In 2027, Social Security beneficiaries are expected to receive a 3.6% cost-of-living adjustment (COLA). Announced by the Social Security Administration (SSA) on October 14, 2026, this increase is intended to help benefits better keep pace with rising everyday costs.

The update affects an estimated 76 million people who receive Social Security or Supplemental Security Income (SSI). For retirees and others whose benefits help cover regular expenses, it is important to understand both the increase itself and the factors that may affect the amount ultimately deposited each month.

Medicare costs are one of those important factors. Because Medicare premiums can be withheld directly from Social Security payments, reviewing both updates together can provide a clearer picture of expected income and healthcare expenses for 2027.

What the 3.6% COLA May Mean for Your Benefits

Beginning in January 2027, monthly Social Security benefits will rise by 3.6%. This is an increase from the 2.8% COLA applied in 2026 and represents the largest Social Security benefit adjustment since 2023.

The SSA projects that the average retired worker will receive about $75 more per month, with the average monthly benefit rising from $2,095 to $2,170. Over a full year, that works out to roughly $900 in additional benefits for the average retiree.

SSI recipients will also receive the 3.6% adjustment. Their revised payments are scheduled to begin on December 31, 2026, ahead of the new calendar year.

The purpose of a COLA is to preserve purchasing power as the cost of necessities rises. Still, the specific increase each person receives depends on their current benefit amount, so individual results will vary.

How the Social Security COLA Is Calculated

The SSA determines the annual COLA by measuring changes in the cost of common goods and services, including food, transportation, and housing. Its calculation relies on an inflation measure known as the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W.

To establish the adjustment, the SSA compares CPI-W data from July through September with the same three-month period from the prior year. Based on that comparison, the 2027 Social Security cost-of-living adjustment was set at 3.6%.

Although this annual adjustment is designed to help benefits reflect inflation, it does not necessarily match every household’s actual cost increases. Healthcare and other essential expenses, in particular, may rise at a different pace.

Additional Social Security Updates for 2027

The COLA is not the only Social Security change for 2027. The SSA also announced updates that may matter to people who are working, nearing retirement, or receiving retirement or survivor benefits.

For 2027, the maximum amount of earnings subject to Social Security taxes will increase from $184,500 to $192,300. Earnings above that maximum are not subject to Social Security payroll taxes for the year.

The earnings limit also changes in 2027 for individuals who receive Social Security retirement or survivor benefits before reaching full retirement age. If you are below full retirement age for the entire year, the earnings limit will be $25,560.

If you will reach full retirement age during 2027, the earnings limit will be $67,920 for earnings received before the month you reach that age. After you reach full retirement age, there is no earnings limit.

Why Medicare Premiums Matter

A higher Social Security benefit does not always mean the full COLA amount will appear in your monthly payment. Medicare premiums can affect the net amount you receive.

Many beneficiaries have their Medicare Part B premiums deducted directly from their Social Security payments. If Part B premiums rise in 2027, the increase could reduce part of the additional benefit created by the COLA.

That is why it can be helpful to look beyond the stated percentage increase. Comparing your updated Social Security benefit with your Medicare costs can help you estimate the change in your available monthly income more accurately.
