What Is Adjustable Gross Income (AGI)?
Adjustable Gross Income (AGI) is your total income after subtracting eligible deductions or adjustments. It is a key figure used in tax systems to determine how much taxable income you have.
AGI is not your final tax amount but a critical step in calculating it.
In simple terms:
AGI = Total Income − Adjustments (Deductions)
Why Is AGI Important?
Your AGI affects many financial and tax-related decisions, including:
- Federal and state tax calculations
- Eligibility for tax credits
- Loan approvals (mortgage, personal loans)
- Financial aid applications
- Insurance premium assessments
- Retirement contribution limits
A lower AGI can often result in tax savings and better financial benefits.

AGI Formula Explained
The AGI calculation follows a simple financial formula:
Step 1: Total Income Formula
Total Income = Annual Income + Additional Income
Step 2: AGI Formula
AGI = Total Income − Adjustments
Example Formula Breakdown
Suppose:
- Annual Income = $50,000
- Additional Income = $5,000
- Adjustments = $8,000
Step 1: Total Income
50,000 + 5,000 = 55,000
Step 2: AGI Calculation
55,000 − 8,000 = 47,000
Final AGI = $47,000
AGI Calculation Examples
Example 1: Salaried Employee
| Category | Amount |
|---|---|
| Annual Income | $60,000 |
| Additional Income | $2,000 |
| Adjustments | $10,000 |
Calculation:
Total Income = 60,000 + 2,000 = 62,000
AGI = 62,000 − 10,000 = 52,000
Example 2: Freelancer Income
| Category | Amount |
|---|---|
| Annual Income | $40,000 |
| Additional Income | $8,000 |
| Adjustments | $5,000 |
Calculation:
Total Income = 40,000 + 8,000 = 48,000
AGI = 48,000 − 5,000 = 43,000
Example 3: Small Business Owner
| Category | Amount |
|---|---|
| Annual Income | $80,000 |
| Additional Income | $10,000 |
| Adjustments | $20,000 |
Calculation:
Total Income = 80,000 + 10,000 = 90,000
AGI = 90,000 − 20,000 = 70,000
AGI Calculation Table (Quick Reference)
| Annual Income | Additional Income | Adjustments | Final AGI |
|---|---|---|---|
| $30,000 | $0 | $3,000 | $27,000 |

| $70,000 | $10,000 | $15,000 | $65,000 |
| $100,000 | $12,000 | $20,000 | $92,000 |
| $120,000 | $15,000 | $25,000 | $110,000 |
What Are Adjustments in AGI?
Adjustments are expenses that reduce your total taxable income. Common adjustments include:
- Retirement plan contributions
- Student loan interest
- Educator expenses
- Health savings account contributions
- Self-employment tax deductions
- Moving expenses (if applicable)
These deductions directly lower your AGI and may reduce your tax burden.
Difference Between Income and AGI
Many people confuse income with AGI. Here’s the difference:
| Term | Meaning |
|---|---|
| Income | Total earnings before deductions |
| AGI | Income after subtracting eligible adjustments |
Key Point:
AGI is always equal to or less than total income.
