FAFSA Student Aid Index (SAI) Estimator
Use this calculator to get an estimated Student Aid Index (SAI) based on simplified FAFSA methodology. Your actual SAI may vary. This calculator is for estimation purposes only and should not replace completing the official FAFSA.

Understanding Your Student Aid Index (SAI)
The Student Aid Index (SAI) is a crucial number that colleges use to determine how much federal student aid you are eligible to receive. It's calculated based on the financial information you provide in your Free Application for Federal Student Aid (FAFSA). A lower SAI generally indicates a higher financial need and eligibility for more federal, state, and institutional aid.
What is the SAI?
The SAI replaced the Expected Family Contribution (EFC) starting with the 2024-2025 FAFSA cycle as part of the FAFSA Simplification Act. Unlike the EFC, the SAI can be a negative number, down to -1500. An SAI of -1500 signifies the highest level of financial need and typically qualifies a student for the maximum Pell Grant award.
Key Factors Influencing Your SAI:
- Adjusted Gross Income (AGI): Both the student's and parent(s)' (if dependent) AGI are primary factors. The FAFSA assesses a portion of this income after applying various allowances.
- Assets: Cash, savings, and investments held by both the student and parents (if dependent) are considered. Importantly, certain assets are excluded, such as the family's primary home, retirement accounts (401k, IRA), and small businesses with fewer than 100 full-time employees.
- Household Size: The number of people in your household impacts the income protection allowance (IPA), which is the portion of income protected from being assessed for aid. Larger households generally have higher IPAs.
- Number in College: For dependent students, the number of family members (excluding parents) attending college can significantly reduce the assessable income, as the assessable amount is divided among them.
- Student's Marital Status/Dependency: Independent students generally have a higher income protection allowance, and their parents' income and assets are not considered at all. Dependency status is determined by specific FAFSA questions, not just parental support.
How the SAI is Used:
Colleges use your SAI to calculate your financial need using the following formula:
Cost of Attendance (COA) – Student Aid Index (SAI) = Financial Need
Your financial need determines the amount of need-based aid (like Pell Grants, Subsidized Loans, and some institutional grants) you can receive. Even if your SAI is positive, you may still qualify for federal student loans or other forms of aid.
Important Considerations:
- This Calculator is an Estimate: The actual FAFSA calculation is highly complex and involves many specific rules, allowances, and assessment rates that are not fully replicated here. This calculator provides a simplified estimate based on common FAFSA principles for general guidance.
- Tax Information: The FAFSA primarily uses tax information from two years prior to the academic year (e.g., for the 2024-2025 FAFSA, 2022 tax data is used).
- Special Circumstances: If your family's financial situation has changed significantly since the tax year used on the FAFSA (e.g., job loss, divorce, high medical expenses), you can appeal to your college's financial aid office for a "professional judgment" review.
- Completing the FAFSA: Always complete the official FAFSA form at StudentAid.gov for an accurate and official determination of your federal student aid eligibility.
