The real number depends on four things: your premiums, your deductibles, your income (IRMAA), and whether you signed up on time. Here is each piece with 2026 figures.
No. Coverage rules and cost sharing still matter. Before estimating a bill, check whether the service is covered and what conditions apply. The official costs page separates the parts of Medicare and points to the rules for each.
Look beyond the advertised premium. Check the plan documents for deductibles, copayments, coinsurance, covered drugs and provider access. A plan with a low premium may still have costs when you use care. Compare your own expected services rather than assuming the lowest premium means the lowest total cost.
Yes. Prescription coverage can differ between plans. Use Medicare Plan Finder with your actual drugs and pharmacies, then check the plan information. A generic premium comparison does not show whether a particular medicine is covered or how its cost sharing works.
Use Medicare.gov for current program costs and the plan documents for plan-specific costs. This site provides educational estimates and cannot determine your bill. If you need help paying, check the official cost-assistance programs rather than relying on an income threshold copied from another year.

Most people pay $0 for Part A (hospital insurance) because they worked at least 40 quarters (about 10 years) and paid Medicare taxes. If you do owe a premium it can run up to several hundred dollars a month. The 2026 Part A inpatient hospital deductible is $1,736 per benefit period — what you pay before Medicare covers your hospital stay.
The standard 2026 Part B premium is $202.90 per month, with an annual deductible of $283. Higher-income beneficiaries pay more through IRMAA (below). Part B covers doctor visits, outpatient care, and durable medical equipment.
Part D premiums vary by plan; the 2026 national base beneficiary premium is $38.99, which is also what late-enrollment penalties and Part D IRMAA are calculated from. Big news for 2026: prescription out-of-pocket costs are now capped at $2,100 for the year — once you hit it, covered drugs cost you nothing for the rest of the year. (See our donut hole guide.)
If your 2024 income was above $109,000 (single) or $218,000 (married filing jointly), you pay an Income-Related Monthly Adjustment Amount on top of Part B and Part D. It is a cliff — one dollar over a threshold triggers the full higher premium. Use the IRMAA calculator for your exact number.
Sign up late and you can owe a permanent surcharge: 10% of the Part B premium for each full year you delayed, and 1% of the Part D base per uncovered month. These last as long as you have the coverage. The penalty calculator shows the lifetime cost.
