Estimate the fuel needed and the cost of a trip from distance, your vehicle's efficiency and the fuel price. Supports metric (L/100km) and imperial (MPG) efficiency.
Choose your distance and efficiency units, then enter the distance, your vehicle's efficiency and the fuel price (per litre for L/100km, per gallon for MPG). The calculator works out fuel used, trip cost and cost per 100 km.

A fuel cost calculator turns a distance, your vehicle's efficiency and the pump price into a realistic trip budget. It supports both common efficiency measures — litres per 100 km and miles per gallon.
Official figures come from controlled lab tests. Real economy varies with driving style, traffic, speed, load, tyre pressure, weather and air-con use — often 10–20% worse than the sticker.
No. A UK (imperial) gallon is 4.546 litres; a US gallon is 3.785 litres. This calculator uses the US gallon — convert UK MPG accordingly.
