Journey cost calculator
Calculate whether cheaper fuel is really worth it
A journey cost calculator should not stop at miles and MPG. Route & Fuel helps you think about pump price, detour distance, traffic/time and the fuel used reaching the station.

Count the detour, not just the destination
A station that is cheap but far away can cost more once extra miles are included.
Personalise the estimate to your car
Vehicle MPG and fuel type make the saving estimate much closer to a real fill-up decision.
Better calculation
From simple fuel cost to real-world route savings
Basic fuel calculators estimate the cost of a journey. Route & Fuel goes further by helping you compare whether a cheaper stop still makes sense once the extra drive is included.
This is especially useful for longer UK journeys, motorway routes and areas where supermarket and branded fuel prices can vary by several pence per litre.
Lead to app
Use the app for the personalised calculation
The website can explain the model and show public price coverage. The app can apply your location, route, chosen fuel type, vehicle MPG and tank context before you fill up.
That means the app is better placed to answer the question drivers actually care about: should I stop here, carry on, or take a small detour?

Questions drivers ask
How do I calculate fuel cost for a journey?
Use distance, fuel economy and the price per litre. Route & Fuel adds route-aware context so cheaper fuel can be checked against detour distance and fuel used.
Can cheaper fuel cost more overall?
Yes. If the detour is long enough, the extra fuel and time can reduce or remove the saving from a lower pump price.
Does MPG matter when choosing a fuel stop?
Yes. A vehicle with lower MPG uses more fuel on detours, so the true saving can be very different between cars.
