Average Student Loan Debt by Degree and Major (2026): How Much You’ll Really Owe

Average Student Loan Debt by Degree Level

Debt scales sharply with each credential. The jump from a bachelor’s to a professional doctorate is not linear — it accelerates, because graduate and professional students can borrow up to their full cost of attendance through federal loans, with no annual undergraduate-style cap holding them back.

Here is what borrowers actually owe at each level, using federal debt figures from the U.S. Department of Education’s Office of Federal Student Aid as compiled by the Education Data Initiative, alongside professional-degree data from the AAMC and ABA.

One clarification the semantic matters: the master’s figure of $102,790 is cumulative federal debt for degree holders, meaning it can fold in undergraduate balances. The medical and law figures separate education debt from the total-with-undergrad number, which is why AAMC’s total climbs toward $246,659 once premedical borrowing is added. When you compare offers, confirm whether a quoted average is education-only or cumulative — the two are frequently conflated. Understanding the salary-to-debt rule for borrowing limits helps you judge whether any of these figures is sustainable for your field.

Average Debt by Major: Where the Real Variation Lives

Two graduates can both hold a bachelor’s degree and owe amounts that differ by more than $34,000. The Education Data Initiative, drawing on U.S. Department of Education College Scorecard data, found a $36,905 spread between the most- and least-indebted bachelor’s majors from the 2020 graduating cohort.

Field of study drives this gap because it correlates with program length, the prevalence of private versus public institutions, and — critically — the likelihood of continuing to graduate school. Majors that funnel students toward advanced degrees accumulate debt across multiple credentials.

The pattern to notice: the highest-debt majors cluster in health, education research, and behavioral fields — not, as intuition suggests, in the humanities alone. A doctoral pharmacy graduate borrows more than fourteen times what a doctoral anthropology graduate does. Debt tracks the program’s cost structure and required length far more than its cultural reputation for being “impractical.”

How Debt-to-Income Determines Whether Your Debt Is Manageable

A $200,000 balance is a catastrophe for a public defender and a rounding error for a dermatologist. The number that matters is not the debt itself but its ratio to your first-year salary — the metric lenders and financial planners call debt-to-income.

Consider two real scenarios built from the verified figures above. A law graduate carrying the median $112,500 in law school debt who takes a public-sector job at the roughly $57,500 median public-interest starting salary faces a debt-to-income ratio near 1.96 — nearly two dollars owed for every dollar earned. Education Data Initiative modeling estimates that borrower would need roughly 21.8 years to clear the loans while spending 25% of income on payments.

Now run the private-sector version. A law graduate at a large firm earning the $200,000 median private starting salary against the same $112,500 balance sits at a 0.56 ratio and, following federal repayment guidelines, could clear the debt in about 10.8 years. Identical degree, identical debt, radically different outcome — the variable is the job, not the loan.

Apply the same test to a $29,550 bachelor’s balance. Against a $60,000 starting salary, the 0.49 ratio is comfortably serviceable on a standard 10-year plan. Against a $32,000 salary, the same debt becomes a monthly strain that may push a borrower toward income-driven repayment plans compared by cost. Before you borrow, divide your projected debt by your field’s realistic first-year salary; a ratio above 1.0 is a warning that repayment will dominate your early career.

Medical School vs. Law School Debt: Which Degree Pays Back Faster?

Both credentials routinely produce six-figure balances, but they resolve very differently. Medical school carries the larger sticker — a median $223,130 in education debt for the AAMC’s Class of 2025, split between $210,147 at public schools and $244,964 at private ones. Law school’s median law debt of $112,500 is roughly half that.

Yet the raw balance misleads. Physician salaries, though delayed by years of low-paid residency, climb into the $250,000-plus range across many specialties, giving mature-career doctors debt-to-income ratios well under 1.0. Law outcomes split violently: the roughly half of graduates entering large-firm or corporate roles service their debt comfortably, while public-interest and small-market attorneys can face ratios approaching 2.0.

Medicine also offers a structural repayment advantage. AAMC data shows 57.6% of 2025 medical graduates intend to pursue federal loan forgiveness, and hospital-based employment makes many physicians eligible for PSLF qualification and paperwork pitfalls through nonprofit employers. Lawyers in private practice rarely qualify, narrowing their forgiveness options.

