The cost-of-living adjustment for Social Security - the raise that lands on about 71 million checks each January - is shaping up to be the largest in years, and the reason is not entirely good news. The estimate is climbing because inflation is [1][3].
The adjustment is set by inflation, specifically the CPI-W index measured over the third quarter. That gauge rose 4.4 percent over the year through May, its fastest pace since April 2023 [2]. As the readings have come in hot, the projections have moved up with them: the Senior Citizens League now estimates a 2027 raise of about 3.8 percent, and the analyst Mary Johnson has lifted her estimate to 4.7 percent - up from just 1.7 percent as recently as February [1].
Data
| 2025 | 2.5 annual COLA, % |
|---|---|
| 2026 | 2.8 annual COLA, % |
| 2027 (estimate) | 3.8 annual COLA, % |
A 3.8 percent adjustment would be the biggest since the 3.2 percent of 2024, and well above the 2.5 percent seniors received for 2025 and the 2.8 percent for 2026 [1]. Mary Johnson's 4.7 percent, if it held, would rank among the largest in more than three decades [1].
For a retiree, the number is a monthly reality, not an abstraction. A 3.8 percent raise works out to roughly 79 dollars more a month for the average beneficiary; the 2.8 percent adjustment for 2026 had already lifted the average check from about 2,015 dollars to 2,071 [1][3]. A bigger raise sounds like a gift, and in part it is. The mechanism that produces it is prices rising faster, so the extra dollars are chasing a higher cost of living rather than getting ahead of it.
The official figure will not be set until mid-October, when the third-quarter inflation data is complete [3]. What the current readings point to is a raise near the top of the range seniors have seen in a decade - a benefit increase that is also, read the other way, a measure of how much the cost of living has climbed [1][2].
