Calculate the following variances:
Variable overhead spending variance
Variable overhead efficiency variance
Fixed overhead spending variance
Fixed overhead volume variance
4. The following budgeted and actual contribution statement is for a component sold by Dark, Inc. for
June of this year:
Operating costs (all fixed)
Contribution to corporate costs and profits
Required:
Compute the sales price variance, the net sales volume variance, and the operating cost
variance for June.
Use the calculations in part a. to reconcile the budgeted and actual contribution to
corporate costs and profits.
How would you evaluate the performance of Dark, Inc.‘s manager?
ANS:
Sales price variance = (£3.70 – £4.00) 18,000 = £5,400 (U);
Variable overhead rate:
£0.75 per DLH
(£0.30 + £0.20 + £0.25)
Fixed overhead rate:
£0.15 per DLH
[(£2,000 + £10,000)/80,000 hours]
Total overhead rate:
£0.90 per DLH
(£0.75 + £0.15)
[(£22,500 + £15,000 + £21,000)-(85,000 hours £0.75)]
Variable overhead efficiency variance:
[(85,000 hours £0.75)-(82,000 hours £0.75)]
Fixed overhead spending variance:
(£12,500 – £12,000)
Fixed overhead volume variance:
[£12,000 -(82,000 hours £0.15)]
