A company's flexible budget for the range of 35,000 units to 45,000 units of production showed variable overhead costs of $2 per unit and fixed overhead costs of $72,000. The company incurred total overhead costs of $148,800 while operating at a volume of 40,000 units. The total controllable cost variance is:

a. $6,800 favorable.

b. $6,800 unfavorable.

c. $3,200 favorable.

d. $3,200 unfavorable.

e. $10,000 favorable.

c. $3,200 favorable.

Explanation:

We know that

Total controllable cost variance = Budgeted overhead cost - actual overhead cost

where,

Budgeted overhead cost = Variable overhead + Fixed overhead

where,

Variable overhead = 40,000 units * $2 = $80,000

And, the fixed overhead = $72,000

So, the budgeted overhead = $152,000

And, the actual one is $148,800

So, the total controllable cost variance would be

= $152,000 - $148,800

= $3,200 favorable
