The base monthly premium for Part B will be $185.00, an increase of $10.30 (5.9%) from $174.70 in 2024. The premium is adjusted each year so that, based on the projected expenses of Medicare Part B, the premiums will pay 20% of the total expected costs.

Even with Part D drug coverage, it's common to have to spend money on copays. The good news is that beginning in 2025, Medicare Part D out-of-pocket drug costs will be capped at $2,000. This new rule may not only spell relief, but also help you better work prescription costs into your budget.

Here are the Medicare Parts A and B premiums and deductibles for 2025, as well as information on Part D changes that will affect prescription drug costs.
