What the widget shows
- The visitor's IRMAA tier for 2026 (official CMS figures) or 2027 (Projected until CMS posts the official table).
- Part B and Part D amounts per person per month, and the extra cost per year.
- The income room left before the next cliff, and how far over the last line they are.
- A dated source line. Education only; nothing is sold.
Fresh, dated numbers
The figures come from the Foundation's checked number registry and carry an as-of date inside the widget. The official 2027 table is expected in mid-November 2026; embedded copies switch over on the same day. The source table is on our 2027 IRMAA brackets page.
If you cite our data
The credit line inside the widget is a plain, unstyled link. If your article or resource page also quotes the numbers, an in-text citation to the data page helps your readers find the full table. Ready to paste:
Questions
Is the widget really free?
Yes. There is no fee, no account and no tracking cookie. The only requirement is that the visible credit line in the widget stays in place.
Do my visitors have to give an email address?
No. The result is fully visible. A link under it leads to the Foundation's longer IRMAA calculator.
How do the numbers stay current?
The widget reads a small data file from the Foundation's server each time it loads. When CMS posts the official 2027 figures in mid-November 2026 the file is updated and every embedded copy updates with it. The as-of date is shown in the widget.
Can I match my site's colors?
Yes. Add data-accent with a six-digit hex color and data-theme set to light, dark or auto. The credit line cannot be removed.
What does the optional email box do?
It is off unless you add data-lead="1". When on, a visitor can ask for the Foundation's free one-page 2026 numbers sheet by email. The address goes to the Foundation, never to your site, and it is not sold.
