How do you calculate your premium penalty?

Let’s say you delayed enrollment in Part D for seven months (and you do not meet any of the exceptions listed above). Your monthly premium would be 7% higher for as long as you have Part D (7 months x 1%). The national base beneficiary premium in 2025 is $36.78 a month. Your monthly premium penalty would therefore be $2.57 ($36.78 x 0.07 = $2.57) per month, which you would pay in addition to your plan’s premium.

Note: The Part D penalty is always calculated using the national base beneficiary premium. Your penalty will not decrease if you enroll in a Part D plan with a lower premium.
