Here's a number that rarely makes headlines but hits 68 million Americans every single month: the Medicare Part B premium.
In 2025, it's $185.00 per month for most enrollees.
That's up from $174.70 in 2024 — a 5.9% jump.
Meanwhile, the Social Security cost-of-living adjustment for 2025 was just 2.5%.
For millions of retirees, the annual raise in their Social Security check gets partly devoured before it ever lands in the bank.
The premium is typically deducted straight from that monthly payment, so many people never even see the money.
They just notice their deposit didn't grow as much as the news said it would.
Higher earners pay more through the income-related monthly adjustment amount, or IRMAA.
A single filer with income above $106,000 — or a joint filer above $212,000 — gets slapped with a surcharge.
It's based on your tax return from two years ago, which means a one-time windfall like selling a house or cashing out an IRA can raise your premium long after the event.
The part nobody explains at the pharmacy counter: that premium covers only about 20% of most outpatient care.
You're still on the hook for deductibles, coinsurance, and the infamous "donut hole" if you're on Part D drugs.
So the $185 isn't the finish line — it's the entry fee.
Medicare's trustees point to rising health care costs, more expensive drugs, and higher utilization.
But there's a quieter driver too: the program's finances are strained as the population ages.
Fewer workers are paying in relative to the number of people drawing benefits.
Someone has to make up the difference, and right now, that someone is the enrollee.
Not much on the premium itself — it's set annually and applies to nearly everyone.
But you can appeal an IRMAA decision if your income dropped due to a life-changing event like retirement, divorce, or the death of a spouse.
You can also compare Medicare Advantage and Medigap plans during open enrollment, since those costs vary wildly by county and insurer.
The cynical read: this is a slow, automatic wealth transfer from retirees to the health care system, and it happens so quietly that most people just shrug and accept it.
The premium rises, the coverage stays roughly the same, and the shortfall gets papered over with general fund transfers that future taxpayers will inherit.
Our take: Medicare Part B is still a bargain compared to what private insurance would cost a 75-year-old with a pre-existing condition.
But the annual premium creep deserves way more attention than it gets.
Final Thoughts
If your Social Security raise keeps vanishing before you can spend it, you're not imagining things — and you're not alone.
