“Stingy. Inadequate. Unfair.” These are just some of the words seniors most likely used to describe their 2026 Social Security cost-of-living adjustment, or COLA. Given that this year’s raise came in at just 2.8%, that frustration is understandable.
Social Security recipients enjoyed a couple of large COLAs in the wake of the pandemic, but in recent years those raises have been meager. The 2025 COLA was just 2.5%, and the 2026 bump of 2.8% barely kept pace with inflation, making it harder for the program’s more than 75 million beneficiaries to cover rising costs.
But 2027 is shaping up differently. Experts broadly agree that next year’s Social Security COLA could be the largest in several years. Whether that’s actually good news is a more complicated question.
What the experts predict for 2027’s Social Security COLA
The official COLA won’t be locked in until October, when the Social Security Administration releases its announcement based on third-quarter inflation data. Independent forecasters can use available Consumer Price Index readings to make educated early estimates, and the picture has shifted considerably since spring.
Projections climbed sharply in the spring of 2026. The CPI for Urban Wage Earners and Clerical Workers (CPI-W), the index the SSA uses to calculate the COLA, rose 0.7% in May alone, pushing its year-over-year gain to 4.4%, the fastest pace since April 2023. That surge prompted independent Social Security and Medicare analyst Mary Johnson to raise her 2027 COLA forecast to 4.7%, up from the 4.2% she had projected the prior month.
June’s inflation data changed the calculus. Annual CPI growth cooled to 3.5%, driven by the largest drop in consumer energy prices in over six years, and Johnson cut her estimate by a full percentage point to 3.7%. Then July CPI data, released on August 12, 2026, pulled estimates down again. Johnson lowered her forecast to 3.4%, noting that “a moderation in inflation has resulted in bringing down my estimate from higher peaks earlier this year.” The nonpartisan Senior Citizens League (TSCL) also revised its estimate downward, to 3.6% from 3.8%. AARP, using Federal Reserve inflation projections for the remaining measurement months, released its own estimate of 3.5%.
The current consensus range sits between 3.4% and 3.6%, still well above 2026’s 2.8% COLA. Johnson noted that even her lower estimate remains above the long-term average COLA of around 2.6%, and the SSA has cited a 10-year historical average of 3.1%. If TSCL’s 3.6% projection holds, average monthly retirement benefits would rise by roughly $70, climbing from the base figure of $1,937.53 used in TSCL’s model to approximately $2,007. AARP estimates that its 3.5% projection would add about $73 per month to the average retired worker’s check. Forecasts at this stage can still shift materially, however. Only one of the three measurement months (July, August, and September) has been reported, and every new CPI-W reading will move the needle.
Why seniors shouldn’t celebrate a large Social Security COLA
A COLA in the 3.4% to 3.6% range might sound like a meaningful win after two consecutive years of raises below 3%. But the core reality of how COLAs work tempers any enthusiasm.
Social Security COLAs are fundamentally different from merit-based raises in the working world. A high-performing employee might earn a raise that genuinely improves their standard of living. A COLA does no such thing. It is calibrated to match inflation, not to outpace it. At best, a generous COLA allows retirees to tread water financially, holding their purchasing power roughly steady.
If the 2027 COLA comes in near the top of current projections, it will reflect elevated inflation through the summer months. Seniors may welcome the larger benefit check in January 2027, but they will have spent the months leading up to it paying more for groceries, housing, and health care. The Medicare factor compounds this dynamic. According to the 2026 Medicare Trustees Report, the standard Part B premium is projected to rise to approximately $209.50 per month in 2027, up from $202.90 in 2026. Because Part B premiums are automatically deducted from Social Security checks, that $6.60 monthly increase will offset a portion of whatever COLA boost retirees receive.
There is also a longer-term mismatch worth flagging. Over the three years from 2024 through 2026, Medicare’s Part B premium rose 5.9%, 5.9%, and 9.7% in succession. Over those same years, the Social Security COLA came in at 3.2%, 2.5%, and 2.8%. Health care costs, in other words, have consistently outpaced the adjustment meant to cover them.
Don’t misunderstand what COLAs are meant to do
For current and future retirees, the broader lesson from every COLA cycle is the same: Social Security benefits alone are a shaky foundation for financial security in retirement. COLAs are a stabilizer, not a growth engine.
The best long-term defense against inflation is supplemental income from savings and investments. A diversified stock portfolio has historically generated returns that outpace inflation over time, even if it comes with volatility along the way. Bonds offer a different tradeoff: they provide predictable income and can serve as a cushion when equity markets fluctuate, even if their real returns are modest.
Congress reintroduced the Social Security 2100 Act in July 2026, a bill that would, among other provisions, shift the COLA calculation from the CPI-W to the Consumer Price Index for the Elderly (CPI-E). Proponents argue the CPI-W is a poor fit for retirees because it is weighted toward spending habits of younger working adults, giving more weight to gasoline and electronics while underweighting housing and medical expenses. Whether the legislation advances is uncertain, but it reflects growing pressure to reform a COLA formula that many advocates say consistently falls short.
The SSA will make its official 2027 COLA announcement in October, once September inflation data is in. Between now and then, every monthly CPI-W release has the potential to move projections in either direction. A higher COLA would still be worth something. But it will only arrive after months of elevated prices, and it still won’t help retirees pull ahead.
Editor’s note: This article was updated to reflect August 2026 COLA projections, including Mary Johnson’s revised estimate of 3.4%, TSCL’s updated forecast of 3.6% (down from 3.8%), and AARP’s new estimate of 3.5%, all based on the July 2026 CPI-W data released on August 12, 2026. The projected monthly benefit increase figures were also updated to reflect TSCL’s and AARP’s current models.
