Building Your College Funding Stack: How to Think About Cost Layer by Layer

A layered framework for paying for college—start with free money, add work income, borrow federal loans, and use private loans only as a final layer.

Quick Summary

A college funding stack is the combination of all money sources that pay for college: grants, scholarships, work-study, federal loans, and private loans. Start with free money (grants and scholarships), move to work options, then turn to federal loans, and only consider private loans as a final layer. According to Sallie Mae's 2025 research, the average family now covers college costs through family savings (48%), scholarships and grants (27%), borrowed money (23%), and other sources (2%).

Layer 1: Grants and Scholarships (Free Money First)

Grants and scholarships are the foundation of any college funding stack because they don't require repayment. Think of them as the bottom, strongest block in your stack.

Federal Grants come from the government and are primarily need-based. The largest is the Pell Grant, which helps lower-income students. According to College Board research, federal grant aid totaled $53.7 billion in 2024-25, with Pell Grants accounting for $38.6 billion. The number of Pell Grant recipients jumped 22% between 2022-23 and 2024-25.

Institutional Grants come from colleges themselves and have grown significantly. Colleges awarded $85.1 billion in grant aid during 2024-25—more than the federal government gave. This is important because it means colleges are investing heavily in making attendance more affordable.

State Grants and Scholarships vary by where you live, but many states offer grant programs for residents who attend in-state colleges. College Board data shows state grant aid increased from an average of $920 per student in 2013-14 to $1,280 in 2023-24.

Merit and Private Scholarships are awarded based on academic achievement, talents, community service, or other criteria. Sallie Mae reports that 60% of families rely on scholarships, receiving an average of $8,004 per year.

How much does this layer cover? On average, grants and scholarships cover about a third of college costs. Research shows that 63% of all undergraduates receive at least one grant or scholarship, and grants now represent 29% of the average student's financial aid package.

Challenge to Watch

Grants and scholarships alone rarely cover the full cost of college. Only 1.35% of bachelor's degree students receive aid packages that fully cover their expenses. For most families, you'll need additional layers.

Layer 2: Work-Study and Campus Employment

Once you've maximized free money, the next layer is earning money through work-study or campus jobs. These let you contribute to your college costs without taking on debt.

Federal Work-Study is a need-based employment program funded by the federal government. It provides part-time jobs on campus, typically paying at least the federal minimum wage. Work-study earnings count toward your total financial aid package.

Campus Employment includes non-work-study jobs at the college—bookstore positions, library assistants, resident advisor roles, and more. These often offer flexibility around class schedules and give you real-world experience on your resume.

Off-Campus Employment is also an option. Many students work part-time jobs while in school, though balancing work and academics requires careful planning.

Work-study and part-time jobs typically contribute a modest amount to college costs—usually several hundred to a few thousand dollars per year. The real benefit is that this money goes directly toward college without creating future debt obligations.

Layer 3: Federal Student Loans (Structured, Affordable Borrowing)

After free money and work options, federal student loans form the next layer. Federal loans are significantly better than private loans because they offer:

  • Fixed interest rates set by Congress
  • Income-driven repayment plans if you face financial hardship after graduation
  • Forgiveness programs for public service workers
  • Deferment and forbearance options during hardship

Federal undergraduate loans in 2024-25 charged 5.50% interest. In comparison, private loan rates range from 4.50% to 14.00% depending on creditworthiness.

Federal loan types include:

  • Subsidized Loans: The government pays interest while you're in school. You only pay interest after graduation.
  • Unsubsidized Loans: Interest accrues while you're in school, but you don't have to pay it until after graduation.
  • PLUS Loans: Available to parents and graduate students; they have higher limits but also higher interest rates.

According to College Board data, 38.6% of undergraduate borrowers take federal loans, averaging $7,487 annually. The average federal loan debt for 2023-24 bachelor's degree recipients who borrowed was $29,560.

Access federal loans through the FAFSA. You'll need to complete the Free Application for Federal Student Aid to qualify. In 2024-25, 71% of families submitted the FAFSA, though this represents a slight decline from previous years.

