A Modified Adjusted Gross Income (MAGI) Calculator is a financial and tax-planning tool that estimates your Modified Adjusted Gross Income (MAGI). MAGI is a figure used by the IRS and other organizations to determine eligibility for certain tax benefits, deductions, credits, and retirement account contributions.
What Is MAGI?
MAGI starts with your Adjusted Gross Income (AGI) and then adds back certain deductions or exclusions.
Basic Formula
MAGI=AGI+Certain Added-Back Deductions
The exact calculation can vary depending on the tax benefit or program being evaluated.
What Is Adjusted Gross Income (AGI)?
AGI is your total income minus certain eligible adjustments, such as:
- Student loan interest deductions
- Traditional IRA contributions
- Educator expenses
- Health Savings Account (HSA) contributions
- Self-employment deductions
Common Add-Backs for MAGI
Depending on the purpose, a MAGI calculator may add back:
- Foreign earned income exclusions
- Foreign housing exclusions
- Student loan interest deductions
- IRA contribution deductions
- Tuition and fees deductions
- Certain passive income losses
Example Calculation
Suppose:
- Gross income: $80,000
- Adjustments: $5,000
AGI:80,000−5,000=$75,000
If you must add back:
- Student loan interest deduction: $1,500
- Foreign income exclusion: $2,000
MAGI:75,000+1,500+2,000=$78,500
Your MAGI is $78,500.
Why Is MAGI Important?
MAGI is used to determine eligibility for:
Roth IRA Contributions
Your MAGI affects whether you can contribute directly to a Roth IRA and how much you may contribute.
Traditional IRA Deductions
MAGI helps determine whether IRA contributions are fully deductible.
Premium Tax Credits
Health insurance subsidies may depend on your MAGI.
Education Tax Benefits
Certain education credits and deductions use MAGI limits.
