FAFSA SAI and Pell Grant Estimator (2027-28)

The Student Aid Index (SAI) is the number colleges use to measure a family's eligibility for federal student aid, and this estimator runs the Department of Education's 2027-28 formula on your answers to estimate your SAI and your Federal Pell Grant.

Award year
Pick the year you are applying for. The formula, the tax year and the poverty guidelines change from one year to the next. Applying now for fall 2027. Reads 2025 tax returns.

Your answers

Step 1 of 3: Dependency

Are you a dependent or an independent student?

Select every statement that applies to you.

Dependent students include their parents' income and assets in the formula, and independent students use their own. Answer yes to any of these 7 questions and you count as independent. Dependent here is a federal aid term. It does not depend on whether your parents claim you on their taxes.

Are you a U.S. citizen or an eligible noncitizen?

Do any of these apply to you?

You count as a dependent student The formula uses your parents' income and assets, plus your own. Federal aid defines dependent this way even when you support yourself or your parents do not claim you on their taxes. A financial aid administrator can change a dependent student to independent in documented unusual circumstances, and that is a decision only a college can make.

How the Estimate Works

You are viewing the 2027-28 award year, which reads 2025 tax returns. It is the default because it is the year students applying now for fall 2027 file. The formula, the amounts and the tax year change from one year to the next.

The estimate works by running the Department of Education's published 2027-28 worksheets on your answers, then applying its Pell Grant rules. Nothing here is a rule of thumb. We tested the formula against the test records ED publishes for 2026-27 and 2027-28, and it matches every usable one to the dollar. For 2027-28 it also reproduces the worked example in ED's guide line by line.

  1. Decide dependency from the 7 questions. That picks the worksheet: dependent students, independent students without dependents, or independent students with dependents.
  2. Start with adjusted gross income, add untaxed income, and subtract education credits, taxable grant aid and work-study. Then subtract allowances: income tax paid, payroll taxes, an income protection allowance that rises with household size, and a work-expense allowance of 35% of earned income up to $5,200.
  3. Add assets only if the FAFSA would ask about them. A parent's net worth counts at 12% and a dependent student's at 20%. A dependent student's own available income counts at 50%.
  4. Run the result through the assessment schedule, which turns available income into the SAI. The SAI is never lower than -1,500.
  5. Check the Pell rules. Income above zero and at or below 175% of the 2025 poverty guideline (225% for a single parent) earns the maximum. Otherwise Pell is the maximum minus the SAI, rounded to the nearest $5, while the SAI is 6,655 or less. Past that SAI, a household at or below a separate income line can still earn the minimum, and an SAI of twice the maximum (14,790) or more earns nothing. The Pell dollars and the 14,790 line are (based on 2026-27 amounts) until ED announces 2027-28 amounts.

Key Concepts About FAFSA & SAI

What does the SAI measure?

The SAI measures a student's eligibility for federal student aid. The Student Aid Index is an eligibility number, not a bill. A college subtracts it from the school's cost of attendance to find a student's financial need, and a lower SAI points to more need. The formula starts with income, takes out allowances for taxes and basic living costs, adds a share of the savings the FAFSA asks about, and adjusts for household size. Rapunzl's Paying For College module walks students through the FAFSA and how aid is awarded, and this estimator applies the same worksheets to your own answers.

Why might savings not count toward the SAI?

Savings might not count toward the SAI because, under the 2027-28 rules, the FAFSA only asks about savings and investments in some cases. If anyone in the household received a federal means-tested benefit, it does not ask. Otherwise it asks when AGI is $60,000 or more, when certain tax schedules were filed, or when a Schedule C shows a profit or loss of more than $10,000. Rapunzl built this estimator to apply that rule the way ED's specifications state it, which is why a family below all of those lines can type in savings and see no change.

How does an SAI turn into a Pell Grant?

