Yes, there are limits on student loans, but the caps depend on the type of loan, your year in school, and whether you’re classified as a dependent or independent student. Federal student loans have firm annual and lifetime borrowing caps set by the government. Private student loans technically have limits too, but they’re set by individual lenders and can reach several hundred thousand dollars. On top of all of this, your school’s cost of attendance acts as a ceiling on total financial aid you can receive in a given year.
Annual Federal Loan Limits for Undergraduates
The federal government caps how much you can borrow in Direct Subsidized and Unsubsidized Loans each academic year. These limits increase as you move through school, and they differ based on your dependency status. Dependent students (typically those under 24 whose parents provide financial support) have lower caps because the government expects parental contribution.
For dependent undergraduates, the annual limits are:
- First year: $5,500 total ($3,500 maximum in subsidized loans)
- Second year: $6,500 total ($4,500 subsidized)
- Third year and beyond: $7,500 total ($5,500 subsidized)
Independent undergraduates, and dependent students whose parents are denied a PLUS loan, can borrow more:
- First year: $9,500 total ($3,500 subsidized)
- Second year: $10,500 total ($4,500 subsidized)
- Third year and beyond: $12,500 total ($5,500 subsidized)
The subsidized portion is the part where the government covers interest while you’re in school at least half-time. If you don’t qualify for subsidized loans, you can still borrow the full combined amount in unsubsidized loans. So a first-year dependent student who isn’t eligible for any subsidized loans can still take out $5,500 in unsubsidized loans.
Lifetime Aggregate Caps
Beyond the annual limits, the federal government also sets a cumulative ceiling on how much you can owe in Direct Loans across your entire education. Once you hit this cap, you can’t borrow any more federal student loans until you pay down some of what you owe.
The aggregate limits break down as follows:
- Dependent undergraduates: $31,000 total, with no more than $23,000 in subsidized loans
- Independent undergraduates: $57,500 total, with no more than $23,000 in subsidized loans
- Graduate and professional students: $138,500 total (including any undergraduate borrowing), with no more than $65,500 in subsidized loans
Graduate students in health professions programs who qualify for increased annual unsubsidized amounts have a higher aggregate cap of $224,000, though the subsidized portion is still capped at $65,500. One important detail: capitalized interest (unpaid interest that gets added to your principal balance) does not count toward these aggregate limits. Only the original loan amounts matter.
Graduate and PLUS Loan Limits
Graduate students have historically had access to Direct PLUS Loans (often called Grad PLUS), which allowed borrowing up to the full cost of attendance minus any other financial aid received. There was no fixed dollar cap, making it possible for graduate students to take on very large balances, especially in programs like law school or medical school.
That changes significantly on July 1, 2026. Legislation passed in 2025 eliminates Grad PLUS loans and replaces them with new unsubsidized Direct Stafford Loans that carry firm annual and aggregate limits. Graduate students will be limited to $20,500 per year with a $100,000 aggregate cap. Professional school students (law, medicine, and similar programs) will have higher limits of $50,000 per year and a $200,000 aggregate cap. This is a major shift that will force many graduate students to rely more on savings, scholarships, or private loans.
For parents of dependent undergraduates, Parent PLUS Loans remain available up to the cost of attendance minus other aid, with no fixed dollar ceiling through the current rules.
Cost of Attendance as a Borrowing Ceiling
Regardless of the specific loan limits, your school’s cost of attendance (COA) acts as an overall cap on the financial aid you can receive. The COA is the school’s estimate of what it costs to attend for one year, including tuition, fees, room and board, textbooks, and certain other expenses. You cannot receive total financial aid, including loans, grants, and scholarships, that exceeds this number.
This means even if your loan limits would allow you to borrow more, you can’t if your other aid already covers most of your COA. Schools are required to calculate COA using specific categories defined by federal law, so they can’t inflate it arbitrarily. If you attend a less expensive school, the COA ceiling may actually be the binding constraint on your borrowing rather than the loan limits themselves.
Private Student Loan Limits
Private student loans work differently. There’s no government-set cap. Instead, each lender establishes its own maximum based on your creditworthiness, income (or your cosigner’s income), and the school-certified cost of attendance. Most lenders will let you borrow up to 100% of the cost of attendance, though some set their own annual or lifetime dollar caps.
Aggregate limits among major private lenders vary widely. Some cap total borrowing at $180,000 or $200,000, while others go as high as $400,000 or even $500,000 for graduate health degrees. A few examples from current lenders: one offers up to $400,000 in lifetime borrowing, another caps undergraduates at $125,000 but allows up to $500,000 for graduate health programs, and several fall in the $180,000 to $225,000 range for undergraduate and standard graduate degrees.
The key difference from federal loans is that approval depends heavily on credit. A student with no credit history and no cosigner may struggle to get approved for any private loan, let alone the maximum. Interest rates on private loans are also typically higher and vary based on your credit profile, unlike the standardized rates on federal loans.
What Happens When You Hit the Limit
If you reach your federal aggregate limit partway through your education, your school’s financial aid office will notify you that you’re no longer eligible for additional federal loans. At that point, your options narrow to private loans, out-of-pocket payments, scholarships, or employer tuition assistance.
You can restore your federal borrowing eligibility by repaying some of your outstanding balance to bring it below the aggregate cap. However, you’d need to actually pay down principal, not just make interest payments. For students who completed one degree and are returning for another, this can become a real constraint, since undergraduate borrowing counts toward your graduate aggregate limit as well.
If you’re approaching these limits, contact your school’s financial aid office early. They can help you understand exactly where you stand and whether you qualify for any adjustments based on your dependency status or enrollment level.
