How to use this tool?
This guide explains how to use the AGI Calculator to compute your Adjusted Gross Income (AGI). AGI is a key figure in US taxes, calculated as your total income minus specific adjustments.
- Enter Total Income: Input your total income for the year (e.g., wages, salaries, tips). Use a positive number, like
75000. This field is required. - Enter Adjustments: Input your total adjustments (e.g., IRA contributions, student loan interest). Use a positive number or leave as
0. This field is optional but must be a valid number. - Click "Calculate AGI": Press the button to compute your AGI. The result will display in green, along with a breakdown showing the formula:
AGI = Total Income - Adjustments. - Review the Result: The AGI appears formatted with commas and two decimal places (e.g.,
$70,000.00). If adjustments exceed total income, an error message will appear—correct your inputs.
Important Notes:
- All values must be in US dollars ($) and cannot be negative.
- Inputs are validated: invalid or negative numbers trigger a red error state.
- The calculator posts the result to the parent window for integration purposes.

Frequently Asked Questions
Adjusted Gross Income (AGI) is your total gross income minus specific adjustments (e.g., IRA contributions, student loan interest). It is used to determine your taxable income and eligibility for certain tax credits.
Common adjustments include contributions to traditional IRAs, student loan interest paid, educator expenses, health savings account contributions, and alimony paid (for agreements before 2019).
AGI is the starting point for calculating your taxable income and determines eligibility for many tax deductions and credits, such as the Earned Income Tax Credit and Child Tax Credit.
