The following data relate to factory overhead cost for the production of 10,000 computers: Actual: Variable factory overhead $262,000 Fixed factory overhead 90,000 Standard: 14,000 hrs. at $25 350,000 If productive capacity of 100% was 15,000 hours and the total factory overhead cost budgeted at the level of 14,000 standard hours was $356,000, determine the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance. The fixed factory overhead rate was $6.00 per hour. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

Calculation of variable overhead controllable variance

Standard hours allowed for 10,000 computers = 14,000 hours

Budgeted variable expense = Standard hours allowed * variable overhead rate

= 14,000 * ($25 - $6)

= $266,000

Variable overhead controllable variance = Actual variable overhead expense - Budgeted variable overhead expense

= $262,000 - $266,000

=$4,000 (Unfavorable)

Calculation of fixed overhead volume variance:

Applied overhead = Number of computers produced * Fixed overhead rate

= 10,000 * $6.00

= $60,000

Budgeted fixed overhead = $90,000

Fixed overhead volume variance = Budgeted fixed overhead - Applied fixed overhead

 = $90,000 - $60,000

= $30,000 (Favorable)

Calculation of Total factory overhead volume variance:

Total factory overhead cost variance = Variable overhead controllable variance + Fixed overhead volume variance

= - $4,000 + $30,000

= $26,000 (Favorable)
