Calculating and Applying Overhead

1. Calculate a Predetermined Overhead Rate based on Budget Data

2. Charge Actual Overhead to the Overhead account

3. Calculate the applied amount of Overhead $$$$, charge to WIP

4. Post applied Overhead to the Manufacturing Overhead account (above) and WIP

5. Balance in Overhead account is equal to Over/Under Applied overhead

6. Transfer ending balance in Manufacturing Overhead out, leaving a ZERO balance in Manufacturing Overhead

Manufacturing costs that cannot be traced directly to specific units produced.


Examples: Indirect labor and indirect materials and indirect manufacturing costs (rent, utilities, etc.)

Examples: Indirect labor and indirect materials and indirect manufacturing costs (rent, utilities, etc.)

Wages paid to employees who are not directly

involved in production work.

Examples: maintenance workers, janitors and

security guards.

Materials used to support the production process.

Examples: lubricants and cleaning supplies used in the automobile assembly plant.

List of costs - BUDGETED:

Rent (factory uses 75% of floorspace) $ 510,000

Utilities $ 100,000

List of costs - BUDGETED:

Budgeted Costs










Rent (factory uses 75% of floorspace) $382,500 $ 510,000

Utilities – assume 75% as well. . . . $75,000 $ 100,000

Budgeted Cost Driver

• For this problem, assume a cost driver of Direct Machine Hours:

• Budgeted Machine Hours = 302,500 hours

• What is your Predetermined Overhead Rate?

What do you do with Actual overhead?

List of costs – ACTUAL, end of year:

Utilities assume 75% as well. . . . $ 100,000

Do we use ACTUAL costs to apply Overhead to WIP?

• NO NO NO NO NO NO NO NO NO NO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Charge to Manufacturing Overhead instead – debit

How much and which accounts?

How do you apply overhead?

Apply overhead to

each job using a

predeter-mined rate.

Application of Manufacturing Overhead

Overhead applied = POHR × Actual activity

How much to Apply?

Tiger, Inc. has a predetermined overhead rate of $4.00 per machine hour. Tiger, Inc. expected to work 302,500 hours during the period but actually worked 290,000 machine hours during the period. How much should Tiger apply?

290,000 x $4 = $1,160,000

Is it Over or Under Applied?

Tiger, Inc. had actual manufacturing overhead costs of $1,210,000 and a predetermined overhead rate of $4.00 per machine hour. Tiger, Inc. expected to work 302,500 hours during the period but actually worked 290,000 machine hours during the period. Are you over or under applied? By how much?

Actual costs are Greater than Applied Rate:

Is this Over or Under Applied????

Over/Under Applied

• Actual $$$ > Applied $$$ = Under Applied or Debit Balance (unfavorable, increases COGS when you adjust)

• Actual $$$ < Applied $$$ = Over Applied or Credit Balance (favorable, decreases COGS when you adjust)
