Preble Company manufactures one product. Its variable manufacturing overhead is applied to production based on direct labour-hours, and its standard costs per unit are as follows:
Direct materials: 5 kg at $10.00 per kg | $ | 50.00 |
Direct labour: 3 hours at $17 per hour | 51.00 | |
Variable overhead: 3 hours at $7 per hour | 21.00 | |
Total standard cost per unit | $ | 122.00 |
The company planned to produce and sell 24,000 units in March. However, during March the company actually produced and sold 30,600 units and incurred the following costs:
1. What is the materials price variance for March? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.).)
2. What is the materials quantity variance for March? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.).)
3. If Preble had purchased 183,000 kg of materials at $9.00 per kg and used 170,000 kg in production, what would be the materials price variance for March? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.). Do not round intermediate calculations.)

6. What is the labour efficiency variance for March? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.). Do not round intermediate calculations.)
7. What is the variable overhead spending variance for March? (Do not round intermediate calculations. Round the actual overhead rate to two decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance.).)

1) Material price variance = (10-9)*170000 = 170000 F'
2) Material quantity variance = (30600*5-170000)*10 = 170000 U
3) Material price variance = (10-9)*183000 = 183000 F'
4) Material quantity variance = (30600*5-170000)*10 = 170000 U
5) Labor rate variance = (17-18)*68000 = 68000 U
6) Labor efficiency variance = (30600*3-68000)*17 = 404600 F
7) Variable overhead spending variance = (30600*21-512040) = 130560 F
8) Variable rate variance = (7*68000-512040) = 36040 U
