Overview
- The Social Security cost‑of‑living adjustment for 2027 is set by changes in the CPI‑W measured over a three‑month window that begins in July and ends in September.
- Independent forecasters are publishing differing estimates for the likely COLA and no official increase has been announced yet.
- A projected 2.8% COLA would add roughly $56 to a $2,000 benefit but a Medicare Part B premium rise similar to last year’s $18 hike could erase a third or more of that increase.
- Beneficiaries should track July–September inflation readings and expect the Social Security Administration to announce the official COLA in October, with final net gains also shaped by Medicare premium decisions and policy choices.
- More than 71 million people rely on Social Security and a larger COLA could help restore lost buying power, but higher benefits can also raise long‑term financing pressures for the program.
