About CarRunningCosts

CarRunningCosts is a small collection of free calculators for anyone who wants to know exactly what driving really costs — for a single journey, over a year, split between passengers, or compared against going electric.

We built these tools to be quick, honest, and free of clutter: enter a few numbers, get a clear answer, no sign-up required. The calculations use standard UK units and conversions (imperial gallons, pence per litre, pence per kWh) and are provided for general guidance — always double-check important financial decisions with up-to-date figures for your specific vehicle and tariff.
