The company has developed standard costs for its several products. It sets standard costs for each year in the preceding October. The standard cost of a sprinkler this year was $4.00, computed as follows:
|
Direct materials
|
|
|
|
Aluminum
|
0.2 pound x $0.40 per pound
|
$0.08
|
|
Plastic
|
1.0 pound x $0.38 pound
|
$0.38
|
|
Production Labor
|
0.3 hour x $9.00 per hour
|
$2.70
|
|
Overhead*
|
|
|
|
Variable
|
0.3 hour x $1.60 per hour
|
0.48
|
|
Fixed
|
0.3 hour x $1.20 per hour
|
0.36
|
|
TOTAL
|
|
$4.00
|
Calculated using 30,000 production labor-hours as normal capacity
During February of this year, 8,500 good sprinklers were manufactured. The following costs were incurred and charged to production.

Aluminum

1,800 pounds x $0.48 per pound
|
$864

Plastic shortages forced the company to purchase lower-grade plastic than called for in the standards, which increased the number of sprinklers rejected on inspection.
Organet Stamping Company manufactures a variety of products made of plastic and aluminum components. During winter months, substantially all production capacity is devoted to lawn sprinklers for the following spring and summer seasons. Other products are manufactures during the remainder of the year. Because a variety of products are manufactured throughout the year, factory volume is measured using prodction labor-hours rather than units of production.
Based on the data above, we are required to compute the following for February:
1. Total variance from standard cost of the costs charged to production
2. Spending or budget variance for the fixed protion of the overhead costs
3. The labor efficience variance
4. The labor rate variance
5. Total variable cost variance
6. Variable overhead spending, efficiency, and flexible budget variances
7. Factory overhead production volume variance
8. The materials variances. Also comment on the effects of using materials of different grades.
