Social Security’s 2027 raise is still two months from being official, but the early math is pointing toward the largest increase beneficiaries have seen since 2023. The Senior Citizens League, a nonpartisan advocacy group that tracks inflation data monthly, now projects a 3.6% cost-of-living adjustment for next year. Nothing about that number is locked in, but for a household counting on a Social Security check to cover rent, groceries and medication, even a preliminary estimate is worth understanding before the real figure lands in the fall.
A Projection Built on July’s Inflation Report, Not a Government Decision
The 3.6% figure comes from The Senior Citizens League’s statistical model, which factors in the Consumer Price Index for Urban Wage Earners and Clerical Workers, Federal Reserve interest rates and the national unemployment rate. In its August 12 release, the group said July’s CPI-W came in at 3.4%, and its model expects inflation to tick up slightly over the following two months, landing the annual adjustment near 3.6%. That would be 0.8 percentage points above this year’s 2.8% raise and the biggest jump since the 8.7% adjustment that followed the 2022 inflation surge.
Crucially, this is an outside group’s forecast, not a Social Security Administration determination. The agency itself has published no 2027 figure. The Senior Citizens League’s own estimate has already moved once this cycle, sliding from 3.8% projected in July to 3.6% in August as inflation cooled slightly month over month.

Why the Official Number Won’t Arrive Until October 14
By law, the Social Security Administration calculates the annual COLA using the average CPI-W reading across July, August and September, compared with the same three months in the prior year. Only one of those three months, July, has been reported as of early September. August’s inflation data is not due out until mid-September, and September’s figure follows roughly a month later. The Social Security Administration confirms that the agency announces the finalized adjustment each October, and this year’s announcement is expected October 14. Until then, any percentage in circulation, including the 3.6% figure, is an estimate built on incomplete data.
A Competing Estimate Lands Close, But Not Identical
The Senior Citizens League is not the only group modeling next year’s adjustment. AARP, the advocacy organization for people 50 and older, published its own projection the same week, putting the 2027 COLA at 3.5%, a tenth of a point below The Senior Citizens League’s estimate. The two estimates rely on similar inflation data but different modeling assumptions, and both organizations have said they will keep updating their projections as the remaining CPI-W reports are released. The fact that two respected, independent models arrived within a tenth of a point of each other is one reason 3.6% is treated as a credible planning estimate, even though it carries no legal weight until the Social Security Administration itself makes the call.
What a 3.6% Adjustment Would Mean in Dollar Terms
The average retired worker collected $2,071 a month in Social Security benefits as of January 2026, according to Social Security Administration data cited in the CBS News reporting on the projection. Applying a 3.6% increase to that baseline would raise the average monthly check by roughly $75, to about $2,146. That estimate moves with the benefit amount: a retiree currently drawing $1,600 a month would see closer to a $58 increase, while someone drawing $3,000 would see about $108 more. None of these figures are final, and the eventual adjustment could land a few tenths of a point higher or lower once August and September inflation data are folded in.
The Recurring Complaint: A Raise That Arrives After the Bills Do
Even when the COLA lands close to its projection, many retirees say it still falls short of what they actually spend. The Senior Citizens League’s own survey work found that a large majority of beneficiaries felt the 2.8% adjustment that took effect this January failed to keep pace with real-world costs at the grocery store, the pharmacy and the insurance renewal notice. That frustration stems from how the COLA is built: it reacts to inflation that has already happened over the prior three months, rather than protecting purchasing power in real time. A 3.6% raise, if it holds, would be the largest adjustment in four years, but it would still be calculated off data that is, by the time it reaches a beneficiary’s check in January, several months old. Retirees budgeting around next year’s benefit increase are better served treating 3.6% as a reasonable planning range rather than a number to build a fixed budget around until the Social Security Administration’s October announcement makes it official.
