Free Embeddable Construction Calculators for Your Website

How it works

Copy the snippet for the calculator you want and paste it anywhere HTML is allowed — WordPress custom HTML blocks, Ghost, Webflow, plain sites. The widget is a lightweight static page (~25 KB) served from a global CDN, it loads lazily so it never slows your article, and every formula behind it is verified against published sources before any change goes live.

About the credit link

The small credit inside the widget is marked nofollow, so embedding a calculator will never affect your site's SEO in either direction. That is deliberate: Google asks that links inside distributed widgets don't pass ranking signals, because you didn't choose them editorially. Embed freely — there's no obligation and no catch.

If you genuinely find the tool useful and want to credit it properly in your own words, a normal link in your article text is welcome and is worth far more to us than anything automated:
