If you've filed the FAFSA recently, you may have seen the term SAI on your Student Aid Report. SAI stands for Student Aid Index — and it's one of the most important numbers in financial aid, even though it's largely invisible to students.

What is it?

The Student Aid Index is a number calculated from your FAFSA that represents how much the federal government expects your family to contribute toward your education costs. A lower SAI generally means more financial need and more potential aid eligibility.

SAI replaced the Expected Family Contribution (EFC) beginning with the 2024–25 FAFSA cycle. The calculation changed meaningfully — notably, families with multiple children in college no longer see an automatic reduction in their index.

What does the number mean?

  • SAI of 0 or negative: highest financial need, likely eligible for maximum Pell Grant
  • SAI of 1–6,000: significant need, likely eligible for some Pell Grant and need-based institutional aid
  • SAI above 6,000: limited need-based eligibility, though merit aid and institutional grants may still apply

SAI vs. what the school offers

Your SAI determines your federal aid eligibility, but what a school actually offers you depends on the school's own institutional aid policy. Schools with large endowments may meet 100% of demonstrated financial need. Schools with limited resources may leave a significant gap even for students with low SAIs.

What you can't control — and what you can

You can't directly change your SAI after filing. But you can:

  • Appeal if your family's financial situation has changed materially
  • Apply to schools known for meeting need generously
  • File FAFSA as early as possible (October 1)
  • Correct any errors in your FAFSA that may have inflated your SAI

Understanding your SAI helps you set realistic expectations about federal and institutional aid before you compare offers.

Frequently Asked Questions

What is the Student Aid Index (SAI)?

The SAI is a number the Department of Education calculates from your FAFSA to determine how much federal aid you are eligible for. It replaced the older Expected Family Contribution (EFC) starting with the 2024-25 FAFSA.

How is SAI calculated?

SAI is calculated from student and parent income, assets, and family size using the federal formula. Unlike EFC, SAI can go as low as negative 1,500 to identify students with the greatest need.

What is a good SAI number?

Lower is better. A negative SAI means you have the highest need and typically qualify for maximum Pell Grant. An SAI of 0 to 7,500 usually qualifies for some Pell.

Does SAI include home equity or retirement accounts?

No. Primary home equity and retirement account balances are excluded from the SAI formula.

How is SAI different from EFC?

SAI can be negative, does not increase with the number of siblings in college, uses updated income protection allowances, and pulls tax data directly from IRS via the FA-DDX. EFC did none of those.
