Medicare Costs at 65, 67, and Beyond

How Much Does Medicare Cost Per Month in 2026? Parts A, B, D, Medigap, and IRMAA

Most retirees pay more than the basic Part B premium once drug coverage, supplemental coverage, and possible income-related surcharges are included.

Medicare costs can change a lot depending on the age you enroll, your income, prescriptions, and the coverage you choose. Use our Medicare Cost Calculator to estimate your personal Medicare expenses based on income, coverage choices, and expected healthcare usage. If you want to fit those estimates into a bigger plan, pair them with a monthly budget template and a retirement budget calculator.

2026 Medicare costs at a glance

• Part A premium: $0 for most people; up to $565/month if you do not qualify for premium-free Part A
• Part A hospital deductible: $1,736 per benefit period
• Part B premium: $202.90/month standard premium
• Part B deductible: $283/year
• Part D premium: varies by plan; income-related surcharges can apply
• Medigap: often $100-$300+/month, depending on plan, age, state, and insurer

The fastest way to estimate your own number is to enter your income, drug coverage, and supplement choice in the Medicare Cost Calculator.

What Does Medicare Actually Cover?

Medicare is not one flat monthly bill. Your cost depends on which pieces you use and whether you add private coverage on top of Original Medicare.

For most retirees, the real question is not “What is the Medicare premium?” It is: What will I pay in premiums, deductibles, prescriptions, and possible out-of-pocket exposure over a full year?

Part A is premium-free for most Americans who worked at least 10 years. If you have fewer than 30 work quarters, the full Part A premium can be up to $565/month in 2026. So if you are asking how much Medicare costs at age 65, the answer starts with whether you get premium-free Part A and whether you add Part D, Medigap, or Medicare Advantage.

Part B: The Biggest Line Item

The standard Part B premium in 2026 is $202.90 per month ($2,434.80/year), and the Part B deductible is $283/year. Higher earners pay more through IRMAA.

IRMAA Surcharges (Income-Related Monthly Adjustment Amount)

Medicare generally looks at your income from two years prior, so 2024 income determines your 2026 premium. If your Modified Adjusted Gross Income (MAGI) exceeds certain thresholds, you pay more for Part B and a separate surcharge for Part D:

This means a couple earning $300,000 annually could pay $811.40/month just for Part B, before factoring in Part D premiums, Part D IRMAA, Medigap, or Medicare Advantage costs.

How to Estimate Your Monthly Medicare Cost

Use this simple worksheet before you compare plans:

Then multiply the monthly total by 12 and add any annual deductibles or expected out-of-pocket costs.

That is exactly where a calculator helps: use the Medicare Cost Calculator for premiums and income surcharges, then use the Out-of-Pocket Cost Calculator to stress-test a year with higher medical use.

Part D: Prescription Drug Coverage

Part D plans are sold by private insurers but regulated by Medicare. Premiums, formularies, deductibles, copays, and preferred pharmacies can vary widely by plan and location.

If you take regular prescriptions, compare plans annually during Open Enrollment (October 15 to December 7). A low-premium plan can become expensive if your medications move to a different tier or are not covered well.

Medigap: Plugging the Gaps

Original Medicare (Parts A + B) still leaves meaningful out-of-pocket exposure, including the Part A hospital deductible of $1,736 per benefit period in 2026 and 20% coinsurance on outpatient care with no annual cap.

Medigap (Medicare Supplement) policies help pay those Original Medicare cost-sharing amounts. The tradeoff is higher monthly premiums.

Original Medicare + Medigap vs Medicare Advantage: Compare Total Cost, Not Just Premium

Medicare Advantage can look cheaper because many plans advertise a low or $0 additional premium. That does not automatically mean it is the lowest-cost choice for your situation.

The clean way to compare them is annual total cost:

Annual premiums + expected prescriptions + expected copays/coinsurance + likely uncovered care + worst-case out-of-pocket exposure.

Run the side-by-side math in the Health Plan Comparison Calculator. If one option has a lower premium but much higher risk in a bad health year, the cheaper-looking plan may not be cheaper for you. For more context, read our health plan comparison guide.

Real Example: What a 66-Year-Old Couple Pays for Medicare in 2026

Maria and John are both 66, retired in North Carolina, with combined MAGI of $90,000 (below the IRMAA threshold).

That is more than $11,000/year before any dental, vision, hearing, or uncovered care costs. For people searching what is the average Medicare cost for a retired couple, this is why the answer is often much higher than the basic Part B premium alone.

Example: Higher-Income Retiree With IRMAA

Sandra is 67, single, and has 2024 MAGI of $185,000 from retirement withdrawals and capital gains. In 2026, she pays:

IRMAA can create a sharp monthly jump even before healthcare usage changes. If you are within a few thousand dollars of a threshold, model both sides of the line. A Roth conversion, capital gain, or large retirement account withdrawal can change Medicare premiums two years later.

Four Common Medicare Cost Scenarios

These examples show why “average Medicare cost” is a weak planning number. Your real cost depends on income, prescriptions, supplement choice, and health usage.

