Basic Cost Terminology

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 Cost Accumulation – a collection of cost data

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
Слайд 4

Direct and Indirect Costs Direct Costs – can be conveniently and

Direct and Indirect Costs

Direct Costs – can be conveniently and economically

traced (tracked) to a cost object
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

Cost Behavior Variable Costs – changes in total in proportion to

Cost Behavior

Variable Costs – changes in total in proportion to changes

in the related level of activity or volume
Fixed Costs – remain unchanged in total regardless of changes in the related level of activity or volume
Costs are fixed or variable only with respect to a specific activity or a given time period
Слайд 8

Cost Behavior, continued Variable costs – are constant on a per-unit

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 whether one, ten, or a thousand units are produced
Fixed costs – change inversely with the level of production. As more units are produced, the same fixed cost is spread over more and more units, reducing the cost per unit

Unchanged in relation to output

Change inversely with output
More output = lower cost per unit

Other Cost Concepts Cost Driver – a variable that causally affects

Other Cost Concepts

Cost Driver – a variable that causally affects costs

over a given time span
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 fixed only within the relevant range.

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.

Different Types of Firms

Manufacturing-sector companies – create and sell their own

products
Merchandising-sector companies – product resellers
Service-sector companies

Types of Inventories Direct Materials – resources instock and available for

Types of Inventories

Direct Materials – resources instock 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

Types of Product Costs Direct Materials Direct Labor Indirect Manufacturing –

Types of Product Costs

Direct Materials
Direct Labor
Indirect Manufacturing – factory costs that

are not traceable to the product. Also known as Manufacturing Overhead costs or Factory Overhead costs

Distinctions Between Costs Inventoriable Costs – product manufacturing costs. These costs

Distinctions 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
Слайд 16

Cost Flows The Cost of Goods Manufactured and the Cost of

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
Слайд 17

Cost of Goods Manufactured Calculates the cost of Direct Materials Used

Cost of Goods Manufactured

Calculates the cost of Direct Materials Used

Accumulates the

three product costs for the current period

Adjusts the current period manufacturing costs to account for units actually completed

Other Cost Considerations Prime cost is a term referring to all

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

Different Definitions of Cost for Different Applications Pricing and product-mix decisions

Different Definitions of Cost 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
