Most people come to Medicare expecting one number. One bill. One monthly charge that’s simple and predictable. What they find instead is a system with four parts, multiple premium tiers, income adjustments, and a dizzying array of supplemental options that can make your total monthly cost anywhere from almost nothing to well over $500. That gap is real, and it’s why so many people feel blindsided.
You might be wondering: “Okay, but what will I actually pay?” Here’s what I tell people when they sit down with me for the first time: the answer depends on which parts of Medicare you have, what your income was two years ago, and whether you’ve bought any additional coverage. Let me walk you through each layer, because once you see the full picture, it starts to make sense.
The good news is that most people pay less than they expect for the basics. The part that catches people off guard is everything layered on top.
- Most people pay $185/month for Medicare Part B in 2026 (higher earners pay more).
- Part A (hospital) is free for most people who worked 40+ quarters; others pay up to $518/month.
- Medicare Advantage plans can have $0 premiums but often come with copays and network restrictions.
- Medigap (supplement) plans typically add $100-$300+/month but can dramatically reduce out-of-pocket costs.
- Your total monthly Medicare cost in 2026 can range from roughly $0 to $600+ depending on your situation.
The Parts and What They Actually Cost
Let me start with the building blocks, because this is where a lot of confusion lives.
Part A covers hospital stays, skilled nursing facilities, and some home health care. If you or your spouse worked and paid Medicare taxes for at least 40 quarters (that’s 10 years), you don’t pay a premium for Part A at all. Most people qualify. If you have between 30 and 39 quarters, your Part A premium in 2026 is $284 per month. Fewer than 30 quarters and you’re looking at $518 per month. That’s a significant cost that surprises people who spent time self-employed or working outside the U.S.
Part B is where almost everyone pays something. The standard Part B premium in 2026 is $185 per month. That’s deducted automatically from your Social Security check if you’re receiving benefits, which most people are. If you’re not yet taking Social Security, Medicare bills you quarterly instead, and I’ve seen that catch people off guard when a $555 bill shows up.
Part D covers prescription drugs. Premiums vary by plan and where you live, but the national base beneficiary premium is around $36 per month in 2026. Your actual premium could be higher or lower depending on which plan you choose.
Here’s the table I wish someone had handed me when I first started doing this work:
| Medicare Part | What It Covers | 2026 Monthly Premium (typical) |
|---|---|---|
| Part A | Hospital, skilled nursing, some home health | $0 (most people); up to $518 |
| Part B | Doctor visits, outpatient, preventive care | $185 standard |
| Part C (Medicare Advantage) | Combines A+B (and usually D) | $0 to $100+ |
| Part D | Prescription drugs | ~$0 to $100+ depending on plan |
| Medigap (Supplement) | Fills gaps in Original Medicare | ~$80 to $300+ |
IRMAA: The Income Surcharge Nobody Warns You About

This one is genuinely frustrating, and I say that as someone who has watched good people get blindsided by it year after year. If your modified adjusted gross income from two years prior exceeds certain thresholds, you pay more for Part B and Part D. This surcharge is called IRMAA (Income-Related Monthly Adjustment Amount), and it’s calculated based on your tax return from 2024 when you’re enrolling in 2026.
The tiers in 2026 look like this:
| Individual Income (2024) | Joint Income (2024) | Part B Monthly Premium |
|---|---|---|
| Up to $106,000 | Up to $212,000 | $185.00 |
| $106,001 to $133,000 | $212,001 to $266,000 | $259.00 |
| $133,001 to $167,000 | $266,001 to $334,000 | $370.00 |
| $167,001 to $200,000 | $334,001 to $400,000 | $480.90 |
| $200,001 to $500,000 | $400,001 to $750,000 | $591.90 |
| Above $500,000 | Above $750,000 | $628.90 |
Part D also has IRMAA surcharges on top of your plan premium, ranging from about $13 to $81 extra per month at the higher tiers.
