The calculator is a single self-contained block — no plugin to install, nothing to conflict with your theme. To add it to a page:

Edit the page and add a Custom HTML block.
Paste the calculator markup (the contents of embed.html).
Upload calculator.css and calculator.js, and point the two asset paths at them.
Publish — the calculator runs instantly, on desktop and mobile.

Its styles are namespaced under .roi-calc, so it adopts cleanly into your site without affecting anything around it. Colours are a small set of CSS variables — easy to match to your brand.

A demonstration build · the calculator runs entirely in the browser.
