Direct Materials, Direct Labor, and Factory Overhead Cost Variance Analysis

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 tires were as follows:

	Standard Costs		Actual Costs
Direct materials	100,000 lbs. at $6.40		101,000 lbs. at $6.50
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
		Fixed cost, $6.00	$12,000 fixed cost

Each tire requires 0.5 hour of direct labor.
