An unsub loan, short for Direct Unsubsidized Loan, is a federal student loan available to undergraduate, graduate, and professional students regardless of financial need. Unlike subsidized loans, where the government covers interest while you’re in school, an unsubsidized loan starts accruing interest the moment it’s disbursed. That distinction is the single most important thing to understand about this loan type, because it directly affects how much you’ll owe by the time you start making payments.
Who Qualifies
Eligibility for an unsubsidized loan is broad. You need to be enrolled at least half-time at a school that participates in the Direct Loan Program, and you generally need to be pursuing a degree or certificate. There’s no income test, no credit check, and no requirement to demonstrate financial need. That’s what makes it different from a subsidized loan, which is reserved for undergraduates who show financial need based on their FAFSA results.
Because there’s no need-based qualification, nearly every student who fills out the FAFSA and meets basic enrollment requirements will be offered unsubsidized loans as part of their financial aid package. Graduate and professional students are only eligible for unsubsidized loans (not subsidized), so if you’re in law school, medical school, or a master’s program, this is the standard federal loan you’ll be working with.
How Interest Works While You’re in School
This is where unsubsidized loans cost you more than subsidized ones. Interest begins accruing on your unsub loan as soon as the money is sent to your school. If you’re a full-time undergraduate borrowing for four years, that means interest piles up for roughly four years before you ever make a required payment.
You’re not required to pay that interest while enrolled, but ignoring it has a real cost. When your grace period or deferment ends, any unpaid interest gets capitalized, meaning it’s added to your principal balance. From that point forward, you’re paying interest on a larger amount. For example, if you borrowed $20,000 over four years and $4,000 in interest accumulated during school, your new principal becomes $24,000. Every future interest charge is then calculated on that $24,000 figure rather than the original $20,000.
You can avoid capitalization by making interest-only payments while you’re still in school. Even small monthly payments (often under $100 depending on your balance) can prevent your loan from growing before repayment officially begins.
Current Interest Rates
Federal student loan rates are fixed for the life of the loan but change each year for new borrowers. For loans first disbursed between July 1, 2025, and June 30, 2026, the rates are:
- Undergraduate unsubsidized loans: 6.39%
- Graduate and professional unsubsidized loans: 7.94%
These rates are set annually based on the 10-year Treasury note yield, plus a fixed margin set by law. Once your loan is disbursed, your rate stays the same for the entire repayment period regardless of what happens to interest rates in future years. The government also charges a small origination fee, deducted from each disbursement before the money reaches your school.
How Much You Can Borrow
Annual borrowing limits depend on your year in school and whether you’re a dependent or independent student. The limits below cover both subsidized and unsubsidized loans combined, so whatever portion you receive in subsidized loans reduces the unsubsidized amount available to you.
Dependent Undergraduates
- First year: $5,500 total ($3,500 max in subsidized)
- Second year: $6,500 total ($4,500 max in subsidized)
- Third year and beyond: $7,500 total ($5,500 max in subsidized)
In practice, if you qualify for the maximum subsidized amount as a first-year dependent student ($3,500), the remaining $2,000 of your $5,500 limit would come as an unsubsidized loan.
Independent Undergraduates
- First year: $9,500 total ($3,500 max in subsidized)
- Second year: $10,500 total ($4,500 max in subsidized)
- Third year and beyond: $12,500 total ($5,500 max in subsidized)
Independent students get significantly higher limits because they can’t rely on parental support. Dependent students whose parents are denied a Direct PLUS Loan also qualify for these higher amounts.
Graduate and Professional Students
Graduate students can borrow up to $20,500 per year in unsubsidized loans. Since graduate students are no longer eligible for subsidized loans, the entire amount is unsubsidized.
Lifetime Aggregate Limits
There’s also a cap on total federal loan borrowing across all years of school. Dependent undergraduates can borrow up to $31,000 in combined subsidized and unsubsidized loans over their entire undergraduate career. Independent undergraduates can borrow up to $57,500. Graduate and professional students have an aggregate limit of $138,500, which includes any undergraduate federal loans.
When Interest Capitalizes
Capitalization doesn’t happen continuously. It’s triggered by specific events, and knowing when it occurs helps you plan around it. For unsubsidized loans held by the Department of Education, interest capitalizes when a deferment period ends. It also capitalizes in certain situations tied to income-driven repayment plans: if you voluntarily switch to a different repayment plan, miss your annual income recertification deadline, or no longer qualify for reduced payments after recertification.
Each capitalization event increases your principal balance and raises the cost of your loan over time. If you’re on an income-driven plan, staying on top of your annual recertification paperwork is one of the simplest ways to avoid unnecessary capitalization.
How to Get an Unsubsidized Loan
You apply by submitting the FAFSA (Free Application for Federal Student Aid). Your school’s financial aid office then determines how much you’re eligible to borrow and includes unsubsidized loans in your aid offer. You can accept the full amount offered or choose to borrow less.
Before your first disbursement, you’ll need to complete entrance counseling, an online session that walks you through your responsibilities as a borrower, and sign a Master Promissory Note, which is your legal agreement to repay. Both steps are done on the Federal Student Aid website and take about 30 minutes total. Once those are complete, the loan funds are sent directly to your school and applied to tuition, fees, and room and board. Any remaining balance is refunded to you.
After you graduate, leave school, or drop below half-time enrollment, you get a six-month grace period before repayment begins. Interest continues to accrue during this grace period and capitalizes when repayment starts, so again, making payments during those six months can save you money over the life of the loan.