An SAI turns into a Pell Grant by subtraction: Pell is the maximum award (not yet announced for 2027-28; the 2026-27 maximum is $7,395), minus the SAI, rounded to the nearest $5, as long as that leaves at least the minimum award (not yet announced for 2027-28; the 2026-27 minimum is $740). Two income shortcuts can lift an award to the maximum, and a separate income line can earn the minimum award. At an SAI of twice the maximum Pell Grant (14,790 on 2026-27 amounts) there is no Pell Grant. Rapunzl built this estimator so students and families can change one answer at a time and watch the SAI and the Pell Grant move.

Using This in Class

Teaching the FAFSA? Have students run the three example households above, then change one answer at a time, such as household size or AGI, and watch which number moves. Real family figures stay private, and the examples are enough for a lesson. Our Paying For College module covers the vocabulary and the types of aid, and the FAFSA guide post walks seniors through the form.

Frequently asked questions

The Student Aid Index is a number, calculated from the FAFSA, that colleges use to measure a student's eligibility for federal student aid. It is not the amount a family has to pay. A college subtracts the SAI from its cost of attendance to find financial need. The SAI replaced the Expected Family Contribution (EFC). It can be negative, down to -1,500, which signals higher need. In most cases the SAI appears on the FAFSA Submission Summary after the form is processed.

Possibly. No single income number decides it, and we can't tell any family where it will land. The SAI weighs income after allowances, the assets the FAFSA asks about, household size, and a dependent student's own income and savings, and colleges add their own aid rules. Federal Pell Grants have a hard line: an SAI of twice the maximum Pell Grant (14,790 on 2026-27 amounts) means no Pell Grant. Other aid works differently. Direct Unsubsidized Loans are not based on financial need, according to studentaid.gov, and colleges set their own scholarships. Put your own household into the estimator above for a Pell estimate, then ask each college about its aid.

There is no flat income limit. Pell depends on the SAI. ED has not announced the 2027-28 Pell amounts, so the dollars here use the 2026-27 figures as a placeholder: a maximum of $7,395, and no Pell Grant at an SAI of 14,790 or more, which is twice that maximum. Two income shortcuts sit on top of that. If AGI is above zero and at or below 175% of the 2025 federal poverty guideline for the household (225% for a single parent), the student gets the maximum whatever the formula says. For a household of four in the 48 contiguous states and DC the guideline is $32,150, so those lines are $56,263 and $72,338. Above them, Pell is $7,395 minus the SAI, rounded to the nearest $5, while the SAI is 6,655 or less. A household at or below a separate, higher income line, between 275% and 400% of the guideline depending on the family, can still get the $740 minimum even when the formula leaves less.

The FAFSA does not hand out a dollar amount. It produces your SAI, and each college builds an aid offer from that SAI, its cost of attendance and the other aid you qualify for. This estimator covers two pieces, the SAI and the scheduled Pell Grant for a full-time student for a full year. For a wider federal estimate, use the Federal Student Aid Estimator on studentaid.gov. For what you would pay at one school, use that college's net price calculator, which most colleges publish on their websites.

The 2027-28 SAI formula uses income, taxes paid, the assets the FAFSA asks about, household size, tax filing status, and, for a dependent student, the student's own income and savings. Income starts with AGI plus untaxed income, less education credits and similar offsets. The formula then subtracts allowances (income tax paid, payroll taxes, an income protection allowance that grows with household size, and a work-expense allowance) and counts a share of assets: 12% of a parent's net worth and 20% of a dependent student's. The 2027-28 worksheets have no line for the number of family members in college and no state tax allowance. The source is ED's SAI and Pell Grant Eligibility Guide.

No. This is an estimate built from the Department of Education's published 2027-28 formula, and Rapunzl is not part of the Department of Education. For official results, use the Federal Student Aid Estimator before you apply and the FAFSA form when you apply. The federal deadline for the 2027-28 FAFSA is June 30, 2028, and states and colleges may set earlier ones. Those dates are for the 2027-28 award year, so check studentaid.gov if you are applying for a different one.
