Free embeddable widget
Add a free retirement calculator to your article in 30 seconds
A polished, accurate 10,000-path Monte Carlo retirement calculator your readers can actually use — inside your post, on your domain. Copy one snippet, paste it where you want it, done. It’s lazy-loaded, collects no reader data, and carries a small attribution link back to Yearfold.

This is the real widget — try it. Your readers see exactly this.
Terms of embed
- Free to use on any site, commercial or personal.
- The “Powered by Yearfold” attribution link must remain visible and crawlable — it’s the only thing we ask in return.
- We may update or improve the widget over time; embeds pull the latest version automatically.
- The calculator is a financial-education tool, not investment advice. Results are probabilistic projections, provided without warranty. See the methodology and disclosures.
Questions publishers ask
Is it really free?
Yes. The widget is free to embed on any site, forever. We ask only that the small “Powered by Yearfold” link stays visible — that attribution is how the widget pays for itself.
Does it slow my page down?
No. The widget loads in a lazy iframe (loading=“lazy”), so it never blocks your page render and only loads when it scrolls near the viewport. The simulation runs in the reader's browser in a background Web Worker — nothing hits your server or ours until they click through.
Do you collect my readers' data?
No personal data is collected inside the widget — there's no email capture, no account, no tracking cookies. The reader's inputs stay in their browser. We record only anonymous, aggregate usage (that an embed loaded and was used) so we can tell which placements perform.
Can I match it to my brand?
Pick an accent color and a light or auto (dark-aware) theme above — the snippet updates as you choose. Colors are limited to an on-brand allowlist so the widget always stays readable.
