The terms, in short

  • It's free, for personal, school and commercial websites. No account or sign-up.
  • There are no ads inside the embedded calculator.
  • Please keep the small credit link to AllCalcHub under the calculator.
  • Calculations run in your visitor's browser, so their numbers aren't sent to us. When we improve a calculator, your copy updates automatically.
  • Results are estimates for general information, as described in our Terms of Use.

Questions

Can I change the size?

Yes. Change max-width in the code to make it narrower. The height fits the calculator automatically when the small script in the code is included; if your website doesn't allow scripts, keep the first two lines and the calculator uses a fixed height of 760 pixels.

Can I have a calculator that isn't listed, or a different colour?
