The agi calculator works out total adjustments to income, adjusted gross income and grossincome from spousal support / alimony received, alimony paid, pension / annuity / ira distributions, awards / prizes / winnings, business / self-employment, capital gains and losses, educator expenses, health insurance premiums, healthcare savings account (hsa) contributions, interest, dividends, royalties, etc., contributions to retirement / iras, jury duty fees, moving expenses, other deductions, otherincome, real estate/rental income and losses, retirement plan contributions, school tuition, half of self-employment tax, social security benefits, taxable state refunds, student loan interest, unemployment compensation and salary, wages and tips. Enter what you have and the relationship is applied straight away, so you get the answer without working through the algebra yourself.
What Is the AGI Calculator?
The agi calculator takes spousal support / alimony received, alimony paid, pension / annuity / ira distributions, awards / prizes / winnings, business / self-employment, capital gains and losses, educator expenses, health insurance premiums, healthcare savings account (hsa) contributions, interest, dividends, royalties, etc., contributions to retirement / iras, jury duty fees, moving expenses, other deductions, otherincome, real estate/rental income and losses, retirement plan contributions, school tuition, half of self-employment tax, social security benefits, taxable state refunds, student loan interest, unemployment compensation and salary, wages and tips and turns them into total adjustments to income, adjusted gross income and grossincome.
It is the kind of calculation you would otherwise do on the back of an envelope: mechanical, repeatable and easy to get subtly wrong without noticing.
How the AGI Figure Is Built
Each result is calculated from the ones before it, so the working is fully visible. That matters when the answer is going to be quoted to somebody else and you need to be able to explain where it came from.
The figures are exactly as good as the assumptions underneath them. Check the rates, the periods and the tax treatment before you rely on the result.
Reading the Result Sensibly
A small change in an input can move the result by much more than you would expect, particularly where the calculation divides by one of the figures you supplied. That is worth understanding before you rely on a figure.
For anything that will be committed to, write the inputs down beside the result. A number you can reproduce is worth far more than one you cannot explain.
A Worked Example
Working through an example, with spousal support / alimony received set to 10, alimony paid set to 5, pension / annuity / ira distributions set to 2, the calculator returns grossincome of 546, and total adjustments to income of 156, and adjusted gross income of 390. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out total adjustments to income?
Enter spousal support / alimony received, alimony paid, pension / annuity / ira distributions, awards / prizes / winnings, business / self-employment, capital gains and losses, educator expenses, health insurance premiums, healthcare savings account (hsa) contributions, interest, dividends, royalties, etc., contributions to retirement / iras, jury duty fees, moving expenses, other deductions, otherincome, real estate/rental income and losses, retirement plan contributions, school tuition, half of self-employment tax, social security benefits, taxable state refunds, student loan interest, unemployment compensation and salary, wages and tips. The calculator then works through the relationship and reports total adjustments to income, adjusted gross income and grossincome.
What does the agi actually calculate?
It takes spousal support / alimony received, alimony paid, pension / annuity / ira distributions, awards / prizes / winnings, business / self-employment, capital gains and losses, educator expenses, health insurance premiums, healthcare savings account (hsa) contributions, interest, dividends, royalties, etc., contributions to retirement / iras, jury duty fees, moving expenses, other deductions, otherincome, real estate/rental income and losses, retirement plan contributions, school tuition, half of self-employment tax, social security benefits, taxable state refunds, student loan interest, unemployment compensation and salary, wages and tips and converts them into total adjustments to income, adjusted gross income and grossincome using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter spousal support / alimony received?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Why does a small change in one value move the answer so much?
That happens when an output depends on a ratio, because dividing by a small number magnifies any change in it. Check the units first, then check whether the value you entered is in the range the relationship was designed for.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
