Predetermined Overhead Rates Predetermined overhead rate = Estimated total manufacturing overhead costEstimated total amount of the allocation base $360,00090,000 Machine-hours Predetermined overhead rate = Predetermined overhead rate = $4.00 per machine-hour
Predetermined Overhead Rates Variable component of thepredetermined overhead rate = Variable component of thepredetermined overhead rate = $1.00 per machine-hour $90,00090,000 Machine-hours $270,00090,000 Machine-hours Fixed component of thepredetermined overhead rate = Fixed component of thepredetermined overhead rate = $3.00 per machine-hour
