When retirees learned they’d be getting a 2.8% Social Security COLA in 2026, many weren’t happy and were quick to blast that raise as stingy and inadequate. While a 2.8% raise isn’t negligible, it paled in comparison to some of the COLAs that had come through in recent years.
But following that 2.8% COLA announcement, Social Security recipients got even worse news. And they may be headed for a repeat situation in 2027, depending on how two key numbers land this fall.
Will a large Medicare Part B hike erode the 2027 COLA?
A 2.8% COLA in 2026 didn’t have to be bad news. But Medicare made it sting. The standard Medicare Part B premium jumped from $185 a month to $202.90 in January 2026, a near-10% increase that wiped out roughly one-third of the average Social Security boost that a 2.8% COLA otherwise allowed for.
On the COLA front, 2027 projections are now looking more optimistic. The Senior Citizens League (TSCL) estimates next year’s raise at 3.6%, while AARP puts its projection at 3.5%. Either figure would mark a clear improvement over the 2.8% increase seniors received this year. For context, the average monthly retirement benefit stood at $2,086 as of July 2026, meaning a 3.6% COLA would add roughly $75 to the average check, bringing it to around $2,161 per month. The official announcement is scheduled for October 14, 2026, once all third-quarter inflation data are in.
The wildcard is once again Medicare. The 2026 Medicare Trustees Report projects the standard Part B premium will rise from $202.90 to about $209.50 in 2027, an increase of roughly $6.60 per month, or about 3.25%. That would be a far smaller hike than the nearly 10% jump seniors absorbed in 2026, which offers real relief. However, private forecasters caution that the Trustees have historically underestimated actual premium increases, and some analysts project the 2027 Part B premium could land between $216 and $219 when CMS finalizes the number in November 2026.
Even at the Trustees’ baseline of $209.50, the Part B increase would consume a portion of any COLA gain. At a higher premium closer to $215 or above, the net benefit to retirees shrinks further. The dynamic is familiar: even a generous-sounding COLA can quietly erode once Medicare takes its share.
It’s best not to be too reliant on Social Security COLAs
COLAs are determined by third-quarter inflation data, specifically changes in the Consumer Price Index for Urban Wage Earners (CPI-W). That index climbed from 2.2% in January 2026 to a peak of 4.4% in May before pulling back to 3.4% in July, which is part of why projections have shifted modestly from month to month. August and September readings will be decisive in setting the final number.
Meanwhile, Medicare is unlikely to reveal its official 2027 Part B premium until several weeks after the SSA’s October COLA announcement. That means seniors could face a frustrating wait before they can calculate their actual net benefit change for next year.
The broader takeaway from all of this is that depending heavily on Social Security COLAs to maintain purchasing power in retirement carries real risk. Many current retirees have learned that lesson the hard way. If you’re still working, treat this as a prompt to boost your retirement savings now. Carrying a diversified portfolio into retirement opens up access to investments that can outpace inflation over time, reducing the stress of tracking annual COLA and Part B announcements.
Current retirees aren’t without options either. Those on Medicare and collecting Social Security can still work part-time and direct extra income into assets that build value and generate regular income, such as dividend stocks.
The best scenario for 2027 is a COLA in the 3.5% to 3.6% range paired with a Part B increase that stays near the Trustees’ modest projection. If both break favorably at the same time, seniors could see a genuine net gain in purchasing power. But that outcome remains uncertain, and the Medicare Trustees’ own long-term outlook anticipates that premium growth will accelerate after 2027, making the years ahead more challenging, not less.
Editor’s note: This update adds the latest 2027 Social Security COLA projections from TSCL (3.6%) and AARP (3.5%), the current average monthly retirement benefit of $2,086 as of July 2026, the Medicare Trustees’ projected 2027 Part B premium of $209.50 (up from $202.90), and private-forecaster estimates of $216 to $219 for that premium, along with context on CPI-W trends through July 2026 and the confirmed October 14, 2026 COLA announcement date.