Layer 4: Private Student Loans (Use as Last Resort)

Private loans should only be your final layer because they lack the protections and affordability features of federal loans.

Why private loans are riskier:

  • Interest rates are variable or fixed at rates typically higher than federal loans
  • No income-driven repayment plans
  • No forgiveness programs
  • Credit-dependent: your rate depends on your credit score or a cosigner
  • Limited deferment options if you face hardship

Federal student loans represent 90.9% of all student loan debt, while private loans account for just 9.1%. This reflects that most families recognize federal loans are the better option.

When private loans might make sense: Only after you've exhausted federal loans and other aid, and only if your family has carefully considered the long-term cost. Some families use private loans to bridge a gap, but this should be a conscious choice after understanding the higher costs.

Building Your Own Stack: A Real Example

Let's walk through what a college funding stack might look like for a student attending a public four-year university with a cost of attendance of $30,000 per year:

  • Pell Grant: $4,500 (federal need-based grant)
  • Institutional Grant: $5,000 (college's own aid)
  • Merit Scholarship: $3,000 (based on grades/test scores)
  • Work-Study Income: $2,500 (10 hours/week at minimum wage)
  • Federal Subsidized Loan: $3,500 (no interest while in school)
  • Federal Unsubsidized Loan: $2,000 (low fixed rate)
  • Family Contribution: $3,000 (from savings/income)
  • Remaining Gap: $1,000 (consider private loan only if no other option)

This stack layers free money first, then work income, then affordable federal borrowing, minimizing total debt.

Common Roadblocks and How to Navigate Them

Declining FAFSA Completion FAFSA completion dropped to 71% in 2024-25 from 74% the previous year, despite students saying the form was easier. Completing the FAFSA is essential—it's how you qualify for federal grants, work-study, and federal loans. Start early and use the IRS Data Retrieval Tool to simplify the process.

Unmet Financial Need Even with all layers of aid, many families still face a gap. Nearly four out of five students had to cover at least half their college costs through family contributions, work, or loans. If this applies to you, appeal your financial aid package. Many colleges have funds available and may increase aid upon request.

Difficulty Balancing Work and School Working while in college supports your funding stack, but too much work can hurt your grades. Aim for no more than 15-20 hours per week during the school year to maintain academic focus.

Private Loan Pressure Some colleges or loan servicers may suggest private loans easily accessible. Resist this. Max out federal loans first—they're designed for your protection and have better terms.

FAQ

Q: Do I need to take out loans to pay for college?

A: Not always. About 50% of college costs are covered through free money (grants and scholarships) on average, and another chunk through work-study and family contributions. Loans are only necessary if these sources don't cover the full cost. However, many families do need some loans to bridge the gap.

Q: What if my family's income is too high for need-based aid?

A: You may not qualify for need-based federal grants like the Pell Grant, but you can still take federal student loans (not need-based) and pursue merit scholarships. Also explore state and institutional scholarships, which may not be need-based. Many families earning above average incomes still qualify for some college aid.

Q: When should I apply for scholarships?

A: Start early—as early as 9th grade. Some scholarships are available to high school students, and many colleges award merit scholarships based on admission applications. The priority is the FAFSA (submit it as soon as it opens October 1st), then scholarship searches throughout fall and spring.

Q: Can I borrow federal loans without completing the FAFSA?

A: No. Federal student loans require FAFSA completion. Complete it even if you don't think you'll qualify for grants—you may be eligible for loans and work-study.

Q: Are parent PLUS loans a good idea?

A: PLUS loans carry higher interest rates than undergraduate federal loans. Parents should first check whether their student has exhausted their federal loan eligibility. If additional borrowing is necessary, PLUS loans are better than private loans, but explore all other options first.

Q: What happens if I don't repay my student loans?

A: Federal student loans will go into default, damaging your credit and opening you to wage garnishment and legal action. Federal loans offer repayment plans and hardship options—use these before letting a loan default. Private loans have few protections and can be even more serious.
