Before any other borrowing conversation, federal student loans should be the first option exhausted. Federal undergraduate loans carry standardized interest rates set annually by Congress, income-driven repayment options that adjust payments to what a borrower actually earns, deferment and forbearance provisions for financial hardship, and in specific programs, loan forgiveness after sustained repayment.

The Project on Predatory Student Lending is direct about the comparison: private loans are usually more expensive and always less flexible than federal loans. Private loans typically have fewer repayment options, no income-driven safety net, and no forgiveness pathway. For undergraduate students, the annual federal loan limits — $5,500 to $7,500 per year depending on year in school — apply regardless of school cost. Maxing out federal loans before turning to any other source is standard financial planning advice from virtually every college finance resource.

If the school requires borrowing beyond what federal student loans can cover, the next category is Parent PLUS loans — federal loans taken out by parents rather than students. These carry higher interest rates than student loans (8.05% for 2023-24 disbursements, compared to 5.5% for student loans in that year), require immediate repayment without the six-month post-graduation grace period that student loans provide, and have no cap relative to the cost of attendance.

Parent PLUS loans are one of the most misunderstood instruments in college finance. They are federal loans in the parent's name, not the student's. Repayment is the parent's legal obligation — and Fastweb, NerdWallet, and the Project on Predatory Student Lending all emphasize that informal arrangements where the student agrees to repay the PLUS loan don't change the legal borrower of record.

Parent PLUS loans have no annual or aggregate borrowing limit relative to income. Parents can borrow up to the full cost of attendance minus other aid, regardless of their income, retirement proximity, or other financial obligations. NerdWallet's guidance includes a checklist of questions parents should ask before borrowing: Can you save for retirement and pay down other debts while making PLUS payments? Will your income remain steady for the length of the repayment? Would you still be able to cover your own financial obligations if the arrangement with your child to help with payments doesn't materialize?

The Brookings Institution noted in 2025 that among parents of students at private nonprofit colleges, 19.7% borrow PLUS loans averaging $56,730 — a level that many parents carry into retirement age. The Center for Responsible Lending has documented cases of Parent PLUS borrowers having Social Security payments garnished in default. These are not hypotheticals; they are documented outcomes for borrowers who took on more than their income could support.

One of the most important things families can do before committing to any borrowing level is convert the loan balance to a monthly payment and compare it to actual monthly income. Most families focus on the total amount borrowed without clearly visualizing what that means as a monthly obligation for ten years.

At the federal direct loan rate of 6.52% for loans disbursed starting July 1, 2026, here are rough monthly payments by loan balance on a 10-year standard plan: $30,000 → approximately $341/month; $50,000 → approximately $568/month; $75,000 → approximately $852/month; $100,000 → approximately $1,137/month. These payments don't pause when the graduate is between jobs, paying rent for the first time, or managing a car payment and health insurance.

For parent borrowing, the payment timeline starts immediately after disbursement rather than after graduation. A parent borrowing $60,000 in PLUS loans over four years while simultaneously paying for tuition, maintaining their own household, and ideally saving for retirement is managing multiple financial obligations at once. Building the monthly payment into a family budget simulation before borrowing — rather than after — is one of the most practical financial planning steps available.

Fastweb advises that families have frank conversations before borrowing about who is legally responsible for what debt, and who will actually be making payments after graduation. This conversation is uncomfortable, but it's significantly less uncomfortable than having it after a student graduates and the payment notices start arriving.

Specific questions worth addressing before any loan is signed: Who is the legal borrower on each loan, and whose credit and income are at stake if payments are missed? If the student plans to help repay Parent PLUS loans, what is the plan if they are unemployed, in a low-paying job, or face a medical emergency? What income does the parent need to maintain in retirement to cover both their own costs and any remaining loan payments? Is the school and major combination likely to produce a starting salary that supports repayment on the student's own borrowing?

NerdWallet's guidance for parents considering PLUS loans is worth repeating: "Unless you carefully consider whether you can bear the burden of that debt, that choice to take out a parent PLUS loan could haunt you for years and threaten your financial security for decades." That's not alarmism — it's a description of documented outcomes for families who borrowed more than their income could support.

Borrowing for college is a reasonable and often necessary financial decision. But the terms of what's being borrowed — who owes it, what the monthly payment will be, what happens if repayment becomes difficult — deserve as much attention as the college decision itself. Federal loans first. Clear understanding of PLUS loan risks before a parent signs. A realistic look at what the monthly payment will mean for both student and parent finances in the first years after graduation. Those three steps won't make the decision easy, but they'll make it informed.
