How it works

Two integration paths — pick the one that matches your CMS.

1

Pick a calculator

Scroll to the calculator you want below. Each one has a live preview so you can see exactly what your readers will see.

2

Copy a snippet

Click Copy. The simple snippet is a raw <iframe>. The auto-resize snippet adds a small loader script that eliminates scrollbars.

3

Paste & publish

Drop it into a Custom HTML block (Substack, WP Gutenberg, Ghost, Webflow, etc.) and publish. Calculator renders instantly.
