If you're on Medicare, your monthly bill is about to get bigger.
The standard Part B premium for 2025 is $185.00 per month, up from $174.70 in 2024.
That's an extra $10.30 coming out of your Social Security check every month, or about $124 more over the course of the year.
Part B covers doctor visits, outpatient care, lab tests, and preventive services.
Unlike Part A, which is usually free if you worked long enough, Part B always comes with a premium.
Most people have it deducted directly from their Social Security benefits, which means the increase shows up quietly as a smaller deposit rather than a bill in the mailbox.
In 2025 it's $257, up $17 from last year.
That means you pay the first $257 of covered services yourself before Medicare starts picking up its share.
After that, you typically pay 20 percent of the Medicare-approved amount for most services.
If your income tops $106,000 as an individual or $212,000 as a married couple filing jointly, you'll owe an income-related monthly adjustment amount, or IRMAA, on top of the standard premium.
Those surcharges range from about $74 to $443 extra per month depending on how much you earn.
The numbers are based on your tax return from two years ago, so a one-time bump in income can raise your premium even after your situation changes.
Here's where it gets frustrating for retirees on fixed incomes.
Social Security's cost-of-living adjustment for 2025 was 2.5 percent.
For someone collecting $1,900 a month, that's roughly $48 more.
After the Part B increase eats $10.30, the real gain is closer to $38.
Many retirees say the bump feels smaller than the headlines suggest once Medicare takes its cut.
If the higher premium is squeezing your budget, there are a few moves worth checking.
First, look at whether a Medicare Advantage plan in your area offers a lower or zero premium, though you'll want to compare networks and out-of-pocket caps carefully.
Second, if your income dropped recently due to retirement, divorce, or the loss of a spouse, you can file Form SSA-44 to ask Social Security to recalculate your IRMAA.
Third, review your Part D drug plan during open enrollment, since premiums and formularies shift every year.
Open enrollment for Medicare Advantage and Part D runs from October 15 to December 7.
If you're unhappy with your current coverage, that's your window to switch without a medical review.
Miss it and you're generally locked in until the next year.
The bigger picture is that Part B premiums have roughly doubled over the past decade.
That trend isn't likely to reverse as health care costs keep climbing and more boomers join the program.
Our take: the increase stings, but the smartest move is to plan for it every fall rather than get surprised in January.
Check your IRMAA status, shop your drug plan, and run the math before open enrollment closes.

A half hour of comparing options can easily save more than the premium hike costs.
