2027 COLA Seen at 3.5%-3.6%, Highest Since 8.7% Spike 4 Years Ago

Q: Will rising Medicare premiums and hidden healthcare costs instantly swallow the largest Social Security boost in four years?

Not instantly for most retirees, but the gain is likely to be noticeably smaller once Medicare and other medical bills are counted. At the projected 3.5% Social Security COLA for 2027, the average monthly benefit would rise by about $68, from roughly $1,942 to about $2,010. By contrast, the best current estimate for the standard Medicare Part B premium is about $209.50, up from $202.90 in 2026, or roughly $6.60 more a month. Even if private forecasts closer to $216 to $219 prove right, the premium increase alone would still absorb only part of the average COLA, not all of it. The bigger problem is that Part B is only one piece of retiree healthcare spending. Part B deductibles are projected to rise, and 2027 already brings confirmed increases in Part D costs, including a higher deductible and a higher out-of-pocket cap. Higher-income beneficiaries may also face IRMAA surcharges, which can wipe out much more of the raise. Beyond Medicare premiums, seniors often face dental, vision, hearing, copays, coinsurance and other costs that Medicare does not fully cover. That is why advocates say the boost may feel weaker than the headline number suggests. Social Security COLAs are tied to CPI-W, which many analysts say does not reflect older Americans’ spending patterns well, especially for healthcare and housing. So the largest COLA in four years is likely to leave most retirees with some net increase, but for many it will not feel like a full raise once medical costs are deducted.

Latest estimates put the 2027 cost-of-living adjustment for Social Security, VA disability and military retirement benefits at 3.5% to 3.6%, above this year’s 2.8% increase.
CPI-W readings have run above year-ago levels since March, and the final September 2026 inflation figure due Oct. 14 will set the official adjustment.
If confirmed, the increase would be the biggest since the pandemic-era jumps of 8.7% and 5.9%, and otherwise the highest since 2012’s 3.6% rise.
Higher COLAs lift monthly checks but also reflect price pressures that may still outpace beneficiaries’ costs, especially for retirees and disabled veterans.
The larger projection could also revive deficit-cutting proposals in the new Congress, including a CBO-backed COLA formula change once estimated to save $278 billion over 10 years.
