The Social Security Administration has officially announced a 3.6% cost-of-living adjustment for 2027, giving retirees a more generous raise than the 2.8% increase that many seniors criticized as insufficient this year.
For beneficiaries not enrolled in Medicare, calculating the 2027 raise is straightforward — simply multiply your monthly benefit by 3.6% to find your new payment amount.
However, millions of retirees who are enrolled in both Social Security and Medicare face a more complicated picture heading into the new year.
Medicare Part B premiums are automatically deducted from Social Security benefit checks, meaning any increase in those premiums will directly reduce the value of the COLA increase.
The average monthly Social Security benefit currently sits at $2,088, meaning the 3.6% COLA translates to roughly a $75 per month raise before accounting for any Medicare costs.
Last year, the Medicare Part B premium rose by $17.90 per month, which was considered a fairly significant increase, and a similar or larger hike is widely expected for 2027.
Even if Part B premiums rise by a comparable amount in 2027, the 3.6% COLA should be large enough that dual enrollees still see a meaningful net increase in their monthly benefits.
During years when the COLA is very small and Part B hikes are large, it is possible for seniors to end up with no effective Social Security raise at all, though that outcome is unlikely this cycle.
The standard monthly Part B premium currently stands at $202.90, though higher-income beneficiaries subject to surcharges known as IRMAAs may already be paying significantly more than that baseline figure.
The only way Medicare enrollees would keep their COLA entirely intact is if Part B premiums do not increase at all in 2027, which is not expected to happen based on current projections.
The Centers for Medicare and Medicaid Services typically reveals updated Part B premium costs in mid-November, meaning retirees may need to wait several more weeks before they can calculate their exact 2027 income boost.
Until that announcement is made, Social Security recipients who are also on Medicare should hold off on making detailed budget plans based solely on the 3.6% figure.
Financial planners generally advise retirees to treat the COLA announcement as a starting point rather than a final number, particularly for those with Medicare coverage factored into their monthly cash flow.
