The forecast overhead for the current year will be $11,279,512 and that total machine hours will be 160,228 hours. The actual overhead is $7,919,409 and the actual machine hours are 90,509 hours. If the Thomlin Company uses a predetermined overhead rate based on machine hours for applying overhead, as of this point in time (year to date) the overhead is over/under applied by?

To determine the overhead over/under applied, you need to compare the applied overhead with the actual overhead. Here's how you can calculate it step by step:

1. Calculate the predetermined overhead rate based on machine hours:
Predetermined overhead rate = Forecasted overhead / Forecasted machine hours
Predetermined overhead rate = $11,279,512 / 160,228 hours

2. Calculate the applied overhead:
Applied overhead = Predetermined overhead rate * Actual machine hours
Applied overhead = Predetermined overhead rate * 90,509 hours

3. Compare the applied overhead with the actual overhead:
Overhead variance = Actual overhead - Applied overhead
Over/under-applied overhead = If the value is negative, it indicates under-applied overhead. If positive, it indicates over-applied overhead.

By performing these calculations, you can determine the overhead is over/under-applied.
