Activity-Based Costing Johnson Marine manufactures marine radios in three models the 1600 model for the small boat enthusiast who will not venture far from shore, and the 2400 and 3600 models for the those with the need for more features, range, and sensitivity. Johnson manufactures only these three products. Johnson has the following manufacturing activities and the budgeted cost for each:

 

Cost

Setup labor

$ 231,000

Equipment

135,660

Assembly

739,500

Materials handling

405,000

Purchasing

92,400

Inspection

325,000

 

$1,928,560

Johnson uses a volume-based costing system that is based on labor-hours, since the assembly operation is the largest cost operation in the company. The direct labor rate is $22 per hour. Johnson is considering an ABC approach to calculating product cost and has selected the following cost drivers for each activity:

Activity

Setup labor

Number of setups

Equipment

Machine-hours

Assembly
