Exercise 21-13 (30 minutes)
1. Preliminary computations
Actual quantity: 22,000 bd. ft. (given)
Standard quantity: 3,000 units x 8 bd. ft./unit = 24,000 bd. ft.
Actual price: $266,200/22,000 bd. ft. = $12.10/bd. ft.
Standard price: $12.00/bd. ft. (given)

(Quantity variance)
Alternate solution format
Price variance = AQ x (AP – SP)
= 22,000 board feet x ($12.10 - $12.00)
= $2,200 U
Price variance......................$ 2,200 U
Quantity variance................ 24,000 F
Total variance......................$21,800 F
2. The unfavorable price variance means the actual price paid is more than
the budgeted price. The favorable quantity variance means the actual
forwarded, distributed, or posted on a website, in whole or part.

October variances
Preliminary computations
Actual hours: 16,250 hours (given)
Standard hours: 5,600 units x 3 hrs./unit = 16,800 hrs.
Actual rate: $247,000/16,250 hours = $15.20/hr.
Standard rate: $15.00/hr. (given)

(Total labor variance)
Efficiency variance = (AH - SH) x SR
= (16,250 – 16,800) hours x $15.00 per hour
= (-550 hours) x $15.00 per hour
= $8,250 F

2.
The unfavorable labor rate variance in October means the actual rate for an
hour of labor is greater than budgeted. The favorable labor efficiency
variance means the actual hours used are less than budgeted. Together,

Variable overhead spending and efficiency variances
Actual Overhead

Applied Overhead
SH x SVR
$25,000 F
(Total variable overhead variance)
Interpretation:
The $15,000 unfavorable spending variance means the actual cost of variable
overhead is more than budgeted. This unfavorable variance can occur
because the cost of variable overhead is greater than budgeted or because
more variable items are consumed than anticipated. It could also be a

Interpretation
The $28,600 unfavorable spending variance means actual cost of fixed
overhead is more than budgeted.
