Social Security beneficiaries are tracking a 3.6% cost-of-living adjustment for 2027, the highest increase since 2023’s record 8.7% surge, according to the latest estimates released in August 2026. The estimate, calculated by the Senior Citizens League based on recent inflation data, represents a significant jump from the 2.8% COLA beneficiaries received in 2026.
The 3.6% figure translates to an estimated monthly increase of about $75 for the average retiree, raising the typical benefit from roughly $2,071 to approximately $2,146, according to projections from multiple sources tracking the adjustment.
Social Security’s cost-of-living adjustments are calculated automatically each year based on the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as the CPI-W. The Social Security Administration compares the average CPI-W for July, August, and September of one year to the same three-month period the year before, then applies that percentage increase to all benefits beginning in January of the following year.
The 2027 estimate has declined slightly from earlier forecasts made during the spring and early summer. In June, independent Social Security analyst Mary Johnson projected the 2027 COLA could reach 4.7%, but she revised that estimate downward to 3.6% in August after inflation data cooled, according to recent reports. The Senior Citizens League similarly lowered its projection from 3.8% in July to 3.6% in August as inflation moderated.
The 3.6% estimate, while notably higher than recent years, remains well below the 8.7% COLA that took effect in January 2023. That record adjustment followed decades of low inflation and came in response to the sharp price increases of 2021 and 2022. After 2023, the COLA declined to 3.2% in 2024 and 2.5% in 2025, reflecting cooling inflation.
The official 2027 COLA announcement is scheduled for October 14, 2026, when the Social Security Administration will release the final figure based on the third quarter’s inflation data. Until then, the October announcement will set the adjustment that takes effect in January 2027, and beneficiaries may see the estimate shift as new inflation reports are released in coming months.
For context, the 2027 COLA estimate has already dropped from higher projections earlier in the year, underscoring how sensitive the adjustment is to month-to-month inflation data. Projections have ranged from 3.4% to 3.6% as inflation cools, with most recent estimates clustering around the 3.6% figure.
