How it works
- Cost per mile is the price a litre × 4.546 litres in a UK gallon ÷ your miles per gallon.
- A year is 52 weeks and a month is a twelfth of a year.
- The starting prices are the median for each fuel near the last place you looked at on this site, or the UK median if you haven't looked at one recently. They are not the price at any one station. See about the data for how we work it out.
- The figures you type are worked out in your browser. Your fuel economy is saved on this device with your savings settings, so the place pages use it too. The miles and prices you type here are not saved.
