How to Calculate Your Expected Family Contribution (SAI) for College

What Is the Student Aid Index?

Starting with the 2024-25 academic year, the Expected Family Contribution (EFC) was replaced by the Student Aid Index (SAI). The name changed, the formula changed, but the core purpose remains the same: it is a number that represents what the government thinks your family can afford to pay for one year of college.

The SAI is not a bill. It is not what you will actually pay. It is a starting point that colleges use to determine your need-based financial aid eligibility. Your actual cost will depend on each school's own aid policies and how much of your demonstrated need they choose to meet.

The Key Inputs

The SAI formula considers several factors, weighted roughly in this order of importance:

Parent Income (biggest factor): This includes wages, salaries, business income, investment income, and other taxable income from the prior-prior tax year. For the 2026-27 FAFSA, that means 2024 tax returns.

Parent Assets: Cash, savings, checking, investments, real estate beyond the primary home, and business assets. Retirement accounts (401k, IRA) and the value of your primary home are excluded.

Student Income: Students have a much larger income protection allowance. The first roughly 9,410 dollars of student income is excluded. After that, 50 percent of student income is assessed.

Student Assets: 20 percent of student assets are assessed, compared to about 5.6 percent for parent assets. This means 10,000 dollars in a student's savings account costs about 2,000 dollars in aid eligibility, while the same amount in a parent's account costs about 560 dollars.

Household Size and Number in College: The formula accounts for household size, but unlike the old EFC formula, the new SAI no longer divides by the number of family members in college simultaneously.

Quick Estimation Method

While the full formula is complex, here is a rough estimator:

For families earning 50,000 to 100,000 dollars with typical assets: expect an SAI between 5,000 and 25,000 dollars. For families earning 100,000 to 150,000: roughly 25,000 to 45,000 dollars. For families above 200,000: the SAI often approaches the full cost of attendance at many schools, though the most expensive private universities still cost more.

These are rough ranges. The actual calculation depends heavily on assets, household size, and state of residence.

What the SAI Does Not Capture

The formula misses a lot. It does not consider: credit card debt, mortgage payments (beyond home value exclusion), car payments, cost of living differences between regions, private K-12 tuition for siblings, medical expenses not covered by insurance, or support for elderly family members.

This is exactly why the professional judgment appeal process exists. If your family has significant expenses not reflected in the SAI, you can and should communicate those to each school's financial aid office with documentation.

The Negative SAI

One of the biggest changes in the new formula: the SAI can now go below zero, down to negative 1,500. Under the old system, the lowest possible EFC was zero. A negative SAI flags a student as having exceptional financial need and may qualify them for additional Pell Grant funding.

How to Check Your Number Before Filing

Do not wait until you file the FAFSA to find out your SAI. Use the Federal Student Aid Estimator at studentaid.gov to get a preliminary number. Several third-party calculators also provide estimates. Knowing your approximate SAI helps you build a realistic college list and set expectations for what you will actually pay at different types of schools.

How This Connects to Your College List

A high SAI does not mean you cannot get financial aid. It means need-based aid at most schools will be limited. Instead, focus on merit-based aid opportunities at schools where your academic profile is strong.
