For thirty years, the Expected Family Contribution (EFC) was the single number that defined every family’s financial-aid eligibility. The 2024 FAFSA rewrite replaced it with the Student Aid Index (SAI) — and while the purpose is the same, the formula behind it is meaningfully different. For some families, the change unlocks new aid. For others — particularly families with multiple children in college simultaneously — it cuts aid significantly. Here’s what changed and how to read the new number.
What happened to the EFC?
Starting with the 2024-25 FAFSA (the first cycle under the FAFSA Simplification Act of 2020), the Expected Family Contribution (EFC) was renamed the Student Aid Index (SAI) and the underlying formula was rewritten. The change took effect with the form that launched in December 2023 and continues through every subsequent cycle.
The EFC was the official term used on the FAFSA from the 1990s through the 2023-24 application cycle. It was the dollar figure that represented what the federal formula calculated the family could “expect” to contribute toward one year of the student’s college cost. Schools then used the EFC to determine eligibility for Pell Grants, subsidized loans, state aid, and institutional need-based aid.
The same number still drives the same downstream decisions — federal aid, state aid, and institutional need-based aid — but the formula that produces the number, and the way schools interpret it, has changed.
Why did the FAFSA replace the EFC with the SAI?
The Department of Education and Congress framed the EFC-to-SAI change around two goals: simplification (the new FAFSA is significantly shorter than the old one) and inclusivity (the new SAI formula expands Pell Grant eligibility for low-income families and removes some of the more confusing aspects of the old EFC calculation).
The FAFSA Simplification Act passed Congress in December 2020 with bipartisan support. Implementation was supposed to begin with the 2023-24 FAFSA but was delayed by a year due to the complexity of rebuilding the federal aid-processing system. The actual launch in December 2023 was famously rocky — the new form had significant bugs, schools received data months late, and the entire 2024-25 aid cycle ran behind schedule. By the 2025-26 and 2026-27 cycles, the system had stabilized, but the changes the law made are now permanent.
The renaming from “Expected Family Contribution” to “Student Aid Index” was also intended to reduce confusion. The old EFC label implied that the calculated number was what the family would actually pay — but in reality, most families paid more than their EFC because most schools didn’t meet 100% of demonstrated financial need. The new SAI label is meant to clarify that the number is an index used for eligibility ranking, not a literal contribution amount.
What stayed the same when the EFC became the SAI?
Despite the formula changes, the SAI plays the same structural role as the EFC did: it is still the federal eligibility number, still feeds state aid and institutional need-based aid, is still calculated from income and assets, and is still subject to Professional Judgment review. The mechanics of how it’s calculated are where the differences live. Specifically:
- It’s still the federal eligibility number. Federal aid programs (Pell Grant, subsidized Direct Loans, Federal Work-Study, Supplemental Educational Opportunity Grant) are calculated from the SAI just like they were from the EFC.
- It still feeds state aid. State grant programs use the SAI as the federal aid eligibility input, often combined with state-specific criteria.
- It still feeds institutional aid at most schools. Need-based grants and scholarships from the school itself are typically calculated against the SAI, either dollar-for-dollar (at full-need-met schools) or proportionally (at most other schools).
- It’s still calculated from income and assets. The two big inputs are still the family’s adjusted gross income (or income equivalent for non-tax-filers) and their reportable assets.
- It’s still subject to Professional Judgment review. A school’s financial aid office can still adjust the data inputs if the family’s circumstances have changed, just like they could with EFC. See the Professional Judgment guide for the appeal process.
If you understood EFC, the SAI’s role is identical.
How is the SAI different from the EFC?
Four significant changes distinguish the SAI formula from the old EFC formula: the SAI can now be negative (down to approximately -$1,500); the “number in college” divisor no longer reduces the parent contribution; family farms and small businesses are now reportable assets; and a new poverty-level pathway awards the maximum Pell Grant automatically to low-income families.
| Old EFC | New SAI (2024-25 and later) | |
|---|---|---|
| Lowest possible value | $0 floor | Negative allowed, down to about -$1,500 |
| Multiple kids in college | Parent contribution divided by number in college | No divisor — full parent contribution applied to each child |
| Family farm / small business (<100 employees) | Excluded from assets | Reportable (with credit for secured debt) |
| Max-Pell shortcut for low income | None | Automatic max Pell below 175% of poverty level (225% two-parent) |
1. Negative SAI is now allowed. The old EFC formula was floored at $0 — the lowest possible EFC was zero, even for families with no income. The new SAI formula allows negative numbers, down to approximately -$1,500. A negative SAI doesn’t mean the school owes the family money — it means the family has demonstrated extra need beyond a zero contribution, which makes them eligible for the maximum Pell Grant plus, at responsive schools, additional institutional aid. For families in deep financial hardship, the negative-SAI tier is a meaningful upgrade over the old “$0 EFC = floor” treatment.
