Fuel cost calculator
Calculate fuel use and trip cost from distance, consumption, price per litre and passengers.
Formula
Calculate fuel costs for a trip
Litres = total distance × consumption / 100. Total cost = litres × price per litre. Cost per person = total cost / passengers.
How to estimate trip fuel cost
- Enter the one-way distance, the vehicle’s average consumption in L/100 km and the price per litre.
- Choose one-way or return, then enter how many passengers share the fuel cost.
- Review the estimated litres and cost; the per-person amount splits fuel only, equally.
Example: 300 km, 6 L/100 km, €1.60/L and 2 passengers use 18 L, cost €28.80 total and €14.40 per person.
The estimate uses the average consumption you enter. It does not calculate routes or include tolls, parking or other trip expenses.
