Free, no signup, no API keys. Copy one of the snippets below and paste it into any HTML page, blog post, or CMS block (WordPress, Webflow, Ghost, Squarespace, etc.).

Standard embed (fixed size)

Drop this into a blog post or HTML block. Works in WordPress, Ghost, Webflow, Notion, Substack — anywhere that allows raw HTML.

<iframe
  src="https://findtdee.com/embed"
  width="500"
  height="700"
  frameborder="0"
  style="border:0; max-width:100%;"
  title="TDEE Calculator by FindTDEE"
  loading="lazy"
></iframe>

Responsive embed (mobile-friendly)

For sites where width matters more than fixed dimensions. The aspect-ratio wrapper keeps it readable on phones.

  <iframe
    src="https://findtdee.com/embed"

    title="TDEE Calculator by FindTDEE"
    loading="lazy"
  ></iframe>
</div>
