What is activity-based costing and why is it relevant for decision making?

• A. Allocates overhead costs based on activities that drive costs.
• B. Allocates overhead based on direct labor hours only.
• C. Allocates overhead evenly across all products.
• D. Allocates fixed costs to marketing expenses.

Answer: (A)

Activity-based costing assigns overhead to products based on activities that drive costs, using cost drivers to reflect how much of each activity a product consumes. This approach gives a more accurate picture of true resource use, which in turn supports better decisions about pricing, product mix, process improvements, and cost management. By linking costs to the actual activities that cause them (such as setup, machining, or inspection), it reveals whether a product is truly profitable and where improvements can reduce costs. Other methods miss these dynamics. Allocating overhead by direct labor hours ignores the contribution of non-labor resources like machinery, setups, and quality checks. Spreading overhead evenly across products doesn’t reflect actual usage and can distort profitability. And assigning fixed costs to marketing expenses mixes unrelated costs, obscuring how marketing activities actually drive costs.
