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 6,000 units of product were as follows:

	Standard Costs	Actual Costs
Direct materials	7,800 lb. at $5.30	7,700 lb. at $5.20
Direct labor	1,500 hrs. at $16.20	1,530 hrs. at $16.60
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 1,560 direct
	labor hrs.:
		Variable cost, $4.70	$6,980 variable cost
		Fixed cost, $7.40	$11,544 fixed cost

Each unit requires 0.25 hour of direct labor.
