Point out that, unlike the situation in the banquet example, overhead costs usually are not divided evenly
manufacture than others.
Assume that MTM manufacturing estimates it will spend $1 million on overhead expenses. MTM is a
highly automated manufacturing plant; therefore, the majority of its overhead expenses relate to
machinery (depreciation, repairs and maintenance, electricity used). Machine hours used would be a
The formula to calculate MTM’s predetermined overhead rate is as follows:
Estimated Total Factory Overhead Costs $1,000,000 $25/hour
Estimated Activity Base (machine hours) 40,000 hours

Ask your students to calculate the overhead that would be allocated to a product that uses 3.5 hours of
machine time. (Answer: $87.50) Remind students that overhead costs are added to the product’s materials
and labor costs.
overhead costs.
In practice, more than one factory overhead rate may be used for applying overhead. Materials-related
overhead (such as purchasing, materials receiving or inspection, and materials storage costs) could be
allocated based on the direct materials cost of a product, with the remaining overhead allocated based on
illustrated in Chapter 23.
DEMONSTRATION PROBLEM—Overapplied and Underapplied Overhead
Ask your students to calculate the amount of overhead allocated to the products of a company that has a
predetermined overhead rate of $10 per machine hour if machines were used for 10,000 hours. (Answer:
$100,000)

1. Actual overhead costs do not equal the estimated costs used to compute the predetermined overhead
rate.
2. The actual activity base (machine hours) does not equal the estimated activity base used to compute
the predetermined overhead rate.
TM 16(2) -2 shows circumstances where over- and underapplied overhead occur and how they are treated
in the accounting records.
GROUP LEARNING ACTIVITY—Journal Entries in a Job Order System
Exhibit 2 in the text summarizes the flow of costs in a job order cost system (costs move from materials
inventory to work in process to finished goods to cost of goods sold). Exhibit 9 shows the entries needed
to record manufacturing costs in T accounts. Ask your students to record the journal entries listed on TM
16(2)-3, using Exhibits 2 and 9 as a guide. The correct entries are displayed on TM 16(2)-4. You may
want to have your students post these entries to T accounts and determine account balances.
Emphasize the following points as students record their entries:
process and factory overhead.
overhead.
4. Product sales serve as the basis for transferring jobs from finished goods to cost of goods sold.
OBJECTIVE 3
SYNOPSIS
A job order cost system can also be used for a professional service business. Customers can be viewed as
jobs for which costs are accumulated. The primary product costs for services are direct labor and
through a service business is shown in Exhibit 11.

SUGGESTED APPROACH
Refer your students to Exhibit 11 in the text. While reviewing that diagram, stress the following points:
an overhead expense.
2. A cost of services account is used to record the cost of completed jobs.
GROUP LEARNING ACTIVITY—Job Order Costing in a Service Business
TM 16(2) -6 presents information about a CPA firm that does audit and tax work. Divide your class into
small groups and instruct students to determine the cost to prepare a tax return. The solution is shown on
TM 16(2) -7.
ADM OBJECTIVE
Describe the use of job order cost information for decision making.
SYNOPSIS
The job order cost system allows managers to compare the costs of similar jobs, compare overtime, and
compare actual costs to expected costs. Discrepancies can be investigated and future costs controlled.

Exhibit 12—Comparing Data from Job Cost Sheets
Make a Decision – Analyzing Job Costs
SUGGESTED APPROACH
The goal of this objective is to explore the ways in which job cost information is used in decision making.
To put your students in the role of decision maker, use the following Group Learning Activity.
GROUP LEARNING ACTIVITY—Decision Making
Handout 16(2) -1 is a brief problem asking students to interpret two job cost sheets. Ask your students to
work on this problem in groups. After providing sufficient time, ask some of the groups to report their
responses. TM 16(2) –5 provides the solution.
Chapter 16(2) Job Order Costing 333
Comparing the two job cost sheets shows that the improved price per pound of alloy does not offset the
increased costs associated with higher materials usage rates and reduced casting and machining
department efficiency. It is likely that the events are related. The lower alloy cost has probably resulted
from the purchase of sub-quality raw materials. As a result, more alloy is required per casting on Job 210
than on prior jobs. In addition, the casting and machining departments are having greater difficulty with
the castings, causing the efficiency of the departments to drop. Therefore, it appears that the new alloy
vendor is causing the company to experience more scrapped castings, which increases the materials cost
and conversion costs to produce product. Shipping costs are unaffected.
Job 210 also is allocated more overhead because it now consumes more labor hours. This allocation
