Answer: The correct formula to compute the predetermined overhead rate is Predetermined overhead rate = Estimated total manufacturing overhead costs ÷ Estimated total units in the allocation base.
Explanation:
For example:
Estimated total manufacturing overhead costs = 5000000
Estimated total units in the allocation base = 60000
Total real units produced = 30000
So, Predetermined overhead rate = 5000000 ÷ 60000 = 83.33
Real overhead cost = Predetermined overhead rate × Total real units produced.
So Real overhead cost = 83.33 × 30000 = 2499900.
