Explain the fundamentals of activity-based costing (ABC) and activity-based management (ABM).
Learning Objective 1
Activity-Based Costing (ABC)
A method of attributing costs to products based on:
Costs Activities Products
• assigning costs of resources to activities
• assigning costs of activities to products
Unit-Based Costing (UBC)
The traditional method of allocating costs (manufacturing overhead) to products based on number of units produced. If only three products are produced (one of each), then:
Costs Production Departments
Products
$9,000 Overhead
$3,000
Overhead per product

Does a hammer really cost THAT MUCH?
If a UBC factory produces only three products (a hammer, a clock, and a Ferrari) and a hammer incurs $4 of direct labor and materials, how much will the hammer cost if manufacturing overhead is allocated evenly over finished products?

Overhead per product
Under UBC (unit-based costing), some products may be inappropriately assigned costs that actually belong to another product line (in this case, the hammer and clock are obviously cross-subsidizing the Ferrari product line).

In actuality, most of the $9,000 manufacturing overhead is attributable to the Ferrari, revealing it to
be the real money loser.
In actuality, most of the $9,000 manufacturing overhead is attributable to the Ferrari, revealing it to be the real money loser,
BUT because the other products are cross-subsidizing, they appear unprofitable and will be discontinued from production.
