How Much Does Medicare Cost? Complete 2026 Breakdown

Let's skip the preamble and get right to the number that matters: how much is Medicare going to cost you this year?

The honest answer is it depends — but not in the way that's usually an excuse to avoid giving a real number. It depends on your income, your health, which coverage path you choose, and whether you know about the programs that can slash your costs in half. This guide gives you actual dollar figures for every scenario.

Here's the floor: if you're healthy, have typical retirement income below $109,000 a year, and pick a zero-premium Medicare Advantage plan, you could spend as little as $2,435 to $3,800 a year on Medicare — mostly out-of-pocket costs when you actually use healthcare. If you have chronic conditions, see multiple specialists, and end up hospitalized? Original Medicare alone, without a supplement, could hit you for $10,000 or more in a single bad year.

And if you earn $200,000 in retirement income? You're paying IRMAA surcharges that add hundreds of dollars a month on top of the standard premium. That's a cost most people never see coming until it shows up on their Social Security deduction.

So the range for a real person in 2026 is roughly $2,400 to $20,000+ annually depending on those variables. The rest of this guide breaks down exactly where every dollar goes — and how to keep that number as low as possible.

Most people pay $0 for Part A. That's the headline, and it's mostly true — if you or your spouse worked and paid Medicare taxes for at least 40 quarters (10 years), your Part A premium is zero. About 99% of Medicare enrollees qualify this way.

But there's a Part A premium if you didn't hit that threshold. Work 30-39 quarters and you'll pay $285/month in 2026. Fewer than 30 quarters? The premium jumps to $518/month. These numbers apply to a small slice of people — mostly immigrants who worked in the US for fewer than 10 years — but if that's your situation, it's a significant cost that gets overlooked.

The Part A costs that hit nearly everyone, premium-free or not, are the cost-sharing charges when you actually use the hospital.

**The Part A Hospital Deductible**

The Part A inpatient deductible for 2026 is $1,736. This isn't an annual deductible like most insurance. It's a per-benefit-period deductible, which is one of the weirder quirks of Medicare's structure. A benefit period starts when you're admitted to a hospital or skilled nursing facility, and ends when you've been out for 60 consecutive days. Theoretically, if you're admitted twice in a year with a 60+ day gap in between, you pay that $1,736 twice.

For most people, one hospitalization per year is the realistic scenario. So budget $1,736 as the potential hit if you end up inpatient.

**Coinsurance: Days 61 Through 90**

Days 1-60 are covered after that deductible. Days 61-90 start costing $434 per day. That's hospital coinsurance you pay out-of-pocket every single day in that range. A week in the hospital between day 61 and day 90 is $3,038 on top of your deductible.

Days 91 and beyond tap into your lifetime reserve days — 60 days total over your lifetime, not renewable. Using lifetime reserve days costs $868 per day. After your 60 lifetime reserve days are gone, Original Medicare pays nothing for extended hospital stays. That's not a hypothetical risk. It's the reason Medigap exists.

**Skilled Nursing Facility (SNF) Coinsurance**

Medicare covers SNF care fully for the first 20 days after a qualifying 3-day inpatient hospital stay. Days 21-100 cost $217.50 per day in 2026. After 100 days, Medicare pays nothing. An extended nursing home stay is essentially uncovered by Original Medicare — another thing people discover at the worst possible moment.

**What Part A Actually Costs You in a Typical Year**

If you stay healthy and never get admitted: $0. One typical hospitalization under 60 days: $1,736. Moderate hospitalization (say, 10 days): $1,736 deductible. Serious hospitalization (75 days, tapping days 61-90): $1,736 + (30 days × $434) = $14,756.

That last number is what people aren't prepared for. It's the scenario where having a Part A supplement or Medicare Advantage with a MOOP becomes financially critical.

Part B is where most Medicare enrollees feel the cost most directly because it comes out of your Social Security check every month — or you pay it directly if you're not drawing Social Security yet.

