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	203,000 lbs. at $5.90		201,000 lbs. at $5.70
Direct labor	17,500 hrs. at $17.70		17,900 hrs. at $18.00
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 18,260 direct
	labor hrs.:
		Variable cost, $2.80	$48,510 variable cost
		Fixed cost, $4.40	$80,344 fixed cost

Each unit requires 0.25 hour of direct labor.

Required:

a. Determine the direct materials price variance, direct materials quantity variance, and total direct materials cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

Direct Material Price Variance	$	Favorable
Direct Materials Quantity Variance	$	Favorable
Total Direct Materials Cost Variance	$	Favorable

b. Determine the direct labor rate variance, direct labor time variance, and total direct labor cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

Direct Labor Rate Variance	$	Unfavorable
Direct Labor Time Variance	$	Unfavorable
Total Direct Labor Cost Variance	$	Unfavorable

c. Determine variable factory overhead controllable variance, the fixed factory overhead volume variance, and total factory overhead cost variance. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number.

Variable factory overhead controllable variance	$	Favorable
Fixed factory overhead volume variance	$	Unfavorable
Total factory overhead cost variance	$	Unfavorable
