Calculate Your IRMAA
Enter your MAGI from your tax return. This is typically your adjusted gross income plus certain tax-exempt interest and other excluded income.
Your tax filing status directly impacts the IRMAA income thresholds.
IRMAA for a given year is based on your MAGI from two years prior. E.g., 2024 IRMAA uses 2022 MAGI.
Your Estimated Medicare IRMAA
The calculation determines your IRMAA tier based on your Modified Adjusted Gross Income (MAGI) and filing status for the selected tax year. The Part B IRMAA is added to the standard Part B premium. The Part D IRMAA is an additional amount added to your Part D plan's premium. A standard Part D premium is not included as it varies significantly by plan.
| Income Range (MAGI) | Monthly Part B IRMAA | Monthly Part D IRMAA | Total Monthly Part B Premium |

Projected Monthly Medicare Part B Premium vs. MAGI
A) What is IRMAA Medicare?
The Income-Related Monthly Adjustment Amount, or IRMAA, is an additional premium that some Medicare beneficiaries pay for their Part B (medical insurance) and Part D (prescription drug coverage) coverage. It's a key component of your overall Medicare costs, designed to ensure that those with higher incomes contribute more to their Medicare premiums.
Essentially, if your Modified Adjusted Gross Income (MAGI) exceeds certain thresholds, the Social Security Administration (SSA) will notify you that you owe an IRMAA. This adjustment is added directly to your standard Part B premium and, if applicable, to your chosen Part D plan's premium.
Who Should Use This IRMAA Medicare Calculator?
- Individuals nearing Medicare eligibility who want to project their future premiums.
- Current Medicare beneficiaries who have experienced significant income changes (e.g., retirement, sale of assets) and want to understand their potential IRMAA impact.
- Financial planners assisting clients with retirement planning and budgeting.
- Anyone curious about how their income affects their Medicare expenses.
Common Misunderstandings About IRMAA
One common misunderstanding is that IRMAA affects all parts of Medicare. It only applies to Part B and Part D. Another misconception is that IRMAA is based on current income. In reality, IRMAA for a given year is based on your MAGI from two years prior (e.g., 2024 IRMAA is based on 2022 MAGI). Unit confusion is rare as IRMAA is always calculated in U.S. Dollars (USD), but understanding the "two-year look-back" period is crucial.
B) IRMAA Medicare "Formula" and Explanation
Unlike a simple mathematical formula, IRMAA is determined by a tiered system based on your Modified Adjusted Gross Income (MAGI) and your tax filing status. There isn't a single "IRMAA Medicare formula" but rather a set of income brackets that determine the additional amount you pay. Each bracket has a specific IRMAA for Part B and Part D.
The core concept is: Your Medicare Part B Premium = Standard Part B Premium + Part B IRMAA, and Your Medicare Part D Premium = Your Plan's Premium + Part D IRMAA.
Our IRMAA Medicare Calculator uses the official income thresholds provided by the Social Security Administration for the selected tax year to find your applicable tier.
Key Variables and Their Meanings:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| MAGI | Modified Adjusted Gross Income (AGI + tax-exempt interest + excluded foreign income + other excluded income) | USD | $0 - $1,000,000+ |
| Filing Status | Your tax filing status (Single, Married Filing Jointly, etc.) | Unitless | Specific categories |
| Tax Year | The year for which IRMAA is being calculated (based on MAGI from two years prior) | Year | Current and recent past years |
| Standard Part B Premium | The base monthly premium for Medicare Part B for those not subject to IRMAA | USD/month | Varies by year (e.g., $174.70 in 2024) |
| Part B IRMAA | The additional monthly amount added to your Part B premium due to higher MAGI | USD/month | $0 - $443.30+ (2024) |
| Part D IRMAA | The additional monthly amount added to your Part D premium due to higher MAGI | USD/month | $0 - $81.00+ (2024) |
C) Practical Examples
Let's illustrate how the IRMAA Medicare Calculator works with a couple of scenarios:
Example 1: Moderate Income, Married Filing Jointly
- Inputs:
- Modified Adjusted Gross Income (MAGI): $220,000
- Tax Filing Status: Married Filing Jointly
- Relevant Tax Year: 2024 (based on 2022 MAGI)
- Calculation:
For 2024, Married Filing Jointly, a MAGI of $220,000 falls into the second IRMAA tier ($206,001 - $258,000).
