How Much Does Medicare Cost at Age 65?

A straight answer on what Medicare actually costs at 65, including Part A, Part B, Part D, and what most people end up paying once you add a Medigap or Advantage plan.

Short answer: most people pay around $203 a month just for Part B, plus whatever you pick for drug coverage and a supplement or Advantage plan on top of that. The federal government sets some of these numbers. Your choices set the rest.
Here's the actual breakdown, using the confirmed 2026 figures.

Part A: Usually Free, But Not Nothing

If you or your spouse worked and paid Medicare taxes for at least 10 years (40 quarters), Part A costs you nothing in premium. That covers about 99% of people turning 65.

The catch is the deductible. If you're admitted to a hospital in 2026, you pay $1,736 before Medicare starts covering the stay. That's not a monthly number. It's per benefit period, meaning it can hit more than once a year if you're hospitalized twice with enough time between stays.

Stay past 60 days and you're also on the hook for $434 a day from day 61 through 90.

Part B: The Premium You Can't Avoid

Part B is the one that shows up on your Social Security statement every month. In 2026, the standard premium is $202.90. The annual deductible is $283, after which Medicare picks up 80% of most outpatient costs and you cover the remaining 20%.

That 20% has no cap under Original Medicare. That's the detail most people don't hear until it matters.

If You Make More, You Pay More

This is IRMAA (Income-Related Monthly Adjustment Amount), and it catches people off guard almost every year. It's based on your tax return from two years earlier, so your 2026 premium is set by what you reported in 2024.

• Under $109,000 (single) or $218,000 (joint): you pay the standard $202.90
• Above that, in five tiers: your Part B premium climbs as high as $689.90 a month

If you had a high-income year two years ago from a Roth conversion, a home sale, or a big capital gain, this is worth checking before you assume you'll pay the standard rate.

How to Appeal IRMAA

Part D: Drug Coverage, and a New Cap Worth Knowing

Average Part D premium in 2026 runs about $34.50 a month, though it varies by plan and by which drugs you take. The maximum deductible any plan can charge is $615.

The bigger change: once you've spent $2,100 out of pocket on covered drugs in 2026, your plan pays 100% of the cost for the rest of the year. The old "donut hole" is gone. If you take one or two expensive maintenance medications, this cap is the number that matters most, not the premium.

Part D has its own IRMAA too, separate from Part B's, ranging from $14.50 to $91 a month at the higher income tiers.

The Part Nobody Skips: Medigap or Medicare Advantage

Parts A and B together are called Original Medicare, and on their own they leave that 20% coinsurance wide open with no yearly limit. Almost nobody stops there. You'll add one of two things:

A Medigap (Medicare Supplement) policy. This picks up some or all of that 20%, plus the Part A deductible depending on the plan. Premiums vary by state, county, and insurer, and in most states they're also priced by your age, meaning they go up as you get older. In Minnesota, you get a one-time guaranteed issue window during your Medigap Open Enrollment Period where insurers can't turn you down or charge you more for health conditions. Miss that window and underwriting can change your options.

A Medicare Advantage plan. These often carry a $0 premium (you still pay your Part B premium) and bundle in drug coverage, but they work through a network and use copays instead of the 20% coinsurance. Your yearly out-of-pocket maximum here is capped by law, which is the trade-off for the network restriction.

Neither option has one universal price. This is the part that actually needs a conversation, not a chart.

Putting It Together

For someone with average income and no major health issues, a realistic monthly range at 65 looks like this:

Piece Typical 2026 Cost
Part B premium $202.90
Part D premium ~$34.50 (varies by plan)
Medigap or Advantage premium $0 to $200+ (varies widely)Add it up and most people land somewhere between $200 and $450 a month before counting any copays, coinsurance, or the deductibles above. Higher income changes the Part B and Part D numbers. Your health history and plan choice change the rest.

FAQ

Is Medicare free at 65?

No. Part A has no premium for most people, but Part B, Part D, and any supplemental coverage all carry a cost. "Free" only applies to one piece of the whole picture.

What is the average total Medicare cost per month?

Most people pay somewhere between $200 and $450 a month total once Part B, a drug plan, and a supplement or Advantage plan are all factored in. Income and health history move that number in either direction.

Does Medicare cost more if I'm still working at 65?

Not because you're working, but if your income is high enough to trigger IRMAA, yes. The premium is based on income, not employment status.

Can I lower my Medicare Part B premium?

If a specific life event dropped your income since the tax return used to calculate IRMAA (retirement, divorce, loss of a pension), you can file for a reconsideration using Form SSA-44. Otherwise the premium is set by law.

The Actual Next Step

These are the federal numbers. What you'll pay depends on your income, your health, and which supplement or Advantage plan fits your situation, and that's not something a table can answer for you.
