Medicare Part D Late Enrollment Penalty (LEP) Calculator

HOW MUCH IS THE LEP FOR PART D?

The Medicare Part D penalty is based on the number of months without PDP coverage. For each month without coverage, an additional premium of 1 percent of the current “national base beneficiary premium” is assessed. For 2021, the average Part D premium is $33.06; up from the 2020 premium of $32.74.

If assessed this penalty, it is paid every month for as long as Medicare prescription coverage is in effect. The Medicare Part D penalty will be rounded to the nearest $.10 and added to any Part D premium. Because the LEP is based on the current year’s national beneficiary premium, it may change or go up each year.
