Do I need a plugin?
No. A Custom HTML block or your builder's HTML element is enough.

Add a calculator to WordPress
To add a mortgage calculator to WordPress, paste your snippet into a Custom HTML block in the block editor, or into the HTML or code element of your page builder. No plugin is needed. The calculator renders in its own isolated container, so your theme's styles won't affect it.

Tips that save time
- Page builders such as Elementor, Divi or Beaver Builder have an HTML or Code element. Use that instead of a text widget.
- If a security plugin strips script tags, use the iframe snippet.
- Caching plugins may need a cache clear after you add the embed.
- Put the calculator under the price on listing posts, not at the very bottom.
Questions by topic
Questions agents ask
Does it work on WordPress.com?
Custom HTML with scripts requires a WordPress.com plan that allows custom code. On plans that don't, use a direct link button instead.
Can I use it in a widget area?
Yes. Add a Custom HTML widget to the sidebar or footer, or use a floating widget site-wide.
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.
