Social Security’s cost-of-living adjustment for 2027 is projected to rise between 3.5% and 3.6% based on recent government inflation data. Announced estimates from AARP and policy analysts point to the highest annual adjustment in three years, though seniors face ongoing financial pressures from stubborn inflation.
The annual cost-of-living adjustment for the nation’s more than 70 million Social Security and Supplemental Security Income beneficiaries is tracking toward its highest increase in three years. Following consumer price index data released on Friday, September 11, 2026, advocacy groups and policy analysts have issued new forecasts placing the 2027 Social Security COLA in a range between 3.5% and 3.6%.
That prospective bump follows a 2.8% adjustment that went into effect for 2026 benefits, according to the Social Security Administration. While a 3.5% or 3.6% increase would outpace this year’s figures, advocacy leaders warn that fixed-income households continue to struggle against elevated living costs.
Competing Projections From AARP and The Senior Citizens League
Bureau of Labor Statistics. AARP raised its projection for the 2027 COLA to 3.6%, up from its 3.5% estimate a month prior.
The average monthly Social Security benefit for a retiree stood at about $2,086 in July, according to an AARP analysis. For surviving spouses, whose average monthly benefit sits at $1,933, a 3.6% adjustment would add about $70 a month. Social Security Disability Insurance recipients, averaging $1,635 monthly, would see an increase of about $59 a month.
Meanwhile, The Senior Citizens League projects a slightly more conservative 3.5% adjustment, down from its prior estimate of 3.6%. Independent policy analyst Mary Johnson also forecasts a 3.5% hike, factoring in the latest consumer price index data.
How the Bureau of Labor Statistics Calculates the COLA
The official adjustment is not determined by a single month of data. Instead, the Social Security Administration calculates the COLA by measuring the percentage increase in third-quarter inflation data from the prior year to the current year.
The formula relies on the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as the CPI-W. In August, the CPI-W increased 3.5% over the past 12 months, while the broader consumer price index rose 3.4%. Independent analysts note that one final month of data remains before the calculation is complete.
Mary Johnson, an independent Social Security and Medicare policy analyst, noted that the COLA calculation relies on third-quarter inflation data, with one final month of data still needed before the adjustment is determined.
The Bureau of Labor Statistics reported that the broader Consumer Price Index for All Urban Consumers rose 3.4% in August over the last 12 months, matching July’s pace. Monthly increases were driven largely by shelter, food, and energy costs, with gasoline rising 3.9% in August alone and accounting for over one-third of the monthly all-items increase.
Why Experts Warn Seniors Will Still Feel a Pinch
“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. The reality is that older Americans allocate their budgets differently than people still in the workforce, so inflation hits them differently. The CPI-W captures the experience of urban wage earners, which doesn’t represent the average senior’s budget.”

Economists also point to disparities in how different income groups absorb rising prices. Affluent households can absorb higher prices; lower- and middle-income households have far less room to adjust, wrote Diane Swonk, chief economist at KPMG US, in a report issued September 10.
Furthermore, the timing of the adjustment leaves a gap between rising expenses and relief. Benton noted that the COLA only happening once a year puts life on hold for a lot of seniors. When prices rise, they don’t rise next January when your benefit check goes up.
What to Watch Next on the October 14 Announcement Date
The exact figure for 2027 will remain unconfirmed until the release of the September Consumer Price Index data by the U.S. Bureau of Labor Statistics on October 14, 2026. The Social Security Administration will announce the official cost-of-living adjustment that same day.

Economists caution that volatile energy markets could influence final readings. Johnson noted that a lot depends on highly volatile oil prices, which are beyond my ability to forecast, so I leave this to others, or the betting markets to sort out for us. Diesel prices reaching record highs in September have also raised concerns among economists about secondary shipping and transportation costs trickling down to consumer goods before the final calculation is locked in.
