Part D Penalty Estimator
Going without creditable drug coverage after you're first eligible adds a permanent Part D penalty — roughly 1% of the national base beneficiary premium for each month you went without. Like the Part B penalty, it lasts for life. Use the estimator below, and we'll help you stay penalty-free even if you don't take medications today.
How the penalty works
Medicare counts the months you went without creditable drug coverage after your Initial Enrollment Period, multiplies by about 1% of the national base premium, and adds that to your Part D premium for life. Because the base premium can rise over time, so can your penalty.
Stay protected
Keep creditable drug coverage — from an employer, the VA, or a Part D plan — and enroll on time. Even if you take no medications, a $0 or low-cost Part D plan now can prevent a much larger penalty later. We help you find the cheapest way to stay protected.
Questions, answered
I don't take any drugs — do I still need Part D?
Often yes, to avoid a lifelong penalty later. A low-cost Part D plan now is usually cheaper than the penalty you'd owe if you enroll after going without coverage.
Does VA drug coverage count?
Yes — VA prescription coverage is creditable, so if you use the VA pharmacy you generally avoid the Part D penalty. We confirm your coverage counts.
How do I avoid the Part D penalty?
Enroll in a Part D plan when first eligible or keep other creditable drug coverage. We track your dates and find you a low-cost plan if you need one.
