How to Close Under-Applied Manufacturing Overhead to Cost of Goods Sold at Year-End
Adjusting COGS upward when actual factory overhead costs exceeded the amount applied to production during the year.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Cost of Goods Sold | Expense (+) | 1,200.00 | - |
| Manufacturing Overhead (Control) | Clearing Account | - | 1,200.00 |
💡 Accountant's Note
At year-end, if your factory cost more to run than estimated (under-applied), you must charge that extra cost to COGS to balance the books.
Practitioner & Systems Framework
💻 ERP Architecture
Manufacturing Overhead (Control) accumulates actual overhead costs incurred (utilities, depreciation, indirect labor, rent). Manufacturing Overhead (Applied) accumulates the estimated overhead charged to WIP using the predetermined rate. At year-end, compare actual (Control) to applied (Applied). If actual > applied → under-applied overhead (factories cost more than estimated) → debit COGS. If actual < applied → over-applied overhead → credit COGS (see manufacturing-over-applied-overhead-closing). For immaterial amounts, close entirely to COGS. For material amounts, prorate across WIP, Finished Goods, and COGS (see manufacturing-variance-proration-yearend).
⚠️ Audit Flags
Auditors recalculate whether the overhead variance is material enough to require proration rather than closing to COGS. Consistent under-applied overhead year after year suggests the predetermined overhead rate is systematically too low — auditors will question whether the rate needs revision. A large under-applied variance charged entirely to COGS inflates the period expense and understates inventory.
📄 Required Documentation
Manufacturing Overhead (Control) total — actual costs incurred, Manufacturing Overhead (Applied) total — amount charged to WIP, under-applied variance calculation, materiality assessment (prorate vs. COGS close), COGS adjustment entry, Overhead Control account closed to zero, and overhead rate review for next period.
