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 70,000 units of product were as follows:

	Standard Costs		Actual Costs
Direct materials	231,000 lbs. at $5.00		228,700 lbs. at $4.80
Direct labor	17,500 hrs. at $16.20		17,900 hrs. at $16.50
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 18,260 direct
	labor hrs.:
		Variable cost, $3.10	$53,710 variable cost
		Fixed cost, $4.90	$89,474 fixed cost

Each unit requires 0.25 hour of direct labor.
