How Medicare Part B Premium Hikes Can Shrink Your Social Security Raise

Medicare Part B is one of the few retirement costs you can't shop around. It comes out of your Social Security check before the money reaches your bank account. When the premium rises, your deposit can shrink even in a year when your benefit goes up.

According to the Centers for Medicare & Medicaid Services (CMS), Part B pays for physicians' services, outpatient hospital care, durable medical equipment, certain home health services, and certain other medical services. In plain terms, it covers the routine doctor visits and tests most retirees use every year. The premium is due whether or not you see a doctor.

Medicare covers more than 70 million people, including adults 65 and older and younger adults with long-term disabilities. KFF notes that beneficiaries generally pay out of pocket for premiums, deductibles, and cost sharing. It also reports that premiums and cost sharing have risen steadily in recent years and are projected to keep growing over the next decade.

Reading the 2026 Premium Increase

For 2026, the standard Part B premium is $202.90 per month, up from $185.00 in 2025. That is an increase of about 10 percent. KFF puts the yearly cost at more than $2,400. That figure is simple arithmetic, twelve months at $202.90 comes to about $2,435. For a couple who both enroll, the same math gives roughly $4,870 a year before any other medical spending.

CMS released the 2026 amounts on November 14, 2025. The timing matters. Many households have already settled their next-year budget by then. Put the November announcement on your calendar and revisit your numbers when it lands.

Looking ahead, AARP reports that the Part B premium may rise again in 2027. The source excerpts reviewed here do not give a 2027 figure. Until one is published, test your budget against a few possible increases rather than a single guess.

Higher Incomes Pay More

The standard premium is not what everyone pays. Higher-income beneficiaries owe an income-related monthly adjustment amount, known as IRMAA. According to KFF, individuals with incomes above $109,000 pay an income-related premium that phases up to $689.90 per month in 2026. The full bracket schedule is not reproduced here, so check the current tiers with the Social Security Administration (SSA) or CMS before you rely on a number.

Income-based premiums usually rest on an older tax return, not this year's income. SSA can confirm which tax year it is using for you. That matters if you sell a home, take a large retirement withdrawal, or close a business. Any of those could raise your income for a year, and the premium effect may show up later. If your income has dropped since that return, SSA can explain what options exist and how to ask for a review.

How a Premium Increase Eats Into a COLA

Social Security cost-of-living adjustments (COLAs) are meant to help benefits keep pace with prices. But because Part B is commonly withheld from the monthly benefit, a premium increase can take back part of the raise. SmartAsset discusses how a Part B increase affects the way a COLA is experienced.

Here is a hypothetical example, not 2026 data. Say your benefit rises by $40 a month and your Part B premium rises by $18. Your deposit grows by only $22. Then the grocery bill and the property tax bill go up too. The raise you expected feels much smaller.

Check your own numbers in three steps:

1. Find your SSA benefit notice for the new year, or sign in to your my Social Security account.
2. Compare the gross benefit, the Medicare premium withheld, and the net deposit.
3. Set your monthly budget to the net deposit, not the gross amount.

Building a Budget That Absorbs Medical Cost Growth

Start with a dedicated line for Part B. Keep it separate from any supplemental coverage, prescription costs, and direct medical bills. When the line is separate, you can see exactly how much it moves each year.

Next, build a cushion. A cash reserve for medical costs lets you absorb a premium jump or an unexpected bill without selling investments at a bad time. How large the reserve should be depends on your health, your coverage, and your other income, so there is no single right number.

• Use the net deposit: Budget from what actually lands in your account.
• Model a range for 2027: Try a few increases, since no 2027 figure is confirmed in the sources reviewed.
• Revisit in November: CMS has released each year's amounts in the fall, and the 2026 figures came out November 14, 2025.

Part A is a separate matter. CMS says about 99 percent of beneficiaries pay no Part A premium because they have at least 40 quarters of Medicare-covered employment. A reduced Part A premium of $311 per month applies in 2026 for those with 30 or more quarters, and the full premium is $565. Those numbers affect only a small group, but they are worth checking if your work history is short.

What the Sources Do Not Settle

The sources reviewed for this article do not give the 2026 Part B deductible or coinsurance rate. Look up both in the current CMS fact sheet or on Medicare.gov before you finalize a budget. They also do not cover how to appeal an income-related premium decision, or how Medigap and other coverage change out-of-pocket costs.

The longer-term picture is also uncertain. KFF's summary of the June 2026 Medicare Trustees Report says the Part A trust fund is projected to be depleted in 2033, one quarter earlier than last year's projection. That does not change what you owe this year. It does suggest that Medicare costs and rules will keep changing.
