About Trip Tellers
Trip Tellers is a free website of travel calculators. It answers the practical questions of a trip: what the fuel will cost, how far and how long the drive is, how long the flight takes, and how much to tip.
We build each calculator on named sources, mostly official government data, and list them all on this page. Trip Tellers works in eight languages, needs no sign-up, and is built by its founder, Guy Yavetz, and a small team.
As of October 2026
The team
Why I started Trip Tellers
I started Trip Tellers in 2024 because I wanted to know what a trip abroad would really cost me, and I couldn't find tools that properly answered my questions: with real detail, with data that's updated regularly, and with numbers that are local to where I was going.
So I started building them, with one rule for every calculator: name the source, show the date, and put the math on the page.
Trip Tellers is still small and independent, which lets us fix things fast. If a number looks wrong to you, write to me. I read every message.