The standard Part B premium for 2026 is $202.90 per month. That's $2,434.80 per year just for Part B coverage, before you use a single healthcare service. It went up $17.90 from 2025's $185.00, which is a 9.7% increase — faster than inflation, faster than Social Security COLA. Get used to this pattern. Part B premiums have risen almost every year for the past two decades.

The Part B annual deductible is $283 in 2026. You pay this before Medicare kicks in on Part B services for the year. After the deductible, Medicare covers 80% of approved amounts for most Part B services. You cover the remaining 20% with no cap — which is the exposure Medigap is designed to eliminate.

**Part B Coinsurance and What It Means in Practice**

That 20% with no cap is worth dwelling on. An MRI might cost Medicare $800. Your 20% is $160. Fine. But an outpatient surgery might cost Medicare $15,000. Your 20%? $3,000. Chemotherapy, durable medical equipment, physical therapy that runs for months — these all add up under Original Medicare's 20% coinsurance structure.

For a beneficiary with moderate healthcare use — maybe 4 specialist visits, some lab work, an imaging study or two — annual Part B out-of-pocket costs beyond the premium might run $500-$1,500. For someone managing a serious condition, that same 20% coinsurance can hit $5,000-$8,000 in a year without a supplement.

**When Part B Starts**

If you're drawing Social Security when you turn 65, you're automatically enrolled in Part B. If you're not drawing Social Security, you need to actively sign up during your Initial Enrollment Period — the 7-month window around your 65th birthday. Miss it without a valid reason (like employer coverage) and you pay a 10% late enrollment penalty for every 12 months you delayed. That penalty is permanent. It follows you for life.

IRMAA — Income-Related Monthly Adjustment Amount — is the Medicare surcharge that catches a lot of higher-income retirees completely off guard. It's not a penalty for doing something wrong. It's just what happens when your income exceeds certain thresholds.

Here's the thing that trips people up: IRMAA for 2026 is based on your 2024 tax return. Not what you earned last year. Not what you're earning now. Two years ago. Social Security Administration looks at your MAGI from 2024, and that determines your 2026 Part B and Part D premiums.

This creates situations where someone retires in 2025, dramatically cuts their income, but still pays 2026 IRMAA based on their 2024 W-2 income when they were working full-time. There's a way to fight this — covered in the IRMAA appeals section below — but you need to know it's possible.

**2026 IRMAA Brackets: Part B Surcharges**

These are the thresholds where IRMAA kicks in for Part B, with monthly surcharges added to the $202.90 base premium:

Note: the married filing separately brackets are brutal. CMS essentially treats separate filers as if they had much higher incomes. It's a longstanding quirk that catches people who file separately for unrelated reasons.

**The Real Annual Cost of IRMAA**

Run the numbers on what IRMAA actually costs per year. A single retiree in the second bracket — say, $130,000 in MAGI — pays $81.20 extra per month in Part B surcharges, which is $974.40 extra per year just for Part B. Then add Part D surcharges on top of that. A couple at $300,000 combined MAGI is paying the third bracket: $206.80 × 2 (both spouses) = $413.60/month extra, or nearly $5,000 more per year than the standard premium.

This isn't theoretical. A retired couple with a $1.5 million IRA, pulling $80,000 each in distributions, hits that third bracket and pays $413.60 more per month than their neighbor with identical healthcare use but lower visible income.

**What Counts as MAGI for IRMAA**

Roth conversions done before Medicare eligibility can permanently lower IRMAA exposure. It's one of the most underutilized retirement income planning strategies.

**2026 IRMAA Brackets: Part D Surcharges**

Part D has its own IRMAA surcharge, applied on top of whatever your plan's premium is. Using the same income brackets:

For married filing jointly (thresholds double as shown above), same surcharge amounts apply.

**Appealing IRMAA: Life-Changing Events**

Retirement is the big one. If you retired in 2025, your income dropped dramatically, but SSA is still using your 2024 income to calculate 2026 IRMAA — you can file Form SSA-44 and ask them to use a more recent tax year or a current year estimate.

