About this tool

plusbeauxjours builds small, free tools that answer one money question clearly, with sources.

What this tool does

The 2027 COLA Calculator estimates your January 2027 Social Security deposit after the cost-of-living adjustment and the Medicare Part B premium. The $90 rebate checker helps you see whether you likely qualify for the one-time Medicare Improvement Fund payment announced in October 2026.

How we work

• Every figure links to its source, with the date we checked it and whether it is official or projected.
• We update the numbers when SSA and CMS announce them and log each change on the FAQ & sources page.
• Calculations follow published Social Security rounding rules and run entirely in your browser.

What we are not

We are an independent publisher. We are not affiliated with or endorsed by the Social Security Administration, the Centers for Medicare & Medicaid Services, Medicare, the White House, or any government agency. Nothing here is financial, legal or tax advice. Your SSA notice is the authoritative figure for your benefit.
