What Does Medicare Cost? Premiums, Deductibles, and Out-of-Pocket Expenses Explained

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, those who paid Medicare taxes for fewer than 30 quarters pay approximately $278 per month, while those who paid for 30-39 quarters pay approximately $163 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 approximately $1,676 per benefit period. 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're responsible for daily coinsurance of approximately $419 per day for days 61-90. Beyond day 90, costs are even higher. 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 approximately $209.50 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 approximately $175.90 per month ($2,110.80 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 surcharges range from $35 to $245 per month depending on your Modified Adjusted Gross Income (MAGI). Someone with a MAGI of $194,000 to $243,000 (or $291,000 to $365,000 for married filing jointly) pays approximately $211 per month instead of $176. Those with income above $243,000 ($365,000 married) can pay as much as $420 per month.

Your Part B premium is automatically deducted from your Social Security check each month unless you choose direct payment to Medicare.

Part B Deductible

Part B has an annual deductible of approximately $240 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 delay enrolling in Part D and don't have other creditable coverage, you'll face a permanent late enrollment penalty of approximately 1% of the national average Part D premium for each month you were without coverage.

Part D Deductible

Part D plans may have an annual deductible, which typically ranges from $0 to $600 in 2026. Some plans have no deductible, while others have the maximum deductible. Before the deductible is met, you pay the full cost of most medications.

Part D Out-of-Pocket Limits

Your out-of-pocket drug costs are now capped at $2,000 per year in 2026. Once you've paid $2,000 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

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 increase with age. 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 $2,110, Part B deductible $240, average doctor visit (1 per year) $20, Part D premium $0 (no drug coverage). Total annual cost: approximately $2,370.

With Medicare Advantage (zero premium): Part B premium $2,110, plan premium $0, doctor visit copay $15. Total annual cost: approximately $2,125.

With Medigap Plan G: Part B premium $2,110, Plan G premium $2,400, Part D premium $450, doctor visit covered. Total annual cost: approximately $4,960.

Best choice for Margaret: Medicare Advantage because her healthcare usage is minimal and she doesn't need extra coverage.

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 $2,110, Part B deductible $240, average monthly doctor visits (12 @ 20% coinsurance) $1,200, specialist copayments $500, hospital stay $1,676 deductible, Part D costs $2,000 (capped). Total annual cost: approximately $7,726.

With Medicare Advantage: Part B premium $2,110, plan premium $100, monthly doctor visit copays $600, specialist copays $400, hospital stay deductible $300, Part D included. Total annual cost: approximately $3,510.

With Medigap Plan G: Part B premium $2,110, Plan G premium $2,880, Part D premium $450, doctor visits covered, hospital stay covered. Total annual cost: approximately $5,440.

Best choice for Robert: Medicare Advantage despite higher per-visit costs, his usage is low enough that the plan maximum saves him money compared to Original Medicare, though Medigap would be second choice.

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 $2,110, Part B deductible $240, monthly doctor visits (24 @ 20% coinsurance) $2,400, specialist copays $800, hospital stay $1,676 deductible, Part D costs $2,000. Total annual cost: approximately $9,226.

With Medicare Advantage: Part B premium $2,110, plan premium $150, monthly doctor visit copays $1,200, specialist copays $600, hospital stay deductible $500, Part D included. Total annual cost: approximately $4,560.

With Medigap Plan G: Part B premium $2,110, Plan G premium $3,200, Part D premium $500, doctor visits covered, hospital stay covered. Total annual cost: approximately $5,810.

Best choice for Sandra: Medicare Advantage because even with high utilization, the capped out-of-pocket maximum ($6,700-$7,500) limits her total costs significantly below Original Medicare.

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 regular Part B and Part D premiums, and on Medicare Advantage premiums if applicable. These surcharges are based on your Modified Adjusted Gross Income (MAGI) from two years prior. In 2026, beneficiaries with MAGI over $194,000 (or $291,000 if married filing jointly) face IRMAA surcharges that can add $100-$250 per month to their Medicare costs.

Excess Charges in Original Medicare

If you have Original Medicare and see a doctor who doesn't accept Medicare assignment (about accepts Medicare but doesn't agree to the Medicare fee schedule), that doctor can charge you up to 15% more than the Medicare-approved amount. 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) — Now Minimal

While the coverage gap is largely eliminated in 2026 due to the $2,000 out-of-pocket cap, 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 (~$176/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. During Open 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 optimal for the coming year.
