Calculating factory overhead: two variances
Missoula Manufacturing Company normally produces 10,000
units of product X each month. Each unit requires 2 hours of
direct labor, and factory overhead is applied on a direct labor
hour basis. Fixed costs and variable costs in factory overhead at
the normal capacity are $5 and $3 per unit, respectively. Cost and
production data for May follow:
Production for the month . . . . . . . . . . . . ............ 9,000 units
Direct labor hours used . . . . . . . . . . . . . . . . . . . . . . . . . . 18,500 hours
Factory overhead incurred for:
Variable costs ................................. $28,500
Fixed costs ................................... $52,000
a. Calculate the controllable variance.
b. Calculate the volume variance.
c. Was the total factory overhead under- or overapplied? By
what amount?
