Medicare Costs Breakdown (2026)

Part A (Hospital): $0 premium for most people (if you or spouse paid Medicare taxes 10+ years). Covers inpatient hospital stays with deductibles ($1,632 per benefit period in 2025). Part B (Medical): Standard premium $185/month (2026 est.). Covers doctor visits, outpatient care, preventive services. 80/20 cost sharing after $240 annual deductible. Part D (Prescription): $30-90/month depending on plan. Covers medications with varying copays and a coverage gap.

IRMAA — The High-Income Surcharge

If your Modified Adjusted Gross Income exceeds $103,000 (single) or $206,000 (joint), you pay Income-Related Monthly Adjustment Amounts (IRMAA) — surcharges of $74-$444/month on top of standard Part B premiums. IRMAA is based on your tax return from 2 years prior. A one-time income spike (selling a home, Roth conversion, business sale) can trigger IRMAA — plan large income events carefully around Medicare enrollment.
