Medicare Part B Premium Increase 2027: Trustees Project $209.50 a Month

The Medicare Part B premium increase for 2027 is projected at $6.60 a month, taking the standard premium to $209.50, according to the Medicare Trustees Report released by the CMS actuary in June 2026. That is up from $202.90 this year, a 3.25 percent rise, and it would be the smallest yearly increase since 2023. The trustees also expect the Part B deductible, which sits at $283 in 2026, to climb to $292 for 2027.

Why is the premium going up at all? The trustees report, the annual federal estimate of Medicare's finances, points to rising spending on physician services, outpatient hospital care and the drugs Part B covers. That cost is spread across roughly the more than 69 million people enrolled in Medicare, and the standard premium is set to cover about 25 percent of the program's expected outlays. The $6.60 figure is a projection, not a final decision; CMS sets the actual premium each fall, converting the trustees' estimate and updated cost data into the final number.

Put the 2027 move in context. This year's premium jumped by $17.90, or 9.7 percent, to reach $202.90. A rise of $6.60 is much gentler by comparison, yet it is still an increase in a year when the monthly benefit for the average retiree is going up by a Social Security cost-of-living adjustment that was initially set at 3.6 percent before a revision put it at 3.5 percent. A retiree whose Part B premium is withheld from the benefit check keeps a smaller slice of that raise than the headline COLA suggests, which is why the projected premium tends to draw so much attention from households on fixed incomes.

The bigger story sits further out. The trustees see the standard Part B premium climbing roughly 6 percent a year on average from 2026 through 2031, when it is projected to reach $272.10 a month. Over that same window the premium would rise about 34 percent from the current $202.90, and the annual hikes are expected to accelerate after the unusually small 2027 figure. For a retiree, that is a budget line that grows far faster than the typical 2 to 3 percent annual inflation. Lower-income seniors get some protection through the Medicare Savings Program, which pays Part B premiums for people who qualify, and higher earners pay more through the income-related monthly adjustment amount.

One more wrinkle is already in view for 2026. In early October, the administration announced a one-time payment of about $90 for roughly 20.8 million people to help with Part B premiums this month, according to reporting by AARP on a late-night Truth Social post. That payment covers less than half of a single month's standard premium and is not part of the 2027 projection, so it does not change the direction of next year's costs. The official 2027 premium and deductible will be announced by CMS this fall, and when the final number lands it will almost certainly track the trustees' $209.50 estimate closely, since past projections have been off by only a few dollars or cents.
