Quick answer: In 2026, most people pay $0 for Part A, a standard Part B premium of $202.90/month (with a $283 annual deductible), and a Part D plan whose covered-drug costs are capped at $2,100 out-of-pocket for the year. Your total cost depends on whether you add a Medigap plan (higher premium, fewer surprises) or choose Medicare Advantage (lower premium, copays up to an annual out-of-pocket maximum). Higher-income enrollees also pay IRMAA surcharges on Part B and Part D.

Breaking Down Medicare Costs Into Components

One of the biggest misconceptions about Medicare is that it's "free" once you turn 65. While Medicare Part A is premium-free for most beneficiaries who paid Medicare taxes for at least 10 years, Medicare does have costs. Understanding these costs is essential for budgeting your healthcare expenses in retirement and making informed decisions about coverage options.

Medicare costs come in several forms: monthly premiums, annual deductibles, copayments, coinsurance, and out-of-pocket maximums. The combination of these costs varies dramatically depending on which Medicare plan you choose. This article breaks down each component so you can understand what you'll actually pay for your healthcare in 2026.

Medicare Part A Costs

The Part A Premium

Most people age 65 and older don't pay a monthly Part A premium because they or their spouse paid Medicare taxes for at least 40 quarters (10 years) while working. However, some beneficiaries do pay a Part A premium if they don't meet the work history requirement. In 2026, people who paid Medicare taxes for fewer than 30 quarters pay $565 per month, and people who paid for 30 to 39 quarters pay $311 per month.

If you've worked long enough in the United States, you won't pay a Part A premium, making Part A essentially free coverage for hospital and skilled nursing facility care.

Part A Deductible

While you may not pay a monthly premium for Part A, you will face a deductible for hospital stays. The Part A deductible in 2026 is $1,736 per benefit period (up from $1,676 in 2025). A benefit period begins when you're admitted to the hospital and ends 60 days after you're discharged. If you're readmitted more than 60 days after discharge, a new benefit period begins and a new deductible applies.

This deductible covers all hospital services for days 1-60. After day 60 in a hospital, you pay coinsurance of $434 per day for days 61-90 in 2026. After day 90 you pay $868 per day for each of your 60 lifetime reserve days. These are significant potential costs, which is why supplemental coverage is important.

Skilled Nursing Facility Costs

If you need skilled nursing care after a hospital stay, Part A covers up to 100 days per benefit period. You pay $0 for days 1-20, then $217.00 per day for days 21-100. These daily copayments can add up quickly for extended stays.

Medicare Part B Costs

The Part B Premium

Unlike Part A, all beneficiaries pay a monthly Part B premium. In 2026, the standard Part B premium is $202.90 per month ($2,434.80 annually) for beneficiaries with income below specific thresholds. However, if your income exceeds those thresholds, you pay income-related monthly adjustment amounts (IRMAA) on top of the standard premium.

IRMAA applies once your Modified Adjusted Gross Income (MAGI) exceeds $109,000 (single) or $218,000 (married filing jointly), and it affects both Part B and Part D. In 2026, the first IRMAA tier raises the Part B premium from the standard $202.90 to $284.10 per month, and the brackets climb to $689.90 per month at the highest income tier ($500,000+ single / $750,000+ married). At the same income tiers, you also pay an extra $14.50 to $91.00 per month on top of your Part D plan premium. IRMAA is based on your MAGI from two years prior, so your 2024 tax return determines your 2026 surcharge.

If you receive Social Security benefits, your Part B premium is deducted from your monthly payment. If you don't, Medicare sends you a bill.

Part B Deductible

Part B has an annual deductible of $283 in 2026. Once you meet this deductible, Part B typically covers 80% of approved services, and you're responsible for 20% coinsurance. However, these costs vary significantly depending on the specific service and whether the provider accepts Medicare assignment.

Part B Coinsurance

For most doctor visits and outpatient services, you pay 20% coinsurance after meeting the annual deductible. If your doctor doesn't accept Medicare assignment, you could pay even more. This coinsurance has no annual limit under Original Medicare, so your out-of-pocket costs can accumulate throughout the year depending on how many doctor visits and services you use.

