Learning Objective 2
Describe the five steps
in process costing.

Five Steps in Process Costing
Step 1: Summarize the flow of physical units of
output.
Step 2: Compute output in terms of equivalent units.
Step 3: Compute equivalent unit costs.
Step 4: Summarize total costs to account for.
Step 5: Assign total costs to units completed and to
units in ending work in process inventory.

departments – Assembly and Finishing.
Omaha, Inc., purchases direct materials as needed.
What is the journal entry for materials?

Learning Objective 5
Use the weighted-average
method of process costing.

Summarize and Assign Total
Costs (Steps 4 and 5)
This step distributes the department’s costs to units
transferred out: 31,000 units × $4.50 = $139,500
And to units in ending work in process inventory:
$12,000 + $2,100 = $14,100