If you had a one-time income event (sold a house, took a large IRA distribution, retired mid-year), you may qualify for an IRMAA appeal using Form SSA-44. I’ve helped people save hundreds of dollars a month this way. It’s not automatic; you have to file it yourself. The Centers for Medicare & Medicaid Services explains the appeal process, and it’s worth doing if your income dropped significantly.
Original Medicare vs. Medicare Advantage: The Real Trade-Off
Medicare Part B Premium Cost - Shocking! What is IRMAA? · Medicare on Video - Medicare Specialist on YouTube
Lots of people ask me which is better. Honestly, there isn’t a universal right answer, and anyone who tells you otherwise is oversimplifying. But here’s my honest take after two decades of this work.
Original Medicare (Parts A + B) gives you the widest access to doctors and hospitals in the country. Almost every provider accepts it. You pay your Part B premium, your deductibles (the Part A hospital deductible is $1,676 per benefit period in 2026, and the Part B deductible is $257 for the year), and then coinsurance on most services. The catch: there’s no out-of-pocket maximum. A bad year can cost you tens of thousands. That’s why many people add a Medigap supplement plan.
Medicare Advantage (Part C) is run by private insurers. Many plans advertise $0 premiums, which sounds great until you realize you still pay your Part B premium on top of it. Advantage plans typically have copays, prior authorization requirements, and network restrictions. The AARP Medicare resource center has solid comparison tools that can help you look at specific plans in your zip code.
Here’s a worked example that illustrates the difference:
Margaret, 68, from Phoenix, has the standard Part B income bracket. She chose a $0-premium Medicare Advantage plan and pays $185/month in Part B premiums. She has a knee replacement and faces a $3,400 out-of-pocket maximum under her plan. Total that year: roughly $2,220 in premiums + $3,400 in cost-sharing = $5,620.
Her neighbor Eleanor chose Original Medicare + Medigap Plan G at $195/month + a Part D plan at $42/month. Eleanor also had the knee replacement. She paid the $257 Part B deductible, then Plan G covered everything else. Total: ($185 + $195 + $42) x 12 + $257 = $5,297. Similar total cost, but Eleanor had zero surprise bills and could see any surgeon she wanted.
That’s the trade-off in concrete terms.
What Medigap Actually Adds to Your Monthly Bill
Medigap plans are sold by private insurers, but they’re standardized by the federal government. A Plan G from one company covers the same things as a Plan G from another. What varies is the premium.
In 2026, a 65-year-old woman in good health in a mid-sized city might pay around $120 to $165 per month for Plan G. A 72-year-old man in a high-cost state like New York might pay $280 or more. Prices vary by age, sex, tobacco use, and location. The open enrollment window right when you turn 65 and enroll in Part B is the only time insurers must accept you regardless of health. Miss that window and you could be denied coverage or charged significantly more based on your medical history.
Plan G is what I usually point people toward these days. Plan F (the old favorite) was eliminated for new enrollees in 2020, and Plan G covers everything F did except the Part B deductible, which is only $257 a year. The premium difference between F and G is almost always larger than $257. Do the math and G usually wins.
Low-Income Help: Programs That Can Reduce Your Costs to Nearly Zero
If your income and assets are below certain limits, you may qualify for programs that dramatically reduce or eliminate your Medicare costs. Extra Help (also called the Low Income Subsidy, or LIS) can lower your Part D drug costs significantly, sometimes to a few dollars per prescription. Medicaid, for those who qualify, can cover Part B premiums and cost-sharing entirely.
A worked example: Robert, 70, single, lives in Ohio on $1,400/month Social Security. He qualifies for Extra Help on Part D and a Medicare Savings Program that pays his $185 Part B premium. His effective monthly Medicare cost: close to $0. A lot of people in this situation don’t know these programs exist until someone tells them. Please look them up at Medicare.gov or call 1-800-MEDICARE.