For deeper field-specific planning, compare medical school debt repayment strategies against a law school debt vs lawyer salary analysis before committing to either path.

What Most People Get Wrong About Degree Debt

Borrowers repeatedly make the same avoidable errors, and each one carries a measurable cost. These are the three most expensive.

Mistake one: treating the degree average as your number. The “$29,550 for a bachelor’s” figure is a national average blending four-year public grads with private for-profit grads who borrow far more — for-profit students average around $40,970. The consequence is a borrower who plans around the average and is blindsided by a school-specific reality. The correct action: pull your specific program’s median debt from the College Scorecard, not the national headline.

Mistake two: ignoring interest accrual during school. Graduate and PLUS loans accrue interest from disbursement, and at the 2025–2026 graduate rate of 7.94% (or 8.94% for PLUS), a balance grows meaningfully before the first payment is due. A borrower who assumes the balance is static will owe thousands more than they borrowed at repayment. The correct action: make interest-only payments during school where possible, and understand deferment vs forbearance interest accrual before pausing payments.

Mistake three: defaulting to private loans for the rate. A slightly lower private rate can look attractive, but it forfeits federal protections — income-driven plans, forgiveness eligibility, and generous forbearance. The consequence surfaces years later when a borrower loses a job and has no safety net. The correct action: exhaust federal options first and study the federal vs private student loan cost comparison before signing anything private.

Is a High-Debt Degree Worth It? Conditional Logic by Field

Worth is not a property of the degree — it is a property of the match between debt, salary, and repayment strategy. The verified figures let you reason through it conditionally rather than emotionally.

Borrow the full medical school median of $223,130 if you are committed to completing residency and entering a specialty with strong compensation, because the debt-to-income ratio inverts favorably within a few post-residency years. The math breaks only if you exit medicine early or enter a low-paid subspecialty without a forgiveness plan.

Take on the $112,500 law median only if you have a realistic path to the private-sector salary tier, or you intend to work in qualifying public-interest employment where forgiveness programs by profession and state can erase the balance after 10 years. Absent both, the ratio is unforgiving.

For bachelor’s and master’s borrowers, the test is simpler: keep total debt at or below your expected first-year salary. A $44,554 behavioral sciences balance against a $40,000 starting salary is borderline; the same balance against a $70,000 salary is fine. When the ratio runs high, aggressive payoff strategies ranked by interest saved or a later refinancing savings and what is given up analysis can compress the timeline — but neither fixes a fundamentally mismatched borrow. Graduate borrowers weighing federal PLUS against private options should also review the Grad PLUS vs private loan comparison before maxing out federal borrowing.

How We Researched This Article

This analysis draws exclusively on primary and institutional sources for every debt and rate figure. Degree-level and major-level debt data come from the Education Data Initiative, which compiles federal borrowing figures from the U.S. Department of Education’s Office of Federal Student Aid and the College Scorecard. Professional-degree data come directly from the Association of American Medical Colleges (AAMC) Graduation Questionnaire for the Class of 2025 and the American Bar Association Young Lawyers Division 2024 Student Loan Survey. Federal interest rates were verified against the U.S. Department of Education’s Federal Student Aid rate announcements for the 2025–2026 disbursement year.

Debt figures are reported as medians or averages as labeled; where a source distinguishes education-only debt from cumulative debt including undergraduate borrowing, both are noted to prevent conflation. Debt-to-income ratios and repayment-timeline estimates are modeled calculations, not measured survey outcomes — they apply standard federal repayment assumptions to the verified balance and salary figures and should be treated as illustrative. Salary figures reflect the most recent available medians and will vary by geography, employer, and specialty.

Limitations: major-level data reflects the 2020 graduating cohort, the most recent complete College Scorecard release at publication, so current graduates may borrow somewhat more. National averages mask wide institution-level variation, particularly between public, private nonprofit, and for-profit schools. Primary references include the Education Data Initiative, the Association of American Medical Colleges, the American Bar Association, and Federal Student Aid. Research last conducted July 2026. All figures were verified against named primary sources before publication.
