Medicare Part B Costs in 2026: The $202.90 Premium, the $283 Deductible and What Reaches Your Check
The standard Medicare Part B premium is $202.90 a month in 2026, up $17.90 from $185.00, and the annual deductible is $283, up $26. After the 2.8 percent Social Security COLA, the average retired worker still nets about $38 more a month. Beneficiaries whose 2024 income exceeded $109,000 single or $218,000 joint pay $284.10 to $689.90.
For most retirees, the Part B premium is a number they never see written on a check. It is withheld from the Social Security deposit before the money arrives, so the only visible sign of a premium increase is a raise that turns out smaller than announced. In 2026 the premium rose by just under 10 percent in the same month benefits rose by 2.8 percent. The two figures are easy to find; what they do to a particular household is not. That is what this guide works through.
What follows is educational. Individual premium notices come from Social Security, and specific questions about a determination should go to Social Security or Medicare directly.
What the Part B Question Is Really Asking
“What does Part B cost?” usually means one of three things:
- The fixed cost: the monthly premium, paid whether or not any care is used.
- The usage cost: the annual deductible and the coinsurance owed on care received.
- The net effect: how the premium change compares with the year’s Social Security increase, which decides whether the deposit rises or stays flat.
A fourth question applies only to higher-income households: whether an income-related surcharge applies on top of the standard premium.
The 2026 Figures
| Part B figure | 2025 | 2026 | Change |
|---|---|---|---|
| Standard monthly premium | $185.00 | $202.90 | +$17.90 (9.7%) |
| Standard premium, annualized | $2,220.00 | $2,434.80 | +$214.80 |
| Annual deductible | $257 | $283 | +$26 |
(CMS, 2026 Parts A & B fact sheet)
CMS attributes the increase mainly to projected price changes and assumed increases in use of services consistent with historical experience. (CMS, 2026 Parts A & B fact sheet) Part B covers physician services, outpatient hospital care, some home health care and durable medical equipment. After the deductible, the beneficiary generally pays 20 percent of the Medicare-approved amount for most covered services. (Medicare.gov, Medicare costs)
How the Premium Is Set
The standard premium is not negotiated or bid. It is fixed by formula at 50 percent of the monthly actuarial rate for enrollees 65 and older, a level designed to cover roughly a quarter of average Part B costs per enrollee, with federal general revenue paying the rest. (42 U.S.C. §1395r) Higher-income beneficiaries pay a larger share of program cost, set by statute at 35, 50, 65, 80 or 85 percent depending on income. (42 U.S.C. §1395r) Measured against the 2026 standard premium, the published tier amounts follow those ratios:
| Share of program cost | Ratio to the standard premium | 2026 total Part B premium |
|---|---|---|
| 25% (standard) | 1.0× | $202.90 |
| 35% | 1.4× | $284.10 |
| 50% | 2.0× | $405.80 |
| 65% | 2.6× | $527.50 |
| 80% | 3.2× | $649.20 |
| 85% | 3.4× | $689.90 |
(Premiums: CMS, 2026 Parts A & B fact sheet. Shares: 42 U.S.C. §1395r.)
The structure explains why every tier moves when the standard premium moves: a 9.7 percent rise in the base carries through to each income tier.
The Net Effect on the Social Security Check
The 2026 cost-of-living adjustment is 2.8 percent. SSA estimates the average retired-worker benefit rose from about $2,015 to $2,071 a month in January 2026, an increase of $56. (SSA, 2026 COLA fact sheet) Subtract the $17.90 premium increase and the average retiree nets about $38 a month more.
Because the COLA is a percentage and the premium increase is a flat dollar amount, the premium takes a larger bite from smaller checks.
| Monthly benefit before the COLA | 2.8% COLA | Premium increase | Net monthly change | Share of the raise absorbed |
|---|---|---|---|---|
| $1,200 | $33.60 | $17.90 | +$15.70 | 53% |
| $2,015 (average) | $56.42 | $17.90 | +$38.52 | 32% |
| $3,500 | $98.00 | $17.90 | +$80.10 | 18% |
This is the arithmetic behind the common sense that the annual COLA feels smaller than its headline, and why it feels smallest to those with the smallest benefits.
$17.90 of new premium against a 2.8 percent raise. On a $1,200 check, the premium takes 53 percent of the increase; on a $3,500 check, 18 percent.
The Hold-Harmless Floor
Federal law prevents a Part B premium increase from shrinking most beneficiaries’ net Social Security payment. For a person who received benefits for November and December of the prior year with the premium deducted from them, the premium cannot rise by more than the dollar amount of that person’s COLA. (42 U.S.C. §1395r) The net deposit can stay flat; it cannot fall because of the premium.
In 2026, with the average COLA of $56 well above the $17.90 premium increase, the floor does little visible work for most people. It matters for small benefits. The break-even is $17.90 ÷ 2.8% ≈ $639 a month: below that, the COLA adds less than $17.90, and the floor applies.
The protection has clear limits. It does not cover:
- New enrollees, who did not have the premium deducted from benefits in the prior November and December.
- People not yet collecting Social Security, who pay Part B by direct bill.
