The Student Aid Index, or SAI, is a measure that colleges use to determine a student's ability to pay for school. It also determines the amount of financial aid students can receive.
Students receive an SAI after submitting the Free Application for Federal Student Aid (FAFSA).
How is the Student Aid Index calculated?
The index equals the sum of you and your parents’ (or spouse’s) total financial resources, minus annual living expenses.
The information you input on the FAFSA about you and your family’s financial profile determines your SAI. In most cases, the FAFSA automatically pulls this information from your tax return.
Once you submit the FAFSA and the Education Department processes the form, you’ll receive your FAFSA Submission Summary, which details the information you included on the application and your SAI.
Students must submit the FAFSA each year they are in school to unlock federal student loans, Pell Grants, work-study and even some private scholarships.

Fixed APR
2.89-17.49%
Lowest rates shown include the auto debit discount. Advertised APRs for undergraduate students assume a $10,000 loan to a student who attends school for 4 years and has no prior Sallie Mae-serviced loans. Interest rates for variable rate loans may increase or decrease over the life of the loan based on changes to the 30-day Average Secured Overnight Financing Rate (SOFR) rounded up to the nearest one-eighth of one percent. Advertised variable rates are the starting range of rates and may vary outside of that range over the life of the loan. Interest is charged starting when funds are sent to the school. With the Fixed and Deferred Repayment Options, the interest rate is higher than with the Interest Repayment Option and Unpaid Interest is added to the loan’s Current Principal at the end of the grace/separation period. To receive a 0.25 percentage point interest rate discount, the borrower or cosigner must enroll in auto debit through Sallie Mae. The discount applies only during active repayment for as long as the Current Amount Due or Designated Amount is successfully withdrawn from the authorized bank account each month. It may be suspended during forbearance or deferment. Advertised APRs are valid as of 8/11/2025. Loan amounts: For applications submitted directly to Sallie Mae, loan amount cannot exceed the cost of attendance less financial aid received, as certified by the school. Applications submitted to Sallie Mae through a partner website will be subject to a lower maximum loan request amount. Miscellaneous personal expenses (such as a laptop) may be included in the cost of attendance for students enrolled at least half-time. Examples of typical costs for a $10,000 Smart Option Student Loan with the most common fixed rate, fixed repayment option, 6-month separation period, and two disbursements: For a borrower with no prior loans and a 4-year in-school period, it works out to a 10.28% fixed APR, 51 payments of $25.00, 119 payments of $182.67 and one payment of $121.71, for a Total Loan Cost of $23,134.44. For a borrower with $20,000 in prior loans and a 2-year in-school period, it works out to a 10.78% fixed APR, 27 payments of $25.00, 179 payments of $132.53 and one payment of $40.35 for a total loan cost of $24,438.22. Loans that are subject to a $50 minimum principal and interest payment amount may receive a loan term that is less than 10 years. A variable APR may increase over the life of the loan. A fixed APR will not.

SAI is used as part of the equation for financial need. Financial aid officers subtract your SAI and other financial assistance from the cost of attendance. Your cost of attendance at a certain school includes tuition, fees and room and board.
The financial aid eligibility equation essentially looks like this: Cost of attendance – SAI = financial need
Your SAI can range from -1,500 to 999,999. A lower SAI indicates a higher level of financial need and makes it more likely that you'll qualify for financial aid, like the need-based Pell Grant.
For example, if your cost of attendance is $30,000 and your SAI is -$1,500, your estimated financial need would be $31,500.
Colleges aren’t required to meet 100% of your financial need, though some do. In addition to need-based aid like grants or scholarships, your financial aid package may also include federal student loans, which you repay in the future. Some types of aid, such as work-study, might also be limited at your school.
