Car running-cost estimator

Fuel is usually the biggest running cost after depreciation. Put in the car’s real economy, your mileage and your local fuel price — get the honest yearly, monthly and per-mile numbers.

Use your own achieved figure if you have one — official WLTP figures are usually optimistic. Petrol/diesel only.

Defaults to 145p as an editable placeholder — check a price near you and type it in. Fuel prices change frequently.
