RE: Activity Based Costing
Traditional methods of product costing have typically assigned
manufacturing overhead costs based on direct labor hours, direct labor
cost, or machine hours. These bases are all highly correlated with the
volume of output. Plantwide and departmental overhead rates based on
these measures are therefore appropriately referred to as “volume–based.”
While the total costs being assigned to products using volume-based
methods may be the same as the costs assigned in activity-base costing,
ABC differs in that it focuses on the consumption of resources (i.e. inputs)
occur.
An advantage of ABC is that it more accurately divides the total costs
among various product lines based on the resources that go into those
products. Disadvantage of ABC are that it can be difficult and costly to
implement.
