IRRMA Calculator
Understanding Hospital Indemnity Insurance
If your income is above certain limits, you may pay more for Medicare Part B and Part D through what is known as the Income-Related Monthly Adjustment Amount (IRMAA). This additional amount is determined by the Social Security Administration based on your Modified Adjusted Gross Income (MAGI) and tax filing status. Because Medicare generally looks at your tax return from two years prior, changes in your income may affect what you pay for Medicare even if your financial situation is different today.
Understanding how IRMAA may affect your Medicare costs can make it easier to plan ahead and avoid surprises. The calculator below provides a simple way to estimate your potential IRMAA based on the information you enter. It will show your estimated Part B premium, Part B and Part D IRMAA surcharges, and the potential monthly and annual impact of IRMAA. Your actual costs are determined by Social Security, but this tool can give you a helpful starting point for understanding what you may expect to pay.
Estimate your 2026 Medicare Part B and Part D IRMAA surcharge based on your 2024 income.
Your Estimated 2026 Medicare Costs
This Part D amount is in addition to the premium charged by your Medicare prescription drug plan.
Medicare generally determines your IRMAA using the Modified Adjusted Gross Income reported on your federal tax return from two years prior. For 2026 Medicare premiums, this generally means your 2024 income.
Certain life-changing events, such as retirement, marriage, divorce, death of a spouse, or loss of income-producing property, may allow you to request that Social Security reconsider an IRMAA determination.
This calculator is provided for educational and informational purposes only and provides an estimate based on published 2026 Medicare IRMAA amounts. It is not tax, legal, financial, or Medicare advice. Your actual Medicare premiums and IRMAA determination are established by the Social Security Administration and may differ based on your individual circumstances.
