15-31 Three-Variance Factory Overhead Analysis (40 minutes)
1. Standard variable factory overhead rate per direct labor hour (DLH):
= Budgeted Total Variable Factory Overhead ÷ Budgeted Total Direct Labor Hours
Standard fixed factory overhead rate per DLH:
= Budgeted Total Fixed Factory Overhead ÷ Practical Capacity Labor Hours
= Practical Capacity Labor Hours ÷ Practical Capacity, in Units = 0.5 DLH/unit

In sum, the only difference between the three-way and four-way analysis is that in the
former, the spending variances for fixed and for variable overhead (reported in the
latter) are combined into a single overhead spending variance.

3. The two-variance breakdown of the total overhead variance reports two important
factors concerning overhead costs. The flexible-budget (controllable) variance
measures the difference between the actual overhead incurred and the overhead that
should have been incurred based on the actual output of the period. (This latter term

Application (60 Minutes)
1. Total Factory Overhead Application Rate:
Fixed factory overhead application rate:
Total machine hours at practical capacity:
Number of units of output at practical capacity = 40,000
Machine hours per unit × 2
Standard machine hours @ practical capacity 80,000
Fixed factory overhead rate per machine hour = budgeted
2. Total Flexible Budget (FB) for Overhead Based on Units Produced :
Total standard machine hours allowed for the units produced =
42,000 units produced × 2 machine hours per unit = 84,000 hours
Manufacturing overhead in the flexible budget for 42,000 units:
