Types of Product-Costing Systems
Process
Costing
Job-Order
Costing
 Used for production of large, unique, high-cost items.
 Built to order rather than mass produced.
 Many costs can be directly traced to each job.
TWO TYPES:
Job-shop operations
Products manufactured in very low volumes or
at a time.
one
 Batch-production operations
Multiple products in batches of relatively small
quantity.

The primary document
for tracking the costs
associated with a
given job is the jobcost record.

Manufacturing Overhead Costs
Overhead is applied to jobs using a predetermined
overhead rate (POHR) based on estimates made at
the beginning of the accounting period.
1
Budgeted manufacturing overhead cost
POHR =
2 Budgeted amount of cost driver (or activity base)
Overhead applied = POHR × Actual activity
Based on estimates, and
determined before the
period begins
Actual amount of the allocation
base, such as direct labor hours,
incurred during the period

Manufacturing Overhead Costs

POHR =
Budgeted manufacturing overhead cost
Budgeted amount of cost driver (or activity base)
Overhead applied = POHR × Actual activity
Recall the Aluminum Boat example where:
Overhead applied = $30 per DLH × 600 DLH = $18,000

been discussing
in a job-order
costing system.

Document Flow Summary
Production
Order for Job
Material
Requisition
Labor Time Records
The production order for the job authorizes the start
of the production process.
The materials requisition indicates the cost of
direct material to charge to jobs and the cost of
indirect material to charge to overhead.
Employee time tickets indicate the cost of direct
labor to charge to jobs and the cost of indirect
labor to charge to overhead.

Let’s return to
AFB Company
and see what we
will do if actual

overhead are not
equal.
3-35
Overhead Application Example
Actual Overhead costs for the year: $5,050,000
Actual direct labor hours worked for the year: 170,000
Applied Overhead = POHR × Actual Direct Labor Hours
Applied Overhead = $30.00 per DLH × 170,000 DLH = $5,100,000
Applied overhead exceeds actual overhead by $50,000
This difference is called overapplied overhead.

Overapplied and Underapplied
Manufacturing Overhead
$50,000
