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 6,400 units of product were as follows:

	Standard Costs		Actual Costs
Direct materials	8,300 lb. at $4.80		8,200 lb. at $4.70
Direct labor	1,600 hrs. at $16.10		1,640 hrs. at $16.30
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 1,670 direct
	labor hrs.:
		Variable cost, $4.30	$6,810 variable cost
		Fixed cost, $6.80	$11,356 fixed cost

Each unit requires 0.25 hour of direct labor.
