Fuel Cost Calculator
Work out the fuel cost of a journey from its distance, your fuel economy and the fuel price.
What a drive actually costs in fuel
The fuel cost of a trip comes down to three things: how far you are going, how efficient your vehicle is, and the price of fuel. This combines them into the cost of the journey, so you can budget for a trip, compare driving against other transport, or split fuel fairly with passengers.
Enter the distance, your economy and the fuel price to see the cost.
Real economy differs from the sticker
For an accurate figure, use your real-world fuel economy rather than the manufacturer's official number, which is measured under ideal conditions and is usually optimistic. Your actual consumption depends on how and where you drive — motorway cruising is efficient, stop-start city traffic and hills are not, and a loaded car uses more. Working from the economy you genuinely get gives a trip cost you can trust.
Frequently asked questions
Should I use the official fuel economy figure?
Use your real-world economy if you can — official figures are measured in ideal conditions and tend to be optimistic.
What affects fuel cost most on a trip?
The distance and your economy, which itself depends on driving style and conditions — motorway cruising beats stop-start city traffic.
