Byrd Company produces one product, a putter called GO-Putter. Byrd uses a standard cost system and determines that it should take one hour of direct labor to produce one GO-Putter. The normal production capacity for this putter is 120,000 units per year. The total budgeted overhead at normal capacity is $1,080,000 comprised of $420,000 of variable costs and $660,000 of fixed costs. Byrd applies overhead on the basis of direct labor hours.

During the current year, Byrd produced 74,000 putters, worked 98,300 direct labor hours, and incurred variable overhead costs of $133,200 and fixed overhead costs of $612,000.

Required:
a. Compute the predetermined variable overhead rate and the predetermined fixed overhead rate.
b. Compute the applied overhead for Byrd for the year.
c. Compute the total overhead variance.

During the current year, Byrd produced 74,000 putters, worked 98,300 direct labor hours, and incurred variable overhead costs of $133,200 and fixed overhead costs of $612,000.

First, we need to calculate the estimated overhead rate:

Estimated manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Estimated manufacturing overhead rate= (420,000 + 660,000)/120,000

Estimated manufacturing overhead rate= $9 per direct labor hour

Now, we can allocate overhead:

Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base

Allocated MOH= 9*98,300= $884,700

Finally, the total overhead variance:

Overhead variance= real overhead - allocated overhead

Overhead variance= 745,200 - 884,700

Overhead variance= 139,500 favorable
