2027 Medicare Part B Premium: The Smallest Increase in Years, and What Florida Families Should Know
For the first time in a couple of years, a Medicare cost projection actually reads as good news. The 2026 Medicare Trustees Report puts the 2027 standard Part B premium at roughly $209.50 a month, a $6.60 increase over 2026's confirmed $202.90, or about 3.25%. That would be the smallest percentage jump since 2023, and a sharp break from the nearly 10% increase that hit beneficiaries between 2025 and 2026. For Florida families managing a parent's or spouse's fixed budget, that is real relief, with one important caveat: this number isn't final, and the analysts who track these projections for a living think it's probably too low.
The number CMS hasn't confirmed yet
CMS won't announce the official 2027 Part B premium until its annual fall notice, typically released in November. Everything below that point is a projection, not policy. Here's how the number has moved over the past three years:
| Year | Standard Part B premium | Year-over-year change |
|---|---|---|
| 2025 | $185.00 (confirmed) | +5.9% |
| 2026 | $202.90 (confirmed) | +9.7% |
| 2027 | ~$209.50 (Trustees' projection) | ~+3.25% |
The 2026 jump was one of the steepest in the program's recent history, so a projected 3.25% increase for 2027 is a genuine change of direction, assuming it holds.
Why the real number could land closer to $218
That "assuming it holds" is doing a lot of work. Independent forecasters, including several who publish annually on Medicare trends, are projecting a 2027 premium in the $216 to $219 range, well above the Trustees' $209.50 baseline. Their reasoning is grounded in recent track record: the Trustees have underestimated the actual premium increase in each of the last two years.
The projections themselves have also been unstable. The 2025 Trustees Report projected a 2027 premium of $218.60. A year later, the 2026 report dropped that same 2027 estimate to $209.50, a swing of more than $9 in a single revision cycle. That kind of volatility is exactly why families shouldn't treat any early projection as a number to bank on. If the final premium lands closer to $218 instead of $209.50, the difference works out to roughly $100 a year, money that matters on a fixed income.
What else changes in 2027
The premium isn't the only cost moving. A few other pieces worth tracking as CMS finalizes 2027 numbers:
- Part B deductible. The 2026 deductible rose to $283, up from $257 in 2025. The Trustees Report projects a comparable increase for 2027, confirmed alongside the premium in November.
- IRMAA surcharges. Higher-income beneficiaries pay more than the standard premium through Income-Related Monthly Adjustment Amounts, determined using tax returns from two years prior (2025 returns for 2027 IRMAA). Projected 2027 brackets are already circulating, and it's worth checking now whether a parent's income is near a threshold.
- Part D out-of-pocket cap. The $2,000 annual cap on prescription drug costs, one of the more significant recent changes to Medicare, continues into 2027. Part D premiums move on a separate track from Part B and aren't part of this projection.
The number that actually decides the household budget
The Part B premium increase matters less in isolation than it does next to the Social Security cost-of-living adjustment, since Part B premiums are typically deducted straight from a Social Security check. Early 2027 COLA estimates range from about 3.6% to 3.8%, which on an average benefit of roughly $1,937.53 works out to something like a $70 to $74 monthly increase.
If that COLA estimate holds and the Part B premium comes in anywhere near the Trustees' $209.50 projection, most beneficiaries should see their check grow faster than their premium, a rare combination for a program that's spent the last two years going the other direction. But if the premium lands at the higher end of private forecasts, closer to $218, a meaningful share of that COLA gets absorbed before it ever reaches the bank account. The official COLA number arrives in October, about a month before the confirmed Part B premium, so families will have a short window to see one number before the other.
What Florida families should do before November
A few concrete steps make more sense than waiting for the official announcement:
- Budget for the higher estimate. Plan around $216 to $219 rather than $209.50. If the confirmed number comes in lower, that's a pleasant surprise instead of a shortfall.
- Check IRMAA exposure now. If a parent's 2025 income is close to a bracket threshold, even a small amount of extra income (a Roth conversion, a capital gain, a required minimum distribution) can push next year's premium sharply higher. This is worth reviewing with a tax preparer before year-end, not after.
- Watch the October COLA announcement, then the November premium notice. Seeing both numbers together is the only way to know whether a household is actually ahead or behind for 2027.
- Use open enrollment (October 15 to December 7) for the full picture. The Part B premium is only one line item. Enrollment season is also the window to compare Part D drug plans and Medigap coverage against what a parent actually needs for the year ahead.
For families further along in the caregiving journey, Medicare and Social Security numbers are only part of the budget. If a parent is also weighing assisted living or memory care costs in Florida, or comparing facilities across the state through our Florida directory, these premium and COLA figures are the starting point for what's actually left in the monthly budget for care. Veterans and surviving spouses should also check whether VA Aid and Attendance offsets some of that gap, and anyone managing a GLP-1 prescription alongside Medicare should see our breakdown of what Medicare will and won't cover.
The bottom line
The 2027 Medicare Part B premium is trending toward the smallest percentage increase in years, and for a program that just delivered a nearly 10% jump, that's a real change in direction. But "smallest increase in years" and "$209.50" are both still projections, not confirmed numbers, and the analysts with the best track record think the real figure lands higher. Plan for $216 to $219, watch the COLA announcement in October, and treat CMS's November confirmation as the number that actually matters. We'll update this post with the official 2027 premium as soon as CMS releases it.

Frequently Asked Questions
What is the projected Medicare Part B premium for 2027?
The 2026 Medicare Trustees Report projects a standard Part B premium of approximately $209.50 a month for 2027, up from the confirmed $202.90 in 2026. That works out to roughly a 3.25% increase, the smallest percentage jump since 2023. CMS will not confirm the official number until its fall announcement, typically in November 2026.
Is the 2027 Medicare premium increase confirmed?
No. The $209.50 figure is a projection from the Medicare Trustees Report, not a confirmed CMS number. Independent forecasters expect the actual 2027 premium to land higher, in the $216 to $219 range, based on a pattern of the Trustees underestimating recent increases. The confirmed premium arrives in CMS's annual fall announcement.
How much will Medicare Part B premiums increase in 2027 compared to 2026?
If the Trustees' $209.50 projection holds, the increase from 2026's $202.90 would be about $6.60 a month, or 3.25%. That's a much smaller jump than the roughly 9.7% increase beneficiaries saw between 2025 and 2026, when the premium rose from $185.00 to $202.90.
Will the 2027 Social Security COLA cover the Medicare premium increase?
Early 2027 COLA estimates range from about 3.6% to 3.8%, which would raise the average Social Security check by roughly $70 to $74 a month. If the Part B premium increase lands near the Trustees' $209.50 projection, most beneficiaries should see their check grow faster than their premium. If the premium comes in closer to the higher $216 to $219 forecasts, a larger share of that COLA gets absorbed by Medicare before it reaches the bank account.
When will Florida seniors know the official 2027 Medicare Part B premium?
CMS typically confirms the coming year's Part B premium and deductible in a fall announcement released in November, ahead of Medicare's open enrollment period. The 2027 premium is expected to be confirmed around November 2026, roughly a month after the Social Security Administration announces the 2027 COLA in October.
How does IRMAA affect the 2027 Medicare Part B premium?
Beneficiaries with higher incomes pay more than the standard Part B premium through Income-Related Monthly Adjustment Amounts (IRMAA), based on tax returns from two years earlier. For 2027, IRMAA will be based on 2025 income. Projected 2027 IRMAA brackets are already available, and families should check now whether a parent's income is near a threshold before year-end tax decisions push it over.
