Medicare's open enrollment window is open, and millions of Americans on fixed incomes are staring down a number that keeps climbing: the standard Part B premium.
For 2025, most beneficiaries pay $185.00 per month, up about $9.80 from last year.
That's roughly $2,220 a year, and it typically comes straight out of a Social Security check before the money ever hits a bank account.
The squeeze is real because Social Security's cost-of-living adjustment is designed to keep pace with inflation, but it doesn't always match the rising cost of the things retirees actually buy.
A 2.5 percent bump in benefits can vanish quickly when premiums, supplemental insurance, and Part D drug plan costs all rise at once.
Many people open their January statement and wonder why their deposit barely budged.
There's a catch that trips up higher earners too.
If your modified adjusted gross income crosses certain thresholds, you pay an income-related monthly adjustment amount, or IRMAA.
That can push the Part B premium well past $600 a month for top earners.
The thresholds are based on tax returns from two years prior, so a one-time windfall like selling a house or cashing out an investment can raise your premium long after the event.
For most people, the premium is deducted automatically, which means they never see the full benefit amount and can lose track of what's actually being taken out.
That makes it harder to compare plans or notice when a supplement insurer quietly raises rates.
Financial advisers suggest reviewing your Medicare Advantage or Medigap options every fall rather than defaulting to whatever plan you already have.
The math matters most for the roughly half of beneficiaries who live on less than $30,000 a year.
For them, an extra $10 a month is not abstract.
It's a skipped prescription, a shorter grocery list, or one less tank of gas.
Programs like Medicare Savings Programs and Extra Help exist to cover some of these costs, but enrollment is notoriously low because the applications are confusing and many people assume they earn too much to qualify.
One practical step: check whether your state offers a Medicare Savings Program, which can pay the Part B premium for people under certain income limits.
You can apply through your state Medicaid office, and the thresholds are higher than many people expect.
Even if you think you won't qualify, a five-minute call can answer the question for good.
Our take: Part B is not optional for most retirees, and the annual increases are not going away.
The smartest move is to treat open enrollment like a yearly bill review, not a formality.
