Fuel cost calculator

Work out what a journey costs at today's average UK petrol and diesel prices. Enter the miles, your car's miles per gallon and the price per litre, and Pennyfill shows the cost of the trip, and the cost each if you're sharing the drive.

Is the cheaper station worth the drive?

A station a few pence a litre cheaper can cost you more once you count the extra miles to get there. Put in how far away it is and how much you're filling up, and the calculator shows whether the detour saves you money.
