Estimate your range
What your result means
The result estimates how many miles £25 of petrol could buy at the price and UK MPG entered. The petrol price determines how many litres the budget purchases, while MPG determines how far those litres may take the vehicle.
It is a fuel-only range estimate. Real-world range can vary with driving conditions and the MPG you actually achieve.
Worked example
Example only: £25, 142p per litre and 45 UK MPG. For a larger petrol top-up, the comparison shows how price or budget changes the estimate.
- Petrol purchased
- 17.6 litres
- UK gallons
- 3.87
- Estimated range
- 174.3 miles
The calculator uses the same three steps: buy litres, convert to UK gallons, then apply UK MPG.

| £25 | 174.3 miles |
Helpful questions
Does £25 of petrol always give the same range?
No. The estimate changes with the petrol price and the UK MPG entered. The same budget buys fewer litres at a higher price, while a different MPG changes the estimated distance.
What MPG should I enter for my petrol vehicle?
Use a measured real-world UK MPG where possible. The MPG Calculator can work it out from miles driven and litres used.
Why might my actual petrol range be different?
Traffic, speed, load, weather and driving style can change real petrol consumption. This calculation estimates range from the price and UK MPG you enter.
Does this use UK or US MPG?
It uses UK / imperial MPG, based on a 4.54609-litre UK gallon. Convert US MPG to UK MPG if your figure uses a US gallon.
