The amount of the late enrollment penalty is calculated based on how long you went without Part D or creditable prescription drug coverage. The penalty is calculated by multiplying 1% of the “national base beneficiary premium” ($32.74 in 2020, $33.06 in 2021) times the number of full, uncovered months you didn’t have Part D or creditable coverage. The national base beneficiary premium can change from year to year, so your penalty amount may change as well.
