Most graduate students can borrow up to $20,500 per year through federal Direct Unsubsidized Loans, then close any remaining gap with a Grad PLUS loan up to the school’s full cost of attendance. Federal graduate school loan limits also carry a $138,500 lifetime ceiling on unsubsidized borrowing for most programs, with higher caps for health professions students and a new, separate track for professional degree students starting July 1, 2026. Whatever the loan rules allow on paper, your school’s certified cost of attendance is the ceiling that overrides everything else.
The $20,500 Annual Unsubsidized Loan Cap
The Direct Unsubsidized Loan is the core federal option for graduate students, and the annual limit is $20,500.1eCFR. 34 CFR 685.203 – Loan Limits The regulation stacks an $8,500 base with an additional $12,000 that only graduate and professional students can access. Your income and financial need don’t change the number. You do need to file the FAFSA every year to qualify.2Federal Student Aid. Eligibility Requirements
One thing to plan around: graduate students are not eligible for subsidized loans. The Budget Control Act of 2011 ended graduate subsidized eligibility as of July 1, 2012, so interest starts accruing the day your loan is disbursed.3Federal Student Aid. Elimination of Subsidized Loan Eligibility for Graduate Students When you enter repayment, any unpaid interest capitalizes onto your principal.4Federal Student Aid. Direct Subsidized and Direct Unsubsidized Loans
Grad PLUS Fills the Gap Up to Cost of Attendance
When $20,500 isn’t enough, the Grad PLUS loan covers the rest. It has no fixed dollar cap. You can borrow up to your school’s cost of attendance minus any other financial aid you’ve received for the year.5Office of the Law Revision Counsel. 20 USC 1078-2 – Federal PLUS Loans For a student in a $70,000-per-year program who receives $5,000 in grants and takes the full $20,500 in unsubsidized loans, the Grad PLUS ceiling for that year would be $44,500.
The catch is a credit check. The Department of Education will deny a Grad PLUS loan for what the regulations call adverse credit history: debts over $2,085 that are at least 90 days delinquent or in collections within the past two years, or a bankruptcy discharge, foreclosure, or tax lien within the past five years.6eCFR. 34 CFR 685.200 – Borrower Eligibility
If you’re denied, you can add an endorser who passes the same credit review, or appeal by documenting extenuating circumstances such as credit reporting errors or identity theft. Either route requires PLUS loan counseling before the loan can be processed.7Federal Student Aid. PLUS Loans: What to Do if You’re Denied Based on Adverse Credit History Grad PLUS also uses a separate Master Promissory Note from the one covering your Unsubsidized Loans.8Federal Student Aid.

The $138,500 Lifetime Cap
Federal borrowing carries a lifetime ceiling that combines everything you’ve taken out for both undergraduate and graduate school. For most graduate students, that combined total maxes out at $138,500, and within that amount no more than $65,500 can come from subsidized loans left over from your undergraduate years.1eCFR. 34 CFR 685.203 – Loan Limits
The math is direct: subsidized debt from undergrad counts against both the $65,500 subsidized cap and the overall $138,500. If you finished undergrad with $30,000 in subsidized loans, you have $108,500 of federal room left, all of which would be unsubsidized. Once you hit the cap, you can’t take out additional federal student loans until your outstanding principal drops below the limit.
Grad PLUS is different. It has no aggregate cap of its own beyond the annual cost-of-attendance cutoff, so a graduate student who exhausts the unsubsidized aggregate can keep borrowing through Grad PLUS as long as the credit check clears each year.
Higher Limits for Health Professions Students
Students in certain health-related programs qualify for substantially higher annual and lifetime amounts. A first tier adds an additional $20,000 per nine-month academic year on top of the $20,500 base, for an annual total of $40,500. It covers allopathic medicine, osteopathic medicine, dentistry, veterinary medicine, optometry, podiatric medicine, and naturopathic medicine.9Federal Student Aid. Annual and Aggregate Loan Limits
A second tier adds $12,500 per year instead, for a $33,000 annual total. This group includes pharmacy, public health (master’s or doctoral), chiropractic, doctoral clinical psychology, and health administration (master’s or doctoral).9Federal Student Aid. Annual and Aggregate Loan Limits Programs longer than nine months prorate the extra amounts upward, so a 12-month first-tier program allows an additional $26,667 rather than $20,000.
