In-depth explanation
Estimate how much a journey will cost in fuel using distance, your vehicle’s efficiency, and the current fuel price. Supports common UK and US units. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
Use your car’s typical real-world MPG or L/100km rather than the brochure figure for a more realistic estimate. Switch country/units to match how you measure distance and fuel.
It estimates fuel cost only. Tweak the inputs above to compare options, then copy or note the result you need.
Brochure MPG is measured in a lab cycle. Real-world figures are usually worse, especially on short trips, in winter, or with a heavy load. Use a recent fill-up from the MPG Calculator if you have the numbers.
Fuel price should be what you actually pay, including the unit you buy in (p/litre vs $/gallon). The estimate is fuel only: parking, tolls, and wear are extra. Switch UK/US units so distance and economy match how you think.
