AARP Projects 3.6% Social Security COLA for 2027 Following August CPI Release

The official 2027 Social Security cost-of-living adjustment depends entirely on third-quarter inflation data, and the latest figures indicate that the condition for a substantial increase is currently holding. Following the release of the August Consumer Price Index, which showed inflation running hotter than anticipated, AARP has updated its projection for next year's benefit bump to 3.6%. That figure represents a slight upward revision from the organization's 3.5% estimate in August and sets the stage for what could be the largest adjustment since the 8.7% surge implemented in 2023.[1][2]

The U.S. Bureau of Labor Statistics reported on September 11, 2026, that the Consumer Price Index for All Urban Consumers (CPI-U) increased 0.4% on a seasonally adjusted basis in August, pushing the 12-month inflation rate to 3.4%. The subset index used specifically to calculate Social Security COLAs—the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W)—rose 3.5% year-over-year. Energy costs were a primary driver of the August increase, with the gasoline index rising 3.9% and accounting for more than a third of the overall monthly jump.[2][5]

If the 3.6% projection holds through the final month of the calculation window, the financial impact for beneficiaries will be tangible. The average retired worker, who received approximately $2,086 a month as of July 2026, would see their monthly benefit increase by roughly $75, pushing the average check to nearly $2,161 at the start of 2027. Surviving spouses would see an average increase of about $70, while the average Social Security Disability Insurance recipient would receive an additional $59 per month.[1][2]

The trajectory of the 2027 COLA has shifted alongside the volatile inflation data of the past few months. Earlier in the summer, cooling price pressures had led some analysts to predict a smaller adjustment. However, the August data reversed that trend. AARP noted that older Americans are feeling the sting of inflation most acutely in non-discretionary categories like groceries, energy, housing, and healthcare. Because retirees on fixed incomes allocate a larger percentage of their budgets to these essential categories than younger workers do, headline inflation numbers often understate the actual financial pressure they experience.[1][2][4]

Other advocacy groups are tracking slightly different numbers, though all point to an increase that outpaces the 2.8% adjustment implemented for 2026 and the 2.5% bump in 2025. The Senior Citizens League, a nonpartisan group that advocates for older Americans, recently revised its own forecast down slightly to 3.5%, citing the complex interplay of short-term economic shocks. "No matter if the COLA announcement comes in slightly higher or slightly lower than our prediction, seniors will probably end up disappointed in the long run," said Shannon Benton, executive director of the Senior Citizens League. "The reality is that older Americans allocate their budgets differently than people still in the workforce, so inflation hits them differently."[1][3]

The structural mechanics of the COLA calculation mean that the final number remains locked until the fall. The Social Security Administration averages the CPI-W readings for July, August, and September, and compares that third-quarter average to the same period from the previous year. With two of the three months now on the books, the final variable is the September inflation report.[2][3][5]

The reliance on the CPI-W has long been a point of contention among advocates for older Americans. The index tracks the spending habits of urban wage earners and clerical workers, a demographic that typically spends less on out-of-pocket healthcare and more on transportation than retirees do. Critics argue that this mismatch structurally shortchanges seniors, as medical care costs tend to rise faster than broader inflation measures.[1][2]

The official 2027 cost-of-living adjustment will be formally announced by the Social Security Administration on October 14, 2026, shortly after the Bureau of Labor Statistics releases the September CPI data. Until then, beneficiaries and financial planners are using the 3.5% to 3.6% range as the baseline for 2027 household budgeting, watching closely to see if energy markets or housing costs introduce any final volatility into the September figures.[1][3]
