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.
