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

Adamantane 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 15,000 units of product were as follows:

	Standard Costs		Actual Costs
Direct materials	5,000 lbs. at $50.00		4,950 lbs. at $50.60
Direct labor	3,000 hrs. at $25.00		2,945 hrs. at $25.60
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 3,200 direct
	labor hrs.:
		Variable cost, $5.50	$16,680 variable cost
		Fixed cost, $4.00	$12,800 fixed cost

Each unit requires 0.2 hour of direct labor.
