Overview
- Independent forecasters and advocacy groups currently estimate the 2027 cost‑of‑living adjustment will land in the mid‑3% range, roughly 3.1%–3.8%, which converts to about $60–$75 more per month on a typical $2,000 retired‑worker benefit.
- The Social Security Administration will set the official COLA after the Bureau of Labor Statistics publishes the September CPI‑W, and the announcement is expected on Oct. 14.
- Because the COLA is based on the average CPI‑W for July through September, a single hotter or cooler CPI‑W print in August or September can change the final percentage by tenths of a point.
- Administratively set costs that retirees pay—most importantly Medicare Part B premiums and the Income‑Related Monthly Adjustment Amount—plus fixed tax thresholds that make benefits taxable can reduce or eliminate much of the extra monthly cash from the COLA.
- Longer‑term pressure on the program continues: the Social Security trustees’ report projects a potential trust‑fund shortfall by about the fourth quarter of 2032, and other 2027 parameter changes such as higher earnings‑test limits and adjusted work‑credit amounts are projected but not yet official.
