Quickly and easily calculate the price of your journey using our petrol cost calculator. Simply enter the details of your journey above. Whether you want to estimate how much it will cost to fill up your car or to charge a friend for a lift, finding the price for the amount of petrol that is needed for your journey has never been simpler! (Please remember: all prices that are calculated are ESTIMATES ONLY). We'd love to hear your feedback – if you have any thoughts, comments, questions, or issues, then please let us know! Your opinion is important to us and will help us to improve the site.

To get started, input your start and end locations. You can use a postcode, a street name, or even the name of a town or city. If you wish to calculate the price to your destination and back, tick the "Return Journey?" checkbox. The distance will automatically be determined, eliminating the need for guesswork.

The fuel price is the average for the whole of the UK and is updated daily, but feel free to change it if you know the price at your local petrol station. Next, enter your car's MPG (miles per gallon) value. We understand that it is not always possible to drive optimally; therefore, you can choose a "Non-optimal Driving Offset" option, which will take this into account (a sensible value to enter is around 10-15%).

Finally, let us know if you have any passengers in your car. This will allow you to divide the total petrol cost of your journey amongst everyone who is travelling with you. Whether or not you want to include the driver in the calculation is completely up to you. If you choose not to include the driver, you will be able to specify a profit margin - just enter the amount you want in addition to the fuel cost as a percentage.
