How it works
The tool estimates how much fuel will be left when you reach the border, how many litres a full tank would then take, and multiplies that by the price difference between the two countries. If the country you are driving into is more expensive, fill up before you cross; if it is cheaper, wait.
Price gaps between neighbours can be large because fuel duty and VAT differ from country to country. Luxembourg, for example, is often cheaper than Belgium, France and Germany, which is why border stations there are busy.
Things to keep in mind
The prices are national weekly averages. Stations near a border often price close to the neighbouring country, and motorway stations charge more. Some countries limit how much fuel you can carry in spare cans, so fill the tank only.
Frequently asked questions
Is it worth driving to another country for fuel?
Only if the saving on a full tank is larger than the fuel used on the detour. Enter the detour distance to see the break-even point.
Why are prices so different across a border?
Mostly because of taxes. Fuel duty and VAT are set nationally, and they make up roughly half of the pump price in most EU countries.
Which borders are included?
Land borders between EU countries, plus the Øresund bridge between Denmark and Sweden.
