This calculator is for educational purposes only and uses 2026 Medicare IRMAA figures. It estimates Part B and Part D income-related monthly adjustment amounts based on modified adjusted gross income. It does not determine your official Medicare premium, does not include any separate Part D plan premium, and does not address appeals, life-changing events, amended tax returns, late enrollment penalties, or state-specific programs.
