Forming Department:
Forming Department overhead cost = Fixed manufacturing overhead cost + (Variable overhead cost per machine-hour × Total machine-hours in the department)
= $102,400 + ($1.90 per machine-hour × 16,000 machine-hours)
= $102,400 +$30,400 = $132,800
Predetermined overhead rate = Estimated total manufacturing overhead cost ÷ Estimated total amount of the = $132,800 ÷ 16,000 machine-hours = $8.30 per machine-hour
Overhead applied to a particular job = Predetermined overhead rate × Amount of the allocation base incurred by the job = $8.30 per machine-hour × 50 machine-hours = $415
Assembly Department:
Assembly Department overhead cost = Fixed manufacturing overhead cost + (Variable overhead cost per direct labor-hour × Total direct labor-hours in the department)
= $66,000 + ($3.80 per direct labor-hour × 6,000 direct labor-hours)
= $66,000 + $22,800 = $88,800
Predetermined overhead rate = Estimated total manufacturing overhead cost ÷ Estimated total amount of the = $88,800 ÷6,000 direct labor-hours = $14.80 per direct labor-hour
Overhead applied to a particular job = Predetermined overhead rate × Amount of the allocation base incurred by the job = $14.80 per direct labor-hour × 40 direct labor-hours = $592
