Work in Process Inventory: Reconcile Costs Transferred to Finished Goods
Work in process inventory contains assigned production costs for work that is not yet complete. A WIP reconciliation follows costs into production and out to finished goods when work is completed. This original exercise uses supplied job-cost totals, so you can focus on that movement without inventing a completion percentage.
Read the production cost boundaries
A fictional workshop begins the month with 1,200 in work in process. During the month it assigns 2,400 direct material, 1,800 direct labor and 900 applied manufacturing overhead. Assume those supplied assignments are valid and no other WIP movements occur.
Completed jobs transfer 4,700 of assigned cost to finished goods. That transfer amount comes from the supplied completed-job records; it is not the month’s sales revenue or cash receipts. OpenStax traces manufacturing costs through raw materials, WIP and finished goods as separate cost stages.
Complete the WIP rollforward
Current-period additions total 2,400 + 1,800 + 900 = 5,100. Add opening WIP of 1,200 to obtain 6,300 cost available in the WIP account. Subtract the completed-job transfer of 4,700 to leave ending WIP of 1,600.
Original WIP schedule
Opening WIP: 1,200.
Current manufacturing additions: 5,100.
Total cost to account for: 6,300.
Transferred to finished goods: 4,700.
Ending WIP: 1,600.
Check: 4,700 + 1,600 = 6,300.
Do not confuse completion with a sale
The 4,700 leaves WIP because the jobs are complete under the stated records. It enters finished goods in this teaching model. No sales fact has been supplied, so this exercise does not send the entire transfer straight to cost of goods sold.
Likewise, the 1,600 remaining WIP is a cost balance, not 1,600 physical units. You would need job or production information to describe the unfinished work in units. Different jobs can carry different costs, so a cost percentage alone does not establish the percentage of physical work completed.
Inspect a changed transfer without changing the input total
For a variation, suppose corrected completed-job records support a transfer of 5,000 instead of 4,700. With all other inputs fixed, ending WIP becomes 6,300 − 5,000 = 1,300. The 300 larger transfer leaves 300 less in WIP.
This variation demonstrates conservation within the stated cost flow. It does not authorize rewriting actual job records to achieve a preferred ending balance. A proposed correction needs support for which jobs were complete and what cost belonged to them.
Give a useful reconciliation explanation
Keep overhead described as the supplied allocation, rather than claiming the amount is an independently verified overhead expense. For deeper practice, review the related job-cost exercise, which builds materials, labor and applied overhead for one separate job.
Original practice response
“The WIP account has 6,300 to account for: 1,200 opening plus 5,100 additions. The supplied completed jobs transfer 4,700 to finished goods, leaving 1,600 WIP. I would trace the transfer to completed-job records and the remainder to unfinished jobs. Completion alone is not a sale.”
Questions, answered
Is the 4,700 completed-job transfer COGS?
Not from completion alone. In this model it transfers from WIP into finished goods; sale information would be needed for the next stage.
Does 1,600 WIP mean 1,600 unfinished units?
No. It is a cost balance. Physical units or completion stages require additional production records.
