SAI is the number the FAFSA uses to calculate how much aid you might receive
SAI stands for Student Aid Index. It is a number calculated from the information you report on your FAFSA form. The federal government uses your SAI to determine how much federal student aid you may be offered, including grants, loans, and work-study.
The FAFSA collects details about your income, assets, family size, and number of family members in college. A federal formula processes these details and produces your SAI. A lower SAI means you may receive more aid; a higher SAI means you may receive less. Schools also use your SAI to decide how much of their own aid to offer you.
SAI replaced an older term called EFC (Expected Family Contribution) in 2023. The calculation method changed at the same time, so your SAI number may look different from what you saw in previous years, even if your family's finances have not changed.
Key Takeaways
- SAI is calculated directly from your FAFSA answers about income, assets, family size, and how many family members are in college.
- A lower SAI results in a higher aid offer; a higher SAI results in a lower aid offer.
- Your school uses your SAI to build your financial aid package, which may include federal grants, loans, and work-study.
- SAI is not the same as how much you will actually pay — it is one piece of information your school uses to decide aid.
How the FAFSA calculates your SAI
The FAFSA asks for your income from the prior tax year, your savings and investments, your parents' income and assets (if you are a dependent student), and information about your family size and how many people in your family are currently in college.
The federal formula weighs these pieces differently. Income is counted more heavily than assets. Parent income and assets are counted differently than student income and assets. The number of family members in college reduces the amount counted against you, because the aid formula assumes the family's resources are spread across multiple students.
The result is a single number: your SAI. This number is reported on your Student Aid Report (SAR), which you receive after you submit your FAFSA. You can also view your SAI in your FAFSA account online.
What your SAI number actually means for aid
Your SAI is not a dollar amount you owe or a prediction of what you will pay. Instead, it is an input into a formula each school uses to build your aid package.
Schools subtract your SAI from their Cost of Attendance (COA) — the total cost to attend that school for one year, including tuition, fees, room, board, and books. The result is your Financial Need. Schools then decide how much of that need to cover with grants, loans, and work-study.
Two students with the same SAI may receive different aid packages from the same school, because schools have different amounts of aid to distribute and different policies about how much to cover. A school with more aid money may cover more of your need; a school with less may cover less.
How SAI changed from the old EFC system
Before 2023, the FAFSA reported a number called EFC (Expected Family Contribution). In 2024, the Department of Education renamed this to SAI and changed how it is calculated.
The new SAI formula counts fewer assets, treats student income differently, and adjusts for family size in a new way. Because of these changes, your SAI in 2024 or later may be lower than your EFC was in previous years, even if your family's finances have not changed. Some students saw their SAI drop significantly; others saw smaller changes.
If you are comparing aid offers across multiple years, remember that a lower SAI does not necessarily mean your family is in a better financial position — it may simply reflect the new calculation method.
Why your SAI matters when comparing schools
Your SAI is the same at every school you apply to, because it comes from your FAFSA answers. But the aid you receive will differ by school, because each school has its own cost of attendance and its own aid budget.
A school with a higher cost of attendance and more aid money may offer you more total aid than a school with a lower cost of attendance and less aid money, even though your SAI is identical. This is why it is important to look at the actual aid package each school sends you, not just your SAI.
When you receive aid offers from multiple schools, compare the net price (cost of attendance minus all aid offered) rather than comparing SAI numbers. Your SAI is just one piece of the picture.
What to do if your SAI seems wrong
If you believe the information on your FAFSA is incorrect, you can make corrections in your FAFSA account. Common errors include wrong income figures, wrong family size, or wrong information about how many family members are in college.
After you make corrections, your SAI will be recalculated. Schools you have already sent your FAFSA to will receive an updated Student Aid Report. If you have already received an aid package from a school, contact that school's financial aid office to let them know your FAFSA has been corrected — they may recalculate your aid based on the new SAI.
If your family's financial situation has changed significantly since you filed your FAFSA (such as a job loss or unexpected expense), contact your school's financial aid office directly. Many schools have a process called Professional Judgment that allows them to adjust your aid based on circumstances the FAFSA does not capture.
Frequently Asked Questions
Is a low SAI good or bad?
A low SAI is good — it means you may receive more aid. A high SAI means you may receive less aid. Think of SAI as a measure of how much aid the government thinks your family can contribute; lower SAI means higher aid.
Can I change my SAI?
You cannot directly change your SAI, but you can correct the information on your FAFSA if it is wrong. If your family's financial situation has changed since you filed, contact your school's financial aid office to discuss whether they can adjust your aid through their Professional Judgment process.
Does SAI determine how much I have to pay?
No. SAI is one input schools use to calculate aid, but it does not determine your actual cost. Your actual cost depends on the school's total cost of attendance and how much aid that school chooses to offer you.
Will my SAI be the same at every school?
Yes. Your SAI comes from your FAFSA and is the same everywhere. But each school will use your SAI differently based on their own cost of attendance and aid budget, so your aid packages will vary by school.
What if I have no income or assets?
You will still have an SAI, but it may be zero or close to zero. A SAI of zero does not mean you receive unlimited aid — it means you have no expected family contribution, and schools will calculate your need based on their full cost of attendance.
