part of the product and that can be
conveniently traced directly to it.
Example: A radio installed in an automobile
9. 2-8
Direct Labor
Those labor costs that can be easily
traced to individual units of product.
Example: Wages paid to automobile assembly workers

Cost Classifications for Predicting
Cost Behavior
Cost behavior refers
to how a cost will react
to changes in the level
of activity. The most
common
classifications are:
▫ Variablecosts.
▫ Fixedcosts.
▫ Mixedcosts.
15. 2-18
Variable Cost
A cost that varies, in total, in direct proportion to changes in
the level of activity. Your total texting bill may be based on
how many texts you send.
Number of Texts Sent
TotalTextingBill
16. 2-19
Variable Cost Per Unit
However, variable cost per unit is constant. The cost per
text sent may be constant at 5 cents per text message.
Number of Texts Sent

17. 2-21
Fixed Cost
A cost that remains constant, in total, regardless of
changes in the level of the activity. Your monthly
contract fee for your cell phone may be fixed for the
number of monthly minutes in your contract.

20. THE COST OF GOODS MANUFACTURED SCHEDULE
▰The cost of goods manufactured schedule is
used to calculate the cost of producing products
for a period of time. The cost of goods
manufactured amount is transferred to the
finished goods inventory account during the
period and is used in calculating cost of goods
sold on the income statement.

23. THE INVENTORY EQUATION
23
Beginning Inventory
+
Additions to Inventory
=
Ending Inventory
+
Items Removed from 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
24. 24
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?
$1,000 + $100 = $1,100
$1,100 - $300 = $800$ 800

Prime Costs and Conversion Costs

classified as follows:

EXMPLE OF OPPORTUNITY COST
You can’t choose both either to
study or watch television.
If you decide to STUDY, your
opportunity cost will be
WATCHING TELEVISION.
And if you choose WATCHING
TELEVISION, your opportunity
cost will be STUDYING.
29. SUNK COST
▰Sunk costs have already been incurred and
cannot be changed now or in the future.
These costs should be ignored when
making decisions.

30. EXAMPLE
▰ a company purchased a machine several
years ago. Due to change in fashion in several
years, the products produced by the machine
cannot be sold to customers. Therefore the
machine is now useless or obsolete. The price
originally paid to purchase the machine cannot
be recovered by any action and is therefore a
sunk cost.

32. GROSS MARGIN
▰Gross margin is a company's total sales
revenue minus its cost of goods sold (COGS),
divided by total sales revenue, expressed as a
percentage
32
33. CONTRIBUTION MARGIN
▰Contribution margin is a product's price minus
all associated variable costs, resulting in the
incremental profit earned for each unit sold.
33
34. EQUTION
▰Gross Margin
Gross margin = sale price – cost of sales
(material and labor)
▰Contribution Margin
Contribution margin = sales – variable costs
