IRMAA Table

IRMAA Table is a free browser Medicare IRMAA calculator. Enter MAGI and filing status to see the projected Part B and Part D income-related surcharge tier, labeled 2026 official and 2027 projected brackets, and how close you are to the next $1 cliff. 2026 amounts follow the CMS fact sheet; 2027 thresholds are projections and the 2027 calculator labels 2026 rates as placeholders until CMS publishes new amounts. No account needed. It is an independent educational site, not a government agency and not licensed financial advice.
