Platt Company produces one product, a putter called PAR-putter. Platt uses a standard cost system and determines that it should take one hour of direct labor to produce one PAR-putter. The normal production capacity for this putter is 100,000 units per year. The total budgeted overhead at normal capacity is $500,000 comprised of $200,000 of variable costs and $300,000 of fixed costs. Platt applies overhead on the basis of direct labor hours. During the current year, Platt produced 85,000 putters, worked 89,000 direct labor hours, and incurred variable overhead costs of $160,000 and fixed overhead costs of $300,000.

1. Compute the pre-determined variable overhead rate and the pre-determined fixed overhead rate.

2. Compute the applied overhead for Platt for the year.

3. Compute the total overhead variance

Total Overhead Variance

The normal production capacity for this putter is 100,000 units per year. The total budgeted overhead at normal capacity is $500,000 comprised of $200,000 of variable costs and $300,000 of fixed costs.

Platt produced 85,000 putters, worked 89,000 direct labor hours, and incurred variable overhead costs of $160,000 and fixed overhead costs of $300,000.

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

Variable= 200,000/100,000= $2 per direct labor hour

Fixed= 300,000/100,000= $3 per direct labor hour

Total= $5

Now, we can allocate overhead:

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

Allocated MOH= 89,000*5= $445,000

Finally, the total overhead variance:

TOTAL OVERHEAD VARIANCE = Actual Factory Overhead - Standard Factory Overhead

TOTAL OVERHEAD VARIANCE= 460,000 - 445,000

TOTAL OVERHEAD VARIANCE = $15,000 unfavorable
