The $20,000 Shortfall: How Families Bridge the Gap Between Federal Aid and College Costs

Let's say your teen is planning to attend an in-state public four-year university, which is typically the most affordable four-year option.

For the 2025-2026 academic year, the average in-state student paid around $25,500 in tuition, fees, and room and board. You plan to use federal student loans, but first-year undergraduate students can only borrow $5,500 in their first year. Suddenly, that gap between federal aid and college costs has become a chasm.

If your student’s financial aid package comes up short, don’t panic. There are many ways to pay for college, bridging the gap between federal aid and college costs. Here’s what you need to know about paying for it, especially if you’re a middle-income earner.

What FAFSA Covers and How It Works

When you apply to school, you and your parents must complete the Free Application for Federal Student Aid (FAFSA), which usually opens in October at studentaid.gov. Most schools require it before they offer you an aid package.

Your FAFSA determines eligibility for federal student loans, work-study, Pell Grants, and other need-based aid. Most colleges also use the data to award their own grants, scholarships, and merit-based aid.

Why Middle-Class Families Often Get Left Out

The problem is, you may not qualify for everything you need, especially if you're middle-class, because your finances may look better on paper than they do in practice.

When this occurs, it isn't a planning failure. It's a structural mismatch of rising college costs and stagnant loan limits, said Jeni Burckart, vice president of Healthcare and Workforce Services at Tuition.io. "Federal student loan limits haven't changed in decades. As tuition has gone up, there's no loan money to cover that."

How Far Behind Federal Loan Limits Have Fallen

The $5,500 first-year loan cap hasn't changed since 2008, but average published tuition and fees at public four-year colleges have climbed from roughly $7,020 to $11,610 over that span, a 65% nominal jump, according to data from the College Board.

First-year dependent undergraduates can borrow up to $5,500 in a combination of subsidized and unsubsidized loans. Borrowing limits increase slightly each year, but the total cap across all four years remains just $31,000:

• Year 1: Up to $5,500
• Year 2: Up to $6,500
• Years 3 and 4: Up to $7,500 per year

For most families, it's not enough. Over four years at an in-state public university, the cumulative gap between federal loans and total costs could run $60,000 to $80,000. At private universities, that figure doubles or triples. The average cost of a private four-year institution is around $60,000 a year, and some elite schools can reach $100,000.

As the cost of higher education continues to rise, families are scrambling to find funds to cover what loans and scholarships don't.

The free moves below could help close the $20,000 gap before you ever fill out a loan application.

Appeal the Financial Aid Package

"You can actually appeal the financial aid award, and I don't think a lot of families are aware of this," said Burckart.

If your financial situation has changed since you filled out the FAFSA, such as a divorce, unexpected medical expenses, job loss, or even a competing offer from another school, you may have grounds to appeal. Pick up the phone and call the financial aid office to discuss options.

Apply for All the Scholarships

Reach out to your high school counselor, civic groups, your parents' employers, and any other professional associations your parents belong to, and ask them about scholarship opportunities. Try local scholarships as well as national ones. No amount is too small. "Even a $500 award is a great return on your time," said Burckart.

Rethink Your College Choice

Consider starting at a local community college. Go for two years and then transfer to a four-year school, which can be a less expensive path toward the same goal. Most credits transfer between regionally accredited schools, and the diploma still comes from the four-year institution.

If you're still facing a shortfall, two solid options remain: federal Parent PLUS loans and private student loans. The right call depends on your credit, financial profile, comfort with a cosigner, and how much you value the federal safety net.

Parent PLUS Loans

Unlike federal student loans, which the student takes out, direct PLUS loans, also called Parent PLUS loans, are for parents. To date, approximately 3.6 million parents hold them, according to the U.S. Department of Education.

Burckart explains that historically, families chose Parent PLUS, established in 1980, because of the federal safety net, including:

• Income-driven repayment (IDR) plans
• Deferments
• Death and disability discharges
• Public Service Loan Forgiveness eligibility

In addition, Parent PLUS loans had no borrowing cap. That ends on July 1, 2026. Under the new rules, you can only borrow up to $20,000 per year and $65,000 total per dependent. Loans taken out on or after that date also have just one repayment option: a new standard repayment plan.

While that might mean less federal debt for parents, it could mean less money available for college.

Private Student Loans

You can compare private student loans offered by banks, credit unions, and online lenders. Most require the student to be the borrower with a parent cosigner. Key things to know:

• Interest rates are credit-based: Your credit score plays a big role in what you're offered, with rates starting around 2.84% and capped at 17.95%.
• Strong credit can beat the federal rate: "Depending on your credit score, somebody who's sitting there with good assets and income and has a credit score of 830, they can probably beat it in the private market," said Burckart. "It may actually be the cheaper source of money for them."
• No federal protections: Unlike Parent PLUS loans, private student loans don't come with income-driven repayment options, deferments, or discharge provisions.

Here's what borrowing $20,000 looks like in dollars:

That's $42 less a month and roughly $5,850 saved with a private loan, so it's worth considering if you qualify. The downside is you don't get the federal protections that come with Parent PLUS loans.

Parent PLUS vs. Private Loan: Which Is Right for You?

• Pick Parent PLUS: Your credit is fair or has some dings, you want the benefits of a federal loan, or you don't want to ask anyone to cosign.
• Pick a private loan: You or a cosigner has credit in the mid-700s or higher. You'll likely land a rate well below 9.07%, skip the origination fee, and get repayment terms of up to 20 years, depending on the lender.

If your parents are nearing retirement, they should model any loan payments against their estimated retirement income, said Burckart. "I just think that is so critical."

If you don't want to take out a Parent PLUS loan or a private student loan, there are other ways to bridge the gap between your federal loans, merit and need-based aid, and grants:

• Home equity loan or HELOC: If you have sufficient equity in your home, you could use a home equity loan or home equity line of credit to cover any college cost overage. The risks are high, though, because your home serves as collateral for the loan.
• Retirement account loan: Some employer plans allow you to take short-term loans against your retirement savings plans, like a 401(k) or 403(b), allowing you to borrow up to $50,000 or 50% of your vested balance, whichever is less, with five-year terms. The downsides are losing out on market gains, and if you quit or lose your job, the loan may come due in full.

Frequently, middle-class and even upper-middle-class families get squeezed when it comes time to pay for college. While it may feel like the system is working against you, it is possible to find ways to pay for your child’s education when federal student loans aren’t enough.

Can grandparents use a Parent PLUS loan?

No, grandparents and legal guardians can't qualify for them. Only parents and, in some cases, stepparents, but only if their income was included on the FAFSA.

Should I tap retirement savings to pay for my child's college?

Most experts advise against it. "You don't have to 'panic borrow' or 'panic extract' money from your retirement," said Burckart. It can put you at a financial disadvantage and your student in the future.

What happens to Parent PLUS loans if the parent or student dies or becomes disabled?

Federal Parent PLUS loans are discharged if the parent borrower dies or becomes permanently disabled. If the student passes away, the loans are also forgiven.
