The American Association of Retired Persons forecasts a 3.6% Social Security cost-of-living adjustment for 2027, which would mark the largest annual increase since 2023 when beneficiaries received a 8.7% boost. The projection reflects AARP's analysis of inflation trends and wage growth data that feed into the formula the Social Security Administration uses each October to calculate the following year's COLA.
Social Security recipients depend on the COLA to maintain purchasing power as inflation erodes the value of fixed income. The 3.6% adjustment would translate into meaningful dollars for the roughly 67 million Americans collecting Social Security benefits. For example, a retiree currently receiving the average monthly benefit of $1,907 would see an additional $69 per month under AARP's 2027 projection, adding roughly $828 annually.
The forecast assumes inflation moderates from current levels but remains elevated relative to the Federal Reserve's 2% long-term target. The COLA calculation relies on the average Consumer Price Index for Urban Wage Earners and Clerical Workers from July, August, and September of the year before the adjustment takes effect. If inflation persists above expectations or wage growth accelerates, the actual 2027 COLA could exceed AARP's estimate. Conversely, disinflation could push the adjustment lower.
Context matters here. The 2023 COLA of 8.7% represented the largest increase in four decades, reflecting the inflation spike that followed pandemic-era fiscal stimulus and supply chain disruptions. The 2024 COLA settled at 3.2%, and 2025 figures show a 2.5% adjustment. AARP's 3.6% projection for 2027 sits between recent years, suggesting a normalization of inflation after the extraordinary 2022-2023 period.
Policymakers, benefit recipients, and financial planners monitor COLA projections closely. Higher COLAs boost government spending on Social Security, which consumed 5.3% of federal revenues in 2024 and faces long-term solvency challenges. The Social Security trust funds are projected to exhaust reserves by 2033, after which the program would collect only enough payroll taxes to pay roughly 80% of scheduled benefits without legislative action.
For retirees and near-retirees, COLA forecasts inform retirement income planning. Those living primarily on Social Security and investment portfolio withdrawals factor COLA projections into spending assumptions. Financial advisors use these estimates when stress-testing retirement plans against various inflation scenarios.
The AARP projection also carries political weight. Congress has debated various Social Security reform proposals, from raising the payroll tax cap to gradually increasing the full retirement age. Discussions around program sustainability often reference benefit adjustments and their fiscal impact.
Investors should watch the inflation data released from July through September 2026, as those monthly CPI reports will determine the actual 2027 COLA calculation. Higher-than-expected inflation during that period would push the adjustment above AARP's 3.6% forecast, while softer inflation would move it lower.
