Your family's financial situation is the foundation of your financial aid package. When you file the FAFSA, the federal formula calculates a number that colleges use to determine how much aid you qualify for. That number is called the Student Aid Index, or SAI. For the 2026-27 school year, the SAI formula remains the same, but major federal policy changes under the One Big Beautiful Bill Act (OBBBA) are reshaping how student loans and repayment work alongside your aid package.
If you're confused about SAI, you're not alone. This guide breaks down what SAI is, how it's calculated, and what the latest 2026-27 changes mean for your family's college plan.
What Is the Student Aid Index (SAI)?
The Student Aid Index (SAI) is a number that appears on your FAFSA results. It tells your college's financial aid office one thing: how much federal need-based aid you're eligible for.
Here's what's important: the SAI is not a dollar amount your family is expected to pay. And it's not a prediction of your total aid. It's simply an eligibility index--a number the college uses alongside other information to decide your aid package.
The SAI replaced the Expected Family Contribution (EFC) starting with the 2024-25 school year. Congress changed the formula in December 2020 as part of the FAFSA simplification effort, with the goal of making the process clearer and more equitable.
How SAI Differs from the Old EFC
The shift from EFC to SAI came with some major changes to how the formula works. Understanding these differences can help you make sense of your results.
SAI Can Be Negative
The biggest change: your SAI can be a negative number, down to -$1,500. The old EFC could never be negative--the lowest it could go was zero.
Why does this matter? A negative SAI means your family qualifies for the maximum federal aid available. For example, if your SAI is -$500, you're eligible for the full Pell Grant. This change helps identify students with the greatest financial need, and the U.S. Department of Education estimated that about 10% more students qualified for a Pell Grant under the new formula.
Fewer Adjustments for Family Size
Under the old EFC formula, if you had siblings in college at the same time, your expected family contribution was divided among them--a "sibling discount." That's gone now. Your SAI is calculated the same way regardless of how many siblings are in college. However, the formula does still consider your total family size when calculating how much income and assets your family is expected to use for college.
The Formula Is Simpler
The EFC formula included many adjustments and special rules. The SAI formula cut those down significantly. Most of the income items in the formula now come straight from tax returns, eliminating guesswork and self-reporting. Items that were counted in the old EFC but aren't on a tax return--like untaxed income from certain sources--are no longer included. This simplification makes the process more transparent and harder to game.
What Goes Into Your SAI?
The SAI calculation pulls from three main sources: parent income, parent assets, and student income and assets. Here's how it breaks down:
Parent Income
Your parents report their adjusted gross income and other income-related information from their tax returns. The formula then allows for certain deductions--taxes paid, Social Security, basic living expenses--to account for what they actually need to live on. Whatever income remains after those allowances is considered available for college expenses.
Larger families get bigger allowances. A four-person household is allowed more living-expense deductions than a two-person household, so a family with more dependents can earn more before they're expected to contribute financially.
Parent and Student Assets
Your parents' assets include cash, savings, checking accounts, investments, and the net value of any business or farm (but not the primary home or retirement accounts). The formula converts parent assets into a contribution at about a 5.64% rate (roughly $56 per $1,000 of assets).
Your own assets--including money you've saved, investments in your name, and any 529 plans or Coverdell accounts--are treated more harshly. Student assets are assessed at 20%, meaning $5,000 in student savings adds $1,000 to your SAI.
Student Income
Any income you earn or receive is part of the calculation. The formula allows a modest student income protection allowance (around $6,660 for 2026-27), so the first chunk of your earnings doesn't count. After that, income is assessed at roughly 50%.
SAI and Pell Grant Eligibility
Your SAI directly affects your eligibility for federal Pell Grants, the largest source of federal grant aid. Here's how the math works:
The maximum Pell Grant for 2026-27 is $7,395. To find your Pell eligibility, your school subtracts your SAI from that maximum. If your SAI is $0 or negative (down to -$1,500), you get the full $7,395 (rounded to the nearest $5). If your SAI is $1,000, your Pell award would be roughly $6,395.
The formula also factors in family size and federal poverty levels. Colleges use a standard formula to calculate what's called your "Cost of Attendance" (tuition, fees, books, living expenses), and then they subtract your SAI to determine your financial need. That need drives your aid package.
How SAI Affects Other Types of Financial Aid
Pell Grants aren't the only aid SAI influences:
- Institutional grants. Most colleges use SAI as the starting point for awarding their own grant money. Lower SAI generally means larger institutional grants.
- Federal work-study. If you're eligible for work-study, your SAI and cost of attendance determine your work-study award.
- Subsidized loans. Your SAI determines whether you qualify for subsidized (interest-paid-by-the-government) vs. unsubsidized federal student loans.
- Merit aid. Some colleges also consider SAI when awarding merit scholarships, though this varies by school.
What Changed for 2026-27: The One Big Beautiful Bill Act
The One Big Beautiful Bill Act (OBBBA), signed in 2025 and taking effect July 1, 2026, brings major changes to federal student loans. While the SAI formula itself stays the same, the aid landscape around it has shifted. Here's what you need to know:
Parent PLUS Loan Caps
Starting with the 2026-27 school year, Parent PLUS loans are capped at $20,000 per year and $65,000 over a student's lifetime. Before this change, parents could borrow up to the full cost of attendance. This cap means families with a high SAI who relied on PLUS loans to fill the gap may need to plan differently. If your SAI is high and your school is expensive, explore other funding sources early.
Grad PLUS Loans Eliminated for New Borrowers
Graduate PLUS loans are no longer available to new borrowers starting July 1, 2026. Current borrowers can continue using existing loans, but new grad students will need to rely on Direct Unsubsidized Loans, private loans, or other funding. This doesn't directly affect undergrad SAI, but families planning for graduate school should factor it in.
