Question

Product-Costing Accuracy, Plantwide and Departmental Rates, ABC

Escuha Company produces two type of calculators: scientific and business. Both products pass through two producing departments. The business calculator is by far the most popular. The following data have been gathered for these two products:

	Product-Related Data
	Scientific	Business
Units produced per year	76,000	760,000
Prime costs	$246,000	$2,460,000
Direct labor hours	98,000	980,000
Machine hours	49,400	494,000
Production runs	100	150
Inspection hours	2,000	3,000
Maintenance hours	2,250	9,000

	Department Data
	Department 1	Department 2
Direct labor hours:
Scientific calculator	73,800	24,200
Business calculator	107,800	872,200
Total	181,600	896,400
Machine hours:
Scientific calculator	23,100	26,300
Business calculator	351,120	142,880
Total	374,220	169,180
Overhead costs:
Setup costs	$225,500	$225,500
Inspection costs	200,000	200,000
Power	232,000	167,000
Maintenance	195,000	255,000
Total	$852,500	$847,500

Required:

1. Compute the overhead cost per unit for each product using a plantwide, unit-based rate using direct labor hours. Round your calculations and answers to the nearest cent.

Plantwide rate	$ per direct labor hour
Overhead cost per unit:
Scientific	$ per unit
Business	$ per unit

2. Compute the overhead cost per unit for each product using departmental rates. In calculating departmental rates, use machine hours for Department 1 and direct labor hours for Department 2. Round departmental rates and the overhead cost per unit to the nearest cent if rounding is required.

Departmental rates:
Department 1	$ per machine hour
Department 2	$ per direct labor hour
Overhead cost per unit:
Scientific	$ per unit
Business	$ per unit

Repeat using direct labor hours for Department 1 and machine hours for Department 2. Round departmental rates and the overhead cost per unit to the nearest cent if rounding is required.

Departmental rates:
Department 1	$ per direct labor hour
Department 2	$ per machine hour
Overhead cost per unit:
Scientific	$ per unit
Business	$ per unit

3. Compute the overhead cost per unit for each product using activity-based costing. Round your calculations and answers to the nearest cent.

	Overhead Cost
Scientific	$ per unit
Business	$ per unit
