When politicians talk about the student loan crisis, they almost always mean undergraduate debt: the 22-year-old with $35,000 in loans from a state school who can’t find a job that covers the payment. That borrower is real. But the faster-growing, less-discussed part of the crisis is graduate school, where federal loan limits effectively don’t exist, interest rates are higher, and the borrowed amounts regularly reach six figures before the degree is even finished.
Master’s degree borrowers carry an average of $81,870 in total student loan debt, with $64,440 coming from the graduate program alone. Professional doctorate borrowers average $213,439. The question that doesn’t get asked enough: did the income attached to these degrees justify what was borrowed?
Undergraduate federal loan limits are relatively strict. Dependent students can borrow a maximum of $57,500 over their entire undergraduate career. Graduate students face a different world. Direct unsubsidized loans cap at $20,500 per year for most graduate programs, with an aggregate limit of $100,000. But Grad PLUS loans allow students to borrow up to the full cost of attendance with essentially no ceiling, after exhausting direct loan limits. A three-year law degree at a private school in a major city can run $300,000 in total cost of attendance. A graduate student can borrow most of that from the federal government.
This isn’t how the undergraduate system works. An 18-year-old choosing a college is limited in how much federal money they can access. A 24-year-old choosing a law school or MBA program faces almost no comparable constraint. The system trusts graduate students to make rational borrowing decisions with amounts that would require underwriting scrutiny in any other lending context.
Graduate borrowers also pay more to borrow. For the 2025-2026 school year, graduate and professional direct loan interest rates sit at 7.94%, compared to 6.39% for undergraduate borrowers. Grad PLUS loans charge even more. On a $200,000 balance at 7.94%, the accruing interest before a borrower even starts repayment is significant enough to push the total balance well past the original amount borrowed by the time the degree is conferred.
Between April 2025 and March 2026, over 4.2 million student loan borrowers defaulted. Graduate borrowers aren’t necessarily the majority of that number, but they represent a disproportionate share of the highest balances. The defaults that make headlines are often six-figure balances from graduate programs, not $30,000 undergraduate loans.
The graduate school debt crisis isn’t uniform. A medical degree at $300,000 in debt comes with a career earning path that, over time, can service that balance. A master’s degree in communications or education at $60,000 to $80,000 in debt often does not. The federal government guarantees loans for both without differentiating based on the earning potential attached to the degree. Schools have no financial skin in the game when their graduates can’t repay. The borrower carries all of the downside risk.
This is the structural problem the undergraduate debate obscures. The question isn’t just whether student loans are too easy to get. It’s whether the programs and institutions on the receiving end of unlimited federal backing are producing returns that justify the debt, and whether anyone in the system is accountable when they don’t.
Direct unsubsidized loans cap at $20,500 per year for most graduate programs, with a $100,000 aggregate limit. However, Grad PLUS loans allow borrowing up to the full cost of attendance after direct loan limits are reached, with no aggregate cap. A graduate student can theoretically borrow several hundred thousand dollars in federal loans over a multi-year program.
