About FuelTrip

FuelTrip is a small set of free calculators for estimating the fuel or charging cost of a drive — a daily commute, a cross-country road trip, or a carpool split. Every tool runs entirely in your browser, so you can plan a trip without creating an account or sending us any data.

We started FuelTrip after one too many back-of-envelope gas estimates on road-trip group chats. The goal is simple: type a distance and your car's efficiency, get a clear cost in seconds, and move on.

Editors review the formulas and the reference figures (typical MPG, unit conversions) so the numbers match standard engineering practice.
