How this calculator works
Enter the complete journey distance, the mileage your vehicle actually gives, and the current price per litre. The calculator divides distance by mileage to estimate litres required, then multiplies that figure by the fuel price.
Fuel required = Distance ÷ Mileage; Total cost = Fuel required × Fuel price
Use realistic inputs
For better estimates, use your vehicle's real-world figures and current local prices rather than only brochure claims.
