Early inflation data from July and August is pointing toward a notably stronger cost-of-living adjustment for Social Security recipients in 2027.
The Social Security Administration calculates annual COLAs using third-quarter changes to the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as the CPI-W.
When the CPI-W rises from one year to the next, benefits increase accordingly, and there is no mechanism for a negative COLA that would reduce monthly payments.
This year’s inflation surge, largely fueled by the Middle East conflict, has made the current 2.8% COLA look increasingly insufficient for millions of retirees.
A Motley Fool survey conducted after the 2.8% figure became official found that 54% of retirees said that level of increase was not going to be adequate.
Based on July and August CPI-W readings, several prominent analysts and advocacy groups are now projecting the 2027 COLA will land in the mid-3% range.
The Senior Citizens League projects a 3.5% COLA, independent Social Security analyst Mary Johnson also expects a 3.5% figure, and AARP is forecasting a 3.6% adjustment.
If any of those estimates prove accurate, the 2027 COLA would be the largest Social Security benefit increase since 2024, when recipients received a 3.2% raise.
For context, 2025 brought a 2.5% COLA, which was the smallest raise in five years, followed by this year’s modest 2.8% improvement.
September’s CPI-W data, which is the final piece needed to make the 2027 COLA official, is scheduled to be released on October 14.
If September inflation readings mirror those from July and August, beneficiaries could see their highest COLA in four years take effect at the start of 2027.
However, if inflation cools during the remainder of the third quarter, next year’s adjustment may fall short of surpassing 2024’s 3.2% raise.
Analysts caution that a larger COLA is not purely good news, since higher adjustments are always tied directly to rising prices that erode purchasing power in real time.
Anyone hoping for a COLA larger than 3.5% to 3.6% is, in effect, hoping for prices to surge further during the final weeks of September, which would squeeze household budgets.
Even after the official COLA number is announced in October, dual enrollees in Social Security and Medicare may not immediately know their true net benefit increase.
That is because Medicare Part B premiums are deducted from monthly Social Security payments, and the standard 2027 Part B premium may not be announced until November.
Until both figures are confirmed, some beneficiaries will be unable to calculate precisely how much their monthly checks will actually increase in the new year.
