Amos, Inc. uses a standard cost system with the following labor standards for one unit of product: standard hours 0.2 and standard wage rate $11. During January, Amos incurred 3,781 hours of direct labor and paid $41,066 in wages in production of 18,400 units. Calculate the direct labor rate and efficiency variances and indicate whether the variances are favorable or unfavorable.

$529.34 favorable and $1,111 unfavorable

Explanation:

The computation of the direct labor rate variance is shown below:  

= Actual Hours × (Actual rate - standard rate)  

= 3,781 hours × ($41,066 ÷ 3,781 hours  - $11 per hour)  

= 3,781 hours  × ($10.86 per hour  - $11 per hour)  

= $529.34 favorable

And, the efficiency variance is

= (Standard hours - Actual hours) × standard rate

where,

Standard hours is

= 18,400 units × 0.2

= 3,680 hours

Actual hours is 3,781 hours

So, the efficiency variance is

= (3,680 hours - 3,781 hours) × $11

= $1,111 unfavorable
