PREDETERMINED OVERHEAD RATE FORMULA
The formula for computing a predetermined overhead rate is:
Predetermined = Estimated total manufacturing overhead cost
overhead rate Estimated total amount of the allocation base
The company in the preceding example applies overhead costs to
jobs on the basis of direct labor-hours. In other words, direct laborhours is the allocation base.
At the beginning of the year the company estimated that it would
incur $320,000 in manufacturing overhead costs and would work
40,000 direct labor-hours. The companys predetermined overhead
rate is:
$320,000
= $8 per DLH
40,000 DLHs
APPLICATION OF OVERHEAD TO JOBS
The process of assigning overhead to jobs is known as applying
overhead.
In the preceding example, Job 2B47 required 27 direct labor-hours.
Therefore, $216 of overhead cost was applied to the job as follows:
Predetermined overhead rate.......................
Direct labor-hours required for Job 2B47.......
Overhead applied to Job 2B47.......................
$8 per DLH
27 DLHs
$216
JOB-ORDER COSTING EXAMPLE
In the example appearing on the next few pages, we will trace how

h. Manufacturing overhead was applied to jobs. The companys
predetermined overhead rate was based on the following
estimates: manufacturing overhead, $315,000; direct labor
cost, $210,000.
$315,000
= 1.5 or 150%
$210,000
Since the total direct labor cost incurred was $200,000, the
total manufacturing overhead applied to work in process was
150% of this amount or $300,000. The journal entry to record
this is:
Work in Process........................................................ 300,000
Manufacturing Overhead...............................
