Fuel Cost Calculator
Calculate the fuel cost for a trip based on distance, fuel consumption rate, and petrol price.
Check your car's fuel economy sticker or owner's manual
Current price per litre of your fuel type
How It Works
Fuel cost = (distance / 100) x consumption rate x fuel price. The calculator also shows total litres needed, cost per kilometre, and for return trips doubles the distance. It provides comparison costs for different fuel types (petrol, diesel, LPG, EV) based on typical price ratios.
