Definition
Adjusted Gross Income (AGI) is a person’s total income from all sources minus certain allowable deductions, and it serves as the primary baseline used to determine taxable income and eligibility for many tax credits and government programs.
Why It Matters
AGI is one of the most important figures in personal finance and taxation because it influences tax brackets, deduction limits, credit eligibility, and financial aid calculations. A lower AGI can reduce total tax liability and increase access to income-based benefits.
Example
If a person earns $60,000 in total income but deducts $5,000 in student loan interest and retirement contributions, their adjusted gross income becomes $55,000. Taxes and eligibility calculations are then based on this reduced amount.