Less-Than-Full-Time Enrollment
If you're enrolled less than full time, your federal loan amounts are now prorated. This means half-time students receive proportionally less in loan eligibility. Your SAI stays the same, but the aid you can receive adjusts based on enrollment intensity.
Federal Loan Interest Rates for 2025-26
Current federal loan interest rates (set annually) are:
- Undergraduate Direct Loans: 6.39%
- Graduate Direct Loans: 7.94%
- PLUS Loans (Parent and Grad): 8.94%
These rates apply to loans first disbursed between July 1, 2025, and June 30, 2026. New rates for 2026-27 will be announced in spring 2026.
Changes to Loan Repayment Plans
The repayment landscape has also changed significantly for 2026-27:
SAVE Plan Terminated, RAP Launching
The SAVE (Saving on a Valuable Education) repayment plan has been struck down in court and is no longer available. In its place, the Repayment Assistance Plan (RAP) launches July 1, 2026. RAP sets monthly payments at 1% to 10% of your income, with repayment terms up to 30 years.
Other Income-Driven Plans Still Available
The following income-driven repayment plans remain available:
- IBR (Income-Based Repayment)
- PAYE (Pay As You Earn)
- ICR (Income-Contingent Repayment)
If you're borrowing federal loans, understanding these repayment options is just as important as understanding your SAI. Your SAI determines how much aid you get; your repayment plan determines how manageable your loans are after graduation.
What You Can Control vs. What You Can't
If you're worried about a high SAI, it's worth understanding what you can actually influence.
You can't control:
- Your parents' income (at least not in the short term)
- Your family size
- Your age or grade level
- Previous tax decisions
You can control:
- Reducing liquid assets before filing the FAFSA (paying down debt, using savings strategically)
- Timing of income (if self-employed or freelance)
- Claiming dependent students on the FAFSA
- Which parent claims the student on taxes (if applicable)
Many families look for ways to lower their SAI, from strategic asset timing to shifting income into retirement accounts. Some strategies are legitimate; others cross ethical lines. Talk to a NASFAA-certified financial aid advisor if you're considering any major financial moves before filing the FAFSA.
Common SAI Surprises and Roadblocks to Watch
Students and families often run into unexpected issues with SAI. Here are the biggest ones:
Surprise 1: Assets Count More Than You'd Think
A parent with $50,000 in savings sees about $2,800 added to the SAI. Many families are shocked by how much liquid assets affect their aid eligibility. If you have assets, consider whether paying down debt or making repairs before filing the FAFSA makes sense for your situation.
Surprise 2: Your SAI Might Go Up If You Get a Raise
If a parent gets a raise mid-year, the FAFSA captures that in adjusted gross income. Your family might suddenly qualify for less aid even though the raise is supposed to improve your situation.
Surprise 3: Divorced Parent Rules Changed
Starting with the 2024-25 FAFSA, the "custodial parent" is now determined by who provides the most financial support--not who the student lives with. This is a major shift. If both parents provide roughly equal support, the parent with higher income files the FAFSA. Only the custodial parent's (and their spouse's, if applicable) information is reported; the other parent's details don't count.
This change means some families will see their SAI drop significantly if the lower-earning parent now qualifies as custodial.
Surprise 4: Child Support Is Counted Differently
Under the new formula, child support received counts as an asset, not income. For some families, this means lower SAI; for others, it depends on whether the asset limit affects them.
Surprise 5: PLUS Loan Caps May Change Your Plan
With the new $20,000 annual cap on Parent PLUS loans, families who counted on borrowing more may face a gap. If your SAI is high and your school's cost of attendance exceeds what grants, scholarships, and capped loans cover, you'll need to explore other options--such as 529 savings, private loans, or choosing a more affordable school.

Divorced or Separated Parents: The New Rules
If your parents are divorced, separated, or never married, here's what you need to know about the 2026-27 FAFSA:
Which parent files?
The parent who provided the most financial support in the previous 12 months is the "custodial parent" and files the FAFSA. Financial support includes tuition, school supplies, food, healthcare, clothing, transportation, and anything else you actually needed.
If they split support 50-50, the parent with the higher income is responsible for filing.
What if they live together?
If your divorced parents live under the same roof, they're treated as married for FAFSA purposes. Both parents' income and assets are included, and both are counted in household size.
Stepparents?
If your custodial parent is remarried (and the stepparent was married to your parent on the date the FAFSA was submitted), the stepparent's income and assets must be reported too.
When to File: FAFSA Timeline for 2026-27
The 2026-27 FAFSA opened on September 24, 2025, after a planned October 1 launch was moved up. The federal deadline is June 30, 2027. However, many states and colleges have earlier deadlines--sometimes in February or March.
Filing early gives you the best shot at institutional aid. Colleges award grants on a first-come, first-served basis, so submitting the FAFSA as soon as possible is always smarter than waiting.
The Bottom Line
The SAI is a fundamental piece of your financial aid eligibility. It's not your family's "expected contribution," and it's not a judgment of your family's finances. It's simply a number that helps colleges determine how much need-based aid you qualify for.
The SAI formula is more transparent and generous to lower-income families than the old EFC. For 2026-27, the formula itself hasn't changed, but the One Big Beautiful Bill Act has reshaped the borrowing landscape around it--with Parent PLUS loan caps, the end of Grad PLUS loans for new borrowers, and a new repayment plan (RAP) replacing SAVE.
Understanding what goes into your SAI--and how the new loan rules affect your total college cost--helps you make informed decisions about college affordability. Your SAI is calculated the same way by every college, but what colleges do with that number varies. One school might use it to award more institutional aid; another might focus on loans. That's why it's worth comparing aid packages carefully and asking questions when something doesn't add up.
