About this digital tool
A fuel cost calculator estimates how much a trip will cost by combining distance, fuel consumption and the price per liter. The basic formula is: fuel needed = distance x consumption per 100 km / 100, then cost = fuel needed x fuel price. This is useful for planning a commute, a delivery route or a longer road trip before you leave. If you know the return distance, enter the full round trip instead of doubling the result later. For the most realistic estimate, use your vehicle's recent average consumption and today's local fuel price.
How to use
- Enter the trip distance.
- Enter your vehicle's fuel consumption per 100 km.
- Enter the fuel price per liter.
- Review the estimated liters needed and total trip cost.
Frequently asked questions
How do you calculate fuel cost for a trip?
Multiply distance by consumption per 100 km, divide by 100, then multiply by the fuel price per liter.
Why can the real cost differ?
Traffic, hills, tire pressure, weather, driving style and cargo weight can all change real fuel consumption.
How do I work out the fuel needed for a trip?
Divide the distance by 100 and multiply by the consumption per 100 km. For 250 km at 6.5 L/100 km you need 16.25 litres. Multiply that by the price per litre to get the cost.
How do I split the trip cost between passengers?
Take the total cost and divide it by the number of people. For a return trip, turn on the return option so the distance is counted twice.
