Traditional Costing and Activity-Based Costing
Traditional Costing Systems
Allocates overhead using a single predetermined rate.
 Job order costing: direct labor cost is assumed
to be the relevant activity base.

 Process costing: machine hours is the relevant
activity base.

Assumption was satisfactory when direct labor was a
major portion of total manufacturing costs.
 Wide acceptance of a high correlation between
direct labor and overhead costs.

Traditional Costing and Activity-Based Costing
The Need for a New Approach
Tremendous change in manufacturing and service
industries.
Decrease in amount of direct labor usage.

Significant increase in total overhead costs.
Inappropriate to use plant-wide predetermined
overhead rates when a lack of correlation exists.

Complex manufacturing processes may require
multiple allocation bases; this approach is called
Activity-Based Costing (ABC).

or setting up machines

Cost Drivers: any factor or activity that have a direct
cause-effect relationship with the resources consumed.

SO1 Recognize the difference between traditional costing and activity-based costing.

Traditional Costing and Activity-Based Costing
Activity-Based Costing
ABC allocates overhead costs in two stages:
Stage 1: Overhead costs are allocated to activity
cost pools.
Stage 2: The overhead costs allocated to the cost
pools is assigned to products using cost
drivers.

The more complex a product’s manufacturing
operation, the more activities and cost drivers likely
to be present.
