Fuel Cost Calculator
A friendly way to estimate what your next drive will cost — in your units, your currency, your style of driving.
Your trip will cost about
Fill in your trip, your car and fuel price — we'll tell you what it'll cost.
How it works
Tell us how far you're going, what your car typically does on a tank, and what you're paying at the pump. We convert everything behind the scenes and give you a clear cost for the trip.
How we estimate: we work out the litres of fuel your trip needs based on your car's economy, then multiply by your fuel price. City driving gets a small bump (around 20% more fuel), motorway driving gets a small discount (around 10% less) — that matches what most drivers actually see.
Units made simple: 1 mile is 1.609 km, a UK gallon is 4.546 litres, a US gallon is 3.785 litres. Switch any unit and the maths re-runs instantly.