This is not complicated. It's a one-page form, attach documentation of the income change (pay stub showing last date of employment, for example), submit to your local Social Security office. Approval typically takes 30-90 days. The refund for wrongly paid IRMAA surcharges gets applied as a credit to future premiums. Worth doing every time a major income change occurs.

Part D is its own world of confusion, and honestly the cost structure changed significantly starting 2025 with the Inflation Reduction Act's $2,000 out-of-pocket cap. Here's where things stand in 2026.

**The Base Premium**

The national base beneficiary premium for Part D is $38.99/month in 2026. But almost nobody actually pays exactly $38.99 — that's a calculation baseline used to determine IRMAA surcharges and low-income subsidies. Actual Part D premiums vary by plan and region. They range from roughly $0 (some plans) to $120+ per month depending on your drugs and your geography.

The average Part D premium nationally is around $45-55/month for a decent plan. Shopping matters enormously here. Two plans in the same zip code might have the same base premium but wildly different drug formularies and copay tiers. Run your specific drugs through Medicare's Plan Finder every year during Open Enrollment (October 15 – December 7).

**The Part D Deductible**

The maximum allowable Part D deductible in 2026 is $590. Plans don't have to charge the maximum — many charge less, some charge zero. Generic-only plans sometimes waive the deductible entirely. But if your plan has a deductible, you pay 100% of drug costs until you hit it.

**The $2,100 Out-of-Pocket Cap**

This is the big change. Starting 2025 and continuing in 2026, there is a hard $2,100 annual cap on Part D out-of-pocket spending. Once you've paid $2,100 on covered drugs, your cost for the rest of the year is zero.

Wait — I thought the cap was $2,000? The $2,000 cap applied in 2025. For 2026 it adjusts annually by law based on a formula tied to drug cost trends, landing at $2,100.

This is genuinely transformative for people on expensive brand-name drugs or specialty medications. Before this cap existed, the old coverage gap ('donut hole') meant some patients were paying thousands with no ceiling. A cancer patient on an oral chemotherapy drug costing $8,000/month is now capped at $2,100 regardless of the plan.

**The Coverage Phases (2026)**

Part D technically still has phases even with the cap:

Phase 1 — Deductible Phase: You pay 100% of drug costs until you hit your plan's deductible (up to $590 max).

Phase 2 — Initial Coverage Phase: After the deductible, you pay copays or coinsurance (your plan's cost-sharing structure) until your total out-of-pocket spending hits $2,100.

Phase 3 — Catastrophic Coverage: Once you've paid $2,100 out-of-pocket, you pay $0 for the rest of the calendar year on covered drugs. Period.

The old donut hole that existed between the initial coverage phase and catastrophic coverage has been effectively eliminated. The coverage is now much simpler, though individual plan designs still vary significantly in their copay structures before you hit the cap.

**Part D IRMAA**

Higher earners pay IRMAA surcharges on Part D too (see full table in the IRMAA section above). The surcharge is added on top of your plan's premium and collected by Medicare. So if you're in the second IRMAA bracket and have a $45/month Part D plan, you're actually paying $45 + $14.50 = $59.50/month.

**Medicare Advantage and Drug Coverage**

Most Medicare Advantage plans include prescription drug coverage (MA-PD plans). If you go the MA route, you typically don't need a standalone Part D plan. The drug coverage is bundled into the MA plan, subject to the same $2,100 OOP cap for drugs.

**Formulary Surprises**

Here's something that costs people money every year: they pick a plan in October during Open Enrollment, their insurer adjusts the formulary in January, and suddenly their expensive drug moved from Tier 2 to Tier 4. You're allowed to switch plans during the Annual Enrollment Period each year specifically to avoid this. Set a calendar reminder for October 15 every single year.

Medicare Advantage (Part C) is now the coverage choice for roughly half of all Medicare beneficiaries. And the marketing is genuinely appealing — zero-premium plans, gym memberships, dental and vision bundled in. But the actual cost story is more complicated than those TV commercials suggest.

**Premiums**

The average Medicare Advantage premium in 2026 is approximately $14/month, with around 59% of plans available at $0 premium. That's not a typo. Zero dollars per month for Part C coverage is genuinely possible — and common — in many markets. Private insurers can offer $0 premium MA plans because Medicare pays them a per-member subsidy.

