If you have filed the FAFSA recently, you have seen a number called the SAI, short for Student Aid Index. It replaced the old Expected Family Contribution (EFC), and it is the single most important number in your financial aid file. Colleges use it to decide how much need-based aid your student qualifies for. This guide explains what the SAI is, how it is calculated for 2026-27, and what your number actually means for your college bill.
Want your number now? You can estimate your SAI in about five minutes with the CollegeLens SAI Calculator, which uses the exact 2026-27 federal formula and tables.
The Short Answer
The SAI is an eligibility index, not a price tag. After you submit the FAFSA, the federal formula turns your family's income, assets, and household size into a single number. That number can range from -1500 to well into the six figures.
Colleges then use it in one simple equation:
- Cost of attendance (COA) minus SAI = your demonstrated financial need
A school with a $60,000 cost of attendance and a student with a $10,000 SAI sees $50,000 of demonstrated need. How much of that need a college actually covers varies a lot by school, which is why the same SAI can produce very different offers. Our guide to demonstrated need and gapping explains how colleges decide how much to meet.
What Goes Into Your SAI
The federal formula looks at four main things:
- Parent income. Adjusted gross income from your federal tax return, pulled in automatically from the IRS, plus certain untaxed income. This is the biggest driver for most families.
- Parent assets. Cash, savings, brokerage accounts, and 529 plans, assessed at a maximum rate of about 5.64%. Retirement accounts and your primary home do not count. Starting with the 2026-27 FAFSA, small family businesses and family farms are also excluded.
- Student income and assets. Money in the student's name counts more heavily. Student assets are assessed at 20%, which is why savings in a parent's name usually helps your aid picture.
- Household size. A larger household earns a bigger income protection allowance, which shields more of your income from the formula.
One thing that no longer helps: having two kids in college at the same time. The old EFC formula split your number between siblings. The SAI formula does not. If that hits your family, read what to do when two kids are in college at once.
What Your SAI Number Means
Here is how to read your number for the 2026-27 award year:
- Negative SAI (down to -1500). The formula flags your family as having the highest need. You qualify for the maximum Pell Grant of $7,395 and should receive the strongest need-based packages.
- SAI of 0 to roughly 1,000. You still qualify for most or all of the maximum Pell Grant, plus state grants and institutional need-based aid.
- SAI between about 1,000 and 14,790. You may receive a partial Pell Grant on a sliding scale, along with need-based aid at schools whose cost of attendance exceeds your SAI.
- SAI of 14,790 or higher. For 2026-27, this is the cutoff where Pell Grant eligibility ends. You can still receive need-based institutional aid at expensive schools, merit scholarships anywhere, and federal student loans at any SAI.
Two important reminders. First, the SAI is not what you will pay. Many families pay more than their SAI at schools that do not meet full need, and some pay less at generous ones. Second, a high SAI does not mean you should skip the FAFSA. Federal loans and many merit awards require it regardless of income. Our guide to income limits for financial aid covers this in detail.
SAI vs. the Old EFC: What Changed
If you had a student in college before 2024, the SAI works differently from the EFC you remember:
- It can go negative. The EFC bottomed out at zero. A negative SAI helps colleges identify the students with the deepest need.
- No sibling division. The number-in-college adjustment is gone, which raised the effective number for many multi-child families.
- Simpler income protection. The formula uses a cleaner income protection allowance and pulls tax data directly from the IRS.
- Pell eligibility is more predictable. Pell awards are now tied to clear SAI thresholds and family size relative to the poverty line, so you can estimate your grant before award letters arrive. See our guide to Pell Grant eligibility.

How to Estimate Your SAI Before You File
You do not have to wait for the FAFSA to learn your number. The CollegeLens SAI estimator walks through the same questions the FAFSA asks and shows your likely SAI in about two minutes, with no Social Security number required.
Knowing your SAI early helps you:
- Build a college list around schools where your demonstrated need is likely to be met
- Estimate your Pell Grant and state grant eligibility before you apply
- Spot problems, like assets in the wrong name, while there is still time to adjust
If your number comes back higher than expected, there are legal ways to lower it before you file. Our guide to reducing your SAI before the FAFSA covers the timing and asset strategies that actually work.
What to Do With Your SAI
Once you know your number, put it to work:
- Run each school's numbers. Subtract your SAI from each college's cost of attendance to see your demonstrated need at that school.
- Check each school's aid track record. A school that meets 100% of need treats a $50,000 need very differently than one that meets 60%.
- File the FAFSA early. State grant money at many states is first come, first served.
- Compare real offers, not sticker prices. When award letters arrive, the school with the higher sticker price may cost you less.
If you want this done for you, create your free CollegeLens plan. It combines your SAI with each school's actual aid patterns to show your likely out-of-pocket cost side by side, so you can see which schools truly fit your budget.
The SAI Rules That Catch Families Off Guard
A few parts of the formula regularly surprise families the first time they file. Knowing them before you file beats discovering them on the confirmation screen.
Divorced or separated parents: support decides who files, not the roof. The parent who provided the most financial support in the previous 12 months files the FAFSA, even if the student lives with the other parent. Support means tuition, food, healthcare, clothing, and the rest of what the student actually needed. If support is roughly equal, the higher income parent files. Only that parent's household is reported, and if they have remarried, the stepparent's income and assets count too. Divorced parents who still live under the same roof are treated as married. Some families see their SAI drop sharply when the lower earning parent is the one who files, which makes this worth working out before filing rather than after.
Child support received counts as an asset, not income. The current formula treats child support received as an asset rather than income. For many families that lowers the SAI compared with the old treatment, though the effect depends on your overall asset picture.
Money in the student's name is assessed at 20 percent. Student owned savings and investments are counted far more heavily than parent assets. Five thousand dollars in a student's savings account adds about a thousand dollars to the SAI, while the same money held by a parent adds far less. Where savings sit matters.
Your income arrives on a two year delay. The FAFSA uses tax information from two years before the aid year, so a raise, a bonus, or a layoff shows up in your SAI two years later. If your family's income has dropped since the tax year the form uses, you do not have to live with the stale number: ask the financial aid office about a professional judgment review.
Quick Answers About the SAI
- Is the SAI what I will pay for college? No. It is an eligibility index. Your actual price depends on each school's cost and how much of your need it meets.
- What is the lowest and highest the SAI can be? It can go as low as -1500. There is no upper cap; high-income families can see six-figure SAIs.
- Does a 529 plan raise my SAI? A parent-owned 529 counts as a parent asset, assessed at no more than 5.64% of its value. It is one of the most aid-friendly ways to save.
- Do I need a new SAI every year? Yes. You refile the FAFSA annually, and your SAI can change with your income, assets, and household size.
- Can my SAI be adjusted? Yes. If your family's finances changed since the tax year the FAFSA uses, a financial aid office can revise your numbers through professional judgment.
The Bottom Line
The SAI is the number that determines your need-based aid. It is calculated from your income, assets, and household size, it can dip as low as -1500, and for 2026-27 it determines Pell Grants up to $7,395, with eligibility ending at an SAI of 14,790. It is not the price you will pay, but it shapes every need-based dollar on your award letters. Estimate it early, understand what drives it, and use it to build a smarter college list.
