Medicare Part B Premium 2027

The 2026 Medicare Trustees Report projects a standard 2027 Part B premium of $209.50 per month. That is a monthly increase of roughly $6.60 over the current $202.90, or about 3.25%.

One detail that tends to get lost: this projection was revised downward. The previous year’s Trustees Report had projected a 2027 premium of $218.60. Lower-than-expected Medicare spending through the first half of 2026 brought the estimate down. That is unusual, and it is a genuinely good sign for beneficiaries — but it is not a guarantee.

Some independent analysts think the final figure will land higher than the Trustees baseline, in the range of roughly $215 to $219 a month, pointing out that the Trustees have underestimated the final CMS number before. Both views are worth knowing, and neither is official.

Context helps here. The standard Part B premium has gone up in every year since 2020 except one, rising from $144.60 to $202.90 — a 40% increase over six years.

The 2023 decrease is the exception that explains a lot. The 2022 premium had been set unusually high partly to build a reserve for an expensive new Alzheimer’s drug. When that spending did not materialize, the 2023 premium came back down. It is a useful reminder that the Part B premium is driven by projected program spending, and projections can miss in both directions.

The large 2026 jump of $17.90 was attributed by CMS mainly to projected price changes and expected increases in how much care people use. CMS also noted that without action taken on spending in one specific category, the increase would have been roughly $11 a month higher.

The annual Part B deductible for 2026 is $283, up $26 from $257 in 2025. This is what you pay out of pocket for Part B services each year before Medicare starts paying its share.

CMS has not projected a 2027 deductible, and the Trustees Report does not publish one either. Historically the deductible moves in step with the percentage increase in the Part B premium. Applying the projected 3.25% premium increase to the current $283 would put the 2027 deductible at roughly $292. Some other published forecasts run higher, closer to $310.

◎Why you will see different deductible estimates

Different sources use different methods. Some apply the projected premium percentage, some use separate actuarial modeling. That is why published 2027 deductible estimates range from roughly $292 to roughly $310. We would rather show you the spread than pretend there is one settled answer.

If your income is above a certain level, you pay an Income-Related Monthly Adjustment Amount, or IRMAA, on top of the standard Part B premium. It affects roughly 8% of people with Part B.

Two things matter for 2027. First, IRMAA uses a two-year lookback, so your 2027 bracket will be determined by the income reported on your 2025 tax return. Second, the 2027 income thresholds have not been published. Some analysts estimate the first tier will start near $112,000 for single filers and $224,000 for joint filers, but those are estimates, not official figures.

Here are the confirmed 2026 brackets, which are the best available guide to what the 2027 structure will look like:

There is a separate Part D IRMAA surcharge at the same income tiers, which in 2026 ranges from $14.50 to $91.00 per month. If a life event has reduced your income since the tax year being used, you can ask Social Security to reconsider your bracket.

You cannot negotiate the Part B premium. It is set by CMS and, for most people, deducted straight out of the monthly Social Security payment. There is, however, one common way to reduce what actually leaves your account: a Medicare Advantage plan with a Part B premium reduction, usually marketed as a giveback.

If you want to see how the rest of the plan landscape is shaping up, our guides to Medicare Advantage plans for 2027 and the best Medicare Advantage plans for 2027 cover what is expected to change, and our 2027 costs and benefits by carrier breakdown compares the major national carriers side by side.

Two separate announcements drive what you will actually pay, and they come from two different agencies on two different schedules.

We will update this page as soon as CMS publishes the confirmed 2027 figures. Until then, budget with the projection and leave yourself a little room above it.
