturing costs:
Direct Materials
Raw materials,
components, and
other parts that
can be traced to a
specific product.
Direct Labor
Payments and
benefits for those
employees who
convert direct
materials into
finished product.

Production Costs in the Service
Sector



A service provider cannot
“inventory” its services.
The costs of providing the
service can be identified and
measured, just as occurs in
manufacturing industries.
Managing and tracking the
costs associated with valuechain activities can point to
opportunities for improvement.
2-27
Cost Drivers
An “activity” is any
discrete task that an
organization
undertakes to make
or deliver a good or
service.
A “cost driver” is
some characteristic
of the activity that
causes costs to be
incurred.
Number of
computers made by
Dell in a day
Number of
flights by Southwest
Airlines in a given market
2-28
Learning Objective 4
2-29
Cost Behavior
Cost behavior means how
a cost will react to
changes in the level of
business activity.

Total variable costs
change when activity
level changes.

Total fixed costs remain
unchanged when activity
level changes.
2-30
Total Variable Cost Example
Total Long Distance
Telephone Bill
Your total long distance telephone bill
is based on how many minutes you talk.
Minutes Talked
2-31
Variable Cost Per Unit Example
Per Minute
Telephone Charge
The cost per long distance minute talked is
constant. For example, 5 cents per minute.
Minutes Talked
2-32
Total Fixed Cost Example
Monthly Basic
Telephone Bill
Your monthly basic telephone bill
probably does not change when you
make more local calls.
Number of Local Calls
2-33
Fixed Cost Per Unit Example
Monthly Basic Telephone
Bill per Local Call
The average cost per local call
decreases as more local calls are made.
Number of Local Calls
2-34
Cost Behavior Summary
Summary of Variable and Fixed Cost Behavior
Cost
In Total
Per Unit
Variable
Changes proportionately with
changes in activity within the
relevant range.
Remains constant for each
additional unit as long as activity
is in the relevant range.
Fixed
Remains the same even when
activity changes within the
relevant range.
The per unit amount changes
each time the level of activity
changes due to the fixed nature
of the related costs.
2-35
Cost Hierarchy
Unit-level
Costs
Directly traceable
to the decision to
produce the level
of output
Costs that are incurred for every unit of product
manufactured or service produced.
Includes direct material, direct labor, utilities to
run equipment, other overhead directly related to
the production process.
All unit level costs are variable, but not
all variable costs are unit level costs.
2-36
Cost Hierarchy
Batch-level
Costs
Costs that are incurred for batch of product
manufactured or service produced.
Includes setup costs, material-handling costs
related to delivering raw material to the
production line, etc.
2-37
Cost Hierarchy
Product-level
Costs
Costs that are incurred for each line of product
or service.
Includes design costs for product lines and
marketing costs for each product line.
2-38
Cost Hierarchy
Facility-level
Costs
Costs that are incurred to maintain the
organization’s overall facility and infrastructure.
Includes production manager’s salary, plant
depreciation, and insurance on the facility and
equipment.
2-39
Learning Objective 5
2-40
Committed and Discretionary Costs
Committed
Discretionary
Long-term obligations,
difficult to change in
the short term.
Easier to alter in the
short term by current
managerial decisions.
Rental and/or
Lease Financing
of Buildings and
equipment
Advertising and
Research and
Development
2-41
Opportunity Costs
The potential benefit that is given up when
one alternative is selected over another.
If you were not attending
college, you could be
earning $20,000 per year.
Your opportunity cost of
attending college for
one year is $20,000.
2-42
Sunk Costs
Past payments for resources that cannot be changed
by any current or future decision.
Sunk costs should not be considered in decisions.
Example: You bought an automobile for $12,000 two
years ago. Whatever you do with the automobile in
the future, you cannot nullify the original transaction. If
it has a trade-in value, that value would become an
opportunity cost in your future decisions.
2-43
Traceability of Resources
Direct Costs
Indirect Costs

Costs that can be
traced easily and
conveniently to a
product or department.

Costs that need to be
allocated, before they
can be assigned to a
product or department.

Example: Cost of paint in
the paint department of
an automobile assembly
plant.

Example: Cost of
national advertising for
an airline is indirect to a
given flight or route.

Howell, Inc. produces a single product with a sales price
of $40 and the following cost information:

Cost of goods sold decreases because production
exceeds sales, leaving a portion of fixed
manufacturing costs in inventory.

Throughput Costing
Unit-level
spending for
direct costs
Product
cost
Indirect, past
or committed
costs
Unit-level costs are incurred every time a unit of
product is manufactured and will not be incurred
again until the next unit is manufactured.

Throughput Costing
Example
In an automated process direct material may be
the only unit-level cost and so is the only product cost.
All other manufacturing costs are expensed as period costs.
Incentive to
overproduce
is reduced
Average unit cost does
not vary with changes
in production levels.

Intentional Overproduction of Inventory



Absorption costing: Excess inventory would
include more fixed production costs, so that gross
income for the period would be artificially higher.
An unethical manager would have an incentive to
“produce for inventory” at the end of a period, in
order to obtain a better looking bottom line.
Throughput costing: No such incentive would
exist, since fixed production costs would be
charged against operating income for the period.
