What is the Student Aid Index tool and how does it work?

The Student Aid Index (SAI) is new measure that replaces the old "Expected Family Contribution" (EFC)

Student Aid Index

The Student Aid Index tool estimates a student’s federal Student Aid Index (SAI) and potential Pell Grant using Department of Education methodology.

Advisors enter household, parent, student, income, and asset information for the applicable FAFSA award year. The tool then:

  • Calculates an estimated SAI for each student
  • Breaks down parent, student-income, and student-asset contributions
  • Estimates the scheduled Pell Grant
  • Provides a worksheet showing how the result was calculated
  • Models what-if scenarios involving base-year income, asset ownership, and the number of children in college

A lower SAI generally indicates greater potential need-based aid eligibility; a higher SAI indicates less. SAI values for multiple students should not be added together. Pell figures are full-time, full-year estimates and may be prorated based on enrollment.

The results are planning estimates—not an aid offer, bill, or guarantee. Schools determine actual aid packages, and CSS Profile schools may use substantially different formulas.

This SAI tool is generally most useful when college is relatively near—especially the year or two before enrollment and while the student is in college. That’s because SAI is based on FAFSA inputs that can change materially over time: parent and student income, assets, household size, marital status, and the specific tax year used by FAFSA. A projection made when a child is 8 or 10 can be directionally interesting, but it is usually too speculative to be very actionable. That said, the College Funding tool does allow you to make long-term SAI estimates based on projected future AGI and other financial measures in an Income Lab plan. These estimates can be helpful in at least “ballparking” future grant aid and savings needs.

 

"What If" Tools

The Student Aid Index tool has three “what-if” levers on the What Ifs input tab. Each one re-runs the federal SAI formula on a modified copy of the household and shows before, after, and the change on the What Ifs analysis tab.

1. Move an asset between the student and the parents

Enter an amount, a direction (Student → parents or Parents → student), and a bucket to move assets from:

  • Investments (brokerage, UGMA/UTMA)
  • Cash, savings and checking
  • 529 / Coverdell

The move is capped at the balance already reported on the source side. Student assets are assessed at a flat 20% with no protection allowance. Parent assets are converted at 12% and then run through the parent assessment schedule, so the effective rate is much lower (about 2.6–5.6 cents per dollar). The result quotes the household’s actual SAI change.

2. Realize income in the base year

Enter extra income for the prior-prior year (i.e., 2 years ago) that prices this award year. A negative amount models deferring income out of that year. The options for income type are:

 

Kind How the formula sees it
Roth conversion
Added to AGI; ordinary income, not earned
Realized long-term capital gain
Added to AGI
Traditional IRA / 401(k) distribution
Added to AGI
Wages or bonus
Added to AGI and to earned income (FICA and employment-expense allowances move too)
Business / K-1 income
Same as wages
Tax-exempt (municipal) interest
Stays out of AGI and is added back on the FAFSA, so there is no offsetting tax allowance

 

When a base-year tax return is loaded, Penny’s tax engine prices the extra federal income tax and credits it as a FAFSA allowance, so the SAI change is net of that tax. State tax is shown as a real cost and is not an allowance. The results add three metrics: cents of SAI per dollar of income, the federal tax change, and the all-in first-year cost (federal tax + state tax + SAI change).

The income what-if is a sensitivity check on the award year’s base year (which can no longer be changed if it is in the past). The planning value of this sensitivity check is what it tells you about years that are still open and how different levels of income can change SAI.

 

How does SAI differ from “Expected Family Contribution” (EFC)?

The Student Aid Index (SAI) replaced the Expected Family Contribution (EFC) beginning with the 2024–25 FAFSA. This was more than a rename: the underlying formula changed in several important ways. COA below means “cost of attendance”.

 

  Old EFC Current SAI
Meaning Presented as the family's "expected contribution" Explicitly an eligibility index, not what the family is expected to pay
Minimum value Generally $0 Can be as low as –$1,500
Multiple children in college Parent contribution was generally divided among children in college No sibling-in-college discount; each student's SAI is calculated independently
Pell Grant determination Closely tied to EFC Pell eligibility now also uses separate income/family-size rules, not simply SAI
Need calculation COA − EFC = financial need Generally COA − SAI = financial need, subject to other aid rules
Terminology Sounded like an actual amount the family was supposed to pay Designed to avoid that implication

 

The biggest practical changes are:

  • SAI can be negative. An SAI of –$1,500 identifies students with particularly high financial need. It doesn't mean the school pays the family $1,500; it can increase calculated need. Federal Student Aid describes SAI as an index ranging from –1,500 to 999,999.
  • The old "multiple kids in college" benefit disappeared. Under EFC, if a family had, say, two children attending college simultaneously, the parental contribution was effectively apportioned between them. Under SAI, having another child in college doesn't reduce the first child's SAI in that way. That can produce dramatically higher aid-index numbers for families with overlapping college years.
  • SAI is deliberately not called a contribution. The Department of Education emphasizes that SAI is not the amount the family is expected to pay, nor is it an aid award. Schools use it as one input in constructing financial-aid packages.

The FAFSA simplification legislation also changed some underlying inputs and calculations. So you generally shouldn't treat SAI as simply "EFC with a new label." An old EFC calculator cannot reliably be reused to calculate SAI.
