Adjusted Gross Income (AGI) Calculator
Adjusted gross income (AGI) is the figure on line 11 of IRS Form 1040 and the starting point for almost every other tax calculation. It is your total income from all sources minus a set of "above-the-line" adjustments that you can claim whether or not you itemize. This calculator adds up your income, subtracts your adjustments, and shows your AGI. Because the specific dollar amounts depend on your own tax documents, every figure here is a user-editable input: enter the numbers from your W-2s, 1099s and Schedule 1, and the calculator returns your AGI.
AGI formula
Gross income = wages + business + interest/dividends + capital gains + other income Adjustments = IRA/HSA + deductible SE tax + student loan interest + other Schedule 1 items AGI = Gross income - Adjustments
This mirrors IRS Form 1040: total income on line 9, adjustments on line 10 (from Schedule 1), and AGI on line 11.
Worked example
Wages 65,000 plus interest and dividends 1,200 gives gross income of 66,200. Subtract a 3,000 deductible IRA contribution: AGI = 63,200.00.
AGI: frequently asked questions
What is adjusted gross income (AGI)?
Adjusted gross income is your total (gross) income from all sources minus specific 'above-the-line' adjustments allowed by the IRS, such as deductible IRA contributions, the deductible part of self-employment tax, student loan interest, and HSA contributions. AGI appears on line 11 of IRS Form 1040 and is the starting point for figuring taxable income and many credit and deduction phase-outs.
How is AGI different from gross income and taxable income?
Gross income is everything you earned: wages, interest, dividends, business income, capital gains and more. AGI is gross income minus above-the-line adjustments. Taxable income is AGI minus your standard or itemized deduction (and the QBI deduction). Tax is then computed on taxable income, not on AGI.
What are 'above-the-line' adjustments?
These are deductions you can take whether or not you itemize. Common ones include the deductible part of self-employment tax, contributions to a traditional IRA, HSA contributions, student loan interest (up to the IRS limit), educator expenses, and self-employed health insurance and retirement plan contributions. The full list is on Schedule 1 of Form 1040.
Why does my AGI matter?
Many tax benefits phase in or out based on AGI or a modified version of it (MAGI). These include Roth IRA eligibility, the saver's credit, the child tax credit, education credits, and the net investment income tax threshold. A lower AGI can unlock or increase several of these benefits.
