Process costing and Job costing:
General:
Both systems assign material, labor, and overhead costs to products and they
provide a mechanism for computing unit product costs.
Both systems use the same manufacturing accounts, including Manufacturing
Overhead, Raw Materials, Work in Process, and Finished Goods.
The flow of costs through the manufacturing accounts is basically the same in both
systems.
Job costing:
1. Many different jobs are worked on during each period, with each job having
unique production requirements.
2. Costs are accumulated by individual job.
3. Unit costs are computed by job on the job cost sheet.
Process costing:
1. A single product is produced either on a continuous basis or for long periods of
time. All units of product are identical.
2. Costs are accumulated by department.
3. Unit costs are computed by department

Process Costing Computations: Three
Key Concepts – Part 3
Key Concept #2: Conversion Costs: direct
labor plus manufacturing overhead.
Direct labor costs are often small in
comparison to the other product costs in
process cost systems.

Therefore, direct labor and manufacturing
overhead are often combined into one
classification of product cost called conversion
costs. The example combines these costs:

Calculating Equivalent Units
Equivalent units = Number of partially completed
units x Percentage completion.
Equivalent units is the product of the number of
partially completed units and the percentage
completion of those units with respect to the
processing in the department.
The equivalent units is the number of complete
units that could have been obtained from the
materials and effort that went into the partially
complete units.

Calculating Equivalent Units: Examples
Assume Department A has 500 units in its ending
work in process inventory that are 60% complete
with respect to processing in the department.
These 500 partially complete units are equivalent
to 300 fully complete units (500 × 60% = 300).
Department A’s ending work in process inventory
would contain 300 equivalent units for the period.
