Describe the five steps

in process costing.


Five Steps in Process CostingFive 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.



Calculate equivalent units and

understand how to use them.

Prepare journal entries for

process-costing systems.


Journal Entries ExampleJournal Entries Example

Assume that Omaha, Inc. has two processingdepartments – Assembly and Finishing.

Omaha, Inc., purchases direct materials as needed.

What is the journal entry for materials?

Work in Process, Assembly 84,050Accounts Payable Control 84,050

To record direct materials purchased and used



What is the journal entry for conversion costs?

Work in Process, Assembly 62,000Various accounts 62,000

To record Assembly Department conversion costs

What is the journal entry to transfer completedgoods from Assembly to Finishing?



Work in Process, Finishing 132,043Work in Process, Assembly 132,043

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 unitstransferred out: 31,000 units × $4.50 = $139,500

And to units in ending work in process inventory:$12,000 + $2,100 = $14,100




Costs transferred out:31,000 × ($2.40 + $2.10) $139,500

Incorporate standard costs

into a process-costing system.


Standard-Costing Methodof Process-Costing ExampleStandard-Costing Method

of Process-Costing Example

Process-costing systems using standard costsusually accumulate actual costs incurredseparately from the inventory accounts.

Assume that actual materials cost is $84,050and standard materials cost is $84,250

Current costs in Finishing Departmentare as follows:

(Transferred-in costs $30,200 + Costs transferredin from the Assembly Department $139,500)÷ 35,000 units $4.85
