Estimate Your Medicare Premiums and Income-Related Surcharges
What is IRMAA?
IRMAA is an additional premium surcharge for Medicare Part B and Part D based on your income. Your 2026 IRMAA is determined by your Modified Adjusted Gross Income (MAGI) from your 2024 tax return, reflecting Medicare’s two-year lookback policy. IRMAA operates as a cliff — exceeding a threshold by even $1 triggers the full surcharge for that tier.
Calculate Your Medicare Income-Related Monthly Adjustment Amount
How IRMAA Works
- Medicare’s Income-Related Monthly Adjustment Amount applies to higher-earning individuals whose income exceeds specific thresholds established annually by the Social Security Administration.
- IRMAA affects both Medicare Part B and Part D premiums.
- The surcharge is determined using your modified adjusted gross income from two years prior, which creates a planning challenge for retirees managing distributions, capital gains, and other taxable events.
A thoughtful approach to income may help reduce IRMAA-related surcharges and support long-term retirement planning. Our Retirement Income Certified Professional, Aaron Simpson, CFP®, RICP®, helps clients sequence withdrawals to manage IRMAA exposure.

The IRMAA Calculator provides a generalized estimate based on the information you input and the Medicare Income-Related Monthly Adjustment Amount (IRMAA) thresholds published by the Centers for Medicare & Medicaid Services. The results are hypothetical and are intended solely for educational and illustrative purposes. They do not constitute financial, tax, or legal advice and may not reflect your actual Medicare premiums or future tax liabilities.
All calculations rely on current IRMAA brackets, premium schedules, and applicable assumptions, which are subject to change at any time. Actual outcomes may vary due to changes in federal law, IRS or SSA methodologies, future income, filing status, deductions, or other personal circumstances.
