What Medicare Part B costs in 2026
The standard Medicare Part B premium is $202.90 a month in 2026, up $17.90 from $185.00 in 2025, with a $283 annual deductible.
The 2026 standard premium at a glance
Most people pay exactly that. About 8% pay more because of income; some pay nothing because a state program covers it. Part B is only one of five separate Medicare bills, so it isn’t your total cost.

The full 2026 Part B numbers, and what changed
Every Part B cost that changed this year:
Premium, deductible and coinsurance for 2026
| Medicare cost | 2025 | 2026 | Key detail |
|---|---|---|---|
| Standard monthly premium | $185.00 | $202.90 | Up $17.90, or 9.7% |
| Annual Part B deductible | $257 | $283 | Up $26 |

Source: Centers for Medicare & Medicaid Services, 2026 Medicare Parts A & B premiums and deductibles, published November 14, 2025.
After the deductible you generally pay 20% coinsurance on covered services, with no annual cap.
Why the premium rose 9.7%
CMS attributes it to projected price changes and assumed utilization increases consistent with historical experience.
📊 Data Point: At the standard rate, Part B costs $2,434.80 in premiums across 2026, plus the $283 deductible — $2,717.80 before a single coinsurance dollar. Calculated from CMS 2026 figures.
How much of your Social Security raise Part B takes
The premium increase takes about 32% of the average retiree’s raise this year.
The arithmetic on the average check
🔍 How It Works: The 2026 cost-of-living adjustment was 2.8%. Social Security and Medicare land in the same deposit, so the two changes net against each other.
- Average retired-worker benefit before the COLA: $2,015
- After the 2.8% COLA: $2,071 — a raise of $56
- Part B premium increase: $17.90
- Net raise: $38.10 — an effective increase of 1.9%, not 2.8%
Benefit figures: Social Security Administration 2026 COLA fact sheet. Premium increase: CMS. The $56, $38.10 and 1.9% lines are our calculation from those two sources.
How to run the same numbers on yours
Those are national averages for the average Social Security benefit. Subtract $17.90 from your own COLA increase, then divide by your old benefit; our Social Security calculator gives the starting figure.
Part B now takes 9.8% of the average 2026 check.
Who pays more than $202.90 in 2026
A modified adjusted gross income above $109,000 single or $218,000 joint triggers an income-related monthly adjustment amount, which CMS says affects about 8% of enrollees.

Which year’s income sets your 2026 premium
Your 2024 return does. Social Security works from income two years back, starting with adjusted gross income on line 11 plus tax-exempt interest, and whether your Social Security is taxable feeds in.
These are cliffs, not phase-ins. One dollar over $109,000 costs $1,148.40 a year in Part B and Part D surcharges combined.
When you can ask Social Security to lower it
Only a qualifying life-changing event — retirement, divorce, a spouse’s death — lets Social Security use a more recent year, through its process for requesting a lower IRMAA. A one-time capital gain is not on the list.
✅ Action Step: Before your next asset sale or Roth conversion, ask a CPA: “Which IRMAA tier does this put me in two years from now?”
Who pays less than $202.90, and how to qualify
If $202.90 is out of reach, help exists — and most eligible people never claim it.
Why the hold harmless rule rarely helps in 2026
The hold harmless provision caps your Part B increase at your COLA increase, so an existing check cannot fall. This year the average $56 COLA exceeded the $17.90 rise, so almost nobody is protected.
Congressional Research Service analysis names four groups it never covers: people whose premiums Medicaid pays, IRMAA payers, people whose premiums aren’t deducted from Social Security, and new enrollees.
Programs that pay the Part B premium for you
Three Medicare Savings Programs — QMB, SLMB and QI — can pay the premium outright. They run through state Medicaid agencies, limits vary by state, and enrolling also unlocks Extra Help for drug costs.
✅ Action Step: Ask your state Medicaid office or a free State Health Insurance Assistance Program counselor: “Do I qualify for QMB, SLMB or QI, and can coverage be backdated?” Apply even if you think you earn too much.

How the premium gets paid, and what late enrollment costs
How you pay depends on whether your benefits have started.
If you already collect Social Security
The premium deduction comes straight out of your monthly benefit.
If you don’t collect Social Security yet
Medicare bills you directly, usually quarterly, and Medicare Easy Pay can debit your account. This catches people who delay claiming Social Security but enroll at 65 — a bill arrives, not a deduction. Once you apply, billing switches over.
What the late enrollment penalty adds
🔍 How It Works: Medicare adds 10% of the standard premium for each full 12-month period you could have had Part B and didn’t, rounded to the nearest $0.10, permanently.
- One full year late, at 2026 rates: about $20.30 a month
- Two full years late: about $40.60 a month, roughly $487 a year

Four things people get wrong about the 2026 increase
These costly mistakes show up every January.
⚠️ Costly Mistake: Assuming $202.90 covers your Medicare. It covers the Part B premium only — the $283 deductible, 20% uncapped coinsurance and drug coverage sit on top. A Medicare Advantage plan doesn’t replace it; you keep paying.
Three more. Hold harmless probably isn’t protecting you, for the reasons above. An IRMAA appeal needs a qualifying event, which excludes a Roth conversion. And waiting to enroll costs about $20.30 a month, permanently, per year of delay.
