Embed our calculators on your site
All 15 calculators below are free to embed on any website — a blog, a client resource page, an internal wiki. Paste one line of HTML and you're done.
- · Auto-resizing — the widget measures itself and tells your page how tall to be, so nothing clips or leaves dead space.
- · No signup, no tracking pixels, no ads inside the widget.
- · Mobile responsive — give it the full width of your content column and it adapts.
- · Built for India — INR, current FY 2025-26 tax slabs, Indian products and rules.
The only condition: keep the one-line attribution below the widget. That's how people find us, and it's the whole reason these are free.

Can I change the height?
Yes, but you shouldn't need to. The height in the snippet is a starting value; the widget corrects it as soon as it loads and whenever it resizes.
Can I restyle it to match my site?
Not directly — it's an iframe, so your CSS can't reach inside. You can change the border and corner radius on the iframe itself. If you need something specific, get in touch.
Will it slow my page down?
The snippet uses loading="lazy", so the widget only loads when a reader scrolls near it. Nothing is fetched before that.
Do you collect data on my readers?
No. Calculations run entirely in the browser. Nothing your readers type is sent anywhere.
Is it really free?
Yes, with no catch and no expiry. Keep the attribution line and use it as long as you like.
