Pioneered the “direct business model “ of selling computers
  • Many orders are taken over the internet
  • Need to know product cost
  • Chapter focuses on applying overhead to products
learning objective 1
Learning Objective 1
  • Compute budgeted
  • factory-overhead rates
  • and apply factory
  • overhead to production.
accounting for factory overhead
Accounting for Factory Overhead

Methods for assigning overhead costs

to the products is an important part of

accurately measuring product costs.

budgeted overhead application rates
Budgeted OverheadApplication Rates


1. Select one or more cost drivers.

2. Prepare a factory overhead budget.

3. Compute the factory overhead rate.

4. Obtain actual cost-driver data.

5. Apply the budgeted overhead

to the products.

6. Account for any differences between the

amount of actual and applied overhead.

budgeted overhead application rates6
Budgeted OverheadApplication Rates

Budgeted overhead application rate

= Total budgeted factory overhead

÷ Total budgeted amount of cost driver

illustration of overhead application
Illustration of Overhead Application

Enriquez Machine Parts Company’s

budgeted manufacturing overhead for

the machining department is $277,800.

Budgeted machine hours are 69,450.

What is the rate?

$277,800 ÷ 69,450 = $4 per machine hour

illustration of overhead application8
Illustration of Overhead Application

Suppose that at the end of the year Enriquez

had used 70,000 hours in Machining.

How much overhead was applied to Machining?

70,000 × $4 = $280,000

objective 2
Objective 2
  • Determine and use appropriate
  • cost drivers for overhead
  • application.
choice of cost drivers
Choice of Cost Drivers

No one cost driver is right for all situations.

The accountant’s goal is to find the

driver that best links cause and effect.

choice of cost drivers11
Choice of Cost Drivers

A separate cost pool should

be identified for each driver.

  • Identify the meaning and
  • purpose of normalized
  • overhead rates.
normalized overhead rates
Normalized Overhead Rates

“Normal” product costs include

an average or normalized

chunk of overhead.

Actual direct material

+ Actual direct labor

+ Normal applied overhead

= Cost of manufactured product

disposing of underapplied or overapplied overhead
Disposing of Underapplied or Overapplied Overhead

Suppose that Enriquez applied

$375,000 to its products.

Also, suppose that Enriquez incurred

$392,000 of actual manufacturing

overhead during the year.

disposing of underapplied or overapplied overhead15
Disposing of Underapplied or Overapplied Overhead

How much was underapplied?

$392,000 actual – $375,000 applied = $17,000

Prorating Among Inventories

Prorate $17,000 of underapplied

overhead assuming the following

ending account balances:

Work-in-Process Inventory $ 155,000

Finished Goods Inventory 32,000

Cost of Goods Sold 2,480,000

Total $2,667,000

prorating among inventories18
Prorating Among Inventories

$17,000 × 155/2,667

= 988 to Work-in-Process Inventory

$17,000 × 32/2,667

= $204 to Finished Goods Inventory

$17,000 × 2,480/2,667

= $15,808 to Cost of Goods Sold

the use of variable and fixed application rates
The Use of Variable and Fixed Application Rates

The presence of fixed costs is a

major reason of costing difficulties.

Some companies distinguish between

variable overhead and fixed

overhead for product costing.

variable versus absorption costing
Variable VersusAbsorption Costing

This section compares two

methods of product costing.





variable versus absorption costing21
Variable VersusAbsorption Costing

Variable costing excludes fixed

manufacturing overhead

from inventoriable costs.

Absorption costing treats fixed

manufacturing overhead

as inventoriable costs.

Facts and Illustration

The annual budget for fixed manufacturing

overhead is $1,500,000

Budgeted production is 15,000 computers.

Sales price = $500 per unit

$20 per computer is variable overhead.

Fixed S&A expenses = $650,000

Sales commissions = 5% of dollar sales

  • Compute the production-
  • volume variance and show
  • how it should appear in
  • the income statement.
production volume variance
Production-Volume Variance

Applied fixed overhead – Budgeted fixed overhead

= (Actual volume × Fixed-overhead rate) –

(Expected volume × Fixed-overhead rate)

In practice, the production-volume variance

is usually called simply the volume variance.

Production-Volume Variance

A production-volume variance arises when

the actual production volume achieved

does not coincide with the expected

volume of production used as a denominator

for computing the fixed-overhead rate.

There is no production-volume

variance for variable overhead.

reconciliation of variable costing and absorption costing
Reconciliation of Variable Costing and Absorption Costing

Absorption unit cost is higher.

Output-level (production-volume)

variance exists only under

absorption costing.

reconciliation of variable costing and absorption costing37
Reconciliation of Variable Costing and Absorption Costing

Under absorption costing, fixed overhead

appears in the cost of goods sold and

also in the production-volume variance.

Under variable costing, fixed

overhead is a period cost.

reconciliation of variable costing and absorption costing38
Reconciliation of Variable Costing and Absorption Costing

The difference between income reported

under these two methods is entirely due to

the treatment of fixed manufacturing costs.

Under absorption costing, these costs are

treated as assets (inventory) until the

associated goods are sold.

  • Explain how a company might
  • prefer to use a variable-
  • costing approach.
why use variable costing
Why Use Variable Costing?

One reason is that absorption-costing

income is affected by production

volume while variable-costing

income is not.

Another reason is based on which

system the company believes

gives a better signal about


flexible budget variances
Flexible-Budget Variances

All variances other than the

production-volume variance are

essentially flexible-budget variances.

flexible budget variances42
Flexible-Budget Variances

Flexible-budget variances measure

components of the differences

between actual amounts and

the flexible-budget amounts

for the output achieved.

flexible budget variances43
Flexible-Budget Variances

Flexible budgets are primarily

designed to assist planning and

control rather than product costing.

effects of sales and production on reported income
Effects of Sales and Productionon Reported Income

Production > Sales

Variable costing income is lower

than absorption income.

Production < Sales

Variable costing income is higher

than absorption income.
