So what is an SAI?footnote 1
Your Student Aid Index (SAI) is an index number that colleges use to determine how much financial aid you're eligible to receive. Your SAI is calculated according to a formula established by law and the information from your Free Application for Federal Student Aid (FAFSA®).
The SAI factors in your family's taxed and untaxed income, assets, and benefits (such as unemployment or Social Security). Your household size is also considered.
Note: Your SAI isn't the amount of money your family will have to pay for college and it isn't the amount of federal student aid you'll receive.
