Activity-Based Costing

Steampunk Corporation has the following predicted indirect costs and cost drivers for 2019 for the given activity cost pools:

  Fabrication
Department
Finishing
Department
Cost Driver
Maintenance $ 84,000 42,000 Machine hours
Materials handling 126,000 63,000 Material moves
Machine 294,000 21,000 Machine setups
Inspections

-

105,000

Inspection hours
Total

$ 504,000

$ 231,000

 

The following activity predictions were also made for the year:

  Fabrication
Department
Finishing
Department
Machine hours 5,000 2,500
Material moves 1,500 750
Machine setups 350 25
Inspection hours - 500

It is assumed that the cost per unit of activity for a given activity does not vary between departments. Steampunk's president, Abner Punk, is trying to evaluate the company's product mix strategy regarding two of its product models, SW100 and SG150. The company has been using a company wide overhead rate based on machine hours but is considering switching to either department rates of activity-based rates. The production manager has provided the following data for the production of a batch of 100 units for each of these models:

  SW100 SG150
Direct materials cost $ 28,000 $ 42,000
Direct labor cost $ 11,200 $ 8,400
Machine hours (Fabrication) 250 350
Machine hours (Finishing) 100 50
Materials moves 20 40
Machine setups 5 10
Inspection hours 15 30

a. Determine the cost of one unit each of SW100 and SG150, assuming a company-wide overhead rate is used based on total machine hours.

Round rate to two decimal places.

Overhead rate based on total machine hours:  $Answer

 

per machine hour

 

Use rounded overhead rate calculated about for calculations below. Round cost answers to the nearest whole number. Round cost per unit to two decimal places.

Product Costs per Unit SW100 SG150
Direct materials
 
 
Direct labor
 
 
Manufacturing overhead
 
 
Total cost per batch
 
 
Number of units per batch
 
 
Cost per unit
 
 

b. Determine the cost of one unit of SW100 and SG150, assuming department overhead rates are used. Overhead is assigned based on machine hours in both departments.

Round to two decimal places, if applicable.

Overhead rate based on machine hours for Fabrication Dept.:  $Answer

 

per machine hour.

 

Overhead rate based on machine hours for Finishing Dept.:  $Answer

 

per machine hour.

 

Use rounded overhead rate calculated above for calculations below. Round cost answers to the nearest whole number, when needed. Round cost per unit to two decimal places, if needed.

c. Determine the cost of one unit of SW100 and SG150, assuming activity-based overhead rates are used for maintenance, materials handling, machine setup, and inspection activities.

Round rate to two decimal places, if applicable.

Activity-based overhead rates:
Maintenance
 
Materials handling
 
Machine setup
 
Inspection activities
 

Use rounded overhead rate calculated above for calculations below. Round cost answers to the nearest whole number, when needed. Round cost per unit to two decimal places, if needed.
