Tools that keep
their word.
We built mortgage-calculator.tools because most "free" calculators aren't. You find one, start using it, and then a popup appears asking you to sign up or pay to see the full results. That's not free — that's a trial.
Why we built this
Display advertising has funded free content on the internet since the beginning. We show ads. You get a genuinely free tool. No sign-up, no paywall, no catch.
Our promises
The Truly Free Seal
Every tool carrying this seal meets the same standard: no account, no paywall, no catch. We are building a network of tools that keep their word.
How we make money
This site is supported by advertising. That revenue covers server costs and keeps all tools free.
