Fuel is the running cost drivers feel every week, and small differences in consumption compound into serious money over a year. The fuel cost calculator turns any trip or monthly distance into an exact spend using your car's consumption and today's fuel price, while the MPG calculator converts between MPG, litres per 100 km and km per litre so you can compare cars sold in different markets on equal terms.
Thinking of switching to electric? The EV vs petrol calculator compares total running costs side by side: home and public charging prices against petrol spend, adjusted for your annual mileage. Run your own numbers before your next purchase or lease decision, because the cheapest option depends entirely on how far you drive and what you pay per unit of energy.
