Chapter 23 Performance Evaluation using variances from Standard Costs 1117 PR 23-3B Direct materials, direct labor, and factory overhead cost variance analysis OBJ. 3 4 Road Gripper Tire Co. manufactures automobile tires. Standard costs and actual costs for direct materials, direct labor, and factory overhead incurred for the manufacture of 4,160 follows: Actual Costs Standard Costs Direct materials 100,000 lbs. at $640 101,000 lbs. at $650 Direct labor 2,080 hrs, at $15.75 2,000 hrs, at $15.40 Factory overhead Rates per direct labor hr. based on 100% of normal capacity of 2,000 direct labor hrs. Variable cost, $4.00 $8,200 variable cost $12,000 fixed cost Fixed cost, $6.00 Each tire requires 0.5 hour of direct labor. Instructions Determine (a) the direct materials price variance, direct materials quantity variance, and total direct materials cost variance; (b the direct labor rate variance, direct labor time vari- ance, and total direct labor cost variance; and (c) the variable factory overhead controllable variance, fixed factory overhead volume variance, and total factory overhead cost variance.