But $0 premium doesn't mean $0 cost. You still pay the $202.90 Part B premium every month regardless of which Medicare path you choose. That Part B premium never goes away.

**The Maximum Out-of-Pocket (MOOP)**

This is the number that matters most in Medicare Advantage. CMS sets the maximum MOOP that MA plans can charge in 2026 at $9,250 for in-network services. But here's what matters more: the median MOOP across all plans is approximately $5,900 in 2026, up from $5,400 in 2025.

That rising MOOP is a trend worth watching. When plans say 'in-network MOOP of $4,500' in their marketing, they mean that's your maximum annual exposure for covered in-network services. Hit that cap and you pay nothing more for covered care for the rest of the year. But you need to stay in-network, which in some regions is genuinely restrictive.

Out-of-network MOOP limits are typically higher — often $14,000-$15,000 for combined in- and out-of-network exposure, and some plans have no out-of-network coverage at all (HMO structures).

**Copays and Coinsurance**

These copay structures can make costs more predictable than Original Medicare — no unlimited 20% exposure — but they add up fast if you're a heavy healthcare user.

**The Hidden Cost: Prior Authorization**

Medicare Advantage plans are legally allowed to require prior authorization for many services, including specialist referrals, certain imaging studies, surgeries, and hospital admissions. CMS has tightened rules on this in recent years, but it still happens. A prior auth denial for a planned surgery means delayed care and potential appeals. That's a cost measured in time and stress, not dollars — but it's real.

**Extra Benefits: Real vs. Marketing**

Many MA plans advertise dental, vision, hearing, and gym memberships. The value varies enormously. A plan might offer '$2,000 in dental benefits' with an annual maximum of $1,500 and a 50% coinsurance on major services. Not exactly what the ad implied. Verify the actual coverage limits before counting these benefits in your cost analysis.

**Who MA Works Best For**

Honestly? People in their 60s and early 70s who are relatively healthy, live in a metro area with broad in-network options, prefer the predictability of copays, and don't mind dealing with a managed care structure. The zero or low premium means less cash out the door monthly.

Who should think twice? People with chronic conditions who see specialists frequently, anyone who travels often and needs out-of-network flexibility, and people with specific specialists or hospitals they won't give up. Original Medicare + Medigap serves these folks better, even at higher monthly cost.

Medigap fills the gaps in Original Medicare — covering the deductibles, coinsurance, and copays that Original Medicare leaves you exposed to. You pay more upfront in premiums for the predictability of near-zero cost when you actually use healthcare.

The standardized plans are lettered A through N (not all letters are available). For most people turning 65 in 2026, the relevant comparison is between Plan G (the most comprehensive plan available to new enrollees), Plan N (a lower-premium option with some cost-sharing), and Plan K or L (high-deductible options).

**Plan G: What It Covers**

What Plan G does NOT cover: the Part B deductible ($283 in 2026). You still pay that yourself. Then everything else is covered.

The practical result: with Plan G, your predictable annual out-of-pocket exposure is $283 (Part B deductible) plus whatever your Part D plan costs. That's essentially it, assuming you stay with doctors who accept Medicare assignment.

**Plan G 2026 Pricing**

This is where things get regional and highly variable. Some real ranges for a 65-year-old enrolling in Plan G in 2026:

For a 65-year-old woman in Nashville: roughly $135/month. Same woman in Miami: $290/month. Same coverage, wildly different price — this is why location matters enormously.

Age matters too, unless you're in a state with community or issue-age rating. Most states use attained-age rating, meaning your premium goes up every year as you age. A 75-year-old on Plan G often pays 30-50% more than a 65-year-old enrolled with the same carrier.

**Plan N: Lower Premium, Some Cost-Sharing**

Plan N typically runs $100-$160/month for a 65-year-old — meaningfully cheaper than Plan G. The catch: you pay up to a $20 copay for office visits and up to $50 for ER visits (waived if admitted). You're also exposed to Part B excess charges — the difference between what a provider charges and what Medicare approves — though fewer than 5% of providers use excess charges these days.

