Social Security sets 3.6% COLA for 2027, the biggest raise since 2023
Retirees will get about $75 more a month on average next year, but rising Medicare premiums and faster inflation mean the boost may feel smaller than it looks.
The short answer
The Social Security Administration said benefits will rise 3.6% in 2027, the largest cost-of-living adjustment since 2023. Average retirement checks go up about $75 a month. About 72 million Social Security recipients get the raise in January, while 7.3 million SSI recipients see it from December 31.
What happened
On Wednesday the Social Security Administration announced a 3.6% cost-of-living adjustment, or COLA, for 2027, up from 2.8% this year. The agency said the average retirement benefit will climb by $75 a month. Roughly 72 million Social Security beneficiaries will see higher payments from January, and about 7.3 million people on Supplemental Security Income, a separate program for those with very low incomes, will be paid more starting December 31. Commissioner Frank Bisignano said the change would cover 76 million Americans. The figure matched experts' forecasts of 3.5% to 3.6%.
What it means
The COLA is not set by politicians each year. It follows a formula tied to one inflation gauge, the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W. The agency compares the average of that index in July, August and September with the same three months a year earlier. September data released the same morning showed CPI-W up 3.9% over 12 months, slightly faster than the 3.7% rise in the broader consumer price index.
This is the biggest increase since 2023, when benefits rose 8.7% after the post-pandemic price surge. The jump from 2.8% reflects how higher fuel costs since the Iran war began in late February have pushed inflation back up. Gasoline prices rose 9.1% in September alone, according to the Bureau of Labor Statistics.
For many households the raise matters a great deal. About 40% of beneficiaries aged 65 and over rely on Social Security for at least half their income, according to AARP. Yet an AARP survey found 76% of respondents felt a 3.5% increase would fall short. One reason is that the COLA looks backward: it reflects price rises that have already happened, so if inflation keeps climbing, retirees may feel squeezed before the next adjustment arrives.
Medicare costs will also eat into the gain. Medicare trustees project the standard Part B premium at $209.50 a month in 2027, up from $202.90, and that charge is often taken straight out of benefit checks. Prescription drug plans under Part D may also cost a little more, according to health research group KFF. How the COLA is measured is itself a live debate, with some proposals favoring alternative indexes that could change raises over time.
The bull case
A 3.6% raise puts about $75 more into the average retiree's monthly check, which supports spending on essentials and gives older households a cushion at a time when prices are climbing. Because the adjustment is automatic and tied to inflation, Social Security remains one of the few income sources that keeps pace with the cost of living without any action from recipients.
The bear case
The increase reflects past inflation, not future price rises. With energy costs still climbing and Medicare Part B premiums set to rise by $6.60 a month, the real gain for many retirees will be smaller. Bigger COLAs also raise the program's costs, which adds to long-running worries about Social Security's finances and could feed calls for reform that change how future raises are calculated.
Why it matters
For investors
Higher benefit payments modestly support consumer spending among older Americans, which can help sellers of everyday goods and health care services. The bigger market signal is the inflation data behind the raise, which pushed Treasury yields higher.
The wider context
Retirees can estimate their own raise by multiplying their current monthly benefit by 0.036, then subtracting any premium increase. For people still working, the episode is a reminder that inflation protection matters when planning retirement income.
Market impact
| Asset (ticker) | Possible move | Timeframe | Why |
|---|---|---|---|
| US 10-year Treasury yield | ↑ Up | Short term | The same hot inflation data behind the COLA lifted rate-hike bets and yields. |
| Consumer Staples Select Sector SPDR Fund (XLP) | ↔ Unclear | Long term | Larger checks support essential spending, but rising costs absorb much of the gain. |
