“Nothing in life is certain except death and taxes.” --Benjamin Franklin

LEARNING OBJECTIVES Define and illustrate a cost object Distinguish between direct costs and indirect costs Explain variable costs and fixed costs Interpret unit costs cautiously Distinguish among manufacturing companies, merchandising companies, and service-sector

companies Describe the three categories of inventories commonly found in manufacturing companies Distinguish inventoriable costs from period costs Explain why product costs are computed in different ways for different purposes Describe a framework for cost accounting and cost management

2

Cost – sacrificed resource to achieve a specific objective

Actual cost – a cost that has occurred Budgeted cost – a predicted cost Cost object – anything of interest for which

a cost is desired

Basic Cost Terminology

Introduction

Different cost concepts and terms are often used in accounting reports.

Managers who understand these concepts and terms are able to...

– best use the information provided, and– avoid misuse of that information.

Cost Object Examples at BMW

Cost Object Illustration

Product BMW X 5 sports activity vehicle

Service Dealer-support telephone hotline

Project R&D project on DVD system enhancement

Customer Herb Chambers Motors, a dealer that purchases a broad range of BMW vehicles

Activity Setting up production machines

Department Environmental, Health & Safety

7

Cost

Cost is a resource sacrificed or forgone to achieve a specific objective.

It is usually measured as the monetary amount that must be paid to acquire goods and services.

An actual cost is the cost incurred (a historical cost) as distinguished from budgeted costs.

8

Cost Object

A cost object is anything for which a separate measurement of costs is desired.– Product – Service– Project– Brand– Activity– Department

9

Cost Accumulation - Assignment

There are two basic stages of accounting for costs:

1 Cost accumulation2 Cost assignment to various

cost objects

10

Cost Accumulation - Assignment

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

11

Cost Accumulation - Assignment

Cost accumulation is the collection of cost data in some organized way by means of an accounting system.

Cost assignment is a general term that encompasses...

– tracing accumulated costs to a cost object,

– allocating accumulated costs to a cost object.

COST CONCEPTS

15

Descriptive TermsTracebility CriterionDirect Costs

Direct costs of a cost object are those that are related to a given cost object (product, department, etc.) and that can be traced to it in an economically feasible way.

Cost-Tracing describes the assignment of direct costs to the particular cost object.

16

Descriptive TermsTracebility Criterion Indirect Costs

IDC are related to the particular cost object but cannot be traced to it

in an economically feasible way.

17

Direct & Indirect Costs

Several factors affect the classification of a cost as direct or indirect:

– The materiality of the cost in question– Available information-gathering technology– Design of operations– Contractual arrangements The direct/indirect classification depends

on the choice of the cost object.

18

Descriptive TermsSeparability CriterionSeparate Cost

– which can be traced to each particular unit of batch of production

Common Cost– which are common for 2 or more

products / product lines which can be produced separately

19

Joint Cost– which are incurred in producing products

which must necessarily be produced together

By-Product Cost– is variation of Joint Cost– BP & JP cost depends upon significance

and importance

Descriptive TermsSeparability Criterion

20

Descriptive TermsComputation CriterionHistorical Cost

– is on past figuresReplacement Cost

– is present replacement valueStandard Cost or Budgeted

– is based on standards

21

Descriptive TermsFunction CriterionManufacturing Cost

– is total of consumption of raw materials, direct labour and manufacturing overheads

Selling & Distribution Cost– is cost incurred to sell & distribute

Administrative Cost– is incurred in office administration

22

Statistical TermsAverage CriterionTotal Cost

– sum total of all costsUnit Cost

– is Total Cost divided by number of units produced

– Hours worked– Packages delivered– No. of units assembled

23

Statistical Terms Grouping Criterion

Prime Cost– total of Cost of RM consumed & Direct Labour– Here Cost of RM consumed = Op. Stock RM +

Purchases RM – Closing Stock RM Conversion Cost

– total of Direct Labour and Manufacturing OH

24

Behavioural TermsVariability Criterion

Fixed Cost– which do not vary with cost object/no. of

units producedVariable Cost

– which varies with no. of units producedSemi-FixedSemi-Variable

25

Conceptual Terms

Marginal Cost– is cost of producing one more unit

Sunk Cost– is cost which cannot be recovered

even if the course of action is not madePeriod Cost

– is for a particular period

26

Cost Drivers

A cost driver is a factor, such as the level of activity or volume, that causally affects costs (over a given time span).

The cost driver of variable costs is the level of activity or volume whose change causes the (variable) costs to change proportionately.

27

28

Manufacturing

Manufacturing-sector companies purchase materials and components and convert them into finished goods.

A manufacturing company must also develop, design, market, and distribute its products.

29

Trading

Trading-sector companies purchase and then sell tangible products without changing their basic form.

30

Service Companies

– provide services or intangible products to their customers.

Labour is the most significant cost category.
