The official 2027 Medicare Part B premium has not been announced yet. The 2026 Medicare Trustees Report estimates the standard premium at $209.50 a month, up $6.60 from $202.90 in 2026, with a $292 annual deductible, up $9 from $283. CMS usually publishes the final amounts in the fall; last year it did so on November 14. Until then, treat $209.50 as an estimate, not a bill.
Key takeaways
- The Trustees' estimate for the 2027 standard Part B premium is $209.50 a month, up 3.25% from $202.90. The final amount comes from CMS.
- The estimated 2027 Part B deductible is $292, up $9 from $283 in 2026. Like the premium, it is an estimate until CMS confirms it.
- On a $1,800 benefit, the 3.6% COLA adds $64.80 a month. If Part B rises $6.60, you keep about $58.20 of that raise.
- Higher earners pay more. In 2026, the surcharge starts above $109,000 for one person and $218,000 for a couple. The 2027 cutoffs are not out yet.
- Most people pay Part B out of their Social Security check, so the new premium shows up as a smaller net deposit, not a separate bill.
If you have Medicare, one of the next big money numbers is the 2027 Part B premium. Part B is the part of Medicare that covers doctor visits and outpatient care. The official 2027 amount is not out yet, but government actuaries have already given an estimate.
This matters because most people pay the premium straight out of their Social Security check. A bigger premium means a smaller raise. Here is what is known, what is not, and how to plan.
What is the 2027 Medicare Part B premium?
Nobody can give you the final number today. What exists is an estimate from the 2026 Medicare Trustees Report, the yearly financial checkup of the program. The Trustees estimate a standard Part B premium of $209.50 a month for 2027. They also say that is an estimate: actual amounts are “likely to be somewhat different as experience emerges.”
CMS, the agency that runs Medicare, sets the real premium. For 2026 it published the numbers on November 14, 2025, according to its fact sheet. CMS has not announced a date for the 2027 release.
How much could the premium and deductible change?
Here is the Trustees’ estimate next to the official 2026 amounts:
| 2026 (official) | 2027 (Trustees’ estimate) | Change | |
|---|---|---|---|
| Standard monthly premium | $202.90 | $209.50 | +$6.60 |
| Annual premium (12 × monthly) | $2,434.80 | $2,514.00 | +$79.20 |
| Annual deductible | $283 | $292 | +$9 |
The $6.60 jump is about 3.25% ($6.60 ÷ $202.90). That is smaller than the $17.90 increase from 2025 to 2026, when the premium went from $185.00 to $202.90.
The deductible is what you pay once a year before Original Medicare starts to pay its share. Afterward you usually pay 20% of the cost of covered services, per Medicare.gov.
Will the Part B increase eat my Social Security raise?
It will take a bite, but a small one at today’s estimate. Social Security announced a 3.6% cost-of-living adjustment (COLA) for 2027. A COLA is the yearly raise meant to keep benefits in step with prices.
Here is an illustration with made-up round numbers, not your own benefit:
- COLA on a $1,800 monthly benefit: $1,800 × 0.036 = $64.80
- Estimated Part B increase: $209.50 − $202.90 = $6.60
- Raise you keep: $64.80 − $6.60 = $58.20 a month, or about 3.2% of $1,800
If the final premium comes in higher or lower than the estimate, your number moves with it. For a full look at the raise, see our 2027 COLA explainer.
Why do some people pay more than the standard premium?
Higher-income enrollees pay an extra charge called IRMAA (income-related monthly adjustment amount). It is based on your tax return from two years earlier. CMS says roughly 8% of people with Part B pay it. These are the 2026 amounts for full Part B coverage:
| Income, single | Income, married filing jointly | Total monthly premium, 2026 |
|---|---|---|
| $109,000 or less | $218,000 or less | $202.90 |
| $109,000 to $137,000 | $218,000 to $274,000 | $284.10 |
| $137,000 to $171,000 | $274,000 to $342,000 | $405.80 |
| $171,000 to $205,000 | $342,000 to $410,000 | $527.50 |
| $205,000 to under $500,000 | $410,000 to under $750,000 | $649.20 |
| $500,000 or more | $750,000 or more | $689.90 |
The 2027 income cutoffs have not been published, so do not assume these tiers stay the same.
Can the premium rise more than my benefit?
For many people, no. The Trustees Report describes a hold-harmless rule for people whose premium is taken out of their Social Security check. It says the premium’s dollar increase cannot be larger than the dollar increase in the Social Security benefit. The Trustees say it covers roughly 70% of enrollees.
With a 3.6% COLA, your benefit would have to be tiny for this to matter. A $6.60 premium rise is more than a 3.6% raise only on benefits below about $183 a month ($6.60 ÷ 0.036). The rule does not apply to everyone, so check your own situation with Social Security or Medicare.
What to do now
- Write down your current premium. Look at your Social Security statement or your Medicare bill. In 2026 the standard amount is $202.90 a month.
- Budget with a cushion. Use $209.50 as a planning number, but expect it to change. Our retirement calculator can show how a few extra dollars a month add up.
- Watch for the official release. Check the CMS newsroom and Medicare.gov in mid-November. Then compare the real premium with your 3.6% COLA.
- Look at your plan options. Medicare open enrollment runs through December 7. Our open enrollment guide covers what to compare.
- See what prices are doing. The inflation calculator shows how a 3.6% raise compares with price changes over time.

Frequently asked questions
What will the Medicare Part B premium be in 2027?
No one knows the official number yet. The 2026 Medicare Trustees Report, published June 9, 2026, estimates $209.50 a month for the standard premium. CMS sets the real amount and usually announces it in the fall. Last year's announcement came on November 14, 2025. Until CMS publishes 2027 figures, any exact number you see is a projection.
When will CMS announce the 2027 Part B premium?
CMS has not said a date. For 2026, it announced the premium and deductible on November 14, 2025, so a mid-November release is possible again, but that is a pattern, not a promise. Watch the CMS newsroom and Medicare.gov. This article will not show an official number until CMS publishes one.
How much is the Part B premium in 2026?
The standard Part B premium in 2026 is $202.90 a month, up $17.90 from $185.00 in 2025. The annual deductible is $283, up from $257. After you meet the deductible, Original Medicare usually pays 80% of covered outpatient costs and you pay 20%. Higher-income enrollees pay more, as the table in this article shows.
Will the Part B increase eat my Social Security COLA?
Not all of it. The 2027 COLA is 3.6%. If the premium rises by the estimated $6.60, someone with a $1,800 benefit gains $64.80 and loses $6.60, for a net raise of about $58.20 a month. The Part B increase takes a bigger share of the raise for people with smaller benefits.
Do I pay a higher Part B premium if my income is high?
Yes. This is called IRMAA, the income-related monthly adjustment amount. In 2026 it applies if your income from two years earlier is above $109,000 (single) or $218,000 (married filing jointly). CMS says about 8% of people with Part B pay it. The 2027 income cutoffs have not been announced.
Can the Part B premium go up more than my Social Security raise?
For most people who have the premium taken from their benefit, a hold-harmless rule says the premium's dollar increase cannot be larger than the dollar increase in the Social Security benefit. The Trustees say it covers roughly 70% of enrollees. With a 3.6% COLA, it only matters for very small benefits.