Medicare Part D Drug Costs

Part D Premiums

Part D premiums vary widely depending on the plan you choose, from as low as $5-10 per month to $100+ per month. The average premium in 2026 is approximately $35-45 per month for a basic plan. Standalone Part D plans are available for those with Original Medicare, while Medicare Advantage plans typically include drug coverage as part of the overall plan premium.

Your Part D premium is due whether you use medications or not. If you go 63 days or more in a row without Part D or other creditable drug coverage after you are first eligible, you pay an extra 1% of the national base beneficiary premium ($38.99 in 2026) for each full month you went without coverage. The penalty is added to your Part D premium for as long as you have Part D.

Part D Deductible

Part D plans may have an annual deductible. In 2026 no plan's deductible can be more than $615. Some plans have no deductible, while others charge the maximum. Before the deductible is met, you pay the full cost of most medications. One exception worth knowing: the shingles vaccine is covered at $0 under Part D, along with other CDC-recommended adult vaccines, even before you meet the deductible.

Part D Out-of-Pocket Limits

Your out-of-pocket drug costs are capped at $2,100 per year in 2026 (up from $2,000 in 2025). Once you've paid $2,100 out-of-pocket for covered medications, Medicare covers 100% of your remaining covered drug costs for the rest of that year. This annual limit provides predictability and protection against catastrophic drug costs.

Medicare Advantage vs. Original Medicare Costs Compared

Cost Component Original Medicare + Medigap Medicare Advantage
Part A Premium $0 (for most) $0 (included)
Part B Premium ~$203/month ~$203/month
Medigap/Advantage Premium $150-$300+/month $0-$200/month
Part D Premium $35-$50/month Included in plan
Annual Deductible $283 (Part B) $0-$500
Doctor Visit Copay 20% coinsurance $15-$50
Hospital Stay Deductible $1,736 (per benefit period) $0-$500
Annual Out-of-Pocket Maximum Unlimited (unless Medigap) Set by the plan; no more than $9,250 in-network in 2026
Total Annual Cost Range $4,500-$8,000+ $2,500-$5,000+

Medigap Supplement Plan Costs

Premium Variation by Plan Type

Medigap plans are standardized by the federal government, so all companies offering Plan G provide identical benefits. However, premiums vary dramatically based on the insurance company, your age, your location, and the insurance company's rating method.

The most popular Medigap plans are Plan G and Plan N. Plan G has higher premiums (typically $180-$300+ per month) but more comprehensive coverage. Plan N has lower premiums (typically $120-$200+ per month) but slightly higher out-of-pocket costs for doctor visits and emergency room care. Both plans significantly reduce your out-of-pocket costs compared to Original Medicare alone.

Age-Related Premium Increases

Medigap premiums often increase with age, depending on how the insurer rates the policy. Insurance companies use one of three rating methods: community-rated (same price regardless of age), issue-age-rated (price based on age when you buy the plan), or attained-age-rated (price increases as you age). Understanding which rating method an insurance company uses helps you estimate your long-term costs.

Real-World Annual Cost Scenarios

Scenario 1: Healthy Beneficiary with Minimal Healthcare

Margaret, age 66, no chronic conditions, takes no medications

With Original Medicare: Part A premium $0, Part B premium $2,435 (≈$202.90/month in 2026), Part B deductible $283, average doctor visit (1 per year) $20, stand-alone Part D premium $450. Total annual cost: approximately $3,188.

With Medicare Advantage (zero premium): Part B premium $2,435, plan premium $0, doctor visit copay $15. Total annual cost: approximately $2,450.

With Medigap Plan G: Part B premium $2,435, Plan G premium $2,400, Part D premium $450, Part B deductible $283 (Plan G does not cover it). Total annual cost: approximately $5,568.

Lowest projected annual cost in this scenario: Medicare Advantage (about $2,450). The trade-off is that Medicare Advantage plans use provider networks and set their own copays, while Original Medicare with Medigap costs more up front but offers broader provider flexibility. The right fit depends on Margaret's doctors, prescriptions, and travel plans, not on cost alone.

