Fuel Cost Calculator

Plan road-trip budgets with this fuel cost calculator. Enter the distance, your vehicle’s mileage in km per litre and the current fuel price.

How to use the Fuel Cost Calculator

  1. Pick the fuel type.
  2. Enter distance, mileage and price per litre.
  3. Read fuel required and total cost.

How it works

Formulas: Fuel needed = Distance ÷ Mileage; Cost = Fuel needed × Price per litre; Cost per km = Cost ÷ Distance.

Worked example

450 km at 15 km/L needs 30 L; at 100 per litre the trip costs 3,000.

Good to know

Real mileage changes with speed, traffic, load and air-conditioning use, so add a margin for long trips.
