First of all, the predetermined overhead rate will be calculated.
Predetermined overhead rate = Estimated Overheads ÷ Estimated direct labor hours
Estimated overheads = $ 239,700
Estimated direct labor hours = 4,700 hours
Predetermined overhead rate = $ 239,700 ÷ 4,700 hours = $ 51 per direct labor hour
Actual hours worked = 4,600 hours
Applied overheads = Actual hours worked × Predetermined overhead rate
Applied overheads = 4,600 hour × $ 51 per direct labor hour = $ 234,600
