UK petrol and diesel journey cost calculator
What will the journey cost in petrol or diesel? Enter the miles, find your car or type its mpg, and we’ll use the latest UK average pump price. Nothing you enter leaves your browser.
Enter the distance, pick your vehicle or enter its fuel use, and check the fuel price to see what the trip costs.
This is an estimate, not a quote. Real fuel use depends on how you drive, traffic, hills and road surface, the load, tyre pressure, air conditioning and the state of the vehicle. Vehicle figures are typical, not your car’s, and the distance you actually drive may differ from the map. Pump prices change, often monthly.
