If you're on Medicare, you've probably noticed that your Social Security check doesn't stretch as far as it used to.
A big reason sits right there on your benefits statement: the Part B premium.
For 2024, the standard monthly premium is $174.70, up from $164.90 last year.
That's about a $10 jump per month, or roughly $120 more over the course of a year.
Here's the part that catches people off guard.
Most beneficiaries don't write a check for that premium.
It gets deducted straight from their Social Security payment before the money ever hits their bank account.
So when the annual cost-of-living adjustment comes through, a chunk of that raise can quietly disappear.
A 3.2% COLA sounds decent until you subtract the higher Part B cost from it.
The premium isn't the same for everyone, either.
If your income crosses certain thresholds, you pay an income-related monthly adjustment amount, or IRMAA.
For 2024, single filers earning above $103,000 and joint filers above $206,000 pay more.
The top tier runs north of $590 a month per person.
The tricky part is that IRMAA is 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.
There is some good news buried in the fine print.
The deductible for Part B dropped slightly to $240 this year, and once you meet it, you typically pay 20% of covered services.
That 20% has no cap, which is why many people pair Original Medicare with a Medigap policy or choose a Medicare Advantage plan.
Those extra plans come with their own costs, so it's worth comparing them side by side rather than assuming one is cheaper.
First, check your Medicare summary notice or log into your MyMedicare account to confirm you're paying the right premium.
If your income dropped because of retirement, divorce, or the death of a spouse, you can ask Social Security to reconsider your IRMAA using a more recent tax year.
That form is called SSA-44, and it's free to file.
Second, treat the premium like any other fixed bill when you budget.
If you're married and both on Medicare, you're looking at roughly $350 a month before any IRMAA.
That's real money, and it's easy to forget because it's invisible on your bank statement.
Some financial planners suggest setting aside a small cushion each month for copays, deductibles, and drug costs so a surprise bill doesn't wreck your month.
Third, if you're still working and nearing 65, pay attention to your timing.
Signing up late can trigger permanent penalties that get added to your premium for as long as you have Part B.
The rules have exceptions for people with employer coverage, but they're specific.
A quick call to your HR department or a State Health Insurance Assistance Program counselor can save you years of overpaying.
The bottom line: Medicare Part B is a bargain compared to most private insurance, but it isn't free, and the cost creeps up every year.
Knowing exactly what you pay and why puts you in a much better spot than finding out the hard way at tax time.
