Visit the “Estimate my Medicare eligibility & premium” page on the US Government Medicare website. This will give you an estimate of when you’re eligible for Medicare and your premium amount. If you don’t see your situation, contact Social Security (or the Railroad Retirement Board if you get railroad benefits) to learn more about your specific eligibility or premium.

In general, you qualify for Medicare if you are 65 or older, a U.S. citizen, or a permanent legal resident who’s been in the United States for at least five years, have worked 10 years, and paid Medicare taxes. You may also qualify if you are younger than 65 but are disabled or have certain medical conditions.
