14. 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 74,000 units of product were as follows:

	Standard Costs		Actual Costs
Direct materials	222,000 lbs. at $5.70		219,800 lbs. at $5.50
Direct labor	18,500 hrs. at $18.10		18,930 hrs. at $18.30
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 19,310 direct
	labor hrs.:
		Variable cost, $4.50	$82,420 variable cost
		Fixed cost, $7.10	$137,101 fixed cost

Each unit requires 0.25 hour of direct labor.
