Modified Adjusted Gross Income (MAGI) Calculator
Calculate your Modified Adjusted Gross Income (MAGI) to estimate eligibility for tax credits, deductions, and other income-based programs.
What Is Modified Adjusted Gross Income (MAGI)?
Modified Adjusted Gross Income (MAGI) is a calculation used by the IRS and other government agencies to determine eligibility for specific tax credits, deductions, and healthcare programs. It starts with your Adjusted Gross Income (AGI) from your tax return and adds back certain deductions and exclusions. This tool calculates your MAGI based on the income sources and adjustments you provide, giving you a clearer picture of where you stand for programs like premium tax credits, IRA deductions, and student loan interest deductions.
How MAGI Is Calculated
MAGI is not a single fixed formula. The calculation varies depending on the program or credit you are applying for. However, the most common starting point is your AGI. From there, specific items are added back. This tool uses the standard MAGI calculation relevant to healthcare marketplace subsidies and common tax credits.
The general formula is:
MAGI = Adjusted Gross Income (AGI) + Tax-Exempt Interest + Non-Taxable Social Security Benefits + Foreign Earned Income Exclusion + Tax-Exempt Savings Bond Interest
Depending on the specific program, other items like untaxed portions of pensions, IRA deductions, or student loan interest deductions may also be added back. This calculator accounts for the most common adjustments to provide a reliable estimate.

Understanding Your Results
Your calculated MAGI is an estimate based on the information you provided. It is not a substitute for professional tax advice or an official IRS determination. The result is most useful for:
- Healthcare Marketplace: Determining eligibility for premium tax credits and cost-sharing reductions under the Affordable Care Act.
- IRA Deductions: Checking if you qualify for a deductible traditional IRA contribution.
- Student Loan Interest Deduction: Verifying if your income allows you to deduct student loan interest.
- Other Income-Based Programs: Assessing eligibility for various state and federal programs that use MAGI as a threshold.
If your MAGI is close to a program's income limit, consult a tax professional for a precise calculation.
Common Mistakes When Calculating MAGI
- Using gross income instead of AGI: MAGI always starts with your AGI, not your total gross income. Using gross income will overstate your MAGI.
- Forgetting tax-exempt interest: Municipal bond interest is often overlooked but must be added back.
- Omitting foreign earned income exclusion: If you live abroad and use the foreign earned income exclusion, that amount must be included in your MAGI.
- Confusing MAGI with AGI: They are not the same. MAGI is always equal to or higher than your AGI.
- Using the wrong formula: Different programs have slightly different MAGI definitions. This calculator uses the standard definition for healthcare subsidies, but always verify with the specific program's guidelines.
Limitations of This Calculator
This calculator provides an estimate based on the most common MAGI adjustments. It may not account for every possible add-back required by every specific program. For example, some programs may require adding back the untaxed portion of a pension or certain housing allowances. Always cross-reference your results with the official guidelines of the program you are applying for. This tool is for informational purposes and should not be the sole basis for financial decisions.

Frequently Asked Questions
What is the difference between AGI and MAGI?
Adjusted Gross Income (AGI) is your total income minus specific deductions like IRA contributions, student loan interest, and alimony payments. Modified Adjusted Gross Income (MAGI) starts with your AGI and then adds back certain items, such as tax-exempt interest and non-taxable Social Security benefits. MAGI is always equal to or higher than your AGI.
Why does MAGI matter for health insurance?
The Affordable Care Act uses MAGI to determine eligibility for premium tax credits and cost-sharing reductions. Your MAGI is compared to the federal poverty level to see if you qualify for subsidies that lower your monthly insurance premiums and out-of-pocket costs.
Does MAGI affect my IRA contributions?
Yes. Your MAGI determines whether you can deduct contributions to a traditional IRA and whether you can contribute to a Roth IRA. If your MAGI exceeds certain thresholds, your deduction or contribution limit may be reduced or eliminated.
Is MAGI the same for all programs?
No. While the general concept is the same, different programs may add back different items. For example, the healthcare marketplace MAGI typically adds back tax-exempt interest and foreign earned income, while the student loan interest deduction MAGI may add back the student loan interest deduction itself. Always check the specific program's definition.
