What this result does not account for
- Pell printed as linear estimate — the official schedule governs
- No institutional-aid modeling
In short: A 30,990 cost of attendance against an SAI of 6,200 leaves 24,790 of demonstrated financial need — the gap that need-based aid exists to fill. The Pell arithmetic the index allows: 7,395 maximum minus your SAI prints an estimated 1,195 federal grant. Below zero the index bottoms at −1,500 and packaging treats it as 0; past 14,790 federal Pell eligibility ends entirely.
Formula
need = COA − SAI ··· Pell est = 7,395 − SAI (SAI 0–14,790) ··· SAI floor −1,500 ··· negatives package as 0
The Student Aid Index replaced the Expected Family Contribution with the simplified FAFSA (from the 2024–25 cycle). Each school subtracts your SAI from its cost of attendance to get demonstrated need — the ceiling on need-based aid. The SAI can dip to −1,500, flagging the deepest need; every negative packages as zero. Pell runs from a 7,395 maximum (2026–27) down to zero at an SAI of 14,790 — the page prints the linear estimate only; the actual schedule has minimums and enrollment rules.
Worked Example
- Enter the school's published COA.
- Enter your SAI from the FAFSA summary.
- Read the need gap and the Pell estimate.
- Remember: need is a ceiling, not an offer.
Defaults: 30,990 COA, SAI 6,200 → need 24,790, Pell estimate 1,195. The floor drive (−1,500) keeps need at 30,990 — negatives package as zero — with full 7,395 Pell; the 16,000 drive kills Pell (over 14,790) but still leaves 14,990 of need at this COA.

Methodology & Editorial Standards
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Financial Aid Calculator — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
What is the SAI?
The Student Aid Index — the number the simplified FAFSA computes from your family's income, assets and household size, replacing the old Expected Family Contribution from the 2024–25 cycle. It is an eligibility index, not a bill: schools subtract it from their cost of attendance to measure need. It can reach −1,500 at the bottom and has no ceiling; home equity and retirement balances are excluded from the formula.
Why did the EFC name change?
Because the old name misled: the Expected Family Contribution was never a bill, just an index. The renaming is also substance — the simplified FAFSA dropped the division among multiple children in college, allowed negative values down to −1,500, and pulled tax data directly from the IRS. Families with siblings saw the biggest shifts.
How does the Pell estimate work?
Linearly: the 7,395 maximum (2026–27) minus your SAI, until eligibility ends at 14,790 — twice the maximum award. The real schedule includes minimum-Pell provisions and enrollment-intensity rules, so the estimate is the formula's spine, not a guarantee. At SAI 6,200 it prints 1,195; at or below zero, the full 7,395.
Does a negative SAI mean more Pell money?
No — every negative SAI earns the same maximum Pell as zero. The negative range exists as a signal: it flags the deepest-need applicants to colleges packaging their own institutional grants. Federal money does not increase below zero, but institutional generosity often tracks the flag.
Is need the same as what I'll pay?
No — need is a ceiling on need-based aid, not an offer. Schools meet different shares of need with grants, work-study and subsidized loans; the unmet remainder is the real planning number. Two schools with identical COA and identical need can leave very different gaps after their aid offices finish.
Where do scholarships fit in the need math?
Outside scholarships are resources: they reduce remaining need dollar-for-dollar in the packaging formulas, and colleges may reduce their own grants to make room — displacement. The award still helps, but rarely adds on top of a full need-based package. The scholarship page prices the award itself; the interaction is office policy.
What if my SAI is higher than the cost of attendance?
Then demonstrated need is zero and need-based aid — Pell, subsidized loans, most institutional grants — is off the table at that school. What remains: unsubsidized federal loans, merit scholarships awarded independent of need, and payment. A 35,000 SAI shows no need at a 30,990 public school but 30,470 of need at a 65,470 private one — need is always relative to the COA.
How do I find my SAI?
On the FAFSA Submission Summary, weeks after filing — the exact number every school on your list receives. The same SAI produces different need at every school because COA varies; the honest comparison shopping happens after award letters arrive, by subtracting each school's gift aid from its own net price.
