What Does This Tool Do?
You input the trip distance in miles, your car’s fuel efficiency (either MPG for US gallons or L/100 km for metric), and the current fuel price per US gallon. The tool calculates how many gallons you’ll need and the total cost in your currency. It’s useful for a single leg or a full road trip total. You can switch between MPG and L/100 km so it works for US and international travelers. No account or app download—everything runs in your browser.
How to Use It (Step-by-step)
- Enter the distance of your trip (or one leg) in miles.
- Enter your vehicle’s fuel efficiency and choose MPG (US) or L/100 km.
- Enter the current fuel price per US gallon (check local gas stations or a fuel app).
- Read “Estimated fuel needed” and “Estimated cost” in the result section.

FAQ
Check the manual, fuel economy label, or manufacturer website. Real-world efficiency can be lower; use your own average if you track fill-ups.
Convert price per liter to price per US gallon (1 US gallon ≈ 3.785 L) and enter that, or use a conversion tool first.
No. It only estimates fuel. Add tolls, parking, and maintenance separately for a full trip cost.
Yes. The calculator is free and runs in your browser.
