Medicare Premium Calculator

How to Use This Tool

Follow these steps to get an accurate estimate of your Medicare premiums:

• Select your tax filing status from the dropdown menu to apply the correct IRMAA income thresholds.
• Enter your annual Modified Adjusted Gross Income (MAGI) from your most recent federal tax return.
• Choose your coverage type: Part B only, Part D only, or both Part B and Part D.
• If you select Part D coverage, enter the monthly premium for your chosen Part D plan (check your plan documents for this amount).
• Click the Calculate Premiums button to see your detailed breakdown.
• Use the Reset Form button to clear all inputs and start over.
• Click Copy Results to Clipboard to save your breakdown for budgeting or discussions with a financial planner.

Formula and Logic

This calculator uses 2024 Medicare standard premium rates and IRMAA (Income-Related Monthly Adjustment Amount) tiers published by the Centers for Medicare & Medicaid Services (CMS).

Part B Premium Calculation: Standard Part B premium + applicable Part B IRMAA surcharge based on MAGI and filing status.

Part D Premium Calculation: Your plan-specific Part D premium + applicable Part D IRMAA surcharge based on MAGI and filing status.

Total Premium: Sum of Part B and Part D premiums (depending on selected coverage). Annual premium is total monthly premium multiplied by 12.

IRMAA surcharges apply when your MAGI exceeds certain thresholds for your filing status. Higher income levels correspond to higher IRMAA tiers.

Practical Notes

Keep these finance-specific tips in mind when using your results:

• Medicare premiums and IRMAA thresholds are updated annually, so recalculate each year during open enrollment.
• IRMAA is based on MAGI from two years prior (e.g., 2024 premiums use 2022 tax return data), so plan ahead for income changes.
• Part D plan premiums vary widely by provider and coverage level, so use your actual plan premium for the most accurate estimate.
• IRMAA surcharges apply to each covered individual: if both spouses are enrolled in Medicare, each may pay separate IRMAA based on joint MAGI.
• You can appeal an IRMAA surcharge if your income has decreased due to a life-changing event (marriage, divorce, death of a spouse, work stoppage).
• Include Medicare premiums in your monthly budget planning to avoid unexpected healthcare costs in retirement.

Why This Tool Is Useful

Medicare premium costs can vary significantly based on income and coverage choices, making manual calculations error-prone.

This tool helps you avoid surprises by estimating your exact premiums before you enroll, so you can adjust your budget or income planning in advance.

Financial planners and individuals managing retirement budgets can use this tool to model different income scenarios and their impact on healthcare costs.

It also clarifies how IRMAA surcharges work, which is often a confusing part of Medicare planning for higher-income beneficiaries.

Frequently Asked Questions

What is MAGI for Medicare purposes?

Modified Adjusted Gross Income (MAGI) for Medicare is your adjusted gross income plus tax-exempt interest income. It is the same figure used for most federal income tax calculations, and you can find it on your federal tax return.

Can I avoid IRMAA surcharges?

IRMAA surcharges are mandatory for beneficiaries with MAGI above the published thresholds for their filing status. You cannot opt out, but you can appeal if your income has dropped due to a qualifying life event.

Are Medicare premiums tax-deductible?

Yes, Medicare premiums (Part B, Part D, and Medigap) are tax-deductible as medical expenses if you itemize deductions and your total medical expenses exceed 7.5% of your adjusted gross income.

Additional Guidance

Always verify your premium estimates with the official Medicare.gov premium calculator or your Social Security Administration (SSA) notice, as this tool provides estimates only.

If you expect your income to change significantly in the next two years, run calculations for multiple MAGI scenarios to see how it will affect your future premiums.

Combine this tool with a retirement budget calculator to get a full picture of your expected healthcare and living costs in retirement.
