Fuel Cost Calculator
Estimate the fuel cost of a trip from its distance, your vehicle efficiency (L/100 km or mpg) and the price of fuel. Add passengers to split the cost per person, and toggle round trip to double the distance automatically.

The estimate covers fuel only — tolls, parking, depreciation and wear are not included. Carpooling splits the fuel bill and is far cheaper than driving separate cars.

Formula
fuel_L = distance_km × (L/100 km) ÷ 100 · cost = fuel_L × price · per person = cost ÷ passengers
Pro tips
- • Driving at 90–110 km/h instead of 130 can cut fuel use by 10–20%.
- • Round trip toggle doubles distance — fuel burned is the same both ways, so no return discount.
