How Route & Fuel calculates savings.

Route & Fuel is designed around net saving: the useful amount left after comparing pump prices with route, detour and vehicle details.

The core idea

Cheap fuel is only useful if getting to it does not wipe out the benefit. Route & Fuel is built to keep that comparison visible in the app.

Inputs the saving can use

Fuel priceStation price per litre
Fill amountTank or estimated litres
Route detailsDistance and detour
VehicleMPG and fuel type

Example net saving flow

  1. Compare candidate station prices against a relevant nearby or on-route benchmark.
  2. Estimate the gross saving based on expected litres.
  3. Estimate extra fuel used by the detour using vehicle details.
  4. Show the remaining net saving clearly before the driver commits.

Why this matters

Without route and vehicle details, every driver can be shown the same “cheap” result. Route & Fuel aims to make the result more useful for the specific driver and journey.

Important note

Fuel prices, availability and journey conditions can change. Route & Fuel is decision support, not a guarantee. Drivers should always confirm the final price at the station.
