Embed the cost per person calculator
Put this free tool on your own website. Copy a snippet, paste it into any page or post. It works anywhere, no account needed, and a small "by Jupiter Signup" link sits under it.
Preview
Copy the embed code
Paste this where you want the tool to appear:
<iframe src="https://jupitersignup.com/embed/cost-per-person-calculator" title="Cost per person calculator" width="100%" height="540" style="border:0;max-width:620px" loading="lazy"></iframe>
Auto-resizing version
Add our tiny loader and the iframe grows to fit, so a result panel never gets a scrollbar:
<iframe data-jupiter-slug="cost-per-person-calculator" src="https://jupitersignup.com/embed/cost-per-person-calculator" title="Cost per person calculator" width="100%" height="540" style="border:0;max-width:620px" loading="lazy"></iframe> <script src="https://jupitersignup.com/static/embed.js" async></script>
