The Federal Adjusted Gross Income (AGI) Calculator is a powerful financial tool designed to help individuals estimate their taxable income after applying allowable adjustments.

Whether you are a salaried employee, freelancer, business owner, or investor, understanding your AGI is essential for accurate tax planning. This calculator simplifies the process by allowing users to input their income sources and adjustments to automatically compute their adjusted gross income.
Instead of manually calculating complex tax formulas, the Federal AGI Calculator provides a fast, reliable, and error-free solution for financial planning and tax preparation.
What is Adjusted Gross Income (AGI)?

AGI includes:

- Retirement income (partially taxable portions)
Then, certain deductions are subtracted, such as:
- Student loan interest
- Educator expenses
- IRA contributions
- Health savings account (HSA) contributions
- Self-employed health insurance premiums

AGI = Total Income − Income Adjustments

Practical Example
Let’s understand AGI with a simple example:
Income:
- Salary: $60,000
- Freelance income: $10,000
- Dividends: $2,000
Total Income = $72,000
Adjustments:
- IRA contribution: $3,000
- Student loan interest: $1,000
Total Adjustments = $4,000
AGI Calculation:
AGI = $72,000 − $4,000 = $68,000
So, the user’s Federal Adjusted Gross Income is $68,000.
