How much does Medicare Part D cost?

Part D plans are sold by private companies, so each sets its own monthly premium, the amount you pay to keep coverage. The national base premium used for certain calculations is $38.99 per month in 2026, though individual plan premiums differ. Each plan also sets a deductible up to a maximum of $615 in 2026, and all Part D plans share a yearly out-of-pocket cap of $2,100 in 2026, the most you pay yourself for covered drugs. Because specific premiums and copays depend on the plan and your medications, exact costs differ.
