Run a contractor, landscaping or DIY website? Give your visitors a free concrete calculator. It works out how much concrete and how many bags any slab, patio or pad needs, in US or metric units, and it works on phones.

Paste it into your page where you want the calculator to appear. It works in WordPress (use a Custom HTML block), Squarespace, Wix and plain HTML sites.

Is it really free?
Yes. No sign-up, no fees and no ads inside the calculator. We only ask that you keep the small credit link underneath it.
