Social Security Sets 2027 COLA Announcement for October 14

About 70 million Americans receiving Social Security benefits will learn how much their monthly payments could increase in 2027 when the Social Security Administration announces its annual cost-of-living adjustment on October 14 at 8:30 a.m. ET. The projected 3.5% increase would be the largest since 2023, although higher Medicare expenses could reduce the additional money beneficiaries receive.

According to reporting by AL.com and 24/7 Wall St., The Senior Citizens League estimates a 3.5% adjustment, subject to September inflation data from the Bureau of Labor Statistics. The final calculation compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from July through September 2026 with the same period in 2025.

The projected adjustment exceeds the 2.8% increase for 2026 and the 2.5% increase for 2025. The Senior Citizens League's forecast has shifted throughout the year, falling from 3.9% in April to 3.6% in August and 3.5% in September, according to Nexstar Media Wire.

If the adjustment reaches 3.5%, the average monthly Social Security benefit would rise by $67.90, from $1,940.08 to $2,007.98, according to AL.com. The increase would apply to retirement, disability and survivor benefits, while the adjustment also affects Supplemental Security Income recipients under a separate payment schedule.

However, the amount beneficiaries ultimately retain will depend partly on Medicare costs. The Medicare Trustees Report projects that the standard Medicare Part B monthly premium will increase from $202.90 in 2026 to $209.50 in 2027, a rise of $6.60. Part B premiums are generally deducted directly from Social Security payments.

The projected annual Part B deductible would also climb from $283 to approximately $292. Meanwhile, standard deductions associated with Medicare Part D prescription drug coverage are projected to increase from $615 to $700, while the annual out-of-pocket limit would rise from $2,100 to $2,400, according to AL.com.

Medical expenses have already increased beneficiaries' costs. According to 24/7 Wall St., the standard Part B premium rose from $185 in 2025 to $202.90 in 2026, an increase of $17.90 per month, or approximately 9.7%. The 2026 Part B deductible reached $283, while the Medicare Part A hospital deductible rose to $1,736.

The same report cited the New York Fed's Survey of Consumer Expectations, which found that Americans anticipated medical care prices would increase 9.2% over the following year. That expectation exceeded the survey's 3.9% outlook for overall inflation, although the figures reflect respondents' expectations rather than official forecasts or retiree-specific projections.

Beyond annual inflation adjustments, the age at which a person claims retirement benefits can significantly affect monthly payments. A USA TODAY report from The Motley Fool illustrated the difference with a hypothetical worker whose primary insurance amount is $2,000 per month at a full retirement age of 67.

Claiming at 62 would reduce that hypothetical benefit by 30%, leaving $1,400 per month. Waiting until 70 would increase it by 24% to $2,480 per month, a difference of $1,080 compared with claiming at 62. The report noted that eligible beneficiaries who have already claimed may also have options to withdraw an application within 12 months, subject to repayment requirements, or suspend benefits after reaching full retirement age to earn delayed retirement credits.

The 2027 COLA will first affect January payments, although some beneficiaries will receive their money in December 2026 because of the payment calendar. Nexstar reported that Supplemental Security Income recipients scheduled to receive a payment on New Year's Day will instead be paid on December 31, 2026. The same schedule applies to people who began receiving Social Security before May 1997 and those who receive both Social Security and Supplemental Security Income.

The September inflation figures will determine the final COLA announced October 14. The Centers for Medicare & Medicaid Services is expected to release the 2027 Medicare Part B premium later in the year, with the announcement typically occurring in November.
