AGI Formula Explained
Here’s the basic formula used by the AGI Income Calculator:
AGI = Gross Income - Allowable Adjustments
Where:
- Gross Income = Wages + Business Income + Capital Gains + Dividends + Rental Income + Other Earnings
- Allowable Adjustments = Student Loan Interest + IRA Contributions + HSA Contributions + Tuition + Other Deductibles
Example of AGI Calculation
Scenario:
John is a freelance graphic designer who earns $80,000 annually. He contributed $3,000 to an IRA, paid $1,500 in student loan interest, and added $2,000 to a Health Savings Account (HSA).
Step-by-step calculation:
- Gross Income = $80,000
- Adjustments:
- IRA Contribution = $3,000
- Student Loan Interest = $1,500
- HSA Contribution = $2,000
- Total Adjustments = $6,500
AGI = $80,000 - $6,500 = $73,500
This amount ($73,500) will be the basis for calculating his taxable income and credits.
