Fuel Cost Calculator
Calculate the total fuel cost of any trip — enter distance, efficiency, and fuel price for an instant estimate.
How the fuel cost calculator works
Enter your trip distance in kilometres, your vehicle's fuel efficiency, and the current local fuel price per litre. The calculator converts all efficiency formats (mpg, L/100km, and km/L) to a single litres-needed figure, then multiplies by your fuel price to give an instant cost estimate. Choose any currency from the selector so the result shows in the unit that matches your pump price.
All computation runs locally in your browser — no data is sent to any server. The mpg conversion uses US gallons (3.785 L) and statute miles (1.609 km).
FAQ
Can I enter distance in miles? Convert miles to kilometres first (multiply by 1.609), or switch the efficiency unit to mpg and the calculator handles the conversion internally.
Which gallon does mpg use? US gallons. UK mpg uses imperial gallons (4.546 L); to convert, multiply your UK mpg by 0.832 before entering it.
Is my data sent anywhere? No. Everything runs in your browser.
