When families apply for federal student aid, the number that matters most is not the price on a college’s website. It is the Student Aid Index, or SAI. This figure is calculated from the information you report on the federal aid application, and colleges use it to decide how much need-based aid you qualify for. Since it replaced the older Expected Family Contribution, the SAI has changed how many families, especially those with several children in college, are treated. Here is what the SAI measures, how it is calculated, and how to read your aid offer with it in mind.
From EFC to SAI
The FAFSA Simplification Act, passed by Congress in December 2020, rewrote the federal need analysis formula. Starting with the 2024–25 award year, the Expected Family Contribution (EFC) was replaced by the Student Aid Index. The name change was intentional. Many families read “expected contribution” as the amount they would have to pay, which was never accurate. The SAI is an eligibility index, not a bill.
Key changes from the old formula
- Siblings in college no longer divide the result. Under the EFC, a family’s parent contribution was split among the number of children in college at the same time. The SAI formula removed that adjustment, which raised the index for many multi-student families.
- The index can be negative. The SAI can go as low as -1500, allowing aid offices to identify students with the greatest need.
- Small business and family farm assets now count. These were previously excluded and are now included as assets in the formula.
- Child support received is reported as an asset, rather than as untaxed income.
How the SAI is calculated
The SAI comes from a federal formula published each year by the Department of Education. There are different formulas for dependent students, independent students without dependents, and independent students with dependents. At a high level, the formula looks at income, assets, and allowances.
Income
The formula starts with income reported on federal tax returns from the “prior-prior year.” For the 2026–27 award year, that is 2024 income. Most of this data now transfers directly from the IRS when you and any required contributors provide consent on the form. Untaxed income, such as certain retirement contributions, may also be included.
Allowances
The formula subtracts allowances that protect part of the family’s income for basic living costs. These include an income protection allowance based on family size, an allowance for federal and state taxes, and an employment expense allowance for working parents. What remains is called available income.
Assets
Reportable assets include cash, savings and checking balances, investments, real estate other than your primary home, and now small businesses and family farms. Retirement accounts such as 401(k)s and IRAs are not counted, and neither is the equity in your primary residence. Parent assets are assessed at a much lower rate than student assets, which is why where savings are held can matter.
Who must contribute information
For dependent students, a parent who provided the most financial support over the past 12 months is the required parent contributor. This replaced the old rule that looked at which parent the student lived with more. If that parent is married, their spouse also becomes a contributor.
Automatic minimum and maximum Pell eligibility
The new formula also determines Pell Grant eligibility more directly. Students whose families have adjusted gross income below set percentages of the federal poverty guideline, which vary with family size and household structure, can be automatically assigned a minimum SAI of -1500 and qualify for a maximum Pell Grant. That means some students know their Pell eligibility with less uncertainty than under the old system.
How colleges use your SAI
Calculating financial need
Each school calculates your financial need with a simple equation:
Cost of attendance − Student Aid Index − other financial assistance = financial need
Cost of attendance includes tuition and fees, housing and food, books and supplies, transportation, and personal expenses. Because cost of attendance varies so much between schools, the same SAI can produce very different need figures. A student with an SAI of $12,000 may have little need at an in-state public college and significant need at a private university.
What need does and does not guarantee
Having financial need does not mean a school will meet it in full. Some colleges meet 100% of demonstrated need, often with a mix of grants and work-study, while many others leave a gap that families must cover with savings or loans. The share of need a school typically meets is published in its Common Data Set and on federal comparison tools.
Institutional formulas
The SAI controls eligibility for federal aid, but many private colleges also use their own methodology for institutional grants. These schools may ask for additional forms and may count assets the federal formula ignores, such as home equity. As a result, your institutional aid could reflect a different estimate of what your family can pay.
Reading your FAFSA Submission Summary
After you submit the aid application, you receive a FAFSA Submission Summary showing your SAI, your estimated Pell Grant eligibility, and the information you reported. Review it carefully:
- Check that income figures transferred from the IRS look right.
- Confirm asset values were entered accurately and that retirement accounts and your home were left out.
- Verify the colleges listed are the ones you want to receive your information.
- Make corrections promptly if anything is wrong, because schools use the most recent processed data.
When your situation has changed
Because the SAI relies on tax information from two years earlier, it may not reflect a recent job loss, divorce, death in the family, or large medical bills. In those cases, contact each college’s financial aid office and ask about professional judgment. Federal law allows aid administrators to adjust data elements on a case-by-case basis when there are documented special circumstances. Be ready to provide paperwork such as termination letters, unemployment benefit statements, or medical bills.
Ways families can plan ahead
- Know which assets count. Money in retirement accounts is not reported, while money in regular savings is.
- Understand student versus parent assets. Assets in a student’s name are assessed more heavily than parent assets.
- Time income events. Large capital gains or retirement withdrawals in the base year raise income used in the formula.
- Use the Federal Student Aid estimator. The official estimator on StudentAid.gov provides an approximate SAI before you apply.
- Apply every year. Your SAI is recalculated annually, and your aid can change as your circumstances do.

Frequently Asked Questions
Is the Student Aid Index the amount my family must pay?
No. The SAI is an index used to determine eligibility for need-based aid. Your actual out-of-pocket cost depends on each school’s cost of attendance and the aid it offers.
Why is my SAI negative?
A negative SAI, down to -1500, indicates very high financial need. It typically results from low income relative to family size and helps schools identify students who may need more than tuition assistance.
Does having two children in college lower the SAI?
Not under the current federal formula. The old EFC divided the parent contribution among siblings in college, but the SAI does not. Some colleges still consider siblings when awarding their own institutional aid.
Do retirement savings affect my SAI?
Balances in qualified retirement accounts such as 401(k)s and IRAs are not reported as assets, so they do not increase your SAI. However, voluntary contributions made during the base year may be counted as untaxed income.
Can I ask a college to recalculate my aid?
Yes. If your financial situation has changed since the tax year used, you can ask the school’s financial aid office for a professional judgment review and provide documentation of the change.
