The records of Norton, Inc. show the following for July. Standard labor-hours allowed per unit of output 1.2 Standard variable overhead rate per standard direct labor-hour $ 45 Good units produced 60,000 Actual direct labor-hours worked 73,600 Actual total direct labor $ 2,370,000 Direct labor efficiency variance $ 48,000 U Actual variable overhead $ 3,072,000 Required: Compute the direct labor and variable overhead price and efficiency variances. (Do not round intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, or "U" for unfavorable. If there is no effect, do not select either option.)

Direct labor rate variance = $162,000 U

Direct labor efficiency variance = $48,000 U

Variable overhead rate variance = $240,000 F

Variable overhead efficiency variance = $72,000 U

Explanation:

As per the data given in the question,

Direct labor efficiency variance = (Standard hour - Actual hour) × Standard rate

-$48,000 = (60,000 * 1.2 - 73,600) × Standard rate

Standard rate = -$48,000 ÷ -1,600

= 30

Direct labor rate variance = (Standard rate × Actual hour - Direct labor)

= (30 × 73,600 - $2,370,000)

= -$162,000

= $162,000 U

Direct labor efficiency variance = $48,000 U

Variable overhead rate variance = (Direct labor hour × Actual hour - actual variable overhead)

= ($45 × 73,600 -$3,072,000)

= $240,000 F

Variable overhead efficiency variance = (72,000 - 73,600) × $45

= $72,000 U