Scenario 2: Beneficiary with Multiple Chronic Conditions

Robert, age 72, diabetes, heart disease, arthritis, takes 5 medications, sees doctors monthly

With Original Medicare: Part A premium $0, Part B premium $2,435 (≈$202.90/month in 2026), Part B deductible $283, average monthly doctor visits (12 @ 20% coinsurance) $1,200, specialist copayments $500, hospital stay $1,736 deductible, stand-alone Part D premium $450. Total annual cost: approximately $6,604.

With Medicare Advantage: Part B premium $2,435, plan premium $100, monthly doctor visit copays $600, specialist copays $400, hospital stay deductible $300, Part D included. Total annual cost: approximately $3,835.

With Medigap Plan G: Part B premium $2,435, Plan G premium $2,880, Part D premium $450, Part B deductible $283, other doctor visits and the hospital stay covered. Total annual cost: approximately $6,048.

Lowest projected annual cost in this scenario: Medicare Advantage (about $3,835). Robert uses a lot of care, so the plan's copays add up, but its annual out-of-pocket maximum caps what he can pay in a bad year, which is the protection Original Medicare alone does not offer; Medigap Plan G (about $6,048) provides similar protection with broader provider flexibility at a higher fixed premium. The right fit depends on whether his doctors and medications are covered and on how much he travels, not on cost alone.

Scenario 3: High-Utilization Beneficiary

Sandra, age 75, multiple conditions, sees doctors 2-3 times monthly, takes 7 medications, had hospital stay

With Original Medicare: Part A premium $0, Part B premium $2,435 (≈$202.90/month in 2026), Part B deductible $283, monthly doctor visits (24 @ 20% coinsurance) $2,400, specialist copays $800, hospital stay $1,736 deductible, stand-alone Part D premium $500. Total annual cost: approximately $8,154.

With Medicare Advantage: Part B premium $2,435, plan premium $150, monthly doctor visit copays $1,200, specialist copays $600, hospital stay deductible $500, Part D included. Total annual cost: approximately $4,885.

With Medigap Plan G: Part B premium $2,435, Plan G premium $3,200, Part D premium $500, Part B deductible $283, other doctor visits and the hospital stay covered. Total annual cost: approximately $6,418.

Lowest projected annual cost in this scenario: Medicare Advantage (about $4,885), because the plan's annual out-of-pocket maximum (no more than $9,250 for in-network care in 2026, and lower in many plans) limits what she can pay for covered medical services, which Original Medicare alone does not do. The trade-off is network restrictions versus the provider flexibility of Medigap Plan G (about $6,418). The right fit depends on Sandra's doctors, drugs, and travel, not on cost alone.

Important: These scenarios use 2026 estimated costs. Actual costs vary by location, specific plan, income level (for IRMAA), and individual healthcare usage. Work with a Medicare broker to calculate your specific costs based on your actual health situation and medications. What you pay at the pharmacy is left out of all three options, because the $2,100 Part D cap applies under any Part D coverage and the amount depends on your prescriptions and plan. The plan premiums and copays shown are round illustrative numbers, not quotes from any plan.

Hidden Costs You Should Know About

Income-Related Monthly Adjustment Amounts (IRMAA)

If your income exceeds specific thresholds, you'll pay additional amounts (IRMAA surcharges) on top of your Part B premium and your Part D premium, including the drug coverage in a Medicare Advantage plan. These surcharges are based on your Modified Adjusted Gross Income (MAGI) from two years prior. In 2026, beneficiaries with MAGI over $109,000 (single) or $218,000 (married filing jointly) face IRMAA surcharges — adding roughly $81 to $487 per month to the Part B premium depending on income, plus $14.50 to $91.00 per month on Part D.

Excess Charges in Original Medicare

If you have Original Medicare and see a doctor who doesn't accept Medicare assignment (a provider who accepts Medicare patients but doesn't agree to the Medicare fee schedule), that doctor can charge you up to 15% more than the amount Medicare allows for that service. These excess charges aren't covered by Medicare and can accumulate. This is another reason why Medigap's Plan G is popular—it covers excess charges.

Part D Coverage Gap (Donut Hole): Ended in 2025

The coverage gap (often called the donut hole) ended in 2025. In 2026 you pay the plan's deductible if it has one, then your copays or coinsurance until your out-of-pocket spending on covered drugs reaches $2,100, and nothing for covered drugs after that. You should still understand how drug formularies work. Not all medications are covered at the same tier. A medication on a higher tier costs more in copayments, and some medications may not be covered at all, requiring you to pay full price or switch medications.