- Higher-income beneficiaries whose premium includes an income-related adjustment; the statute excludes them explicitly. (42 U.S.C. §1395r)
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 on the tax return from two years earlier, so 2026 premiums use 2024 income. (CMS, 2026 Parts A & B fact sheet; 20 CFR §418.1135) Above those levels, the income-related monthly adjustment amount, or IRMAA, raises the total monthly Part B premium to between $284.10 and $689.90, in tiers. Each tier applies in full once income passes its threshold by any amount, and one-time events such as large Roth conversions or property sales are frequent causes. The mechanics have their own guide, the IRMAA cliff.
Because the look-back is two years, the first premiums after retirement are often priced on a working year’s income. A beneficiary whose income has fallen because of a qualifying event, such as stopping work, a spouse’s death or divorce, can ask Social Security on Form SSA-44 to use a more recent year. (20 CFR §418.1205)
A Hypothetical Household, Worked Through
This illustration is hypothetical and simplified. It is not based on any client and is not a recommendation. Benefit figures are illustrative.
Consider a married couple, both 72, both on Medicare since 2019 with premiums deducted from Social Security. Before the COLA, one spouse’s benefit is $2,600 a month and the other’s is $1,300. Their 2024 joint MAGI was $140,000, well under the $218,000 threshold.
| Spouse | 2.8% COLA | Premium increase | Net monthly change |
|---|---|---|---|
| Higher earner ($2,600) | $72.80 | $17.90 | +$54.90 |
| Lower earner ($1,300) | $36.40 | $17.90 | +$18.50 |
| Household | $109.20 | $35.80 | +$73.40 |
For the year, the couple’s Part B premiums and deductibles come to ($202.90 × 12 + $283) × 2 = $5,435.60, compared with ($185.00 × 12 + $257) × 2 = $4,954.00 in 2025, an increase of $481.60. The premium increase absorbs about a third of the household’s COLA ($35.80 of $109.20).
Two variations
- If 2024 income had been higher. At $230,000 of 2024 MAGI, each spouse would pay $284.10 instead of $202.90. That adds $81.20 × 2 × 12 = $1,948.80 a year in Part B surcharges alone, before any Part D surcharge, and removes the hold-harmless protection.
- If one benefit were very small. A person with a $500 benefit whose $185.00 premium was deducted from benefits in late 2025 receives a COLA of $500 × 2.8% = $14.00. Under the hold-harmless rule, that person’s premium can rise by no more than $14.00, to $199.00 rather than $202.90, and the net deposit stays level.
How We Approach This in a Plan
We carry Medicare premiums in the retirement budget as a cost that grows faster than general inflation in some years, and we plan the income side with them in mind.
- Social Security. Premiums are netted against benefits, so the claiming decision and the Medicare decision are made together; see our Social Security claiming strategy guide and the 2026 COLA guide.
- Income two years out. Every conversion, gain and distribution is priced for its effect on premiums two years later, using the tiers in our Medicare and IRMAA guide.
- Withdrawal order. Which accounts fund spending, and in what order, sets taxable income and therefore premiums; the framework is in the order in which you draw down accounts.
- Enrollment timing. A higher premium is never a reason to delay Part B without qualifying coverage; the permanent penalties are laid out in our guide to Medicare’s seven-month window.
Questions Worth Answering Before You Decide
- What did the Social Security notice show for this year’s gross benefit, premium and net payment?
- Was the premium deducted from benefits last November and December, so the hold-harmless floor applies?
- What was MAGI on the return two years ago, and how close was it to $109,000 or $218,000?
- Has income fallen since then because of a qualifying event that supports an SSA-44 request?
- What will this year’s income decisions do to premiums two years from now?
- Beyond Part B, what are the household’s Part D, Medigap or Advantage, dental and vision costs?
What This Does Not Mean
- It does not mean Part B should be dropped or delayed. Late-enrollment penalties are permanent unless another qualifying exception applies.
- It does not describe total health-care cost. Part B is one premium among several, and the $283 deductible and 20 percent coinsurance sit beneath it.
- It does not mean every check shrinks. For most people receiving benefits, the COLA exceeds the premium increase, and the hold-harmless rule protects many of the rest.
- It is not personalized advice. Premium determinations and appeals belong with Social Security, and income planning with a tax professional.
Frequently Asked Questions
Q: What is the Medicare Part B premium for 2026?
$202.90 a month for most beneficiaries, up $17.90 from $185.00 in 2025. The annual Part B deductible is $283, up $26.
Q: Will my Social Security check still rise in 2026?
For most people, yes. The 2.8 percent COLA adds about $56 to the average retired-worker benefit, and after the $17.90 premium increase the average net gain is about $38 a month. Smaller benefits keep a smaller share of the raise.
Q: Who pays more than the standard premium?
Beneficiaries whose modified adjusted gross income two years earlier exceeded $109,000 single or $218,000 joint. Their 2026 Part B premiums range from $284.10 to $689.90 a month, in tiers that apply in full once a threshold is crossed.
Q: Can a Part B premium increase reduce my Social Security payment?
Generally not, if your premium was deducted from benefits in the prior November and December. The hold-harmless rule limits the increase to your COLA in dollars. It does not cover new enrollees, people billed directly, or those paying an income-related surcharge.
Q: What does Part B cost when I use care?
After the $283 deductible, you generally pay 20 percent of the Medicare-approved amount for most covered services.
Q: How is the standard premium calculated?
By formula: 50 percent of the monthly actuarial rate for enrollees 65 and older, roughly a quarter of average Part B costs per enrollee. Higher-income beneficiaries pay 35 to 85 percent of program cost.
