Nothing to install
There is no plugin, app or extension to install. The snippet is the whole integration. Nothing is added to your WordPress site, so there is nothing to update and nothing to conflict with.
WORDPRESS INTEGRATION
Add a calculator to WordPress
Paste one snippet into a Custom HTML block. That is the whole job — no plugin to install, no theme files to edit, and nothing that breaks the next time WordPress updates.

-
01
Build it
Start from a template or a blank canvas and add the questions, formulas and results you want.
-
02
Publish
Press Publish and copy the embed snippet.
-
03
Paste it into WordPress
Into an HTML block, as described above.
Where the snippet goes
- In the block editor, add a Custom HTML block and paste the snippet into it.
- In the classic editor, switch to the Text tab first.
Watch out
Do not paste it into the Visual tab. It escapes the tags and prints the snippet on the page as words — which is the commonest reason an embed "does not work" anywhere, not just on WordPress.
It works in page builders too: Elementor's HTML widget, Divi's Code module, Beaver Builder's HTML module, WPBakery's Raw HTML. All of them want the same snippet.
What you get
It fits the space it is given
The frame reports its height as the visitor moves through the calculator, so you never have to guess a height or leave a gap under it.
Republish and every copy updates
Change a price or a formula and every page you pasted it into shows the new version. You do not go back and edit those pages.
Or skip the embed entirely
Every calculator also has a full-page link of its own, so you can send it in an email or put it behind a button without embedding anything.
Questions
Do I need a plugin?
No. The snippet is ordinary HTML and WordPress has a block for that built in. Nothing is installed, so there is nothing to keep updated and nothing to conflict with your other plugins.
Will it work with my theme?
Yes. The calculator renders inside a frame with its own styling, so your theme cannot break it and it cannot break your theme. You set its colours and typeface in the builder to match.
Does it work with Elementor or Divi?
Yes. Use Elementor's HTML widget or Divi's Code module and paste the same snippet. Any builder with a raw-HTML block will do.
Will it slow my site down?
The calculator loads in its own frame after your page, so it does not hold up your content. Nothing is added to your WordPress install at all.
