Embed code
<iframe src="https://calcority.com/embed/break-even" width="100%" height="760" style="border:none;max-width:480px;" title="Break-Even Calculator — Calcority" loading="lazy" ></iframe>
Paste this anywhere in your site's HTML. The height above is sized for this calculator's field count — adjust it if your embed looks cropped or has extra space.
How it works
- Pick a calculator above and check the live preview.
- Copy the generated
<iframe>code. - Paste it into your site's HTML, a CMS embed block, or a client portal page.
- The calculator loads live from calcority.com — every visitor gets the current, accurate version.
Who embeds these
Accountants and fractional CFOs add a relevant calculator to a client-facing resource page instead of linking off-site. Bloggers and finance writers embed one inline in an article instead of describing a formula in prose. Other SaaS tools and agency sites add a calculator to a landing page as a lightweight, genuinely useful lead magnet that doesn't require building the math themselves.
Frequently asked questions
Yes. Every calculator on this page can be embedded on any website at no cost, with no account or API key required — just copy the code and paste it into your page.
Yes — the iframe always loads the live version of the calculator from calcority.com, so any accuracy fix or improvement on our end appears automatically on every site embedding it, with nothing for you to update.
Not currently — the attribution link is how this stays free to embed, and it's a small, unobtrusive line beneath the calculator rather than a banner or watermark over it.
The calculator keeps its own Calcority styling rather than inheriting your site's CSS, since an iframe is isolated from the parent page by design. It's built to look clean and neutral on light backgrounds, which covers most sites without any adjustment needed.
Yes — each embed is an independent iframe, so multiple calculators can sit on the same page without conflicting. Keep in mind each one adds its own load, so a page with many embeds will load a bit slower than one with a single embed.
