Final answer:
The variable factory overhead controllable variance is an unfavorable $241,250, calculated by subtracting the expected variable overhead cost for the actual hours of production from the actual variable overhead. The fixed factory overhead volume variance is a favorable $36,750, determined by comparing the budgeted fixed overhead to the fixed overhead for the actual volume of production.
Step-by-step explanation:
To determine the variable factory overhead controllable variance and the fixed factory overhead volume variance, we can use the following information provided:
Variable overhead cost (per hour) = Budgeted variable overhead / Budgeted hours
Variable overhead cost (per hour) = $450,000 / 60,000 hours
Variable overhead cost (per hour) = $7.50
Therefore, the variable overhead cost for the actual hours of production (64,500 hours) would be calculated as follows:
Variable overhead cost for actual hours = Variable overhead cost (per hour) × Actual hours of production
Variable overhead cost for actual hours = $7.50 × 64,500 hours
Variable overhead cost for actual hours = $483,750
The variable overhead controllable variance is the difference between the actual variable overhead costs and the amount we would expect for the actual level of activity.
Variable overhead controllable variance = Actual variable overhead - Variable overhead cost for actual hours
Variable overhead controllable variance = $725,000 - $483,750
Variable overhead controllable variance = $241,250
Since the actual cost is higher than the expected cost, the variance is unfavorable.
To find the fixed factory overhead volume variance, we look at the difference between the budgeted and actual production volume in terms of fixed overhead cost. The fixed overhead is budgeted based on the full capacity:
Fixed overhead cost per hour = Fixed overhead / Full capacity
Fixed overhead cost per hour = $262,500 / 75,000 hours
Fixed overhead cost per hour = $3.50
The fixed overhead for the actual volume would thus be:
Fixed overhead for actual volume = Fixed overhead cost per hour × Actual hours
Fixed overhead for actual volume = $3.50 × 64,500 hours
Fixed overhead for actual volume = $225,750
Fixed factory overhead volume variance = Budgeted fixed overhead - Fixed overhead for actual volume
Fixed factory overhead volume variance = $262,500 - $225,750
Fixed factory overhead volume variance = $36,750
Since the actual volume is less than budgeted volume, we have a favorable variance here.
