Fuel cost calculator for road trips
Estimate petrol or diesel costs using kilometres, L/100 km and price per litre. Add tolls, parking and a return trip, then split the total.
Total trip cost
Fuel plus the tolls and parking you entered. The return doubles the distance, not the extra costs.

Distance, consumption, price. Then the extras.
Fuel needed equals distance multiplied by consumption in L/100 km, divided by 100. Multiply the fuel by its unit price, add tolls and parking, then divide by the number of people. MPG and miles are converted before calculating.
This is an estimate, not a route planner. It does not fetch live prices or calculate tolls. Enter the full trip's extra costs; wear, depreciation and time are not included.
