Chapter 5 - Activity-Based Costing and Customer Profitability Analysis
5-45 (continued-3)
Activity-based costing provides ADA with more detailed and better
estimates of product costs. For example by using ABC, ADA becomes
aware that the cost of Diomycin is lower ($0.4818 per capsule compared
From the schedule, activity-based costing assigns more overhead to
the lower-volume Addolin because the production of Addolin requires
more setups, inspection, supervision, formulation and management. The
current direct-labor-hours based costing system failed to assign costs of
all activities. As a result, Diomycin and Homycin subsidized Addolin.
The production department at ADA also benefits under ABC. ABC
provides better costing information on the cost of each of the activities
and identifies cost drivers and the activities that consume resources and
raise cost. The additional information enables production mangers to
manage cost by managing activities and cost drivers.
Adopting the ABC method is strategically important for ADA.
Because the ABC method provides ADA with a more accurate product

(20min)
1. The TDABC rate per minute for MMI is determined as follows:
Total Projected Costs ÷ Practical Capacity
= $9,515,500 ÷ 12,045,000 = $0.79 per minute
The charge to AS should be estimated as follows:

The revised proposal would show:
Cost for Autos (1,141,000 x $.79) $901,390
Cost for Trucks (473,750 x $.79) $374,263
Total Cost $1,275,653

Unused capacity with the AS engagement 474,154
The 2,088,904 minutes of unused capacity is relatively large (17.3% of total
capacity) and has important implications for MMI’s operating and marketing
strategy. First, it indicates the importance of getting the AS engagement,
which would reduce unused capacity to 3.9%, a substantial improvement.

The cost of the unused capacity could be determined as follows:

One significant concern with such a small level of planned unused
run out of capacity, which could be problematic.
