Factory Overhead Cost Variances The following data relate to factory overhead cost for the production of 4,000 computers: Actual: Variable factory overhead Fixed factory overhead. Standard: 4,000 hrs. at $34 $115,400 25,500 136,000 If productive capacity of 100% was 6,000 hours and the total factory overhead cost budgeted at the level of 4,000 standard hours was $144,500, determine the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance. The fixed factory overhead rate was $4.25 per hour. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.. Variance Amount Favorable/Unfavorable Variable factory overhead controllable variance Fixed factory overhead volume variance Total factory overhead cost variance
