At the beginning of 2017, DDC budgeted annual production of 420,000 doorknobs and
adopted the following standards for each doorknob:
Input Cost/Doorknob
Direct materials (brass) 0.3 lb. @ $10/lb. $ 3.00
Direct manufacturing labor 1.2 hours @ $17/hour 20.40
Manufacturing overhead:
Variable $5/lb. × 0.3 lb. 1.50
Fixed $15/lb. × 0.3 lb. 4.50
Standard cost per doorknob $29.40
Actual results for April 2017 were as follows:
Production 29,000 doorknobs
Direct materials purchased 12,400 lb. at $11/lb.
Direct materials used 8,500 lbs.
Direct manufacturing labor 29,200 hours for $671,600
Variable manufacturing overhead $ 65,100
Fixed manufacturing overhead $158,000
Required:
1. For the month of April, compute the following variances, indicating whether each is
favorable (F) or unfavorable (U):
a. Direct materials price variance (based on purchases)
b. Direct materials efficiency variance
c. Direct manufacturing labor price variance
d. Direct manufacturing labor efficiency variance
e. Variable manufacturing overhead spending variance
f. Variable manufacturing overhead efficiency variance
g. Production-volume variance
h. Fixed manufacturing overhead spending variance
2. Can Williams use any of the variances to help explain any of the other variances? Give
examples.