For healthy retirees who rarely see doctors beyond preventive care, Plan N is often the smarter financial choice. Run the math: if you save $600/year on premiums vs. Plan G and average less than $600 in copays, Plan N wins.

**High-Deductible Plan G**

There's a high-deductible version of Plan G with a 2026 deductible of $2,870. After you pay that deductible out-of-pocket, coverage kicks in like regular Plan G. The premium? Often $50-$80/month. For young, healthy 65-year-olds with some financial buffer, this is worth serious consideration — especially as a bridge to standard Plan G later.

**The Open Enrollment Window Is Critical**

When you turn 65 and enroll in Part B, you have a 6-month Medigap Open Enrollment Period. During that window, insurers cannot deny you coverage, charge higher premiums due to pre-existing conditions, or impose waiting periods. Once that window closes, guaranteed issue ends (in most states), and insurers can underwrite you. If you have diabetes, heart disease, COPD, or most other significant health conditions, you might not qualify for Medigap at all after that window.

This isn't theoretical. People who delay Medigap enrollment, develop a health condition, and then try to switch from Medicare Advantage get stuck. Locked into MA with no Medigap option available. The Medigap enrollment window at 65 is one of the most consequential windows in personal finance — and one of the least understood.

**Medigap and Part D**

Medigap covers most Medicare cost-sharing but does not cover prescription drugs. You still need a standalone Part D plan. Budget Plan G + Part D: $140-$220 (Plan G) + $45-$60 (Part D) = roughly $185-$280/month in supplement premiums, in addition to the $202.90 Part B premium.

Total monthly Medicare spend with Plan G at age 65 in a moderate-cost state: $202.90 (Part B) + $160 (Plan G) + $50 (Part D) = $412.90/month = $4,954.80/year just in premiums, before any healthcare use.

Enough individual line items. Here's what the full cost picture looks like for different types of Medicare beneficiaries in 2026. These are real dollar breakdowns.

**Scenario 1: Healthy 65-Year-Old, Below IRMAA Threshold, Medicare Advantage**

Profile: Just retired, income $75,000/year from Social Security + IRA distributions, generally healthy, lives in Phoenix, AZ.

Coverage choice: $0-premium Medicare Advantage HMO with $4,800 MOOP, includes Part D.

This is the best-case realistic scenario. If this person stays healthy, they'll spend under $2,600 a year on Medicare. And that's genuinely possible for healthy early retirees on zero-premium MA plans.

**Scenario 2: Moderate Healthcare User, Original Medicare + Plan G**

Profile: 67-year-old woman, income $85,000/year, manages hypertension and high cholesterol, sees primary care 3x/year and cardiologist 2x/year, takes 3 brand-name drugs.

Coverage: Original Medicare + Plan G + Part D.

Note: This woman has essentially unlimited protection. A hospitalization of any length doesn't cost her a dollar above her Plan G premium. She knows her maximum annual medical exposure is her $283 Part B deductible. The predictability is worth the $6,181 premium cost.

**Scenario 3: Heavy Healthcare User, Medicare Advantage, Hits MOOP**

Profile: 72-year-old man, income $90,000/year, Type 2 diabetes with complications, knee replacement surgery needed, 5 specialists, frequent lab work.

Coverage: Medicare Advantage PPO, $0 premium, $5,900 MOOP, $2,100 drug cap.

This is the scenario where Medicare Advantage's low premium promise falls apart. The zero-premium plan cost this man over $10,000. If he'd had Plan G, that same year of healthcare use would have cost him roughly $6,200 — the premium cost plus his $283 deductible. Plan G is $4,200 cheaper in this heavy-use year.

**Scenario 4: High-Income Retiree, IRMAA Bracket 3**

Profile: 68-year-old couple, filing jointly, combined MAGI of $310,000 (large RMDs from substantial IRAs), both generally healthy, Original Medicare + Plan G.