2. “Number in college” no longer divides the parent contribution. This is the single largest change for multi-child families. Under the old EFC formula, the parent contribution was divided by the number of children currently enrolled in college simultaneously. A family with two kids in college had their parent contribution cut in half per child. A family with three had it cut by two-thirds. This divisor was the single biggest reason multi-child families got disproportionate aid increases when more than one student was enrolled.
The new SAI formula eliminates that divisor for the federal calculation. The parent contribution is calculated once and applied in full to each child’s SAI. A family with two kids in college whose old EFC was $10,000 per child (split from $20,000) now sees an SAI of approximately $20,000 per child. The effect is significant — and largely unhelpful for families who counted on the multi-child reduction.
It’s worth noting what the divisor change does not affect:
- Pell tier eligibility (still evaluated per-family with multi-child considerations)
- The auto-zero SAI thresholds (still consider household composition)
- CSS Profile institutional aid (some private schools using the CSS Profile retain a number-in-college divisor for their own institutional methodology)
- State aid programs (rules vary by state)
But the federal SAI itself does not divide. Families with multiple children in college simultaneously should expect noticeably less federal and most institutional aid per child under the new rules than they would have under the old EFC.
3. Family farms and small businesses are now reportable. Under the pre-2024 rules, a family farm where the family lived and worked, and a small business with fewer than 100 employees owned and operated by the family, were both excluded from FAFSA asset reporting. The new rules made both reportable, though the formula gives credit for outstanding debt secured against the asset. For families whose primary wealth is tied up in a family-owned operation, this change increased reportable assets significantly.
4. New poverty-level-based Pell eligibility. The new formula introduces a “minimum Pell” pathway that bypasses the SAI calculation entirely for low-income families. If a dependent student’s parents’ adjusted gross income is below 175% of the federal poverty level for a single parent (or 225% for a two-parent household), the student qualifies for the maximum Pell Grant automatically, regardless of what the SAI formula would otherwise produce. This change was specifically designed to simplify Pell eligibility for low-income families and reduce the number of eligible students who didn’t apply because they didn’t realize they qualified.
Where do you find your SAI?
The SAI appears prominently on your Student Aid Report (SAR) — the post-submission summary available within 1-3 business days at studentaid.gov. It’s labeled “Student Aid Index” and shown as a single dollar figure, which may be negative, zero, or positive up to $999,999.
The SAI is the federal SAI — the number used for federal aid eligibility. Schools that calculate institutional aid using their own methodology (most CSS Profile schools and some private institutions) may produce a different “institutional SAI” or “institutional index” that they use for institutional aid alongside the federal SAI for federal aid.
What does your SAI number mean for aid eligibility?
A rough guide for 2026-27: an SAI between -$1,500 and $0 qualifies for the maximum Pell Grant (currently $7,395/year); from $0 to $7,395, a partial Pell on a sliding scale; from $7,395 to $30,000, no Pell Grant but a subsidized loan is still possible; above $30,000, typically no need-based federal aid.

| SAI range | Pell Grant | Subsidized Direct Loan | Institutional need-based aid |
|---|---|---|---|
| -$1,500 to $0 | Maximum ($7,395/yr) | Maximum eligibility | Maximum at responsive schools |
| $0 to $7,395 | Partial, sliding scale | Eligible | Eligible at most responsive schools |
| $7,395 to $30,000 | None | Possible if Cost of Attendance exceeds SAI | At full-need-met schools |

In more detail:
- SAI of -$1,500 to $0: Maximum Pell Grant (currently $7,395/year), maximum subsidized Direct Loan eligibility, maximum need-based institutional aid at responsive schools
- SAI of $0 to $7,395: Partial Pell Grant on a sliding scale; subsidized Direct Loan eligibility; need-based institutional aid eligibility at most responsive schools
- SAI of $7,395 to $30,000: No Pell Grant; subsidized Direct Loan still possible if Cost of Attendance exceeds SAI; need-based institutional aid eligibility at full-need-met schools
- SAI above $30,000: Typically no need-based federal aid; unsubsidized Direct Loans (which don’t consider SAI) still available; institutional aid varies by school
These thresholds shift slightly each year as the Pell maximum and the federal poverty level are updated. Check the current-year Pell maximum at studentaid.gov before relying on any specific dollar figure.
How does an old EFC translate to the new SAI?
If you remember a family member’s old EFC and want a quick mental conversion to the new SAI scale, there’s no clean formula — the SAI structurally differs in several ways at once. Loosely: single-child families typically land within roughly 10-20% of their old EFC, multi-child families see a much higher per-child number because the divisor is gone, and low-income families often see a lower one. The patterns in more detail:
- Single-child families typically see an SAI within roughly 10-20% of what their old EFC would have been
- Multi-child families typically see an SAI that’s much higher than their old per-child EFC would have been, because the divisor is gone — closer to the old single-child EFC value
- Low-income families often see a lower SAI than their old EFC, particularly if they qualify under the new poverty-level-based Pell pathway
- Asset-heavy families typically see a higher SAI than the old EFC because the Asset Protection Allowance was drastically reduced
