Medicare is not entirely free at age 65, but one major part of it can be. Most people pay no monthly premium for Part A (hospital coverage) because they or a spouse paid Medicare taxes during their working years. Every other component of Medicare carries monthly premiums, deductibles, or both.
What Makes Part A Free for Most People
Part A covers hospital stays, skilled nursing care, and hospice. You qualify for premium-free Part A if you earned at least 40 work credits through Social Security, which translates to roughly 10 years of employment where Medicare taxes were withheld. Credits earned by your spouse count too, so even if you didn’t work a full decade yourself, you may still qualify through a current or former spouse’s record.
If you don’t have 40 credits, Part A isn’t free. People with 30 to 39 credits pay a reduced monthly premium, while those with fewer than 30 credits pay the full amount. Even with premium-free Part A, you still face out-of-pocket costs when you actually use hospital services. In 2025, the hospital deductible is $1,676 per benefit period. If a hospital stay stretches beyond 60 days, you also pay $419 per day for days 61 through 90, and $838 per day after that for lifetime reserve days.
Part B Has a Monthly Premium Everyone Pays
Part B covers doctor visits, outpatient care, lab tests, and preventive screenings. Unlike Part A, there is no free version. The standard monthly premium for 2026 is $202.90, and it comes with a $283 annual deductible before coverage kicks in. After that, you typically pay 20% of covered services with no annual cap on out-of-pocket spending under Original Medicare.
If your income is higher, you’ll pay more. Medicare uses your tax return from two years prior to determine whether you owe a surcharge on top of the standard premium. This income-related adjustment applies to individuals and couples above certain thresholds and can significantly increase your monthly cost.
Prescription Drug Coverage Costs Extra
Medicare doesn’t include prescription drug coverage automatically. Part D plans are sold by private insurers and carry their own premiums, deductibles, and copays. The national base premium for 2025 is $36.78 per month, though your actual cost depends on which plan you choose. Some plans charge more for broader drug coverage or lower copays at the pharmacy counter.
Part D also has an income-related surcharge for higher earners, similar to Part B. And if you go 63 or more consecutive days without creditable drug coverage and enroll later, you’ll pay an extra 1% of the base premium for every month you waited. That penalty sticks with you for as long as you have Part D coverage.
Medicare Advantage: A Different Cost Structure
Medicare Advantage plans (Part C) are an alternative to Original Medicare offered by private insurers. Many are advertised as “zero-premium” plans, meaning you pay no additional monthly fee beyond your Part B premium. You still must pay the $202.90 Part B premium to enroll in any Medicare Advantage plan. These plans often bundle prescription drug coverage and may include dental, vision, or hearing benefits that Original Medicare does not cover. The tradeoff is usually a narrower provider network and different cost-sharing rules.
Penalties for Signing Up Late
Missing your enrollment window doesn’t just delay your coverage. It permanently raises your costs. The Part B late enrollment penalty adds 10% to your monthly premium for every full year you were eligible but didn’t sign up. That increase lasts for the rest of the time you have Part B.
Part A penalties work slightly differently. If you have to buy Part A and don’t sign up when first eligible, your premium increases by 10%, and you pay the higher amount for twice the number of years you delayed. Part D penalties add 1% per month of delay, which works out to 12% per year, and that surcharge also follows you indefinitely.
These penalties don’t apply if you had qualifying coverage through an employer or union during the gap. But if you simply didn’t sign up because you thought you’d handle it later, the financial consequences compound over time.
Help Paying Medicare Costs
If your income is limited, Medicare Savings Programs can cover some or all of your premiums, deductibles, and copays. There are four programs with different levels of assistance:
- QMB (Qualified Medicare Beneficiary): Covers Part A premiums, Part B premiums, deductibles, coinsurance, and copays. Available to individuals earning up to $1,350 per month with resources under $9,950 (2026 limits).
- SLMB (Specified Low-Income Medicare Beneficiary): Covers Part B premiums only. Individual income limit of $1,616 per month.
- QI (Qualifying Individual): Also covers Part B premiums, with an individual income limit of $1,816 per month. Only available to people who don’t qualify for other Medicaid benefits.
- QDWI (Qualified Disabled and Working Individual): Covers Part A premiums for people with disabilities who lost premium-free Part A after returning to work.
Limits are slightly higher in Alaska and Hawaii, and many states use more generous eligibility rules than the federal minimums. Even if you think your income is a bit too high, it’s worth checking with your state Medicaid office, as some states exclude certain income types from their calculations.
The Real Cost of Medicare at 65
For a typical person with 40 work credits, the baseline monthly cost of Medicare in 2026 is at least $202.90 for Part B alone. Add a Part D plan and you’re looking at roughly $240 or more per month before you use any services. Once you factor in deductibles, copays, and coinsurance, the average Medicare beneficiary spends thousands of dollars annually on healthcare despite having coverage. Many people buy supplemental insurance (Medigap) to help cover those gaps, which adds another monthly premium to the total.
So while the hospital coverage portion of Medicare can genuinely be free at 65, the full picture involves ongoing costs that add up quickly. Planning for those expenses before you turn 65 gives you the best chance of choosing the right combination of coverage for your budget.
