Learning Objective 2
Describe the five steps
in process costing.

17 - 4
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.

Learning Objective 7
Incorporate standard costs
into a process-costing system.
©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster
17 - 36
Standard-Costing Method
of Process-Costing Example
Process-costing systems using standard costs
usually accumulate actual costs incurred
separately from the inventory accounts.
Assume that actual materials cost is $84,050
and standard materials cost is $84,250
What are the journal entries in the
Assembly Department?
