Activity-Based Costing (ABC)Activity-Based Costing (ABC)

1. Activity-based costing changes the way overhead costs are allocated.

2. When identifying specific activities, inefficiencies may be discovered and eliminated, reducing the product’s cost.

3. Traditional cost accounting undercosts complex products and overstates their profit margins.

4. ABC may be used for decision making but not necessarily for inventory valuation.
