How to Calculate Fuel Cost for a Trip
Fuel cost depends on three factors: distance, your vehicle’s fuel efficiency, and the current fuel price. The formula is: Fuel Cost = (Distance ÷ 100) × Fuel Consumption (L/100km) × Price per Litre. This calculator supports km and miles, all efficiency formats (L/100km, km/L, MPG), and any currency.
Average Fuel Consumption by Vehicle Type
Small hatchback (Maruti Swift, Honda Fit): 5–7 L/100km | Sedan (Toyota Camry, Honda Accord): 7–9 L/100km | SUV/Crossover: 9–13 L/100km | Large SUV/Truck: 13–18 L/100km | Hybrid (Toyota Prius): 3–5 L/100km | Motorcycle: 2.5–4 L/100km
