How it works
- Open the calculator you want and scroll to Add this calculator to your website.
- Press Copy embed code and paste it into your page's HTML (in WordPress, use a Custom HTML block; in Squarespace or Wix, an Embed or Code block).
- Publish. The calculator loads from SmartFinClub, so any fix or improvement we make appears on your page automatically.
The one condition: keep the credit
The calculators are free to embed as long as the short "by SmartFinClub" line under the calculator stays visible, unchanged and linked to SmartFinClub. Please don't edit the calculator, hide or crop its SmartFinClub name, or present it as your own work. The full terms are in Terms of Use, "Embedding our calculators".
What your visitors get, and what they don't
- No ads inside the embedded calculator, and no pop-ups or sign-up prompts.
- No cookies and no tracking of your visitors. The numbers they type stay in their browser.
- SmartFinClub records only the name of the website a calculator is embedded on and a view count, so we can see where the calculators are used. See the Privacy Policy.
- Every embedded calculator carries a short education-only note and links to our Financial Disclaimer. Embedding does not mean SmartFinClub endorses your business, and it does not make you our partner or agent.
Common questions
Does it cost anything? No. There is no fee, no account and no limit.
Will it slow my page down? The calculator loads lazily, when a visitor scrolls near it, so it doesn't delay the rest of your page.
Can I change the colors or default numbers? Not yet. If you'd like a version with your own defaults or branding, contact us.
The calculator looks cut off. Keep the small script that comes with the code; it resizes the calculator to fit. If your site strips scripts, increase the height value in the code instead.
