Comprehensive Calculation Guide & Methodology
In-depth mathematical breakdowns, statutory formulas, and real-world scenarios.
Use this 2026 Medicare Premium Calculator to estimate your monthly premiums for Medicare Part B and Part D, including any Income-Related Monthly Adjustment Amounts (IRMAA). This tool is designed for individuals and couples enrolled in Medicare, helping you understand how your Modified Adjusted Gross Income (MAGI) from two years prior (e.g., 2026 MAGI for 2026 premiums) affects your out-of-pocket costs.
Understanding Your 2026 Medicare Premiums
Medicare Part B covers most outpatient medical services, while Part D covers prescription drugs. While a standard premium applies to most beneficiaries, those with higher incomes may pay an additional amount known as the Income-Related Monthly Adjustment Amount (IRMAA) for both Part B and Part D. This calculator helps you determine if IRMAA applies to you and what your total estimated monthly premium will be for 2026, based on your 2026 tax information.
The Centers for Medicare & Medicaid Services (CMS) sets the standard Part B premium and the IRMAA thresholds annually. Your specific premium is determined by your Modified Adjusted Gross Income (MAGI) from two years prior to the current Medicare year. For 2026 premiums, your 2026 MAGI and tax filing status are used to assess if you owe IRMAA.

How Medicare Premiums Are Calculated
Your 2026 Medicare Part B and Part D premiums are determined by a combination of the standard premium set by CMS and any applicable Income-Related Monthly Adjustment Amount (IRMAA).
1. Standard Part B Premium: For 2026, most Medicare beneficiaries will pay a standard monthly Part B premium. This amount is set annually by CMS.
2. Modified Adjusted Gross Income (MAGI): Your MAGI is calculated from your most recent tax return (e.g., your 2026 MAGI for 2026 premiums). It includes your Adjusted Gross Income (AGI) plus any tax-exempt interest income.
3. Income-Related Monthly Adjustment Amount (IRMAA): If your MAGI exceeds certain thresholds, you will pay an additional amount called IRMAA for both Part B and Part D. These thresholds vary based on your tax filing status. There are several income tiers, and as your income increases, so does your IRMAA.
The calculation process involves:
- Identifying your MAGI and filing status: These inputs determine which IRMAA tier, if any, you fall into.
- Applying the standard Part B premium: This is the base amount everyone pays.
- Calculating Part B IRMAA: Based on your MAGI and filing status, a specific IRMAA amount is added to your standard Part B premium.
- Calculating Part D IRMAA: A separate IRMAA amount is calculated for Part D, also based on your MAGI and filing status. This is added to your Part D plan’s premium (which is not calculated here, but the IRMAA portion is estimated).
- Summing up: Your total estimated monthly premium includes the standard Part B premium, Part B IRMAA, and Part D IRMAA.
Key Variables Explained:
- Tax Filing Status: Your status (e.g., Single, Married Filing Jointly) as reported on your most recent tax return. This is crucial for determining the correct IRMAA income thresholds.
- Modified Adjusted Gross Income (MAGI): Your AGI plus tax-exempt interest. This is the income figure Medicare uses to determine if you owe IRMAA.
- Standard Part B Premium: The base monthly cost for Medicare Part B, applicable to most beneficiaries.
- Part B Income-Related Monthly Adjustment Amount (IRMAA): An additional amount added to your Part B premium if your MAGI exceeds certain thresholds.
- Part D Income-Related Monthly Adjustment Amount (IRMAA): An additional amount added to your Part D premium if your MAGI exceeds certain thresholds. This is paid directly to Medicare, not your Part D plan.
- Total Monthly Premium (Part B + Part D IRMAA): Your estimated total monthly cost for Medicare Part B and the IRMAA portion of Part D.

Important Notes and Tips
- Income Look-Back: Medicare uses your MAGI from two years prior to determine your IRMAA. For 2026 premiums, your 2026 MAGI is used.
- Life-Changing Events: If you’ve experienced a life-changing event (e.g., marriage, divorce, death of a spouse, work stoppage) that significantly reduced your income since your 2026 tax return, you may be able to appeal your IRMAA decision with the Social Security Administration.
- Part D Plan Premiums: This calculator estimates your Part D IRMAA, but it does not include the base premium charged by your specific Part D prescription drug plan. You will pay your Part D plan’s premium directly to your plan provider, in addition to any Part D IRMAA paid to Medicare.
- Medicare Advantage (Part C): If you are enrolled in a Medicare Advantage plan, you still typically pay your Part B premium. This calculator helps determine that cost.
- Premium Withholding: For most beneficiaries, Medicare Part B premiums are automatically deducted from Social Security benefits. If you are not receiving Social Security benefits, you will be billed directly.
