Question

Serva, Inc., manufactures and sells two products: Product R4 and Product N4. Data concerning the expected production of each product and the expected total direct labor-hours (DLHs) required to produce that output appear below:


The direct labor rate is $24.70 per DLH. The direct materials cost per unit for each product is given below:


The company is considering adopting an activity-based costing system with the following activity cost pools, activity measures, and expected activity:


The activity rate for the Labor-Related activity cost pool under activity-based costing is closest to:

$15.23 per DLH

$238.33 per DLH

$72.50 per DLH

$48.33 per DLH

Expected Production Direct Labor-Hours Per Unit Total Direct Labor-Hours Product R4 800 6.0 4,800 Product N4 300 3.0     900 Total direct labor-hours 5,700

Explanation / Answer

The activity rate for the Labor-Related activity cost pool under activity-based costing is closest to $15.23 per DLH is calculated as follows.

Activity rate for the Labor-Related activity cost pool = Labor rated overhead cost / total number of labor hours

                                                                                  = $86,811 / 5,700

                                                                                   = $15.23 per DLH

For the asker:

For the benefit of student the unit product cost of product R4 is calculated as follows.
