Adjustable Gross Income Calculator

Understanding your Adjusted Gross Income (AGI) is a vital step in preparing your taxes, qualifying for credits, and making smart financial decisions. Whether you’re an employee, freelancer, or small business owner, knowing your AGI gives you clarity on your tax liability and eligibility for deductions and credits.

🧾 What Is Adjusted Gross Income (AGI)?

Adjusted Gross Income (AGI) is your total gross income minus certain deductions (adjustments) allowed by the IRS. It is a key figure on your federal tax return and determines your:

• Taxable income
• Eligibility for tax credits (like Child Tax Credit, EITC)
• Ability to contribute to Roth IRAs
• Student loan interest deductions
• Medicare premiums and more

📌 What the AGI Calculator Does

The AGI Calculator takes your gross income and subtracts specific IRS-approved adjustments to give you an accurate estimate of your AGI.

These adjustments can include:

• Educator expenses
• Student loan interest
• Traditional IRA contributions
• Health savings account (HSA) contributions
• Alimony paid (pre-2019 divorces)
• Self-employment tax deduction
• Moving expenses (military only)

The calculator provides a clear breakdown of your AGI, helping you prepare your taxes more accurately or check your eligibility for certain benefits.

🔢 Formula for AGI

The basic formula is:

Adjusted Gross Income (AGI) = Gross Income − Adjustments to Income

Where:

• Gross Income includes wages, salaries, tips, business income, rental income, dividends, and interest.
• Adjustments to Income include allowable deductions listed above.

Example:

• Gross Income: $75,000
• Student Loan Interest Deduction: $2,000
• IRA Contribution: $5,000
• HSA Contribution: $1,200

AGI = 75,000 − (2,000 + 5,000 + 1,200) = $66,800

📊 Common Adjustments to Income (Deductions for AGI)

🧮 Real-Life Examples

💼 Example 1: Salaried Individual

• Gross Income: $70,000
• IRA Contribution: $6,000
• Student Loan Interest: $2,000

AGI = 70,000 − (6,000 + 2,000) = $62,000

👨‍🔧 Example 2: Self-Employed Freelancer

• Gross Income: $90,000
• HSA: $3,000
• SE Tax Deduction: $6,800
• SEP IRA: $8,000

AGI = 90,000 − (3,000 + 6,800 + 8,000) = $72,200

📚 Why Is AGI Important?

1. Determines Tax Bracket: AGI impacts how much income is taxed.
2. Controls Deduction Limits: Some deductions phase out at higher AGIs.
3. Eligibility for Tax Credits: Many credits (like EITC or Child Tax Credit) are income-limited.
4. IRAs and Roth IRAs: Contribution eligibility is based on AGI.
5. Student Aid and FAFSA: Federal aid calculations often depend on AGI.

⚠️ Tips for Lowering AGI

• Max out traditional IRA or 401(k) contributions
• Use an HSA if you have a high-deductible health plan
• Deduct student loan interest
• Claim self-employed business deductions
• Keep receipts for educator expenses if you’re a teacher
