The Social Security Administration will announce the 2027 cost-of-living adjustment (COLA) on October 14. Forecasters put the increase at 3.5%, which would turn a $2,000 monthly check into $2,070 starting in January. If the prediction holds, it will mark the sixth straight year of raises of at least 2.5% — something not seen since the 1990s.
The official figure drops at 8:30 a.m. Eastern on Wednesday, October 14, 2026, the same morning the Bureau of Labor Statistics releases September inflation data. The SSA will also announce the new taxable earnings maximum that morning. The increase takes effect with benefits paid in January 2027 (the December 2026 benefit); SSI recipients will see the new amount in the December 31, 2026 payment, since January 1 is a federal holiday.
The COLA isn't set by feel. It's the percentage increase in the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) for July, August and September 2026 over the Q3 2025 average of 317.265, rounded to the nearest tenth. Two of the three months are published: July at 327.104 and August at 328.481 — up 3.4% and 3.5% year over year, respectively. The math says a flat September yields 3.4%; a rise of at least 0.17% makes it 3.5%.
The Senior Citizens League (TSCL) trimmed its forecast from 3.6% to 3.5% on September 11; AARP still points to about 3.6%; independent Social Security and Medicare policy analyst Mary Johnson also lands at 3.5%.
On the average all-beneficiary check of $1,940.08 a month, 3.5% adds $67.90. On the average retired-worker's check of $2,085.98, it's about $73.01. A $1,200 benefit gains $42; a $3,000 benefit gains $105; the 2026 maximum at full retirement age ($4,018) gains $140.63. Under AARP's 3.6% call, the average increase would be about $75. All of these are gross amounts, before the Medicare Part B premium is deducted.
A 3.5% COLA would extend a remarkable run: 5.9% (2022), 8.7% (2023), 3.2% (2024), 2.5% (2025) and 2.8% (2026). The last time beneficiaries enjoyed six consecutive years of at least 2.5% was 1988 through 1997, when COLAs ran between 2.6% and 5.4%.
Two policy fingerprints are on this year's inflation. In July 2026, the Trump administration reinstated sweeping tariffs of 10% to 12.5% on more than 80 countries, lifting costs on imported goods. And the Iran war's seven-month closure of the Strait of Hormuz has sent crude and fuel prices soaring — visible every time drivers pass a gas station.
Bigger checks don't mean adequate checks. TSCL's 2026 Senior Survey found 89% of older Americans said the 2.8% COLA for 2026 was too low and that their checks were falling behind inflation; 44% of seniors draw all their income from Social Security. TSCL executive director Shannon Benton cautioned that an inflation surprise in the next 30 days could still move the final number up or down.
Medicare will also take a bite. The Medicare Trustees project the 2027 standard Part B premium at $209.50 a month, up $6.60 (3.25%) from $202.90 in 2026, with the final figure set by CMS in November. The hold-harmless rule keeps the Part B increase from exceeding the COLA in dollars for most beneficiaries — but part of the raise gets claimed by Medicare first.
Looming over the raise is the other countdown: per the 2026 Trustees Report, the Old-Age and Survivors Insurance trust fund runs dry in the fourth quarter of 2032, triggering an across-the-board benefit cut of around 22% if Congress doesn't act. Bigger checks and a solvent program are two sides of the same coin — October 14 reveals one number, but the harder test lies ahead.
