Direct Materials, Direct Labor, and Factory Overhead Cost Variance Analysis
Mackinaw Inc. processes a base chemical into plastic. Standard costs and actual costs for direct materials, direct labor, and factory overhead incurred for the manufacture of 40,000 units of product were as follows:
Standard Costs | Actual Costs | ||
Direct materials | 120,000 lb. at $3.20 | 118,500 lb. at $3.25 | |
Direct labor | 12,000 hrs. at $24.40 | 11,700 hrs. at $25.00 | |
Factory overhead | Rates per direct labor hr., | ||
based on 100% of normal | |||
capacity of 15,000 direct | |||
labor hrs.: | |||
Variable cost, $8.00 | $91,200 variable cost | ||
Fixed cost, $10.00 | $150,000 fixed cost |
Each unit requires 0.3 hour of direct labor.
Required:
a. Determine the direct materials price variance, direct materials quantity variance, and total direct materials cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.
