Social Security Checks Are Getting a $75 Raise in 2027 and Medicare’s Premium Hike Is Much Smaller This Year

Social Security’s cost-of-living adjustment (COLA) announcement is the most important day of the year for many retirees. For those who get most or all of their retirement income from Social Security, any raise that arrives is crucial.
The Social Security Administration made the 2027 COLA official on October 14, 2026, and the number came in on the higher end of what analysts had forecast.
The official 2027 COLA is 3.6%
The Social Security cost-of-living adjustment will be 3.6% in 2027, the Social Security Administration announced. The 3.6% COLA for 2027 is the largest increase to benefits since 2023. For context, the COLA was 2.8% in 2026, 2.5% in 2025, and 3.2% in 2024.
The 3.6% adjustment will boost the average monthly benefit for a retired worker by about $75 in January, from $2,095 to $2,170, according to SSA estimates. That works out to roughly $900 more per year for the typical retired worker.
“Social Security will implement this cost-of-living adjustment for 76 million Americans, giving them greater financial stability,” Social Security Commissioner Frank Bisignano said in a statement.
The final figure matched the Senior Citizens League’s late-summer estimate and came in above earlier projections from earlier in 2026, driven by higher energy costs in the third quarter. The SSA bases the COLA on the CPI-W, which averaged 328.746 in the third quarter of 2026, up 3.6% from 317.265 a year earlier.
Medicare Part B hikes could still trim next year’s raise
Even with a solid COLA in hand, retirees enrolled in both Social Security and Medicare need to watch one other number: the Medicare Part B premium. Seniors who receive Social Security have Part B costs deducted directly from their monthly checks, so any premium increase reduces the net gain they take home.
The good news here is that the projected 2027 Part B hike is far milder than the jump retirees absorbed last year. The standard premium rose 9.7%, or $17.90, to $202.90 for 2026. The latest Social Security and Medicare Trustees Report estimates that Part B premiums will climb 3.5% in 2027, reaching $209.50 per month, up $6.60 from 2026.
Official 2027 rates, including IRMAA bracket amounts, will be announced in November. Some private analysts expect the actual figure to land a few dollars higher than the trustees’ projection, but even a premium in the $215 to $219 range would represent a much smaller bite than 2026’s nearly $18 increase.
If the $6.60 projected increase holds, the average retiree would net roughly $68 of their $75 COLA gain after the Part B deduction. That is a considerably better outcome than the arithmetic looked like earlier in the year, when analysts were still using the previous trustees’ projection of $218.60 for 2027 Part B.
What these numbers mean for retirees going forward
The combination of a 3.6% COLA and a modest Part B increase is the best outcome retirees could have hoped for heading into 2027. A $68 net monthly gain is a tangible lift. For a retired couple with both spouses receiving benefits, the household pickup is closer to $130 per month before any premium adjustments.
That said, a recent AARP survey found 76% of respondents said a 3.5% COLA would not be enough. Many seniors point out that their actual spending, particularly on healthcare and housing, has risen faster than the CPI-W measures used to calculate the COLA. The adjustment is designed to track inflation broadly, not to compensate for the specific cost pressures retirees face.
Retirees should watch for two remaining announcements before the end of 2026. CMS will set the official 2027 Part B premium in November, and beneficiaries will receive personalized notices detailing their new benefit amounts in December. Those notices will reflect the net change after any premium adjustment, giving retirees the clearest picture of what their January check will actually look like.
Editor’s note: This article has been updated to reflect the Social Security Administration’s official announcement of a 3.6% COLA for 2027, made on October 14, 2026, lifting the average retired worker’s monthly benefit by $75 to $2,170. The projected 2027 Medicare Part B premium increase was also updated to $6.60 (to $209.50), a far smaller premium bite than the ~$18 increase absorbed in 2026, based on the 2026 Medicare Trustees Report.
