Social Security Benefit Changes 2027: Expected COLA Increases and Full Retirement Age Guidelines

Social Security beneficiaries could see a larger increase in their monthly payments in 2027, with AARP projecting a 3.5% cost-of-living adjustment (COLA) as inflation points to a bigger increase than this year's 2.8% rise. The official COLA is expected to be announced on 14 October, after September inflation data are released.

If the 3.5% estimate holds, the increase would add about US$73 a month to the average retired worker's benefit, according to AARP. That would make the 2027 adjustment the largest since the 8.7% COLA introduced in 2023.

The expected increase comes alongside another issue facing retirees: the full retirement age is 67 for people born in 1960 or later, while the Old-Age and Survivors Insurance (OASI) Trust Fund is projected to deplete its reserves in the fourth quarter of 2032.

COLA Could Reach 3.5%

AARP's estimate puts the 2027 COLA at 3.5%, based on current inflation trends. The adjustment is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, with July, August and September readings used to determine the final increase.

The Senior Citizens League (TSCL), which tracks Social Security issues, has a higher 3.6% forecast. Both figures remain estimates until the Social Security Administration publishes the official calculation in October.

The final COLA is based on the average CPI-W for the third quarter compared with the average for the same period a year earlier. This means the September inflation reading will be the final piece of data needed for the government to calculate the 2027 adjustment.

A 3.5% COLA would raise the average retired worker's monthly payment by about US$73, according to AARP. The increase would be applied automatically, meaning Social Security recipients would not need to file a separate application to receive the adjustment.

The higher benefit amounts would take effect with payments issued in January 2027. The increase for each recipient would depend on their existing benefit amount and individual circumstances.

Retirement Age Stays at 67

The full retirement age is when a person becomes eligible for their full scheduled retirement benefit. Workers can claim Social Security retirement benefits as early as 62, but claiming before full retirement age results in a permanent reduction.

For people born in 1960 or later, the full retirement age is 67, according to the Social Security Administration. Benefits can also increase when a person delays claiming after full retirement age, up to age 70.

The retirement age is separate from Medicare eligibility, which generally begins at 65. Under current law, any change to the statutory retirement age would require congressional action rather than an automatic adjustment in 2027.

Trust Fund Faces 2032 Depletion

The longer-term issue is Social Security's financial position. The 2026 annual report from the programme's trustees projects that the OASI Trust Fund will deplete its reserves in the fourth quarter of 2032.

That does not mean Social Security payments would automatically stop at that point. The trustees project that continuing programme income would be sufficient to pay 78% of scheduled OASI benefits after the reserves are depleted.

The 2032 projection is therefore not a fixed deadline for the end of Social Security. It represents the point at which the trust fund's reserves are expected to be exhausted under the assumptions used by the trustees.

The trustees also project that the combined Social Security trust funds, covering retirement, survivors and disability benefits, would have reserves depleted in the third quarter of 2034. At that point, projected income would be sufficient to pay 83% of scheduled benefits.

Congress could change the programme's finances before either projected depletion date through measures such as tax increases, benefit changes or other reforms. Until lawmakers act, however, the projections highlight a potential gap between scheduled benefits and programme income after reserves are exhausted.

For retirees, the distinction matters. The 2027 COLA is a near-term adjustment expected to increase monthly payments, while the trust fund projections highlight a longer-term financing problem that could affect future benefit levels if lawmakers do not act.