For the couple: $17,621.20/year in Medicare costs. This is the IRMAA reality. A couple with identical health and identical coverage to a median-income couple pays over $17,600 while that other couple pays around $12,000. The IRMAA premium tax is $5,600+ annually just on the income-based surcharges.

This is why Roth conversions done in your 50s and early 60s matter so much. Lower your MAGI in Medicare years and you capture thousands in IRMAA savings over a 20-30 year retirement.

**Scenario 5: Low-Income Beneficiary, Medicare Savings Program + Extra Help**

Profile: 70-year-old single woman, Social Security $1,100/month ($13,200/year), small savings.

Eligibility: Qualifies for QMB (Qualified Medicare Beneficiary) program.

This is the program that changes everything for people who qualify. Most don't know it exists.

There's a lot of advice out there about cutting Medicare costs that's basically useless — 'shop around during enrollment!' Thanks, obvious. Here's the stuff that actually moves the needle.

**Medicare Savings Programs (MSPs)**

Four programs, run through Medicaid in each state, that help lower-income Medicare beneficiaries pay their premiums and cost-sharing. Over 10 million people qualify but millions don't apply because they don't know these programs exist.

Qualified Medicare Beneficiary (QMB): The best program. Pays your Part A premium (if applicable), Part B premium, and all Medicare cost-sharing — deductibles, copays, coinsurance. Income limit for 2026: $1,350/month individual ($16,200/year), $1,824/month couple ($21,888/year). Resource limits are generous and exclude your home, car, and personal property. Even if you exceed the income limit, apply — state income disregards vary and many people who think they don't qualify actually do.

Specified Low-Income Medicare Beneficiary (SLMB): Pays your Part B premium only. Income limit: $1,616/month individual, $2,184/month couple. The Part B premium savings alone is $2,434.80/year — not nothing.

Qualifying Individual (QI): Pays Part B premium. Income limit: $1,816/month individual, $2,455/month couple. Funded differently than QMB/SLMB — first-come-first-served with a funding cap, so apply early in the year.

Qualified Disabled and Working Individuals (QDWI): Pays Part A premium for working disabled beneficiaries under 65. More narrow application.

To apply: contact your state Medicaid agency or call 1-800-MEDICARE. The application is separate from Medicare enrollment and requires income/resource documentation.

**Extra Help for Part D (Low-Income Subsidy)**

Automatic qualification: If you're enrolled in QMB, SLMB, QI, or Medicaid, you automatically get Extra Help. No separate application needed.

Income limit for LIS applications: roughly $22,000/individual, $30,000/couple (2026 approximate — check SSA.gov for exact figures). Apply through SSA at ssa.gov or call 1-800-772-1213.

This is real money. Full Extra Help can save $4,000-$8,000 a year for someone on multiple expensive medications.

**IRMAA Appeals**

Covered in detail above, but worth repeating: if your income dropped significantly due to retirement, divorce, death of a spouse, or any other qualifying life-changing event, file Form SSA-44 immediately. Don't wait. Every month you pay IRMAA at the wrong bracket is money you can get back.

**State Pharmaceutical Assistance Programs (SPAPs)**

Many states have additional programs that help with drug costs on top of Medicare. PACE in Pennsylvania, EPIC in New York, SHINE in various states. These stack with Medicare and can cover copays or premium costs that federal programs leave uncovered. Check your state's Department of Aging or Health.

**The Medicare Plan Finder Annual Habit**

Every October 15, run every drug you take through Medicare's Plan Finder (medicare.gov/plan-compare). Drug pricing changes every year. The cheapest Part D plan for your specific medications this year might not be next year. Fifteen minutes of shopping can save hundreds. And this really does work — it's not just theoretical.

**Delay Medicare Part B if You Have Employer Coverage**

If you're still working at 65 and covered by a employer group health plan with 20+ employees, you can delay Part B enrollment without penalty. The Part B SEP (Special Enrollment Period) lets you sign up when your employer coverage ends without a late enrollment penalty. This is legitimate and can make financial sense if your employer plan is good — particularly if your employer covers most of the premium.

