The Student Aid Index, or SAI, is the number the FAFSA produces to show how much financial need a student has. It ranges from −1,500 to 999,999, and the lower it is, the more need-based aid a student can qualify for. It is not a bill, not the amount a family must pay and not an aid offer. This guide explains what the SAI means, what a negative or low SAI tells you, why your first SAI is called an estimate, and how to find and estimate yours.
What is the Student Aid Index?
Federal Student Aid defines the SAI as “a formula-based index number ranging from −1500 to 999999” that helps a college decide how much financial support a student may need. It also says the SAI is not a dollar amount of aid, not what a family is expected to provide and not a final aid offer.
The SAI replaced the Expected Family Contribution, or EFC, starting with the 2024–25 school year under the FAFSA Simplification Act. Three changes came with it: the SAI can be negative, the number of family members in college no longer counts, and the old Simplified Needs Test and automatic-zero rules ended.
How the SAI is calculated
The formula adds up the financial resources of the student and parents (or spouse), then subtracts what the family needs for normal living expenses, Federal Student Aid explains. Part of what is left may be counted toward college. The inputs are income, assets and family size, and most of the income figures come straight from the IRS once each contributor gives consent.
There are three versions of the formula, according to Federal Student Aid’s 2027–28 SAI and Pell Grant Eligibility Guide: one for dependent students, one for independent students without dependents other than a spouse, and one for independent students with dependents. Every applicant gets an SAI, but not every applicant qualifies for a Pell Grant.
Some assets are left out. Starting in 2026–27, the FAFSA does not count the net worth of a family-owned business with 100 or fewer full-time employees, a farm the family lives on, or a family-owned commercial fishing business, Federal Student Aid announced. The home a family lives in and retirement accounts are not reported as assets either.
How colleges use your SAI
Colleges subtract the SAI from the cost of attendance to find a student’s financial need, as shown on Federal Student Aid’s How Financial Aid Is Calculated page:
| Cost of attendance | minus Student Aid Index | equals Financial need |
|---|---|---|
| $16,000 | 12,000 | $4,000 |
Need sets the limit for need-based aid: the Pell Grant, the Federal Supplemental Educational Opportunity Grant, Federal Work-Study and Direct Subsidized Loans. Unsubsidized loans and PLUS loans do not depend on the SAI. Colleges and private scholarship programs may also use their own formulas for their own aid, so the number on a college’s aid offer can differ from your federal SAI.
What a negative SAI means
A negative SAI means higher financial need. The lowest possible SAI is −1,500, and Federal Student Aid says a student with an SAI of −1,500 qualifies for a maximum Pell Grant, as long as they have not used up their lifetime Pell eligibility and meet the other requirements. Students whose parents (or who themselves, if independent) did not file a federal tax return are assigned an SAI of −1,500 automatically. For awarding, colleges treat any negative SAI as zero.
What counts as a low SAI?
There is no official cut-off for a “low” SAI. The official rule is simpler: a student with an SAI of zero or below is eligible for a maximum Pell Grant. Under the 2027–28 guide, students also qualify for the maximum Pell Grant if their family’s income is at or below set shares of the federal poverty guideline: 225 percent for a single parent, or 175 percent otherwise.
At the other end, a 2025 law sets an upper limit. A student whose SAI is at least twice the maximum Pell Grant cannot receive a Pell Grant, except under a special rule for children of certain deceased service members and public safety officers. For 2026–27, the maximum Pell Grant is $7,395 and the limit is an SAI of 14,790. The 2027–28 award amounts had not been published when this article was written.
Between those points, the Pell Grant is roughly the maximum award minus the SAI, with a minimum award of $740 in 2026–27.
Estimated SAI and official SAI
Many families see two SAIs. Federal Student Aid says you will see an estimated SAI on the FAFSA confirmation page right after you submit, and an official SAI on your FAFSA Submission Summary once the form is processed. Most forms are processed right away; some take one to three days. The SAI can also change later if you or a college corrects the form.
To find your official SAI, log in to StudentAid.gov, select your processed FAFSA, choose “View FAFSA Submission Summary” and open the “Eligibility Overview” tab. Check the answers on the summary first: Federal Student Aid notes that an incorrect answer can cause errors in your SAI, and you can fix many of them with a correction.
Is there a Student Aid Index chart?
No. Federal Student Aid does not publish a chart that converts income into an SAI, because the result depends on family size, assets, state and other answers. The official tool for families is the Federal Student Aid Estimator, which approximates your SAI and Pell Grant before you file. The full formula tables are in the SAI and Pell Grant Eligibility Guide, written for financial aid offices.
What families and counselors should know
- The SAI is not what you will pay. Look at the net cost on each college’s aid offer.
- File even if you expect a high SAI. Unsubsidized loans and many college scholarships still require a FAFSA.
- Check the Submission Summary before the deadlines. A wrong answer can change the SAI; corrections for 2027–28 are accepted until Sept. 12, 2028.
- Ask about special circumstances. If income has dropped since 2025, the year the 2027–28 FAFSA uses, the financial aid office can review it.

Frequently asked questions
What does SAI mean on the FAFSA? Student Aid Index: a number from −1,500 to 999,999 that colleges use to measure financial need. Lower means more need.
Is a negative Student Aid Index good? It means high financial need. An SAI of zero or below qualifies a student for a maximum Pell Grant if they meet the other requirements.
Is the Student Aid Index the same as the EFC? It replaced the Expected Family Contribution in 2024–25, with a different formula. Unlike the EFC, it can be negative and does not count siblings in college.
Why did my SAI change? The first SAI is an estimate. The official SAI comes after processing, and it can change after a correction.
Where can I see a Student Aid Index chart? There is no official chart. Use the Federal Student Aid Estimator.
