Cost driver definition

What is a Cost Driver?

A cost driver triggers a change in the cost of an activity. The concept is most commonly used to assign overhead costs to the number of produced units. It can also be used in activity-based costing analysis to determine the causes of overhead, which can be used to minimize overhead costs. A large number of cost drivers may be used within an activity-based costing system. If a business is only concerned with following the minimum accounting requirements to allocate overhead to produced goods, then just a single cost driver should be used.

Examples of Cost Drivers

Here are several examples of the cost drivers that you could use in an activity-based costing analysis:

  • The number of customer contacts made

  • The number of direct labor hours worked

  • The number of engineering change orders issued

  • The number of machine hours used

  • The number of product returns from customers

  • The number of production orders initiated

  • The number of purchase orders issued
