Activity Based Costing Example / Problem / Format

Learning Objectives:

  1. Perform the first stage allocation of overhead costs to the activity cost pools.
  2. Compute activity rates for the activity cost pools.
  3. Construct a table showing the overhead costs of units and four orders.

Ferris Corporation makes a single product – a fire resistant commercial filing cabinet – that it sells to office furniture distributors. The company has a simple ABC system that it uses for internal decision making. The company has two overhead departments whose costs are listed below:

Manufacturing overhead $5,00,000
Selling and administrative overhead $300,000

Total overhead costs $8,00,000

 The company’s activity based costing system has the following activity cost pools and activity measures:

Activity Cost Pool Activity Measures
Assembling units Number of units
Processing orders Number of orders
Supporting customers Number of customers
Other Not applicable

Costs assigned to the “other” activity cost pool have no activity measure; they consist of the costs of unused capacity and organization-sustaining costs – neither of which are assigned to products, orders or customers.

Ferris Corporation distributes the costs of manufacturing overhead and of selling and administrative overhead to the activity cost pools based on employee interviews, the results of which are reported below:

Distribution of Resource Consumption Across Activity Cost Pools

Assembling Units Processing Orders Supporting Customers Other Total
Manufacturing overhead 50% 35% 5% 10% 100%
Selling and administrative overhead 10% 45% 25% 20% 100%
Total activity 1,000 units 250 orders 100 customers

Required:

  1. Perform the first stage allocation of overhead costs to the activity cost pools.
  2. Compute activity rates for the activity cost pools.
  3. Office Mart is one of the Ferris Corporation’s customers. Last year Office Mart ordered filing cabinets four different times. Office Mart ordered a total of 80 cabinets during the year. Construct a table showing the overhead costs of these 80 units and four orders.

Solution:

1. The first stage allocation of costs to the activity cost pools appears below:

                                         Activity Cost Pools


Assembling Units Processing Orders Supporting Customers Other Total
Manufacturing overhead $250,000 $175,000 $25,000 $50,000 $500,000
Selling and administrative overhead 30,000 135,000 75,000 60,000 300,000





Total activity $280,000 $310,000  $100,000 $110,000 $800,000

2. The activity rates for the activity cost pools are:

Activity Cost Pools Total Cost Total Activity Activity Rate
Assembling units $280,000 1,000 units $280 per unit
Processing orders $310,000 250 units $1,240 per order
Supporting customers $100,000 100 customers $1,000 per customer

3. The overhead cost for the four orders of a total of 80 filing cabinets would be computed as follows:

Activity Cost Pools Total Cost Total Activity Activity Rate
Assembling units $280 per unit 80 units $22,400
Processing orders $1,240 per order 4 units $4,960
Supporting customers $1000 per customer Not applicable

4. The product and customer margin can be computed as follows:

Filing Cabinet Product Margin:
Sales ($595 per unit × 80 units) $47,600
Cost:
     Direct materials ($180 per unit × 80 units) $14,400
     Direct materials ($50 per unit × 80 units) 4,000
     Volume related overhead (above) 22,400
     Order related overhead (above) 4,960 45,760
