Frequently Asked Questions about Fuel Trip Calculator

Is the fuel trip calculator really free to use?

Yes, completely free. There are no hidden charges, no subscription plans, and no “pro” version that you need to unlock. You can access all features – basic calculation, vehicle comparison, and cost splitting – without paying a cent.

Does this calculator work offline after the page loads?

Once you’ve opened the page in your browser, all the code runs locally. You can disconnect from the internet and the calculator will still function. That’s because the tool uses client‑side JavaScript with no server calls.

Can I use MPG (US) instead of L/100km?

Absolutely. The fuel efficiency input has a dropdown that lets you choose between L/100km, MPG (US), and km/L. The fuel price unit also offers “$ per Liter” or “$ per Gallon.” The tool handles the conversion automatically.

How accurate is the fuel cost estimate?

It’s as accurate as the numbers you enter. The calculations use standard formulas with correct unit conversions. If you know your car’s real‑world fuel efficiency (not the manufacturer’s often‑optimistic number) and the exact fuel price, the result will be accurate within a few cents.

Is my trip data stored anywhere?

No. The calculator does not send any data to a server. Your distance, efficiency, price, and results remain on your device. When you close the tab, everything is gone. This is a great feature for anyone concerned about data privacy.

Can I compare more than two vehicles?

The current version supports a direct comparison of two vehicles. If you need to compare three or more, you can do repeated comparisons manually by noting the results. The team might add more vehicles in future updates.
