How does college financial aid actually work?
The FAFSA is the whole game.

What is the Student Aid Index (SAI), and what replaced?

The SAI is the single number the FAFSA formula produces from your family's financial picture. It replaced the Expected Family Contribution (EFC) starting with the 2024–25 award year under the FAFSA Simplification Act. Despite the old name, neither number was ever a bill you had to pay; both are just an index a school plugs into its own math.

Here is the whole equation a school uses: Cost of Attendance − SAI = your financial need. If a school costs $40,000 all-in and your SAI is $12,000, your demonstrated need is $28,000. The school then tries to meet some or all of that need with a mix of aid types. A lower SAI means more need, which means more aid you qualify for verify×DON'T TRUST, VERIFYClaim: The SAI replaced the EFC, and aid is calculated as Cost of Attendance minus SAI, with parent income the largest factor and retirement accounts excluded from assets.Verify at: Federal Student Aid: How aid is calculated ↗Federal Student Aid documents the SAI formula, the CoA-minus-SAI need calculation, and which assets are counted..

One meaningful change: the SAI can go as low as -1,500, where the old EFC bottomed out at 0. That negative floor exists to distinguish the most financially strained applicants from those who simply hit zero, so the neediest students surface for the largest awards.

What counts on the FAFSA, and how hard is each piece hit?

Not all money is weighed equally. Income matters far more than assets, and the student's money is penalized much harder than the parents'. Knowing the rank order is the entire game, because it tells you where positioning actually moves the number and where it is a rounding error.

Assessment rates and allowances are set annually by the Department of Education; figures reflect the FAFSA methodology as of the 2025–26 and 2026–27 award years. Verify current-year numbers before relying on them.

The takeaway from the rank order: because parent income is assessed up to 47% and parent assets at most 5.64%, chasing asset tricks is mostly noise. And because student assets get the brutal 20% flat rate with no allowance, money titled to the student is the worst possible place to park college savings verify×DON'T TRUST, VERIFYClaim: Parent assets are assessed at up to 5.64% and student assets at a flat 20%, while retirement accounts and the primary home are excluded.Verify at: Federal Student Aid: How aid is calculated ↗Federal Student Aid publishes the asset assessment rates and the list of excluded assets used in the SAI formula..

How does a 529 plan affect financial aid?

A parent-owned 529 is treated as a parental asset, which means it gets that light ~5.64% touch. $50,000 saved in a parent-owned 529 adds at most about $2,820 to your SAI, a small price for tax-free growth. This is exactly why the 529 is the default college-savings vehicle: it barely dents aid and the earnings are tax-free when used for qualified expenses. The mechanics are covered on the 529 plan page and the 529 account guide.

The bigger change is the grandparent-owned 529. Under the old rules, distributions from a grandparent's 529 counted as untaxed student income on the next FAFSA, assessed at up to 50%, so a $10,000 gift could cut aid by up to $5,000. That penalty is gone. Under the simplified FAFSA, distributions from a grandparent-owned (or any non-parent-owned) 529 are no longer reported as student income at all. A grandparent can now pay tuition directly from a 529 with zero FAFSA consequence.

One nuance: the FAFSA no longer asks about non-parent 529s, but the CSS Profile (below) still can. At schools that use it, a grandparent 529 may still be visible, so the loophole is cleanest at FAFSA-only schools.

What are the federal aid types, and which are free?

Filing the FAFSA unlocks a stack of federal programs. They are not equally good; grants are free money and loans have to be repaid with interest. Take them strictly in that order.

• Pell Grant — free, never repaid. Maximum award is $7,395 for the 2025–26 year, targeted at students with low SAIs. This is the first dollar you want.
• Federal Work-Study — earned. A part-time job, usually on campus, whose earnings don't count against next year's FAFSA. Awarded based on need and school funding.
• Direct Subsidized Loan — borrowed, need-based. The government pays the interest while you're in school at least half-time. Better than unsubsidized because interest doesn't accrue during school.
• Direct Unsubsidized Loan — borrowed, not need-based. Available regardless of SAI, but interest accrues from day one. First-year dependent undergrads can typically borrow up to $5,500 total (subsidized + unsubsidized combined).

Federal student loan interest rates are set each year by Congress and are fixed for the life of the loan. Before borrowing a dollar, understand what you're signing up for; the student loan strategy page covers repayment, forgiveness, and how much debt is actually sane relative to your expected starting salary.

What's the difference between merit aid and need-based aid?

Need-based aid is tied to your SAI. The lower your SAI relative to a school's cost, the more grants, subsidized loans, and work-study you're offered. This is the bucket the FAFSA feeds directly, and it's why the FAFSA is non-negotiable even for families who assume they "won't qualify."

Merit aid ignores your finances entirely. Schools hand it out to attract students they want: strong GPA, test scores, a specific talent, or simply to lure students who could otherwise go elsewhere. A family with a $60,000 SAI (little to no need-based aid) can still land a $20,000/year merit scholarship at a school where their student is a strong applicant.

The practical move: even wealthy families should file the FAFSA (many merit scholarships and some schools require it on file), and every family should target a range of schools where their student sits in the top 25% of admitted applicants, because that's where merit dollars concentrate. Merit aid is often the larger lever for middle- and upper-income families who see thin need-based awards.

What is the CSS Profile, and when should you file?

The FAFSA is universal, but around 200+ mostly private and selective colleges also require the CSS Profile to award their own institutional grant money. It digs deeper than the FAFSA: it can ask about home equity, small-business value, and non-custodial parent income, and unlike the FAFSA it charges a fee (roughly $25 for the first school, ~$16 each additional, with fee waivers for lower-income families). If a school on your list requires it, filing only the FAFSA leaves their institutional grants on the table.

File as early as the form opens. The FAFSA typically opens for the coming academic year in the fall (historically October 1, though the simplified-form rollout pushed some recent cycles to December). Much aid, especially state grants and campus work-study, is first-come-first-served from a fixed pool, so a student with an identical SAI who files in October can out-earn one who files in March purely on timing verify×DON'T TRUST, VERIFYClaim: The FAFSA is the primary federal aid application and should be filed as early as it opens because some aid is awarded first-come, first-served.Verify at: Federal Student Aid: Apply for the FAFSA ↗Federal Student Aid explains what the FAFSA is, when it opens, and that some aid is limited and awarded on a first-come basis..

You must refile the FAFSA every year; aid is not carried forward. Set a calendar reminder for the fall of each year your student is enrolled. If you're building the college fund itself, start on the kids and money page and keep the savings in the parent's name, never the student's.
