Calculate total fuel used and fuel cost for a trip from distance, consumption and fuel price, plus per-trip cost from tank size.
Mode 1 (Trip): enter distance (km), fuel consumption (L/100km) and fuel price (per L) to get total fuel used and total cost. Formula: cost = distance ÷ 100 × consumption × price. Mode 2 (Tank & one-way): enter tank volume (L), one-way distance (km), consumption and price to get one-way cost, one-way fuel, one-way/round trips per full tank, and range per tank. The currency is whatever unit your price uses. Results update live as you type.
