Formula
Convert distance and efficiency to fuel volume, then convert to the fuel-price unit. Fuel cost = fuel volume × unit price. Add entered whole-trip costs and divide by the number of people when splitting.
Worked example
A 500-km trip at 15 km/L needs about 33.33 liters. At 1.50 per liter it costs 50.00 in fuel; a round trip doubles the distance, while entered tolls/parking remain whole-trip amounts.
What the result means
Supports kilometers, miles, km/L, L/100 km, US and imperial MPG, matching fuel-price units, round trips, additional costs, and splitting. Actual efficiency and fuel price can vary.
