FOR PUBLISHERS AND COACHES

Embed our calculators free

Ten free calculators you can drop into any website, blog or client project. Copy one line of code, keep the attribution link, done.

Every GramGoal calculator can be embedded free on your own site. The tools are responsive, load in about 30 KB, and resize themselves to fit your layout. No signup, no API key, no tracking of your visitors beyond standard analytics.

The only condition: keep the attribution link at the bottom of the widget intact. That is what makes this free.

How to embed

Pick a calculator below and copy its code.
Paste it into your page wherever you want the tool to appear. In WordPress use a Custom HTML block; in Squarespace, Wix or Webflow use an embed or code element.
The widget will size itself automatically. If your platform blocks scripts, the iframe still works at the fixed height.

Questions

Is it really free? Yes, for any site, commercial or not, as long as the attribution link stays.

Will it slow my page down? The iframe loads lazily and the widget is roughly 30 KB. It will not block your page rendering.

Can I restyle it? Not directly, since it renders on our domain. If you need custom colours for a client project, contact us and we will look at it.

Do you track my visitors? Standard analytics on our side only. No cookies are set on your domain by the widget.
