(Spending variance)
$40,000 U
(Volume variance)
$68,600 U
(Total fixed overhead variance)
Interpretation
The $28,600 unfavorable spending variance means actual cost of fixed
overhead is more than budgeted.
The $40,000 unfavorable volume variance is the result of the company actually
operating at 70% capacity rather than the budgeted 75% capacity. Not all of
the budgeted fixed overhead is applied to production because actual volume
fell below budgeted volume.
3. The controllable variance is computed as:
Variable overhead spending variance ……………………………..
$15,000 U
Variable overhead efficiency variance ……………………………..
40,000 F
Fixed overhead spending variance …………………………..……..
28,600 U
Controllable variance……………………………………………………...
$ 3,600 U
The controllable variance refers to activities that are considered within
management’s control. The unfavorable controllable variance of $3,600
indicates that overall, management performed relatively poorly in controlling
overhead costs.

Overhead controllable variance ……………………………………………………….
$ 14,375 U
* Alternative solution approach: We know the overhead controllable variance is equal to the
total overhead variance less the overhead volume variance. Then, using the results from
parts 1 and 2, we can compute the overhead controllable variance as
Overhead controllable variance = $20,625 U – $6,250 U = $14,375 U
EX
Exercise 21-21 (25 minutes)
Preliminary calculations:
Variable overhead rate per DL hour = $48,000/24,000 = $2 per hour
Fixed overhead rate per DL hour = $44,400/24,000 = $1.85 per hour
