Nothing to install
There is no plugin, app or extension to install. The snippet is the whole integration. Nothing is added to your Squarespace site, so there is nothing to update and nothing to conflict with.

Watch out
Code blocks require a paid Squarespace plan. On the free trial or a Personal plan without them, use the calculator's shareable link behind a button instead — it needs no code block at all.
Squarespace hides the block content while you are editing and shows a placeholder. Save and view the live page to see the calculator.
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 Code blocks work on every Squarespace plan?
No — they need a paid plan. If yours does not include them, put the calculator's shareable link behind a button instead. It works on any plan and needs no code.
Why does the block look empty in the editor?
Squarespace shows a placeholder for code blocks while editing. Save and view the live page and the calculator is there.
Will it match my site fonts and colours?
It can. Set the theme in the builder — colours, typeface, corner radius and spacing — so the calculator looks like part of the page rather than a box dropped onto it.
Can I put it in a blog post?
Yes. A Code block works in a blog post exactly as it does on a page.
