How does FAFSA work? FAFSA vs CSS Profile and the Pell Grant

When your student reaches high school, three names keep coming up: the FAFSA, the Pell Grant and the CSS Profile. They sound alike, but each does a different job. Here is how each one works, in plain language, with a link to the official source for every fact.

A quick note first. I am a dad and a Doctor of Chiropractic, not a financial aid officer. Aid rules, amounts and deadlines change every year, so confirm each step on StudentAid.gov and with each college's financial aid office. UpOnly Learning does not promise any aid.

The short version

How does the FAFSA work?

Colleges and career schools use the FAFSA form to decide how much financial aid a student is eligible to receive. That aid can include grants, scholarships, work-study and loans (StudentAid.gov, FAFSA). The form is for any student, at any income, who wants to be considered for federal, state and school aid. So do not skip it because you think you earn too much.

The FAFSA becomes available each fall for the upcoming school year (Federal Student Aid), and students apply again every year. There is a federal deadline, but each state has its own deadline and each college may have its own too (FAFSA deadlines). If you miss a state deadline, file anyway: it does not affect eligibility for federal aid.

What happens after you file

Your answers produce a number called the Student Aid Index, or SAI (how aid is calculated). The SAI is not a dollar amount, and it is not what your family is expected to pay. The financial aid office subtracts the SAI from the cost of attendance to find the student's financial need. A negative SAI means higher need.

Who fills it out

Only students and their families can complete their FAFSA, and it is always free to fill out and submit (FTC). Students should never share their FSA ID with anyone, including companies or consultants. If someone offers to file it for a fee, say no. There is also no age limit for federal student aid, so an adult going back to school files the FAFSA too (Federal Student Aid, adult students).

What the Pell Grant is

The Federal Pell Grant usually goes only to undergraduates who show exceptional financial need and have not earned a bachelor's, graduate or professional degree (StudentAid.gov, Pell Grants). The amount depends on the Student Aid Index from the FAFSA, the cost of attendance, full-time or part-time status and a few other factors.

The maximum award is set for each award year, and StudentAid.gov lists the current amount, so check it there. A student can receive the Pell Grant for no more than 12 full-time terms or the equivalent, roughly six years. Unlike a loan, it does not have to be repaid, except in certain circumstances.

FAFSA vs CSS Profile

The CSS Profile is an online application run by College Board. Colleges and scholarship programs use it to award their own, non-federal aid (About CSS Profile). It does not replace the FAFSA. For federal aid, students must still complete the FAFSA.

Not every college uses it. Check each college's information to see whether it requires the CSS Profile; a list of participating schools is online. Some schools may also ask divorced or separated parents to complete separate applications. Most students complete it in the fall of senior year, and schools may have different deadlines.

The CSS Profile has a fee. Without a fee waiver, it costs $25 for the first application and $16 for each additional report (Complete the application). Undergraduates living in the U.S. may file it for free if their family adjusted gross income is up to $100,000, if they qualified for an SAT fee waiver, or if they are an orphan or ward of the court under age 24 (CSS Profile fee waivers).

Grants vs loans: what you keep and what you pay back

• Grants and scholarships are money that does not need to be repaid. Scholarships come from schools, employers, nonprofits, communities and many other groups (StudentAid.gov, scholarships).
• Work-study is money the student earns at a part-time job, for students with financial need, at schools that take part. Funds are limited, so apply for aid early (StudentAid.gov, work-study).
• Loans are borrowed money, paid back with interest. With Direct Subsidized Loans, for undergraduates with need, the government pays the interest while the student is in school at least half-time. With Direct Unsubsidized Loans, the borrower pays all the interest (Direct Loans). Rates are set each year (current rates).
• Parent PLUS loans are the parent's debt, not the student's, and they have the highest interest rates of the federal student loans (evaluating aid offers).

When aid offers arrive, sort every line into free money, earned money and borrowed money. Compare net price, not sticker price. Every college in the federal aid programs must post a net price calculator on its website, and the Net Price Calculator Center links to them.

What to have ready

• The college list, with each college's financial aid deadlines and requirements (Common App, 12th grade checklist) and your state's FAFSA deadline.
• Your family's financial information. The CSS Profile asks about income, assets and expenses (CSS Profile), and StudentAid.gov explains what the FAFSA asks.

A short step list

1. In the summer between junior and senior year, start researching scholarships. Some deadlines are as early as a year before college starts (StudentAid.gov).
2. Build the college list and mark which schools require the CSS Profile.
3. When the FAFSA opens in the fall, file it on the official site, for free.
4. If a college requires it, file the CSS Profile in the fall of senior year. Check for a fee waiver first.
5. Sort each aid offer into grants, work-study and loans, and compare net price.
6. Tell the college about outside scholarships, since total aid cannot be more than the cost of attendance.
7. File the FAFSA again each year.

If your student is not a U.S. citizen

Federal student aid is for U.S. citizens and eligible noncitizens, a group that includes U.S. nationals and permanent residents with a green card. Students in the U.S. on an F-1, F-2 or M-1 student visa, or a J-1 or J-2 exchange visitor visa, cannot receive federal student aid (StudentAid.gov, non-U.S. citizens). They may still find scholarships and other aid, and many colleges give their own aid to international students (CSS Profile). Ask each college. Our international students page covers visas and proof of funds.

Watch for scams

You never have to pay to find scholarships or aid, and you should never pay to apply for a scholarship. Walk away from any offer that charges a fee, asks for a card or bank number to "hold" a scholarship, or says your student is a finalist in a contest they never entered. Report scams at ReportFraud.ftc.gov and to your state attorney general (FTC).
