Manufacturing Overhead Control

At the beginning of the year, management estimated overhead to be $4 million and the allocation base to be 200,000 machine-hours.

Compute the predetermined overhead rate for the year. How many machine-hours were actually consumed during the year?

Predetermined overhead rate

What is the amount of actual overhead cost incurred for the year?

At the end of the year, did the company overapply or underapply overhead, and by how much?