Planning Your Medicare Budget

Calculate Your Baseline Costs

Start by calculating what you'll definitely pay: Part B premium (~$203/month), and any supplemental plan premium. This baseline is likely to be $2,500-$4,000 annually depending on your choices.

Estimate Usage-Based Costs

Think about your current healthcare usage. How many doctor visits do you have yearly? How many specialist visits? This helps you estimate variable costs under different plans. Working with a broker to run cost estimates based on your actual medications and doctors is invaluable.

Consider Worst-Case Scenarios

What if you're hospitalized? What if you need emergency surgery? Having catastrophic cost protection through either Medicare Advantage's out-of-pocket maximum or Medigap's comprehensive coverage is essential. Don't choose a plan solely based on best-case scenarios.

Review Annually

Medicare costs change every year. If you have a Medicare Advantage or Part D plan, your plan's Annual Notice of Change (ANOC), which arrives each fall, shows next year's premium, deductible, and copays side by side with this year's. Our guide to what to check in your Medicare ANOC walks through it line by line. During Annual Enrollment (October 15 – December 7), review your current plan and compare it to alternatives. Changes in your health status, medications, or doctors may make a different plan a better fit for the coming year.

Key Takeaways

Understanding Medicare costs is complex, but it's essential for making informed decisions about your healthcare coverage. The right plan for you depends on your specific health situation, medications, doctors, and budget. Don't make these decisions in isolation—consult with a Medicare broker who can analyze your actual situation and help you compare which plan fits your needs and budget.

Frequently asked questions about Medicare costs

How much does Medicare cost per month for most people?
Most people pay $0 per month for Part A and the standard Part B premium of $202.90 per month in 2026. On top of that, a standalone Part D drug plan averages roughly $35 to $45 per month for a basic plan, a Medigap policy typically runs $120 to $300 or more depending on the plan letter, and many Medicare Advantage plans charge $0 beyond the Part B premium. Higher-income enrollees also pay IRMAA surcharges.
Is Medicare free at 65?
No. Part A is premium-free at 65 for most people who paid Medicare taxes for at least 10 years, but Part B costs $202.90 per month in 2026, and you still face deductibles ($1,736 per benefit period for a hospital stay under Part A and $283 per year under Part B), 20% coinsurance on most Part B services, and prescription drug costs unless a plan covers them.
How much does Medicare Part A cost?
Part A has no monthly premium for most people. If you paid Medicare taxes for fewer than 40 quarters, the 2026 premium is $311 per month (30 to 39 quarters) or $565 per month (fewer than 30 quarters). Everyone pays the Part A deductible of $1,736 per benefit period for a hospital stay, plus daily coinsurance after day 60, and $217 per day for days 21 through 100 in a skilled nursing facility.
What is the average cost of Medicare per month?
There is no single average because it depends on the coverage you add. A useful baseline for 2026 is the $202.90 Part B premium plus a Part D premium of roughly $35 to $45, or about $240 to $250 per month before any care. Adding a Medigap policy brings the typical total to roughly $360 to $500 or more per month, while a $0-premium Medicare Advantage plan keeps the fixed monthly cost near $203 in exchange for copays when you use care.
What is the most you can pay out of pocket with Medicare?
Original Medicare has no annual out-of-pocket maximum, which is the main reason people add a Medigap policy. Medicare Advantage plans set an annual out-of-pocket maximum for covered medical services. For 2026 it cannot be more than $9,250 for in-network care, and many plans set it lower. After you reach it, the plan pays 100% of covered medical services for the rest of the year. Separately, Part D covered-drug costs are capped at $2,100 out of pocket in 2026 under any Part D plan or Medicare Advantage plan with drug coverage.
How much will Medicare cost in 2027?
The 2027 Part B premium and deductible have not been announced yet; CMS usually publishes them in October or November. CMS projects the average Medicare Advantage premium at $12.00 a month and the average stand-alone Part D premium at about $36 a month for 2027. Your own costs depend on the coverage you choose.
