The variable overhead efficiency variance for the month is $4,427.
The variable overhead efficiency variance shows the difference between the actual and budgeted hours worked, multiplied by the standard variable overhead rate per hour.
The formula for computing the variable overhead efficiency variance is as follows:
Variable overhead efficiency variance = Standard overhead rate x (Actual hours - Standard hours)
Standard hours per unit of output = 5.20 DLHs
Standard variable overhead rate = $11.65 per DLH
Basis of variable manufacturing overhead = direct labor-hours
Actual direct labor-hours = 8,700 DLHs
The actual total variable manufacturing overhead cost = $95,990
Actual output = 1,600 units
Budgeted standard direct labor-hours = 8,320 DLHs (5.20 x 1,600)
Variable Overhead Efficiency Variance = Standard overhead rate x (Actual hours - Standard hours)
= $11.65 x (8,700 - 8,320)
= $4,427
Thus, the variable overhead efficiency variance for the month is $4,427.
