Put a Kesoria calculator on your site
Add a free, interactive financial calculator to your blog or website with a single line of code. It is fast, respects your readers' privacy, and matches its own light or dark theme automatically - no signup, no tracking, no iframe.
How it works
Choose a calculator
Pick the calculator you want to embed. Set an optional starting currency to match your audience.
Copy the snippet
One line of script plus the calculator tag and a small credit link. No build step, no account.
Paste it in
Drop it into your page's HTML wherever you want the calculator to appear. That is the whole setup.
Try it
Configure the widget, copy the snippet, and see the exact result below.
Theme is automatic - the widget follows each reader's own light or dark system setting.
<script src="https://www.kesoria.com/embed/kesoria-embed.js" async></script>
<kesoria-calculator data-calc="networth" currency="USD"></kesoria-calculator>
<p><a href="https://www.kesoria.com/calculators/networth">Net Worth Calculator</a> by <a href="https://www.kesoria.com">Kesoria</a></p>This is exactly what your readers see and interact with on your site.
Why embed a Kesoria calculator?
Lightweight & fast
A tiny, dependency-free script - no heavy framework shipped to your readers, and no Core Web Vitals hit.
Isolated & safe
Renders in its own Shadow DOM, so your site's styles and the widget's styles never collide. No iframe, no scrollbars.
Light & dark, automatic
The widget follows each reader's own light or dark system preference, so it always fits in on your page.
Multi-currency ready
Set any starting currency with one attribute - built for an audience whose money crosses borders.
No signup, privacy-first
Free to use, no account or API key, and no tracking cookies or analytics inside the embedded widget.
A real backlink
A discreet, crawlable link back to the full calculator ships in the snippet - honest attribution search engines can see.
Want to share a specific scenario instead?
Every calculator on Kesoria has a built-in Share card - copy a link to your exact figures, or share it on LinkedIn, X, Facebook or by email, no login needed. The embed puts a live calculator on someone else's site; the Share card sends your own numbers.
More calculators are being made embeddable over time - each appears in the selector above automatically with the same one-line snippet.
