Types of Product Costing Systems
Process
Costing
Job-order
Costing

Many different products are produced each period.

Products are manufactured to order.

The unique nature of each order requires tracing or
allocating costs to each job, and maintaining cost
records for each job.

Manufacturing Overhead Application
The predetermined overhead rate (POHR) used to
apply overhead to jobs is determined before the
period begins.
POHR =
Estimated total manufacturing
overhead cost for the coming period
Estimated total units in the
allocation base for the coming period
Ideally, the allocation base
is a cost driver that causes
overhead.
3-6
Determining Predetermined Overhead Rates
Predetermined overhead rates are calculated
using a three-step process.

Cost Flows – Material Purchases
Raw material purchases are recorded in an
inventory account.

Cost Flows – Material Usage
Direct materials issued to a job increase Work in
Process and decrease Raw Materials. Indirect
materials used are charged to Manufacturing
Overhead and also decrease Raw Materials.