**The Roth Conversion Strategy**

Not an immediate fix, but the most powerful long-term lever: reduce your future MAGI by doing Roth conversions between retirement and Medicare eligibility, or in years before MAGI-heavy events like large RMD years. Every dollar shifted from traditional to Roth IRA is a dollar that won't count toward IRMAA in Medicare years. At the third IRMAA bracket, each dollar of MAGI reduction saves about $0.10-$0.15 in annual Medicare premiums for a couple. That sounds small. Over 20 years of retirement, strategic Roth conversions can save $30,000-$80,000 in IRMAA surcharges.

This is the decision that probably matters most for new Medicare enrollees. And unlike most healthcare decisions, you can actually model it financially with reasonable accuracy.

**The Core Tradeoff**

Medicare Advantage: Lower monthly premiums, potentially zero. But higher exposure when you use healthcare — copays, coinsurance, and a MOOP that averages $5,900 and can hit $9,250.

Original Medicare + Medigap (Plan G): Higher monthly premiums, lower healthcare use costs. Nearly unlimited protection against catastrophic medical costs once you're past the $283 Part B deductible.

**5-Year Model: Two 65-Year-Old Enrollees in 2026**

Person A chooses a $0-premium MA plan with $5,000 MOOP. Person B chooses Original Medicare + Plan G ($160/month) + Part D ($50/month).

Both pay $202.90/month Part B premium. Assume no IRMAA.

Close. In this moderately unlucky scenario for Person A, Plan G comes out about $2,400 cheaper over 5 years despite the higher premiums.

Person A saves over $11,000. The tradeoff is real.

**The Variable That Changes Everything**

The MA-vs-Medigap math is very sensitive to actual healthcare use. MA wins convincingly in healthy years. Medigap wins in sick years. The problem is you can't know which years are coming.

**The Lock-In Risk**

One underappreciated factor: if you start with MA and develop serious health conditions, you may not be able to switch to Medigap later (in most states). You can always drop Plan G and go to MA. Switching from MA to Plan G requires medical underwriting in most states outside your initial Open Enrollment period. People who start with MA in good health, develop cancer or heart failure, and then want the unlimited coverage of Plan G often can't get it.

So the decision isn't just about current-year math. It's about optionality. Medigap at 65 preserves your ability to change later. MA at 65 may not.

Medicare premiums and costs interact with the tax code in ways most beneficiaries either miss or misunderstand. Here's how it actually works.

**Schedule A Medical Deduction**

If you itemize deductions, Medicare premiums — Part A (if you pay them), Part B, Part D, and Medigap — count as medical expenses on Schedule A. Medical expenses are deductible to the extent they exceed 7.5% of your adjusted gross income.

For most retirees, the standard deduction ($15,000 single, $30,000 married filing jointly in 2026) exceeds their itemized deductions, so they take the standard deduction and get zero benefit from their Medicare premium costs. The 7.5% threshold is hard to hit for people with moderate income and no catastrophic medical events.

Example: $80,000 AGI. Threshold: $6,000. If you paid $5,000 in Medicare premiums and had $2,500 in other medical costs — $7,500 total. That's $1,500 above the threshold, so $1,500 would be deductible if you itemize. But your standard deduction is $15,000, so you only itemize if your total deductions exceed $15,000.

The Schedule A deduction is largely a secondary benefit for high-income itemizers.

**The Self-Employed Deduction: Actually Valuable**

If you're self-employed and earning a net profit, you can deduct 100% of Medicare premiums — Part B, Part D, and Medigap — as a self-employed health insurance deduction on Schedule 1 (Line 17). This is an above-the-line deduction, meaning it reduces your AGI directly without requiring itemization.

This also applies to Medicare premiums for a non-working spouse.

What's included: Part A premiums (if applicable), Part B premiums, Medicare Advantage premiums, Part D premiums, and Medigap premiums.

The constraint: you can't deduct more than your net self-employment income. And you can't use this deduction for months when you (or your spouse) were eligible for employer-sponsored health insurance.

