CubedCalc

Embed a Free Construction Calculator on Your Website

Every calculator on this site can be dropped into your own page with two lines of HTML. It is free, needs no account, carries no advertising inside the frame, and works on any site that lets you paste HTML: WordPress, Squarespace, Wix, Shopify, a hand-built page, or a supplier's product page.

How to add one

Paste this where the calculator should appear, changing the slug to the one you want from the list below:

<div data-cubedcalc="concrete-calculator"></div>
<script async src="https://www.cubedcalc.com/embed.js"></script>

The script replaces the placeholder with the calculator and keeps its height in step with the result block, so there is no scrollbar inside the frame. It adds a one-line credit underneath ("Calculator by CubedCalc") that links back here. If you would rather not show it, add data-attribution="false" to the placeholder; the only thing we ask in return is that you do not present the tool as your own.

Who this is for

  • Ready-mix plants, lumber yards and landscape suppliers: customers arrive at the counter with the right quantity, and your product page answers the question that brought them.
  • Contractors and landscapers: an estimating tool on your site keeps a prospect on your page instead of sending them to a search engine.
  • Trade schools, extension offices and community groups: a worked tool to go with a lesson or a workshop handout.

What the embed does and does not do

  • The frame loads from cubedcalc.com, so updates to a calculator reach your page automatically.
  • Nothing a visitor types is sent to us or to anyone else; the arithmetic runs in their browser.
  • We measure how often each embedded calculator is used, with the same analytics as the main site, and nothing more.
  • The credit link is marked rel="nofollow" by default, because that is what search engines ask of widget links. Whether to change that on your own page is your decision.
  • No ads run inside the frame, now or later.
