| Cost Pool | Amount | Cost Driver | Driver Quantity | Rate | | --- | --- | --- | --- | --- | | Machine setup | $200k | Number of setups | 200 setups | $1,000/setup | | Quality control | $150k | Inspection hours | 3,000 hours | $50/hour | | Materials handling | $150k | Number of material moves | 500 moves | $300/move |

At its most fundamental level, a cost driver is the "activity" that triggers a specific expense. It acts as the input variable in the cost equation; as the frequency or intensity of the cost driver increases, the total cost associated with it rises. For example, if a factory uses electricity to run machines, the number of machine hours is a cost driver for the electricity bill. The more the machines run, the higher the cost. By identifying these drivers, accountants can analyze how specific actions correlate with financial outcomes, transforming accounting from a historical record into a diagnostic tool.