For a self-employed consultant in their 60s paying $5,000-$8,000/year in Medicare premiums, this deduction saves $1,250-$2,800/year in federal taxes depending on their bracket. Real money.

**IRMAA Doesn't Reduce MAGI for IRMAA Purposes**

Paying higher IRMAA premiums doesn't lower the MAGI that determines next year's IRMAA. The premium you pay isn't deductible above-the-line unless you're self-employed. This is a frustrating feature of the system — you can't use your IRMAA payment to reduce your IRMAA.

**HSA Compatibility**

Once you're enrolled in Medicare Part A or Part B, you can no longer contribute to a Health Savings Account (HSA). You can still spend down existing HSA funds on Medicare premiums and out-of-pocket costs. Medicare premiums — including IRMAA surcharges — are qualified HSA expenses. If you have HSA funds from your working years, using them to pay Part B premiums is a tax-advantaged way to fund Medicare.

This is worth planning around. If you're approaching 65 with a large HSA balance, maximize contributions in the year before Medicare enrollment. And coordinate carefully — enrolling in Medicare Part A automatically stops HSA contributions, and Part A enrollment is often automatic if you're claiming Social Security.

Most retirement planning tools use a flat healthcare cost estimate that doesn't match reality at all. Here's a more honest framework.

**The Three Healthcare Buckets**

Bucket 1 — Premiums: The fixed, predictable costs. Part B premium, Part D premium, Medigap or MA premium. These you know. In 2026, for most people without IRMAA, budget $3,500-$5,500/year in premiums (the range from bare-bones MA to Plan G + Part D).

Bucket 2 — Predictable Out-of-Pocket: Copays, drug costs, deductibles for typical healthcare use. For a moderately healthy person, budget $500-$2,000/year. With good drug coverage and Medigap, this skews to $300-$600/year.

Bucket 3 — Catastrophic Reserve: This is the hard one. Medicare — even with Medigap — doesn't cover long-term care. A nursing home averages $8,000-$10,000/month. Assisted living averages $4,500-$5,500/month. Medicare covers short-term skilled nursing care only. After 100 days, you're paying privately.

For Bucket 3, the honest answer is you need either long-term care insurance, a Medicaid strategy if you're at lower income, or a self-insurance reserve of $200,000-$400,000 earmarked for potential long-term care costs. This isn't part of Medicare cost — it's adjacent to it — but any realistic healthcare budget for retirement has to account for it.

**Annual Premium Increases**

Budget for Medicare costs to rise 5-8% annually on average. Part B premium increased 9.7% from 2025 to 2026. Medigap premiums in attained-age-rated states typically increase 4-8% annually plus age-based increases. Over a 20-year retirement, your Medicare costs will likely double in real terms.

If you're 65 and paying $5,000/year in Medicare premiums, by 85 you might be paying $12,000-$15,000/year — before healthcare use costs.

**Building the Retirement Budget Line**

A realistic healthcare budget for retirement, by income tier:

Income under $25,000 (potentially MSP/Extra Help eligible): Target budget: $0-$600/year if qualified for QMB. Apply immediately.

Income $50,000-$100,000, generally healthy, Medicare Advantage: Year 1-5 budget: $3,000-$4,500/year total Year 6-15 budget: $4,000-$7,000/year (increasing premiums + more healthcare use)

Income $50,000-$100,000, Original Medicare + Plan G: Year 1-5 budget: $5,000-$7,000/year Year 6-15 budget: $7,000-$10,000/year

Income above $130,000 single (IRMAA impact): Add $1,000-$6,000/year in IRMAA surcharges to the above figures, depending on bracket.

**Fidelity's Healthcare Cost Estimate**

Fidelity Investments' 2025 estimate: a couple retiring at 65 will need approximately $330,000 (after-tax) to cover healthcare costs in retirement. That's roughly $165,000 per person. That's the savings target for healthcare alone, separate from living expenses. It covers premiums and out-of-pocket costs but not long-term care.

The number feels enormous. But spread over 20-25 years of retirement, it's about $13,000-$16,500/year per couple — which aligns with the real-world budgets above.
