The Trip Fuel Cost Calculator estimates how much fuel a journey will use and what it will cost, based on the trip distance, your vehicle mileage and the current fuel price.
Litres needed = Distance Γ· Mileage; Cost = Litres Γ Fuel price.
A 300 km trip at 15 km/L with fuel at 100/L uses 20 litres and costs 2,000.