- Standard Part B Premium (2024): $174.70
- Part B IRMAA Adjustment: $69.90
- Part D IRMAA Adjustment: $12.90
- Results:
- Total Part B Monthly Premium: $174.70 + $69.90 = $244.60
- Total Part D IRMAA: $12.90 (added to plan premium)
- Estimated Total Monthly Medicare Premium (Part B + Part D IRMAA): $244.60 + $12.90 = $257.50
Example 2: Higher Income, Single Filer
- Inputs:
- Modified Adjusted Gross Income (MAGI): $170,000
- Tax Filing Status: Single
- Relevant Tax Year: 2023 (based on 2021 MAGI)
- Calculation:
For 2023, Single Filer, a MAGI of $170,000 falls into the fourth IRMAA tier ($153,001 - $183,000).
- Standard Part B Premium (2023): $164.90
- Part B IRMAA Adjustment: $263.70
- Part D IRMAA Adjustment: $50.70
- Results:
- Total Part B Monthly Premium: $164.90 + $263.70 = $428.60
- Total Part D IRMAA: $50.70 (added to plan premium)
- Estimated Total Monthly Medicare Premium (Part B + Part D IRMAA): $428.60 + $50.70 = $479.30

E) Key Factors That Affect IRMAA
Understanding the factors that influence your IRMAA is crucial for Medicare planning and managing your healthcare costs.
- Modified Adjusted Gross Income (MAGI): This is the most significant factor. Your MAGI is your Adjusted Gross Income (AGI) plus certain tax-exempt interest and other excluded income. The higher your MAGI, the higher your potential IRMAA.
- Impact: Direct correlation. As MAGI crosses thresholds, IRMAA increases.
- Units/Scaling: USD, income tiers are set in USD.
- Tax Filing Status: Your filing status (Single, Married Filing Jointly, etc.) determines which set of income thresholds applies to you. Thresholds for joint filers are generally double those for single filers.
- Impact: Defines the applicable IRMAA tier schedule.
- Relevant Tax Year: IRMAA is always based on your MAGI from two years prior. For instance, your 2024 IRMAA is determined by your 2022 MAGI. This "look-back" period is essential to remember.
- Impact: Thresholds and standard premiums change annually.
- Units/Scaling: Annual changes in USD for thresholds and premiums.
- Life-Changing Events: Certain events can lead to a reduction in your MAGI that the SSA may consider for an IRMAA appeal. These include marriage, divorce/annulment, death of a spouse, work stoppage or reduction, loss of income-producing property, or receipt of a settlement payment.
- Impact: Can reduce or eliminate IRMAA if an appeal is successful.
- Social Security Benefits: If you receive Social Security benefits, your Part B premium (including IRMAA) is usually deducted directly from your monthly payment.
- Impact: Method of premium payment.
- Appeals Process: If you believe your IRMAA is incorrect due to a life-changing event that reduced your income, you can file an appeal with the SSA using Form SSA-44, "Medicare Income-Related Monthly Adjustment Amount - Life-Changing Event."
- Impact: Provides a mechanism to adjust IRMAA if circumstances warrant.
F) Frequently Asked Questions About IRMAA Medicare
Q1: What does IRMAA stand for?
A: IRMAA stands for Income-Related Monthly Adjustment Amount. It's an additional premium for Medicare Part B and Part D based on your income.
Q2: How is my income for IRMAA calculated?
A: Your income for IRMAA is your Modified Adjusted Gross Income (MAGI) as reported to the IRS. This includes your Adjusted Gross Income (AGI) plus tax-exempt interest and certain other exclusions.
Q3: Which tax year's income does IRMAA use?
A: IRMAA is based on your MAGI from two years prior to the year you're paying premiums. For example, 2024 IRMAA is based on your 2022 MAGI.
Q4: Does IRMAA apply to Medicare Part A or Medicare Advantage?
A: No, IRMAA only applies to Medicare Part B (medical insurance) and Medicare Part D (prescription drug coverage). It does not affect Part A (hospital insurance) or Medicare Advantage (Part C) premiums directly, though if you have a Part C plan, you still pay your Part B premium (including IRMAA) to Medicare.
Q5: Can I appeal my IRMAA decision?
A: Yes, you can appeal your IRMAA decision if you've experienced a life-changing event that significantly reduced your income. You would typically file Form SSA-44 with the Social Security Administration.
Q6: Are the income thresholds for IRMAA adjusted annually?
A: Yes, the IRMAA income thresholds and the standard Medicare Part B premiums are typically adjusted annually by the Social Security Administration.
Q7: Why doesn't the calculator include a standard Part D premium?
A: Standard Part D premiums vary significantly based on the specific plan you choose, your location, and the formulary. The calculator only estimates the IRMAA portion of your Part D premium, which is consistent regardless of your chosen plan.
Q8: What happens if my MAGI is just slightly over an IRMAA threshold?
A: Even if your MAGI is just one dollar over an IRMAA threshold, you will be subject to the higher IRMAA for that tier. This highlights the importance of understanding the exact income limits.
