Can my SAI really be negative?

Yes — the official SAI formula can produce a value as low as -1500 for the lowest-income families, which helps schools identify the neediest students for the most generous aid, including the maximum Pell Grant.

Does this tool account for my family's savings and investments?

No — this is an income-only approximation. The real FAFSA formula assesses assets (savings, investments, and sometimes business/farm net worth) separately, which can meaningfully raise a family's real SAI above this estimate.

Why did my sibling's SAI use to lower mine, but this tool doesn't model that?

Correct — that's a real, intentional change. The old EFC formula divided parent contribution by the number of children in college simultaneously; the FAFSA Simplification Act eliminated that step for the 2024-25 FAFSA onward, so this tool (correctly) doesn't model it either.

Is this the exact same graduated tax table the real FAFSA uses?

No — this tool approximates the official multi-column assessment schedule (which runs from 22% to 47%) with 5 simplified bands, since the exact bracket cutoffs are a detailed table beyond what this quick estimator reproduces precisely.

Should I use this instead of filing the real FAFSA?

No — always file the actual FAFSA at studentaid.gov for your real, official SAI. This tool is for rough planning purposes only.

About the FAFSA Financial Aid Estimator

Gives a rough, income-only approximation of the Student Aid Index (SAI) — the number that replaced the Expected Family Contribution (EFC) starting with the 2024-25 FAFSA — from household income, family size, and dependency status, using simplified published formula bands.

How to use it

Select dependency status (most undergraduates under about 24 are dependent).
If dependent, enter parent household size and parent adjusted gross income.
Enter the student's own income (or your own income, if independent).
Read the estimated SAI, broken down by parent and student contribution.

Formula

Dependent students: Parent Income Protection Allowance (IPA) scales with family size (2026-27 anchor: $44,880 for a family of 4); income above the IPA is assessed on an approximate graduated schedule from 22% up to 47%. Student's own income above a $11,770 allowance is assessed at a flat 50%. SAI = parent contribution + student contribution. Independent students (no dependents): income above an $18,310 allowance is assessed on the same approximate graduated schedule.

Worked example

A dependent student, parent household size 4, $75,000 parent AGI, $4,000 student income: parent income above the $44,880 IPA ($30,120) assessed on the graduated schedule gives roughly $7,381 parent contribution; student income falls below the $11,770 student allowance, contributing $0 — an estimated SAI of about 7,381.

2026-27 SAI income protection allowances (approximate)

2026-27 SAI income protection allowances (approximate)
Filer type	Income protection allowance
Dependent student's parents (family of 4)	$44,880
Independent student, no dependents	$18,310
Dependent student's own income	$11,770

Interpreting your result

This is a rough, income-only approximation — not an official calculation. The real 2026-27 FAFSA Student Aid Index also assesses family assets (savings, investments, and for some filers business/farm net worth) separately from income, uses an official multi-bracket assessment table this tool only approximates with 5 bands, and can even go negative (as low as -1500) for the lowest-income families to help target need-based aid. The FAFSA Simplification Act (2024-25 onward) eliminated the old EFC's 'divide by number in college' step entirely — SAI no longer automatically falls just because more than one sibling is enrolled. File the actual FAFSA at studentaid.gov for your real SAI — no unofficial tool, including this one, can substitute for it.

Recommendations

• A negative or very low SAI generally signals strong eligibility for the Pell Grant and other need-based aid — the real SAI can go as low as -1500 for the lowest-income families.
• Since the FAFSA Simplification Act, having multiple children in college at once no longer automatically lowers the family's SAI the way the old EFC formula did — plan financially with that change in mind.
• This tool doesn't model assets at all — a family with modest income but substantial savings/investments will have a real SAI well above what this income-only estimate shows.

Frequently asked questions

It replaced EFC starting with the 2024-25 FAFSA under the FAFSA Simplification Act — similar purpose (measuring ability to pay), but with real formula changes, including dropping the old 'divide by number in college' step.
