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 4,400 units of product were as follows:

	Standard Costs		Actual Costs
Direct materials	5,700 lb. at $5.40		5,600 lb. at $5.30
Direct labor	1,100 hrs. at $17.00		1,130 hrs. at $17.30
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 1,150 direct
	labor hrs.:
		Variable cost, $3.40	$3,700 variable cost
		Fixed cost, $5.40	$6,210 fixed cost

Each unit requires 0.25 hour of direct labor.
