What is the FAFSA?

The FAFSA (Free Application for Federal Student Aid) is a form that high school seniors and college students complete to be considered for financial aid, including Pell Grants, federal work-study programs, federal student loans, and state or school financial aid awards.

Why it matters

The FAFSA is the gateway to billions of dollars in financial aid. Even if you think you won’t qualify for need-based aid, completing the FAFSA is essential — many schools require it for merit-based scholarships, too.

How does the FAFSA work?

Colleges need a completed FAFSA form to determine your eligibility for financial aid. After you submit your FAFSA, you’ll receive a FAFSA Submission Summary from the office of Federal Student Aid within a few days (online) or two weeks (mail). This contains your Student Aid Index (SAI) — an index number from –1500 to 999999, calculated from the information you provided.

Your college uses your SAI to calculate how much and what types of financial aid you’re eligible for. You’ll then receive aid offers or award letters from each school that accepted you.

Key term: Student Aid Index (SAI)

The SAI replaced the Expected Family Contribution (EFC) starting with the 2024-25 school year. It’s calculated from income, assets, family size, and other factors.

Who qualifies?

To qualify for federal student aid, you must:

  • Be a U.S. citizen or eligible noncitizen
  • Have a valid Social Security number
  • Be enrolled or accepted in an eligible degree or certificate program
  • Maintain satisfactory academic progress
  • Sign the certification statement
  • Have a high school diploma, GED, or equivalent

You must also show financial need for need-based aid and be enrolled at least half-time for Direct Loans.

How to apply

You can complete the FAFSA in one of two ways:

  1. Online (recommended): Complete it at studentaid.gov
  2. Paper: Fill out the FAFSA PDF form, print it, and mail it

You’ll need an FSA ID — a unique username and password — to log in and sign your form electronically. Create yours at studentaid.gov. Your FSA ID is only for you — don’t share it, even with your parents.

FAFSA renewal

You must renew your FAFSA each year. Log in to your account, select “FAFSA Renewal,” and update any changed information. Use the IRS Data Retrieval Tool (IRS DRT) to automatically transfer your tax information.

Adding schools

You must list at least one school on your FAFSA. For the 2026-27 online application, you can list up to 20 schools. Find your school’s Federal School Code at studentaid.gov.

Common questions

How much money does FAFSA give?
The amount depends on your Student Aid Index (SAI). Need-based aid includes Pell Grants, FSEOG, Direct Subsidized Loans, and Federal Work-Study. Non-need-based aid includes Direct Unsubsidized Loans, Federal PLUS Loans, and TEACH Grants. Your school’s financial aid office calculates your specific award based on your SAI and the school’s cost of attendance.
Do I need FAFSA for student loans?
Yes. You must complete the FAFSA to be considered for federal student loans. Four types are available through the Direct Loan Program: Direct Subsidized Loans, Direct Unsubsidized Loans, Parent PLUS Loans, and Direct Consolidation Loans.
How long does FAFSA take to process?
You’ll receive your FAFSA Submission Summary within a few days of online submission or about two weeks if you mailed a paper form.
How do I check my FAFSA status?
Log in at studentaid.gov. Your application status will be available on the “My FAFSA” page. For paper submissions, allow 7-10 business days from when you mailed it.
How do parents log into FAFSA?
Parents of dependent students must create their own FSA ID to log in and electronically sign their student’s FAFSA form. As of December 2023, parents without a Social Security number can create an FSA ID. If you have siblings in college, your parents can use the same FSA ID for all applications.
Am I a dependent or independent student?
FAFSA has specific rules for dependency status that differ from IRS rules. Most undergraduate students under 24 are considered dependent. See TUN’s dependency status guide for details.
Can I add more than 20 schools?
The 2026-27 online FAFSA allows up to 20 schools. To add more, delete a school that has already processed your aid application and add a new one. Note: removed schools lose access to new information you provide.
