New on FinoLib · Volume V: Personal Finance
I have added a new article to FinoLib, my finance education website: FAFSA Example: One Family’s First Year of College Aid, part of Volume V: Personal Finance. It is part 2 of a 2-part guide. This page gives you the core of the topic in expert but plain language; the full article goes much deeper.
A closer look
Vol. I’s Part 8.4 walked through mortgage lending from the industrial side — origination, closing, post-closing, servicing, the securitization machine that turns thousands of individual loans into mortgage-backed securities. This Part is the view from the other side of that same desk: the household deciding whether, when, and how much to borrow, in an environment where the 30-year fixed rate sat at 7.28% in Freddie Mac’s survey of Oct 1, 2026, up from 6.34% a year earlier — a very different market from the sub-3% era Vol. I uses as its 2021 reference point.
A worked example
Worked Example — One Family’s First Year
A dependent first-year student at an in-state public university; parents file jointly with modified AGI of $78,000; SAI $4,000. Cost of attendance (illustrative): tuition and fees $11,500 + housing and food $13,000 + books, transport and personal $3,500 = $28,000. Grants: Pell $7,395 − $4,000 = $3,395; state grant $2,000 and college scholarship $3,000 (illustrative) — total $8,395. Net price = $28,000 − $8,395 = $19,605. Work: $2,500 of work-study wages leaves $17,105 to cover. Funding the $17,105: $6,000 from a 529 for housing and food, $5,605 of family cash (covering at least $4,000 of tuition), and a $5,500 first-year federal Direct Loan: $6,000 + $5,605 + $5,500 = $17,105.
Decision rule
File the FAFSA for every year the student might enroll, as soon as it opens. Then, for each student in the first four years: if joint MAGI is below $160,000 ($80,000 single), make sure $4,000 of tuition, fees and course materials is paid with cash, a federal loan, or grant money elected as taxable, and claim the full AOTC.
The costliest mistake
Paying every dollar of tuition from the 529 and claiming no education credit. For a family below the phase-out, that forgoes $2,500 a year, $10,000 over four years, often because the 1098-T arrives showing tuition “paid” and nobody checks which money paid it. Even when the 529 is the only money available, Option C in the worked example recovers $2,148 a year.
Research: Does Filling Out the Form Change Outcomes?
The strongest evidence comes from a randomized experiment. Bettinger, Long, Oreopoulos and Sanbonmatsu offered low-income families visiting H&R Block tax offices immediate help completing the FAFSA, plus an estimate of their aid. High school seniors whose parents received that help were 8 percentage points more likely to have completed two years of college within three years, 36% against 28%; families given only the aid estimate, without help with the form, saw no improvement (Quarterly Journal of Economics, 2012).
Why It Matters
In the example, a $28,000 sticker price becomes $9,105 of family money and a $5,500 loan. A family that skipped the FAFSA would have lost $3,395 of Pell, likely the state grant, and possibly the scholarship, and would have borrowed the difference at rates set out in 4.1. Filing the form is free; not filing it is the single most expensive omission in paying for college.
Recap
What you pay for college is the net price, the cost of attendance minus grants and scholarships, and the FAFSA is the gateway to most of them: the 2027–28 form opened on September 23, 2026, and its Student Aid Index measures need rather than setting a bill.
More from the article
■1 — Grants, scholarships, and the AOTC or Lifetime Learning Credit — Free money; never repaid
■2 — Work-study, part-time work, savings and 529 money — Costs effort or past saving, not future income
■3 — Federal Direct Loans — Fixed rates, RAP, PSLF eligibility, death and disability discharge (4.1–4.3)
■4 — Parent PLUS (now capped, 4.2), then private loans — Higher cost or fewer protections; borrow last and least
