About the Fuel Cost Calculator
Planning a road trip? Enter the distance, your vehicle’s mileage and today’s fuel price to see how much fuel you need and what it will cost, split between travellers.
How to use the Fuel Cost Calculator
- Enter the one-way distance in km.
- Enter your vehicle’s mileage (km per litre).
- Enter the current fuel price in your city.
- Tick round trip and add the number of people to split the cost.
Formula used
Fuel needed (L) = distance ÷ mileage. Cost = fuel needed × price per litre. Round trip doubles the distance.