The aggregate lifetime cap for health professions students eligible for these amounts is $224,000 rather than $138,500, still with no more than $65,500 in subsidized undergraduate loans. The extra health professions borrowing also doesn’t count against your regular aggregate limit if you later enroll in a different type of program.9Federal Student Aid. Annual and Aggregate Loan Limits
New Professional Degree Limits Beginning July 2026
The One Big Beautiful Bill Act, signed July 4, 2025, created a separate borrowing category for professional degree students. For enrollment periods beginning on or after July 1, 2026, professional students can borrow up to $50,000 per year in Direct Unsubsidized Loans, with a $200,000 aggregate cap.10Federal Register. Reimagining and Improving Student Education The Department of Education is finalizing the implementing regulations.
The definition of “professional student” is expected to cover law, medicine, dentistry, pharmacy, veterinary medicine, optometry, osteopathic medicine, podiatry, chiropractic, clinical psychology, and theology.10Federal Register. Reimagining and Improving Student Education For a law student, that changes the picture considerably: instead of $20,500 in unsubsidized plus whatever Grad PLUS covers, the annual unsubsidized amount alone jumps to $50,000. Because the regulations are still being written, check with your school’s financial aid office for how the rules will apply to your program.
Cost of Attendance Is the Real Ceiling
Every number above is theoretical until your school certifies it. Federal law requires each institution to calculate a comprehensive annual budget for you that covers tuition, required fees, housing, food, books, supplies, transportation, and personal expenses.11Office of the Law Revision Counsel. 20 USC 1087ll – Cost of Attendance That figure functions as a hard ceiling for all financial aid combined, federal and private.
If your cost of attendance is $55,000 and you’ve received $15,000 in grants and scholarships, your total borrowing that year cannot exceed $40,000 regardless of what individual loan limits would otherwise allow. Two students in the same program at different schools may face different borrowing maximums because their institutions calculated different budgets based on local housing costs and fees.
If your actual expenses run higher than the standard budget, your financial aid office has the authority to increase your cost of attendance for documented special circumstances. Childcare and disability-related expenses are the most common approved reasons.12Office of the Law Revision Counsel. 20 USC 1087tt – Discretion of Student Financial Aid Administrators You submit documentation and request the adjustment directly through your school. Many students don’t realize the budget is negotiable when circumstances warrant it.
What You Actually Receive: Rates and Origination Fees
Limits tell you the ceiling. Rates and fees tell you what the loans cost and how much cash lands in your account.
For loans first disbursed between July 1, 2025, and June 30, 2026, graduate Direct Unsubsidized Loans carry a fixed rate of 7.94%. Grad PLUS loans are higher at 8.94%.13Federal Student Aid. Interest Rates and Fees for Federal Student Loans Both rates are fixed for the life of the loan. New rates are set each year based on the 10-year Treasury note auction in May, so loans disbursed after July 1, 2026, will carry a different rate that won’t be known until then.
The government also deducts an origination fee from each disbursement before you get the money. For loans disbursed between October 1, 2025, and September 30, 2026, that fee is 1.057% for Direct Unsubsidized Loans and 4.228% for Grad PLUS.13Federal Student Aid. Interest Rates and Fees for Federal Student Loans Borrow $20,500 in unsubsidized and roughly $217 comes off the top. Borrow $30,000 in Grad PLUS and the fee takes about $1,268. You still owe the full amount you borrowed. You just receive less.
The Grad PLUS origination fee is the number most borrowers overlook. At 4.228%, a student taking $40,000 in PLUS loans each year over three years of law school loses more than $5,000 to fees alone.
When Federal Loans Aren’t Enough: Private Loans
Private lenders step in when federal borrowing doesn’t cover the bill or when you want different terms. Banks, credit unions, and online lenders set their own caps based on your creditworthiness rather than federal rules. Many will lend up to the school’s full cost of attendance, and some impose their own aggregate limits that vary by lender and field.
Terms vary widely. Rates can be fixed or variable and depend heavily on your credit score and income, or your co-signer’s. A borrower with strong credit may find rates below the 7.94% or 8.94% federal rates, while a borrower without a solid credit history will likely see higher rates or a denial. Most private lenders require a co-signer for current students who lack independent income.
The cost-of-attendance ceiling still applies. A private lender willing to approve more cannot disburse funds that push your total aid above the school-certified budget. And private loans don’t offer income-driven repayment plans, federal forgiveness programs, or the automatic in-school deferment that comes with federal borrowing. For graduate students entering lower-paying fields, that gap in repayment flexibility often matters more than the rate comparison.
