Cost Management System
A cost-management system (CMS) is a
collection of tools and techniques that
identifies how management’s decisions
affect costs.

What is Cost Accounting?
Cost accounting is that part of the
accounting system that measures costs
for the purposes of management decision
making and financial reporting.

Cost
A cost may be defined as a sacrifice or
giving up of resources for a particular
purpose.
 Costs are frequently measured by the
monetary units that must be paid for
goods and services.


Cost Objective
What is a cost object or cost objective?
It is anything for which a separate measurement
of costs is desired.

4-9
Learning Objective 3
Distinguish among direct,
indirect, and unallocated costs.

4 - 10
Direct Costs
What are direct costs?
Direct costs can be identified specifically
and exclusively with a given cost
objective in an economically
feasible way.
©2002 Prentice Hall Business Publishing, Introduction to Management Accounting 12/e, Horngren/Sundem/Stratton
4 - 11
Indirect Costs
What are indirect costs?
Indirect costs cannot be identified
specifically and exclusively with a
given cost objective in an economically
feasible way.
©2002 Prentice Hall Business Publishing, Introduction to Management Accounting 12/e, Horngren/Sundem/Stratton
4 - 12
What Distinguishes
Direct and Indirect Costs?
Managers prefer to classify costs as direct
rather than indirect whenever it is
“economically feasible” or “cost effective.”
 Other factors also influence whether a cost
is considered direct or indirect.
 The key is the particular cost objective.


Categories of
Manufacturing Costs
Any raw material, labor, or other input
used by any organization could,
in theory, be identified as a
direct or indirect cost
depending on the
cost objective.

All costs which are eventually allocated
to products are classified as either…
direct materials,
direct labor, or
indirect manufacturing.

4 - 15
Direct Material Costs...
–
include the acquisition costs of all materials
that are physically identified as a part of the
manufactured goods and that may be traced
to the manufactured goods in an
economically feasible way.
©2002 Prentice Hall Business Publishing, Introduction to Management Accounting 12/e, Horngren/Sundem/Stratton
4 - 16
Direct Labor Costs...
–
include the wages of all labor that can be
traced specifically and exclusively to the
manufactured goods in an economically
feasible way.
©2002 Prentice Hall Business Publishing, Introduction to Management Accounting 12/e, Horngren/Sundem/Stratton
4 - 17
Indirect Manufacturing Costs...
–
or factory overhead, include all costs
associated with the manufacturing process
that cannot be traced to the manufactured
goods in an economically feasible way.
©2002 Prentice Hall Business Publishing, Introduction to Management Accounting 12/e, Horngren/Sundem/Stratton
4 - 18
Product Costs...
are costs identified with goods produced
or purchased for resale.
 Product costs are initially identified as part
of the inventory on hand.
 These costs, inventoriable costs, become
expenses (in the form of cost of goods sold)
only when the inventory is sold.

Period Costs...
–
are costs that are deducted as expenses
during the current period without going
through an inventory stage.

Period or Product Costs
In merchandising accounting, insurance,
depreciation, and wages are period costs
(expenses of the current period).
 In manufacturing accounting, many of these
items are related to production activities and
thus, as indirect manufacturing, are product
costs.


Period Costs – Merchandising
and Manufacturing

In both merchandising and manufacturing
accounting, selling and general
administrative costs are period costs.

Learning Objective 4

statements of merchandisers
and manufacturers differ
because of the types of goods
they sell.

Costs and Income Statements

On income statements, the detailed
reporting of selling and administrative
expenses is typically the same for
manufacturing and merchandising
organizations, but the cost of goods sold
is different.

Cost of Goods Sold
for a Manufacturer


The manufacturer’s cost of goods produced
and then sold is usually composed of the
three major categories of cost:
Direct materials
Direct labor
Indirect manufacturing

Cost of Goods Sold
for a Retailer or Wholesaler

The merchandiser’s cost of goods sold is
usually composed of the purchase cost of
items, including freight-in, that are acquired
and then resold.

Activity-Based Costing
Understanding the relationships
among activities, resources,
costs, and cost drivers is the key
to understanding ABC and how
ABC facilitates managers’
understanding of operations.

Activity-Based Costing
Example of Activities and Cost Drivers:
Activities:
Cost Drivers:
Account billing
No. of lines
Bill verification
No. of accounts
Account iniquity
No. of labor hours
Correspondence
No. of letters

Identify the steps involved in the
design and implementation
of an activity-based
costing system.

Designing and Implementing an
Activity-Based Costing System
Step 1
Step 2
Determine cost of
activities, resources,
and related cost
drivers.
Develop a process-based
map representing the flow
of activities, resources, and
their interrelationships.

Designing and Implementing an
Activity-Based Costing System
Step 3
Collect relevant data concerning costs
and the physical flow of the cost-driver
units among resources and activities.

Designing and Implementing an
Activity-Based Costing System
Step 4
Calculate and interpret the new
activity-based information.
Using an activity-based costing system to
improve the operations of an organization
is activity-based management (ABM).

Activity-Based Management
Activity-based management aims
to improve the value received by
customers and to improve profits
by identifying opportunities for
improvements in strategy and
operations.

4 - 38
Activity-Based Management
A value-added cost is the cost of an activity
that cannot be eliminated without affecting
a product’s value to the customer.
 In contrast, non-value-added costs are costs
that can be eliminated without affecting a
product’s value to the customer.
