DEFINITION of 'Activity Cost Driver'. A factor that influences or contributes to the expense of certain business operations. In activity based costing (ABC), an activity cost driver is something that drives the cost of a particular activity. A factory, for example, may have running machinery as an activity. The activity cost driver associated with running the machinery could be machine operating hours, which would drive the costs of labor, maintenance and power consumption of running the machinery activity.
A variable cost is a cost that changes in relation to variations in an activity. In a business, the activity is frequently production volume, with sales volume being another likely triggering event.Thus, the materials used as the components in a product are considered variable costs, because they vary directly with the number of units of product produced.n a business, the activity is frequently production volume, with sales volume being another likely triggering event.
