Overview

This vehicle running cost calculator helps you estimate how much your car costs to run each month and year. Enter your monthly mileage, fuel economy, fuel price, insurance, maintenance and other regular costs to see an estimated total cost and cost per mile.

How it works

The calculator estimates how much fuel you use each month by dividing your monthly distance by your fuel economy. It then multiplies that by the fuel price to find your monthly fuel cost. Finally, it adds insurance, maintenance and other monthly costs to give a total running cost, then divides by your mileage to estimate cost per mile.
