We use an allocation base because:

1. It is impossible or difficult to trace overhead costs to particular jobs.

2. Manufacturing overhead consists of many different items ranging from the grease used in machines to a production manager’s salary.

3. Many types of manufacturing overhead costs are fixed even though output fluctuates during the period.

2-19

Learning Objective

To compute predetermined

overhead rates and explain why estimated overhead costs (rather than actual overhead costs) are used in the

costing process

LO3LO3

2-20

Using a predetermined overhead rate (POHR) makes it possible to estimate total job costs sooner.

Actual overhead for the period is notknown until sometime after the period has ended.

Interpreting the Average Unit Cost

The average unit cost should not be interpretedas the costs that would actually be incurred if an

additional unit were produced.

Fixed overhead would not change if another unitwere produced, so the incremental cost of

another unit may be somewhat less than $118.

Defining Under- and Overapplied Overhead

The difference between the overhead cost applied to Work in Process and the actual overhead costs of a period is termed either underapplied or overapplied

overhead.

Underapplied overhead exists when the amount of overhead applied to jobs

during the period using the predetermined overhead rate is less than the total

amount of overhead actually incurred during the period.

Underapplied overhead exists when the amount of overhead applied to jobs

during the period using the predetermined overhead rate is less than the total
