Activity-Based CostingActivity-Based Costing

The key assumption in Activity-Based Costing is that overhead costs are caused by a variety of activities, and that different products utilize these activities in a non-homogeneous fashion. ABC attempts to select as the allocation base the best cost driver for each overhead cost item; i.e., the cost driver that best captures the cause and effect relation-ship between products and overhead costs.
