Requirements
1. Compute the predetermined manufacturing overhead rate.
2. Post actual and allocated manufacturing overhead to the Manufacturing overhead T-account.
3. Close the under- or overallocated overhead to Cost of goods sold.
4. The predetermined manufacturing overhead rate usually turns out to be inaccurate. Why don't accountants just use the actual manufacturing overhead rate?
