Document Summary
Traditionally, in a job order cost system and process cost system, overhead is allocated to a job or function based on direct labor hours, machine hours, or direct labor dollars. In such companies, activity-based costing (abc) is used to allocate overhead costs to jobs or functions. Activity-based costing assumes that the steps or activities that must be followed to manufacture a product are what determine the overhead costs incurred. Each overhead cost, whether variable or fixed, is assigned to a category of costs. These cost categories are called activity cost pools. Cost drivers are the actual activities that cause the total cost in an activity cost pool to increase. The number of times materials are ordered, the number of production lines in a factory, and the number of shipments made to customers are all examples of activities that impact the costs a company incurs.
