Social Security Announces 2027 COLA: 3.6% Increase Starting in January (What It Means for Your Medicare)

Social Security announced a 3.6% cost-of-living adjustment for 2027 on October 14, 2026. The Social Security 2027 COLA is the largest annual increase since the 8.7% adjustment in 2023. It affects more than 75 million people receiving Social Security, adding roughly $75 to the average monthly benefit, to about $2,170-starting in January 2027. Around 7.3 million SSI recipients will see their increase beginning with the December 31, 2026 payment.

For people on Medicare, however, the headline isn’t the whole story. The increase is a gross benefit adjustment; Medicare premiums and other costs can affect what remains in your budget. With the Medicare Annual Enrollment Period starting tomorrow, October 15, this is a timely moment to review both your income and your coverage for 2027.

What the 2027 Social Security COLA means

A cost-of-living adjustment is intended to help benefits keep pace with inflation. It is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), comparing average July-through-September figures with the comparable period used for the previous adjustment. The September inflation rate of 3.7% is relevant context, but the COLA is based on the CPI-W calculation, not simply September’s annual inflation figure.

The Social Security increase in January 2027 will vary by person because it is calculated from each person’s benefit. For an individual recipient, the actual dollar change may be more or less than the average increase. Social Security will provide each recipient’s updated benefit amount.

The 2027 maximum amount of earnings subject to Social Security payroll taxes also rises, to $192,300. That figure applies to workers subject to Social Security payroll taxes; it does not change the COLA calculation for people already receiving benefits.

The CPI-W is a broad inflation measure, and some advocates argue that it may not fully reflect older adults’ spending patterns, particularly healthcare costs. They support considering the CPI-E, an experimental index focused on older consumers. The current COLA calculation, however, uses CPI-W.

As Shannon Benton, executive director of the Senior Citizens League, put it: “While a 3.6% COLA is certainly welcome, it wouldn't necessarily restore the purchasing power seniors have already lost. The COLAs are designed to keep pace with inflation, not make up for years of falling behind.” Government data cited by the League show the senior poverty rate rose to 15.4% last year, from 14.2% in 2022. The increase is welcome, but it may not resolve every household’s budget pressure.

Where the raise meets Medicare

Premiums may reduce the net increase

Many people have their Medicare Part B premium deducted directly from their Social Security payment. Some also have their Part D premium, Part D income-related surcharge, or Medicare Advantage plan premium withheld from benefits. Others pay those costs separately.

That means the amount deposited in your bank account may not rise by the full amount of your gross COLA. The final Medicare Part B premium for 2027 is a key part of the calculation, and you should check your official notices for your personal updated benefit and premium amounts rather than assuming the entire average $75 will be available to spend.

A higher benefit does not automatically trigger IRMAA

IRMAA is Medicare’s income-related surcharge for Part B and Part D. Social Security generally determines it using modified adjusted gross income (MAGI) from two years earlier. That means the 2027 IRMAA determination generally looks at 2025 income, not the 2027 Social Security benefit.

Still, the taxable portion of Social Security benefits can be part of the broader income picture. A higher benefit could contribute to taxable income and affect a future IRMAA determination, depending on your overall finances. The COLA alone does not automatically put you into a higher IRMAA bracket.

Review your Part D coverage, too

For 2027, the Part D out-of-pocket cap for covered prescription drugs is $2,400. Once you reach the applicable limit, your cost-sharing for covered Part D drugs is generally $0 for the rest of the year, subject to the program’s rules. This is a limit on Part D drug spending, not a cap on all medical costs.

The temporary Part D Premium Stabilization Demonstration for stand-alone drug plans ends after 2026. That does not mean every plan’s premium will rise by the same amount, or that every enrollee should switch. It does mean that reviewing your own plan’s premium, covered medications, pharmacy network and cost-sharing is important. For details, see our guide to the 2027 Medicare Part D review and our explanation of the 2027 $2,400 Part D drug cap.

Use AEP to see what your raise will actually cover

Medicare’s Annual Enrollment Period (AEP) runs October 15 through December 7. Changes made during this period generally take effect January 1, 2027. If you’re searching for “Medicare Advantage open enrollment 2027,” this fall period is commonly called Medicare Open Enrollment or AEP; the separate Medicare Advantage Open Enrollment Period takes place later in the year.

Before choosing to stay with or change your coverage, compare your 2027 plan documents with your needs:

• Review your Annual Notice of Change for premiums, deductibles, copays and benefits.
• Confirm your doctors, hospitals and preferred pharmacy are in network, if applicable.
• Check that your medications are covered and compare their cost under the plan.
• Consider the total cost of coverage, not just the monthly premium.
• Compare your updated Social Security benefit with expected Medicare costs before counting the full increase in your budget.

Minnesota’s Medicare Supplement options differ from the federal lettered-plan structure: residents generally see Basic or Extended Basic coverage, with optional riders. Minnesota also has an annual Medicare Supplement guaranteed-issue window from October 15 through December 7, as well as a one-time guaranteed-issue opportunity for eligible residents ages 65 to 70, regardless of pre-existing conditions. Medigap rights and eligibility are distinct from Medicare Advantage and Part D enrollment rules, so confirm how state rules apply to your situation.

Frequently asked questions

How much is the 2027 Social Security COLA?

The 2027 COLA is 3.6%. It adds roughly $75 per month to the average benefit, bringing it to about $2,170. Your own increase depends on your benefit amount.

Will Medicare premiums take my COLA increase?

Medicare premiums may reduce the amount of your COLA that reaches your budget. Part B premiums are often deducted from Social Security benefits, and some people arrange to have other Medicare premiums withheld as well. Check your updated notices to understand your net amount.

Does a bigger Social Security check affect IRMAA?

Not automatically. IRMAA generally uses MAGI from two years earlier, so a 2027 determination generally looks at 2025 income. The taxable portion of benefits may contribute to the overall income calculation in a later year.
