Put a working calculator on your site in one line
Do you run a blog, a construction or renovation forum, a financial-advice site, or any page where your readers ask practical questions like how many tiles do I need or what will my monthly payment be? You can now embed a compact, branded version of our calculators directly in your pages with a single <iframe> snippet — no registration, no API key, no JavaScript library to install.
Each widget keeps your visitors on your page: they type, they calculate, they stay. Every widget is available in English, Arabic (right-to-left), and Spanish, works on any device, and sets no cookies and collects no data — a good match for privacy-conscious audiences.

Copy any snippet below, or use the builder above. The suggested height keeps the whole calculator visible without inner scrolling; adjust it freely.
Why embed a calculator?
- Interactive content keeps readers on your page. A tool that answers a reader's question is stickier than a paragraph that answers it.
- Zero maintenance. The widget is served from our CDN; updates, bug fixes, and unit handling happen on our side and appear in your embed automatically.
- Privacy-friendly. The widgets load no cookies, no trackers, and no ad scripts inside the frame, so they are safe to use alongside strict privacy policies and consent tools.
- Mobile-ready. The layout adapts from 320 px phones up to desktop sidebars.
How to embed on common platforms
- WordPress: in the block editor add a "Custom HTML" block and paste the snippet. In the classic editor switch to the "Text" tab first.
- Blogger: in the post editor switch to "HTML view" and paste the snippet where the widget should appear.
- Ghost, Substack, Wix, Squarespace: use the platform's "embed" or "code" block and paste the snippet.
- Forums (Discourse, phpBB, vBulletin): support varies — Discourse allows iframes on trust level or per-site configuration; for phpBB, administrators can enable the [iframe] BBCode. When in doubt, link to the full calculator instead.
Frequently asked questions
Is it really free to embed these calculators?
Yes. Every widget is free for personal and commercial websites, with no registration and no API key. The only requirement is the small "Powered by SmartCalc Tools" credit, which is what keeps them free.
Do the widgets collect data from my visitors?
No. Widgets are static HTML and JavaScript: every calculation runs in the visitor's browser, nothing is sent to our servers, and the widgets set no cookies and load no analytics or advertising scripts.
Will embedding a widget slow down my page?
No. The iframe is lazy-loaded, and the widget itself is a few kilobytes of CSS and JavaScript with no external dependencies. Iframe sizing is fixed, so the widget cannot cause layout shift on your page.
Can I change the language of a widget?
Yes. Add ?lang=ar for Arabic (with full right-to-left layout) or ?lang=es for Spanish to the iframe URL. The default is English.
Can I customize the widget's colors or remove the credit?
The iframe is styleable from your own CSS like any other element. We ask that you keep the "Powered by SmartCalc Tools" credit visible — it is the only thing we ask in exchange for the free tool.
Can I embed several widgets on one page?
Yes, there is no limit. Each snippet is an independent iframe; mix and match any calculators.
