Does my site need to allow third-party scripts?
For inline embeds, yes. Otherwise use the iframe snippet, which most CSPs allow with a frame-src entry.

Embed a calculator in any HTML page
To embed a calculator in HTML, paste one element and one script tag where you want it to appear. Any site or builder that accepts custom HTML can use it. If scripts aren't allowed, use the iframe snippet. If even that isn't allowed, link to the calculator's direct page.

Tips that save time
- Place the script once per page, even with several calculators.
- The script loads asynchronously, so it won't block your page.
- Use the popup button mode to save space.
- Set a Content Security Policy that allows the app origin if your site uses one.
Questions by topic
Questions agents ask
Can I style the calculator with my CSS?
Not from outside, by design, because isolation keeps it stable. Use the theme, colors and custom CSS settings in your dashboard.
Can I put it in an email?
No. Email clients block scripts. Use a direct link button instead.
The calculator doesn't appear. What should I check?
Make sure the whole snippet was pasted, including the script tag, and that you published or saved the page. Some builders only run scripts on the live site, not in the editor preview. If scripts aren't allowed, use the iframe snippet instead.
Can I change the calculator after embedding it?
Yes. Change defaults, theme, labels and the lead form in your dashboard. The snippet stays the same, and the live page updates.
Is embedding included on the free plan?
Yes. Every plan, including the free Agent plan, can embed calculators. Paid plans remove the credit and add webhooks.
How do I know leads are arriving?
Submit the calculator yourself on the live page. You'll get a new-lead email and see the contact in your account. On Team and Brokerage, check your webhook destination too.
