Start with two numbers. The Medicare Part B standard premium goes from $185 a month in 2025 to $202.90 in 2026. The Social Security cost-of-living adjustment, or COLA, for 2026 is 2.8 percent. One number goes up on your bill. The other goes up on your check. They do not arrive as separate events.
Think of a rent notice that raises your rent the same month your employer gives you a raise. You still count the raise. You just count it after rent. For most retirees, Part B works the same way, because the premium is usually deducted from the Social Security payment before the money lands in the bank account.
What the 2026 numbers show
The jump is $17.90 per month, about 10 percent. Over a year, the standard premium tops $2,400. The Centers for Medicare & Medicaid Services (CMS) released the 2026 Part A and Part B amounts on November 14, 2025, and AARP confirms the $202.90 figure.
The Center for Retirement Research estimates the increase uses up more than a quarter of the COLA. It also finds that Part B premiums reach an all-time high of 9.4 percent of the average retired worker's annual benefit in 2026. That is why a 2.8 percent headline can feel thinner at the mailbox. Month over month, the raise shows up. A slice of it leaves at the same time.
Why the premium is rising
Part B covers outpatient care. That means doctor visits, hospital outpatient services, diagnostic tests and drugs given by a physician. The premium is set to cover about 25 percent of estimated Part B spending. General federal revenue pays for the rest. When outpatient costs climb, the premium follows.
Part A, which covers hospital stays, is mostly paid for through the payroll tax. About 99 percent of beneficiaries owe no Part A premium because they have at least 40 quarters of Medicare-covered work. Still, the inpatient hospital deductible rises to $1,736 in 2026, up $60. Daily coinsurance for hospital days 61 through 90 is $434, and skilled nursing coinsurance for days 21 through 100 is $217 per day. The numbers are modest next to a hospital bill. They are not small next to a fixed income.
The COLA runs on a different clock. It is tied to a separate inflation measure, not to medical program costs. When health premiums outpace that measure, the net gain shrinks. Skepticism is fair here, but the arithmetic is simple, and it is worth doing before assuming the published percentage is the whole story.
Income-related premiums and other deductions
Not everyone pays $202.90. For 2026, a couple with annual income of $218,000 or less pays the standard amount. Higher earners pay more, up to $689.90 per month for a couple with $750,000 or more. Which tier applies depends on income reported to the Social Security Administration, so the record behind it matters.
The Part B deductible is $283 for 2026. Part D drug plans add another layer: a plan premium that varies by plan, plus an income-related amount that can come straight out of a Social Security benefit. Many people also buy supplemental insurance, which has its own premium. Add these up and the monthly medical deduction can run well above the Part B line alone. Read the deductions on the benefit statement, not only the COLA percentage.
Questions to ask when reviewing your own budget
A plain starting point is subtraction. Take the monthly benefit after the 2.8 percent COLA. Subtract the new Part B premium. Compare that with last year's net amount. The gap shows how much of the raise is left. Think of it as the difference between the sticker price and the receipt total in a grocery aisle.
- Is my Part B premium the standard amount or an income-related one?
- Am I paying a Part D income-related premium out of my check?
- Which costs sit outside Medicare altogether?
That last question matters. Medicare does not cover dental, vision or hearing care. It generally does not cover long-term care, apart from limited skilled nursing time after a hospital stay. A budget that assumes otherwise may come in low.
The public sources reviewed here leave some gaps. They do not say whether any protection limits how much a Part B increase can cut into a benefit increase, or how that would apply to one person. They also give no 2027 COLA or premium figures, so plans should not lean on guesses about next year. This article is educational only and is not personal financial advice.
