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 78,000 units of product were as follows:

	Standard Costs		Actual Costs
Direct materials	202,800 lbs. at $5.60		200,800 lbs. at $5.40
Direct labor	19,500 hrs. at $16.60		19,950 hrs. at $17.00
Factory overhead	Rates per direct labor hr.,
	based on 100% of normal
	capacity of 20,350 direct
	labor hrs.:
		Variable cost, $4.70	$90,730 variable cost
		Fixed cost, $7.40	$150,590 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 Materials 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	$fill in the blank 7	Unfavorable
Direct Labor Time Variance	$fill in the blank 9	Unfavorable
Total Direct Labor Cost Variance	$fill in the blank 11	Unfavorable

c. Determine the variable factory overhead controllable variance, 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
