Why CalcStack
Why CalcStack for Notion?
Turn a doc into a lead surface
A public Notion page is usually read-only: someone reads it and leaves. Embedding a calculator gives the reader a reason to act inside the page, and the result they generate becomes a lead with full context instead of an anonymous pageview.
Works on Notion sites
If you publish with Super, Potion, or Notion's own public sharing, the embedded tool renders for every visitor exactly as it does in the editor. Your Notion-built landing page or knowledge base captures leads without leaving Notion.
Native block, no code
CalcStack uses Notion's built-in embed block, so there is nothing to install and nothing to maintain. The tool lives on CalcStack and you only paste a URL; the block behaves like any other piece of Notion content.
How the Notion Embed Works
Notion started as a document and wiki tool, but it has quietly become a publishing platform: teams ship public roadmaps, creators run sites on Super and Potion, and consultants share pitch pages as Notion links. The catch is that a Notion page is almost always read-only. A visitor scrolls, learns something, and leaves with no way for you to know who they were. An embedded interactive tool fixes that. The reader enters their own numbers, sees a result that applies to them, and in the same step becomes a lead you can follow up with.
According to Notion's published figures, the platform surpassed 100 million users in 2024, and a growing share of those users publish pages to the public web rather than keeping them private. That makes Notion a real distribution surface, not just an internal one. A single CalcStack calculator or assessment placed in a public Notion page or a Notion-built site does what the page alone never could: it turns a passive read into a captured lead, using nothing more than the embed block Notion already ships.
Embed Code Reference
Notion does not take raw HTML; it takes a URL in an embed block. Paste the CalcStack embed URL below into a /embed block on your page.
Embed URL (paste into a /embed block)
https://calcstack.net/embed/saas-roi-calculator?customer=your-idFor sites that accept raw HTML (Super custom code)
<iframe src="https://calcstack.net/embed/saas-roi-calculator?customer=your-id" width="100%" height="750" frameborder="0" style="border:none;border-radius:12px;"></iframe>Find your Customer ID in your CalcStack dashboard under Settings. Without it the tool runs as a branded demo with no lead capture. Browse every tool you can drop into a Notion page on the resources page.
Common Issues & Troubleshooting
Notion embeds are dependable once the page is shared correctly. These are the two snags Notion users hit most.
The tool shows for me but not for visitors
Cause: The page is still private. An embed block only renders for people who can open the page, so an unshared page hides the tool from everyone but you.
Fix: Open Share in the top right, enable Share to web (or share to your workspace), and confirm the link is live. The embedded tool then renders for every visitor who opens the public page or your Super or Potion site.
The embed is too short and scrolls inside itself
Cause: Notion gives a new embed block a small default height, so a multi-step calculator gets a scrollbar inside the block.
Fix: Hover the block and drag the bottom handle down to 650 to 800px. The tool is responsive inside the frame, so once the block is tall enough the full flow shows without an inner scroll.
