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 78,000 units of product were as follows:

	Standard Costs		Actual Costs
Direct materials	226,200 lbs. at $5.30		223,900 lbs. at $5.10
Direct labor	19,500 hrs. at $17.20		19,950 hrs. at $17.60
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 20,350 direct
	labor hrs.:
		Variable cost, $3.50	$67,570 variable cost
		Fixed cost, $5.50	$111,925 fixed cost

Each unit requires 0.25 hour of direct labor.
