Medicare Part B Costs $202.90 a Month in 2026 — Here's the Math Behind It
The standard Medicare Part B premium is $202.90 a month in 2026 — up $17.90 from $185.00, just under 10 percent — and the annual deductible rises $26 to $283. Set against the 2.8 percent Social Security COLA, the average retired-worker check still rises about $38 a month after the higher premium, but smaller checks give up a larger share of their raise. Beneficiaries with 2024 income above $109,000 single / $218,000 joint pay $284.10 to $689.90 instead. The arithmetic at three benefit levels is below. This is an educational summary, not advice.
Medicare's Part B premium — the monthly charge for doctor visits and outpatient care, deducted from most Social Security checks before anyone sees them — is $202.90 a month in 2026. That is up $17.90 from $185.00 in 2025, an increase of just under 10 percent, and it lands in the same January that Social Security checks rise by a 2.8 percent cost-of-living adjustment. Whether your check goes up, and by how much, is the collision of those two numbers. Here is the arithmetic.
The 2026 Numbers
| Part B Figure | 2025 | 2026 | Change |
|---|---|---|---|
| Standard monthly premium | $185.00 | $202.90 | +$17.90 |
| Annual deductible | $257 | $283 | +$26 |
(CMS 2026 Part B announcement, November 14, 2025, as republished by the Railroad Retirement Board.)
The premium buys the same coverage category as before: physician services, outpatient hospital care, some home health, durable medical equipment. Most people pay it invisibly — it comes out of the Social Security deposit.
The COLA Math: What Your Check Actually Does
The 2026 Social Security COLA is 2.8 percent. For the average retired worker, SSA estimates the January 2026 benefit rises from about $2,015 to $2,071 — a $56 monthly increase. Subtract the $17.90 premium increase and the average net gain is roughly $38 a month. (SSA 2026 COLA fact sheet; CRS Report 94-803.)
The squeeze is proportional, and it lands hardest on smaller checks. Run the same subtraction at three benefit levels:
- $1,200 check: COLA adds $33.60; the premium takes $17.90 — 53% of the raise absorbed.
- $2,015 check (the average): COLA adds $56.42; premium takes $17.90 — 32% absorbed.
- $3,500 check: COLA adds $98.00; premium takes $17.90 — 18% absorbed.
Same premium increase for everyone; very different shares of the raise. This is the structural reason the annual COLA so often feels smaller than the headline.
The Floor Under Your Check
By law, most current beneficiaries cannot have their Part B premium rise by more dollars than their COLA adds — the “hold-harmless” provision, which guarantees the net Social Security check does not shrink from a premium increase. In 2026, with the average COLA increase ($56) comfortably above the premium increase ($17.90), hold-harmless does little visible work for most people. It matters at the margins — and it does not protect everyone. New enrollees, people not yet collecting Social Security (who pay Part B by direct bill), and higher-income beneficiaries paying income-adjusted premiums sit outside the protection. (CMS/RRB 2026 announcement; medicareresources.org.)
Who Pays More Than $202.90
The standard premium applies up to $109,000 of modified adjusted gross income for single filers and $218,000 for joint filers — measured from your tax return two years back, so 2026 premiums look at 2024 income. Above those lines, income-related surcharges (IRMAA) take the total monthly Part B premium from $284.10 up to $689.90 in tiers. (CMS 2026 figures via RRB.) The tiers are cliffs, not slopes — one dollar of income over a threshold repriced the entire year — and one-time events like large Roth conversions or property sales are common, avoidable causes. That mechanism has its own guide: the IRMAA cliff, explained.
What This Does Not Mean
A 9.7 percent premium increase is not a reason to drop or delay Part B — late-enrollment penalties are permanent, and the enrollment window has real teeth. Nor does the $202.90 figure describe your total health-care cost: Part B is one premium among several (Part D, Medigap or Advantage, dental and vision), and the $283 deductible plus 20 percent coinsurance sit underneath it. What the numbers do argue for is planning the income side: which accounts you draw from, and when, decides both the tax bill and — through IRMAA — the Medicare bill two years later.
Frequently Asked Questions
Q: What is the Medicare Part B premium for 2026?
$202.90 per month for most beneficiaries — up $17.90 from $185.00 in 2025. The annual Part B deductible rises $26 to $283.
Q: Will my Social Security check still go up in 2026?
For most people, yes. The 2.8% COLA adds about $56 to the average retired-worker check; after the $17.90 premium increase, the average net gain is roughly $38 a month. Smaller checks keep a smaller share of their raise.
Q: Who pays more than the standard premium?
Beneficiaries whose modified adjusted gross income two years prior exceeded $109,000 (single) or $218,000 (joint). Income-adjusted premiums run from $284.10 to $689.90 per month in 2026, in tiers that apply fully once a threshold is crossed by any amount.
Q: Can my check shrink because of the premium increase?
Generally no — the hold-harmless rule caps most current beneficiaries' premium increase at their dollar COLA amount. It does not cover new enrollees, people not yet drawing Social Security, or those paying income-adjusted premiums.
