How to calculate activity-based
customer costs.Milan company produces precision
parts for 11 major buyers. Of the 11 customers one accounts for 50% of the sales, with the remaining 10 accounting for the remaining sales. The 10 smaller companies purchase approximately equal quantities of parts. Orders placed by the smaller companies are about the same size. Data pertaining to Milan’s customer activity is on the next slide.

Currently customer driven costs are assigned based on units sold, a unit level driver.
REQUIRED: Assign cost using ABCCalculation: The appropriate drivers are orders
placed and number of sales calls. The activity rates are:
Using the information, the customer-driven costs can be assigned to each group of customers as follows:

How to calculate activity-based supplier
costs.Assume that a purchasing manager uses
two suppliers, Murray, Inc. and Plata Assoc., as the source of two machine parts: Part A1 and Part B2. Consider two activities repairing products (under warranty) and expediting products. Repairing products occurs because of parts failure (bought from suppliers). Expediting products occurs because suppliers are late in delivering needed parts. Activity cost information and other data needed for supplier costing follows:

REQUIRED: Determine the cost of each supplier using ABC.
Calculation: Using the previous data, the activity rates for assigning costs to suppliers are computed as follows:
Repair rate =
Expediting rate =
Using the above rates and the activity data, the total purchasing cost per unit for each component is computed:

Provide some examples
How to assess non-value added costs.
Consider the following two activities: (1) Performing warranty work, cost $240,000. The warranty cost of the most efficient competitor is $20,000. (2) Purchasing components, cost $300,000 (15,000 purchase orders). A benchmarking study reveals that the most efficient level would use 5,000 purchase orders and entail a cost of $110,000.
REQUIRED: Determine the non-value added cost of each activity.
