The following labor standards have been established for a particular product: standard labor hours per unit of output 4.3 hoursstandard labor rate $ 20.10 per hourthe following data pertain to operations concerning the product for the last month: actual hours worked 6,900 hoursactual total labor cost $ 139,380actual output 1,500 unitsrequired: a. what is the labor rate variance for the month? b. what is the labor efficiency variance for the month?

1. $690 (favorable)

2.  $9045 (favorable)

Explanation: These can be computed as follows :-

Labor rate variance = Actual labor cost - (standard rate * actual hours)

                                  =  $139,380 - ( $20.1 * 6900 hours )

                                  = $690 (favorable)

.

Labor efficiency variance = ( Actual hours - standard hours ) * (standard rate )

                                          = [6900 hours - (1500 units * 4.3 hours) ] * ($20.1)

                                          = $9045 (favorable)
