Formula: Fuel = Distance / Efficiency; Cost = Fuel * Price
Fuel Trip Cost Estimator
Estimate how much fuel you will need and what it will cost for a road trip. Enter the total distance, your vehicle fuel efficiency, and the current fuel price.
Formula
Fuel Needed = (Distance × Efficiency) ÷ 100. Total Cost = Fuel Needed × Price per Liter. Cost per km = Total Cost ÷ Distance.
Worked example
A 500 km trip in a car that uses 8 L/100km with fuel at 1.50 per liter: you need 40 liters of fuel, costing 60 total, at 0.12 per kilometer.
Practical guidance
Adjusting for real-world conditions
City driving, hills, heavy loads, and aggressive acceleration increase fuel consumption beyond the rated efficiency. Add 10-20% to your estimate for safety, especially for long trips in unfamiliar terrain.
Converting between fuel economy systems
If your car shows fuel economy in MPG rather than L/100km, use the built-in fuel economy converter first, then enter the equivalent L/100km value here. The calculator uses metric efficiency units.
