If you're on Medicare, you already know the drill: the Part B premium comes out of your Social Security check before you ever see it.
In 2025, the standard monthly premium sits at $185, up about $10.30 from last year.
For couples both enrolled, that's roughly $370 a month gone before the first grocery run.
The number that stings more is the annual deductible, which jumped to $257 this year.
That's the amount you pay out of pocket for covered services before Medicare starts chipping in.
Between the premium and the deductible, many retirees are shelling out over $2,400 a year just for the privilege of having Part B coverage.
If your modified adjusted gross income tops $106,000 as an individual or $212,000 filing jointly, you're hit with an income-related monthly adjustment amount, or IRMAA.
Those surcharges range from about $74 extra per month up to roughly $444, depending on your bracket.
The tricky part is that IRMAA is based on your tax return from two years ago, so a one-time bump in income—say from selling a house or cashing out an investment—can raise your premiums long after the event.
Here's where it gets confusing for anyone still working.
If you or your spouse are covered by an employer health plan through active employment, you may be able to delay Part B and skip the premium entirely for now.
But miss that window when you finally retire, and you could face a late enrollment penalty that tacks 10 percent onto your premium for every 12 months you waited.
First, check your Social Security statement or Medicare account to confirm you're being charged the right amount.
If your income dropped recently due to retirement, divorce, or the death of a spouse, you can file Form SSA-44 to request a reduction in your IRMAA.
It's not automatic, and plenty of people never bother—which means they keep overpaying.
Second, compare your options during open enrollment, which runs October 15 through December 7.
A Medicare Advantage plan might bundle in extras like dental or vision, but you'll still pay the Part B premium on top of it.
There's no free lunch here, just different ways of slicing the same bill.
Third, if you're healthy and want to stretch dollars, a high-deductible Medigap plan paired with a Part B deductible that you cover yourself can lower monthly costs.
The trade-off is real: you're betting you won't need much care.
For others, it's a gamble they'd rather not take.
Part B costs have risen most years, and there's no sign that's changing.
If you're planning a retirement budget, build in a cushion of a few hundred dollars a year just for premium increases, because the number you see today won't be the number you pay in five years.
The bottom line: Medicare Part B isn't optional for most people, and the price keeps climbing faster than many fixed incomes can absorb.
Take fifteen minutes this fall to check your bracket, your penalty status, and your plan options.
Final Thoughts
That small bit of homework can be worth hundreds of dollars a year—money that stays in your pocket instead of vanishing from your Social Security check.
