What this tool does

Works out AGI the way Form 1040 does: add up wages, business income, capital gains and other income, then subtract the adjustments that sit above the line — deductible retirement contributions, HSA contributions, half of self-employment tax, student-loan interest (capped at $2,500) and other adjustments. AGI then drives your standard/itemized decision, most credits and your state starting point.

How to use the AGI Calculator

  1. Enter your figures in the fields above.
  2. Check the filing status, state and pay-frequency selections — they change the tables used.
  3. Read the headline result first, then the breakdown: it shows exactly which tax or amount produced each line.
  4. Change any input to compare scenarios; the result updates with the same dated tables shown on this page.

Formula

AGI = total income − (retirement + HSA + ½ SE tax + min(student interest, $2,500) + other adjustments)
adjustments
Schedule 1 deductions — they reduce AGI whether or not you itemize

Worked example

$97,000 of total income minus $8,000 of adjustments gives an AGI of $89,000.

Frequently asked questions

Your total income from all sources minus a specific list of adjustments (Schedule 1). It is the last line of page 1 of Form 1040 and the number most tax limits key off.

No. Taxable income is AGI minus the standard or itemized deduction (and the qualified business income deduction). AGI comes first.

MAGI is AGI with certain items added back, and the add-backs depend on the provision — student-loan interest for that deduction, foreign earned income and some others for IRA and credit tests.

Line 11 of last year's Form 1040. The IRS also uses it as an identity check when you e-file.

Yes — traditional 401(k) deferrals are excluded from wages, and deductible traditional IRA contributions are an above-the-line adjustment. Roth contributions do not lower AGI.
