Social Security benefits are projected to rise 3.5 percent in 2027, adding roughly $73 per month to the average retiree’s payment, according to estimates from AARP based on current inflation data. The official cost-of-living adjustment, or COLA, will be announced on October 14, 2026, and the increase will take effect with benefits paid in January 2027.
The projected 3.5 percent increase represents a significant boost compared to the 2.8 percent COLA beneficiaries received in 2026, and would mark the largest annual adjustment since 2023, when Social Security saw a record 8.7 percent increase, according to reporting from CBS News and Investopedia. The average retired worker’s monthly benefit would rise from approximately $2,086 to $2,159 under this projection.
Multiple forecasters have converged on similar figures as inflation data has cooled in recent months. The Senior Citizens League projects the 2027 COLA at 3.6 percent, while USA Today and other outlets report estimates in the 3.4 to 3.6 percent range. The final number will depend on September 2026 inflation data, which the Social Security Administration uses to calculate the adjustment.
The COLA mechanism itself is straightforward: it adjusts benefits annually to account for inflation, protecting recipients’ purchasing power. The adjustment applies to nearly 71 million Social Security beneficiaries and also affects Supplemental Security Income (SSI) recipients and certain federal retirees. Over a full year, a 3.5 percent increase would add approximately $876 to the average retiree’s annual income.
While the projected increase is welcome news for beneficiaries facing rising costs, the larger context matters. Recent COLAs have been volatile: after the 8.7 percent spike in 2023, the adjustments fell to 3.2 percent in 2024 and 2.5 percent in 2025 before settling at 2.8 percent in 2026. The 2027 projection suggests a return to more robust adjustments as inflation remains elevated, though still below the historic 2023 levels.
The 2027 COLA is one of several Social Security changes planned for 2027, including updates to earnings limits for beneficiaries under full retirement age and adjustments to the taxable maximum. Additionally, the full retirement age reaches 67 for those born in 1960 or later, reflecting ongoing demographic shifts in the program.
Beneficiaries can expect to receive official notification of the exact 2027 COLA increase in late November 2026, after the announcement on October 14. The timing gives recipients several weeks to adjust their budgets before the new benefit amounts arrive in January 2027 payments.
