2027 Medicare Part B Premium: How Much Could It Be?
The 2027 Medicare Part B premium has not been officially finalized yet. The 2026 Medicare Trustees Report estimates the standard 2027 Part B premium at $209.50 per month. That would be $6.60 more than the official 2026 standard premium of $202.90. However, $209.50 is a projection — not the final 2027 premium. CMS will determine the actual 2027 premium later in 2026.
What Is the Projected 2027 Medicare Part B Premium?
The latest official Medicare Trustees projection puts the 2027 standard monthly Medicare Part B premium at $209.50.
The standard Part B premium in 2026 is $202.90 per month.
If the Trustees’ estimate becomes the final amount, that would mean:
- Monthly increase: $6.60
- 2026 premium: $202.90
- Projected 2027 premium: $209.50
- Additional annual cost: $79.20
2026 vs. Projected 2027 Medicare Part B Premium
| Year | Standard Monthly Premium | Status |
|---|---|---|
| 2025 | $185.00 | Official |
| 2026 | $202.90 | Official |
| 2027 | $209.50 | Trustees projection |
If the projection holds, the increase from 2026 to 2027 would be much smaller than the increase beneficiaries experienced between 2025 and 2026.
Is $209.50 the Official 2027 Medicare Premium?
No.
This is the most important distinction for anyone reading Medicare premium headlines before CMS releases its final figures.
The Medicare Trustees estimate future Medicare costs and financing. Their 2026 report estimates a monthly Part B premium of $209.50 for 2027.
But actual Part B financing rates have only been established through December 31, 2026.
If you see an article saying “The 2027 Medicare premium is $209.50,” check whether it clearly identifies that amount as the current Trustees projection.
When Will the Official 2027 Part B Premium Be Announced?
CMS normally announces the following year’s Medicare Part A and Part B premiums, deductibles and related cost-sharing amounts later in the year.
For comparison, CMS released its official 2026 Part A and Part B premium information on November 14, 2025.
That does not guarantee the same calendar date for the 2027 announcement.
Wait for CMS to publish the official 2027 Medicare Parts A & B Premiums and Deductibles announcement before treating any 2027 Part B amount as final.
How Much More Would $209.50 Cost Per Year?
If the projected $209.50 standard premium becomes final, a beneficiary paying the standard rate would pay:
| 2026 | Projected 2027 | |
|---|---|---|
| Monthly | $202.90 | $209.50 |
| Annual | $2,434.80 | $2,514.00 |
| Difference | — | +$79.20/year |
These calculations simply multiply the standard monthly premium by 12. They do not account for IRMAA, Medicaid assistance or other individual circumstances.
What Is the Medicare Part B Deductible in 2026?
The official Medicare Part B annual deductible for 2026 is $283.
That increased from $257 in 2025.
Why Does the Medicare Part B Premium Change?
Part B helps cover services such as physician services, outpatient hospital services, certain home health services, durable medical equipment and other covered medical services.
Premiums are determined annually under provisions of the Social Security Act and reflect projected Part B program costs and financing.
For 2026, CMS said the premium and deductible increase was mainly related to projected price changes and expected utilization increases.
Will Everyone Pay $209.50 in 2027?
No.
Even if $209.50 ultimately becomes the standard 2027 premium, not every Medicare beneficiary would necessarily pay that amount.
Higher-income beneficiaries may pay an additional Income-Related Monthly Adjustment Amount (IRMAA).
Some lower-income beneficiaries may qualify for Medicaid or a Medicare Savings Program that helps pay Medicare premiums and other costs.
Other special rules can also affect what an individual actually pays.
What Are the 2026 Medicare IRMAA Limits?
For 2026, CMS applies higher Part B premiums when modified adjusted gross income exceeds specified thresholds.
| 2026 Tax-Filing Category | Income | 2026 Part B Premium |
|---|---|---|
| Individual | $109,000 or less | $202.90 |
| Joint | $218,000 or less | $202.90 |
| Individual | Over $109,000 to $137,000 | $284.10 |
| Joint | Over $218,000 to $274,000 | $284.10 |
| Individual | Over $137,000 to $171,000 | $405.80 |
| Joint | Over $274,000 to $342,000 | $405.80 |
Those are 2026 figures. Do not use them as the 2027 IRMAA brackets. The 2027 income thresholds and premium amounts need to be updated when CMS publishes them.
Will the 2027 Medicare Premium Be Deducted From Social Security?
For many beneficiaries, Medicare Part B premiums are deducted directly from Social Security benefits.
That means the Part B premium matters when calculating how much of a Social Security COLA ultimately appears in a beneficiary’s bank deposit.
How Could the 2027 Medicare Premium Affect the Social Security COLA?
The 2027 Social Security COLA has not yet been finalized.
Therefore, it is too early to state exactly how much a typical beneficiary’s net Social Security payment will change in 2027.
However, once both figures are official, a simplified calculation will look like this:
+ 2027 COLA increase
− applicable 2027 Medicare Part B premium
− any other applicable deductions
= approximate net monthly payment
Example: What If the Part B Premium Is $209.50?
Suppose a beneficiary’s gross Social Security benefit increases by $70 per month because of the eventual 2027 COLA.
If that person’s standard Part B premium rises from $202.90 to $209.50, the Medicare increase would be $6.60.
| Example | Change |
|---|---|
| Gross Social Security increase | +$70.00 |
| Possible Part B premium increase | −$6.60 |
| Approximate remaining increase | +$63.40 |
This is only an illustration. It is not a prediction of anyone’s actual 2027 Social Security deposit.
What Is the Medicare Hold-Harmless Provision?
There is also an important rule known as the Part B hold-harmless provision.
The Medicare Trustees explain that, for most beneficiaries to whom the rule applies, it limits the dollar increase in the Part B premium to the dollar increase in the person’s Social Security benefit.
Not every Medicare beneficiary is protected by the provision, so individual circumstances matter.
Does Medicare Advantage Use the Same $209.50 Premium?
Medicare Advantage and Medicare Part B premiums should not be confused.
A Medicare Advantage plan can have its own plan premium, depending on the plan.
Beneficiaries generally must continue to meet their Part B premium obligation while enrolled in Medicare Advantage unless a particular arrangement or assistance program affects what they pay.
CMS has separately released information about projected Medicare Advantage and Part D plan premiums for 2027. Those figures are not the same thing as the standard Medicare Part B premium.

What Should Medicare Beneficiaries Do Now?
There is no special action required simply because the Trustees projected a $209.50 premium.
Instead, beneficiaries should wait for CMS to publish the official 2027 Part B premium and deductible.
Social Security recipients should also wait for the official 2027 COLA before trying to calculate their final January 2027 net payment.
1. Official 2027 Social Security COLA
2. Official 2027 Medicare Part B premium
Once both are known, beneficiaries will have a much clearer picture of how their 2027 monthly payments could change.
Bottom Line
The latest Medicare Trustees projection estimates the 2027 standard Medicare Part B premium at $209.50 per month.
That would be an increase of $6.60 per month from the official 2026 premium of $202.90, or about $79.20 more over a full year.
But the key word is projected.
The $209.50 figure is not yet the final CMS premium for 2027. BillUnpacked will update this page when CMS publishes the official 2027 Part B premium, deductible and IRMAA information.
