Performance Evaluation Using Variances from Standard Costs LO 4 – Computing Factory Overhead Variances
LO 4 Factory Overhead Variances • Factory overhead costs are more difficult to analyze than direct labor and materials costs. This is because factory overhead costs have fixed and variable cost elements.
LO 4 Factory Overhead Flexible Budget
Budgeted Factory Overhead at Normal Capacity Normal Productive Capacity = Factory Overhead Rate $30,000 5,000 direct labor hours = Factory Overhead Rate = Factory Overhead Rate$6.00 per direct labor hour LO 4 Factory Overhead Flexible Budget
Budgeted Variable Overhead at Normal Capacity Normal Productive Capacity Variable Factory Overhead Rate = $18,000 5,000 direct labor hours Variable Factory Overhead Rate = LO 4 Factory Overhead Flexible Budget Variable Factory Overhead Rate =$3.60 per direct labor hour
Budgeted Fixed Overhead at Normal Capacity Normal Productive Capacity Fixed Factory Overhead Rate = $12,000 5,000 direct labor hours Fixed Factory Overhead Rate = LO 4 Factory Overhead Flexible Budget Fixed Factory Overhead Rate =$2.40 per direct labor hour
LO 4 Factory Overhead Variances • Variances from standard for factory overhead cost result from: • Actual variable factory overhead cost greater or less than budgeted variable factory overhead for actual production • Actual production at a level above or below 100% of normal capacity
Variable Factory Overhead Rate Standard Hours for Actual Units Produced x LO 4 Variable Factory Overhead Controllable Variance Variable Factory Overhead Controllable Variance Budgeted Variable Factory Overhead Actual Variable Factory Overhead – =
$14,400 Variable Factory Overhead Controllable Variance $10,400 – $14,400 = Variable Factory Overhead Controllable Variance – $4,000 Favorable Variance = LO 4 Variable Factory Overhead Controllable Variance Variable Factory Overhead Controllable Variance Budgeted Variable Factory Overhead Actual Variable Factory Overhead – = 4,000 direct labor hours x $3.60
LO 4 Factory Overhead Volume Variance • The fixed factory overhead volume variance is the difference between the budgeted fixed overhead at 100% of normal capacity, and the standard fixed overhead for the actual production achieved during the period.
Fixed Factory Overhead Volume Variance Standard Hours for 100% of Normal Capacity Standard Hours for Actual Units Produced Fixed Factory Overhead Rate – x = Fixed Factory Overhead Volume Variance 5,000 direct labor hours 4,000 direct labor hours = – x $2.40 Fixed Factory Overhead Volume Variance $2,400Unfavorable Variance = LO 4 Fixed Factory Overhead Volume Variance

LO 4 Fixed Factory Overhead Volume Variance • An unfavorable volume variance may be due to factors such as the following: • Failure to maintain an even flow of work • Machine breakdowns • Work stoppages caused by lack of materials or skilled labor • Lack of enough sales orders to keep the factory operating at normal capacity
