Average Social Security Benefit Could Rise by $900 in 2027, But There’s a Catch

Millions of Americans who receive Social Security are on track for a benefit increase in 2027. The Social Security Administration announced a 3.6% cost-of-living adjustment, the biggest boost since 2023, which is scheduled to begin with January 2027 payments. That would lift the average retired worker’s monthly benefit from $2,095 to about $2,170.

That amounts to roughly $75 more each month, or about $900 over a full year, before any deductions. For retirees trying to make their money last, the increase could provide some relief from rising costs.

Here’s what the 2027 COLA means, including the impact of higher Medicare premiums.

Who qualifies for the increase and when it begins

The higher payments will apply to nearly 72 million Social Security beneficiaries, with the increase showing up in January payments. About 7.3 million people who receive Supplemental Security Income, or SSI, would get their money a bit earlier, on Dec. 31, 2026. Some recipients collect both benefits.

Married retirees who both receive benefits would see a larger dollar gain. The SSA says the average monthly benefit for such couples would climb from $3,238 to $3,355, or about $117 more per month and just over $1,400 more over a year.

Disabled workers and surviving spouses would receive smaller dollar increases because their current benefits are lower. The average payment for a disabled worker would rise from $1,642 to $1,701 a month. For an aged widow or widower receiving benefits alone, the average would increase from $1,936 to $2,005. For SSI, the maximum federal payment for an individual would go from $994 to $1,029 a month.

How the SSA arrived at the 3.6% boost

The Social Security Act uses a formula linked to the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W, an inflation gauge published monthly by the Bureau of Labor Statistics.

To set the 2027 increase, the SSA compared the average CPI-W for the third quarter of 2026 with the same period in 2025. That average rose 3.6%, so benefits increase by the same amount. The 2027 COLA is higher than the 2.8% increase in 2026 and marks the sixth straight year of a COLA of at least 2.5%.

How Medicare premiums can shrink the raise

For people enrolled in Medicare, part of the increase is likely to be offset by higher premiums. Most Medicare beneficiaries have their Part B premium automatically withheld from their Social Security check, so a premium hike reduces the size of the net increase.

The Part B premium is determined separately from the COLA. The standard premium is $202.90 a month in 2026, up $17.90 from $185 in 2025. Those figures were announced by CMS in late 2025, and the 2027 premium has not yet been released.

Medicare trustees projected in June that the standard premium could rise to $209.50 in 2027, an increase of $6.60. If that estimate holds, the average retired worker’s monthly deposit would rise by about $68 instead of $75. Higher-income beneficiaries pay more. Roughly 8% of Part B enrollees pay income-related surcharges, which can push the premium as high as $689.90 a month.

Why larger benefits bring larger dollar increases

The SSA applies the same percentage increase to each benefit, so a $1,500 monthly payment would rise by about $54, while a $3,000 monthly payment would rise by about $108. Since benefits are tied to lifetime earnings, people with higher earnings histories generally see bigger dollar gains.

The same pattern shows up when premiums rise. If the Part B premium increases by the projected $6.60, that would eat up about 12% of the $54 raise but only about 6% of the $108 raise.

Why some critics say the increase still falls short

The Senior Citizens League, a senior advocacy organization, says COLAs based on CPI-W do not reflect the expenses older Americans actually face.

In its 2026 Loss of Buying Power study, the group priced 70 goods and services the way a senior relying only on Social Security might shop. It found those costs rose about 43.6% from 2016 to 2026, compared with a 37.6% increase in CPI-W.

TSCL estimates that Social Security benefits have lost 13.7% of their purchasing power since 2016. Restoring that lost ground would require a 15.7% benefit increase, or about $296 a month for the average recipient. Switching to a different index for COLA calculations would require Congress to change the law.

How to check your exact 2027 payment

The SSA will send each beneficiary a one-page notice showing the new benefit amount, payment schedule, and any deductions. People with a my Social Security account will be able to view the notice online starting in late November, up to three weeks before paper notices are mailed. Medicare beneficiaries will also see their 2027 premium amount in the account’s Message Center.

Account holders can choose to receive a text or email alert when the notice is posted. Those who have not signed up for paperless notices may receive the COLA notice by mail in December.

The bottom line

The 3.6% COLA would add about $75 a month to the average retired worker’s 2027 benefit. If the Medicare trustees’ premium projection comes to pass, a Medicare enrollee with an average benefit would keep about $68 of that increase.

Income taxes could also take a share of the raise. If your income plus half your benefits exceeds $25,000 as a single filer or $32,000 for joint filers, part of your benefits becomes taxable, and those thresholds are not indexed for inflation. That means each COLA can push more retirees closer to them. Planning around those limits may help you keep more money in hand.
