Answer to Question 2
1. In the columnar presentation of variable overhead variance analysis, all numbers shown in bold are calculated from the given information, in the order (a)(e).
VARIABLE MANUFACTURING OVERHEAD
Flexible Budget:
Budgeted Input Qty.
Actual Costs Incurred Actual Input Qty.
Budgeted Rate
Allowed for Budgeted
Actual Output Rate
(b) (a) (c)
15,000
6.00 14,850
6.00
RAM hrs. per RAM hr. RAM hrs. per RAM hr.
89,500 90,000 89,100
500 F 900 U (d)
Spending variance Efficiency variance
400 U (e)
Flexible-budget variance
a. 15,000 RAM hours 6 per RAM hour = 90,000
b. Actual VMOH = 90,000 500F (VOH spending variance) = 89,500
c. 14,850 RAM hours 6 per RAM hour = 89,100
d. VOH efficiency variance = 90,000 89,100 = 900 U
e. VOH flexible budget variance = 900U 500F = 400 U
Allocated variable overhead will be the same as the flexible budget variable overhead of 89,100. The actual variable overhead cost is 89,500. Therefore, variable overhead is underallocated by 400.
2. In the columnar presentation of fixed overhead variance analysis, all numbers shown in bold are calculated from the given information, in the order (a)(e).
FIXED MANUFACTURING OVERHEAD
Flexible Budget: Allocated:
Actual Costs Static Budget Lump Sum
Regardless of Output Budgeted Input Qty. Allowed for Budgeted
Incurred Level Actual Output Rate
(a) (b)
14,850
1.60 (c)
RAM hrs. per RAM hr.
30,375 28,800 23,760
1,575 U 5,040 U (d)
Spending variance Production-volume variance
1,575 U (e)
Flexible-budget variance
a. Actual FOH costs = 119,875 total overhead costs 89,500 VOH costs = 30,375
b. Static budget FOH lump sum = 30,375 1,575 spending variance = 28,800
c. FOH allocation rate = 28,800 FOH static-budget lump sum 18,000 static-budget RAM-hours
= 1.60 per RAM hour
Allocated FOH = 14,850 RAM hours 1.60 per RAM hour = 23,760
d. PVV = 28,800 23,760 = 5,040 U
e. FOH flexible budget variance = FOH spending variance = 1,575 U
Allocated fixed overhead is 23,760. The actual fixed overhead cost is 30,375. Therefore, fixed overhead is underallocated by 6,615.