What Medicare Does Not Cover

Original Medicare does not fully cover routine dental, most vision care, hearing aids, or long-term care. It also leaves retirees exposed to meaningful out-of-pocket exposure if they stay with Original Medicare and do not buy Medigap or choose a Medicare Advantage plan with stronger protections.

What Can Change Your Medicare Cost the Most?

The biggest cost drivers are your income level for IRMAA, the prescriptions you take, how Medigap is priced in your age band or state, and whether you choose Medicare Advantage or Original Medicare with supplemental coverage. Those choices matter much more than the headline Part B premium most people see first.

How to Lower Your Medicare Costs Without Guessing

1. Plan before you retire. IRMAA is based on income from two years prior. A Roth conversion, capital gain, or large withdrawal can trigger IRMAA costs later. Work with a financial planner to manage MAGI strategically.

2. Use HSA savings carefully after 65. You cannot contribute to an HSA once you are enrolled in Medicare, but existing HSA funds can still be useful for qualified medical expenses. IRS rules generally allow HSA funds to pay Medicare premiums such as Parts B and D after age 65, but not Medigap premiums. Use the HSA Calculator before 65 to estimate how much tax-free medical savings you may have available in retirement, and read the HSA savings guide for the full strategy.

3. Appeal IRMAA if your income dropped. Lost a job, retired, divorced, or lost a spouse? File Form SSA-44 to report a life-changing event and request a lower premium tier for the current year.

4. Compare Part D plans every year. Your plan's formulary changes annually. Switching during Open Enrollment can save hundreds if your prescriptions changed or your plan changed its pricing.

5. Consider out-of-pocket risk. Use the Out-of-Pocket Cost Calculator to decide whether Medigap makes sense versus self-insuring more of the gap.

Medicare Cost Mistakes That Create Surprise Bills

Only budgeting for Part B. Part B is the starting point, not the full bill. Most retirees also need to budget for drug coverage, supplement or Advantage plan costs, and uncovered services.

Ignoring drug formularies. A cheap Part D plan can become expensive if your medications are not covered well. Re-check your prescriptions every Open Enrollment.

Comparing premiums without out-of-pocket risk. A low-premium Medicare Advantage plan may still expose you to higher costs if you need frequent care. Compare expected cost and worst-case cost.

Missing the IRMAA lookback. Medicare uses income from two years prior. A one-time income spike can raise premiums later.

Assuming dental, vision, hearing, or long-term care are fully covered. Original Medicare does not fully cover these categories, so include them separately in your retirement healthcare budget.

When to Enroll

• Initial Enrollment Period: 7 months around your 65th birthday (3 months before, month of, 3 months after)
• Late enrollment penalty: 10% added to Part B premium for every 12 months you delay if you do not have qualifying coverage
• Special Enrollment Period: Available if you had employer coverage at 65; you can enroll without penalty within 8 months of losing that coverage

Missing your Initial Enrollment Period without qualifying coverage is one of the most expensive Medicare mistakes. Set a reminder 4 months before your 65th birthday.

Frequently Asked Questions

How much does Medicare cost per month in 2026? The standard Part B premium is $202.90/month in 2026, with a $283 annual deductible. Your total monthly cost can be higher once Part D, Medigap, Medicare Advantage premiums, prescriptions, and IRMAA are included.

Is Medicare Part A really free? Part A has no monthly premium for most people because they paid Medicare taxes for at least 40 quarters. If you do not qualify for premium-free Part A, you may pay a monthly premium. Part A can still have deductibles and coinsurance when you use hospital or skilled nursing facility care.

What is IRMAA and how does it affect Medicare premiums? IRMAA (Income-Related Monthly Adjustment Amount) is a surcharge added to Part B and Part D for people above Medicare income thresholds. It is based on income from two years prior, so planning ahead is essential.

Does Medicare Advantage cost less than Medigap? Sometimes, but not always. Medicare Advantage may have a lower monthly premium, while Medigap usually has a higher premium but more predictable cost-sharing with Original Medicare. Compare annual premiums, provider network, prescriptions, copays, and worst-case out-of-pocket exposure before choosing.

Does Medicare cover dental, vision, and hearing? Original Medicare generally does not fully cover routine dental care, most vision care, hearing aids, or long-term care. Some Medicare Advantage plans include extra benefits, but details vary by plan and location.

Can HSA funds pay Medigap premiums? Generally no. IRS Pub. 969 allows HSA funds to pay certain Medicare and other health coverage premiums after age 65, but specifically excludes Medicare supplemental policies such as Medigap. HSA funds may still be useful for Parts B and D premiums and qualified out-of-pocket medical expenses.

Why does Medicare use income from two years ago? IRMAA is based on the most recent tax return information available to Social Security, which usually means your MAGI from two years prior. If your income dropped because of a life-changing event such as retirement, divorce, or death of a spouse, you may be able to request a new determination using Form SSA-44.
