*Contains direct materials, direct labor, and variable manufacturing overhead.

Janet Dunn, who has just been appointed general manager of the Westwood Plant, has been given instructions to “get things under control.” Upon reviewing the plant’s income statement, Ms. Dunn has concluded that the major problem lies in the variable cost of goods sold. She has been provided with the following standard cost per swimming pool:

Standard Quantity or Hours Standard Price
or Rate
Standard Cost
Direct materials 3.9 pounds $

2.30

per pound $ 8.97
Direct labor 0.8 hours $

6.90

per hour 5.52
Variable manufacturing overhead 0.6 hours* $

2.40

per hour

1.44

Total standard cost per unit $ 15.93

*Based on machine-hours.

During June, the plant produced 6,000 pools and incurred the following costs:

Purchased 28,400 pounds of materials at a cost of $2.75 per pound.

Used 23,200 pounds of materials in production. (Finished goods and work in process inventories are insignificant and can be ignored.)

Worked 5,400 direct labor-hours at a cost of $6.60 per hour.

Incurred variable manufacturing overhead cost totaling $10,920 for the month. A total of 3,900 machine-hours was recorded.

It is the company’s policy to close all variances to cost of goods sold on a monthly basis.

Required:

1. Compute the following variances for June:

a. Materials price and quantity variances.

b. Labor rate and efficiency variances.

c. Variable overhead rate and efficiency variances.

2. Summarize the variances that you computed in (1) above by showing the net overall favorable or unfavorable variance for the month.

1 a Materials Price Variance = (Actual Price- Standard Price)*Actual Materials used
(2.75-2.30)*23200
10440 U
Standard Quantity used = 3.9*6000 23400
Materials Quantity Variance = (Actual Materials used - Standard Quantity)*Standard Rate
(23200-23400)*2.30
460 F
Standard Quantity used = 3.9*6000 23400
b Labor Rate Variance = (Actual Rate - Standard Rate)*Actual Hours
(6.60-6.90)*5400
1620 F
Labor Efficiency Variances = (Actual Labor hours - Standard Labor Hours)*Standard Rate
(5400-4800)*6.90
4140 U
Standard Labor Hours = 6000*0.80 4800
c Variable overhead Rate = (Actual Rate - Standard Rate)*Actual Hours
(2.80-2.40)*3900
1560 U
Actual Rate = 10920/3900 2.80
Variable Efficiency Variance = (Actual Labor hours - Standard Labor Hours)*Standard Rate
(3900-3600)*2.40
720 U
Standard Labor Hours = (0.60*6000) 3600
