A federal student loan is money you borrow directly from the U.S. government to pay for college or graduate school. Unlike private loans from banks or credit unions, federal student loans come with fixed interest rates set by law, access to income-driven repayment plans, and potential loan forgiveness. There are three main types, each designed for different borrowers and situations.
Direct Subsidized Loans
Direct Subsidized Loans are available only to undergraduate students who demonstrate financial need. “Financial need” here means the gap between what your school costs and what you and your family can afford to contribute, as calculated from your federal aid application.
The biggest advantage of a subsidized loan is that the government pays the interest while you’re enrolled at least half-time, during your six-month grace period after leaving school, and during any approved deferment (a temporary pause on payments). That means your balance doesn’t grow while you’re still in class. For loans first disbursed between July 1, 2025, and June 30, 2026, the interest rate is 6.39%, and it stays fixed for the life of the loan.
Your school determines how much you can borrow in subsidized loans each year, and the amount can’t exceed your financial need. Annual limits for dependent undergraduates range from $3,500 for first-year students up to $5,500 for third-year students and beyond, with a lifetime cap of $23,000 in subsidized borrowing.
Direct Unsubsidized Loans
Direct Unsubsidized Loans are open to undergraduates, graduate students, and professional students regardless of financial need. You don’t have to prove a gap between cost and family resources to qualify. Your school still sets the loan amount based on your cost of attendance minus other aid you receive.
The trade-off for broader eligibility is that you’re responsible for all interest from the day the loan is disbursed. If you don’t pay the interest while you’re in school, during deferment, or during forbearance (another type of payment pause), it accrues and eventually capitalizes. Capitalization means the unpaid interest gets added to your principal balance, so you end up paying interest on a larger amount going forward.
For the 2025-26 disbursement year, the rate is 6.39% for undergraduate borrowers and 7.94% for graduate and professional students. Both rates are fixed for the life of the loan.
Direct PLUS Loans
Direct PLUS Loans serve two groups: parents borrowing on behalf of dependent undergraduate children (Parent PLUS) and graduate or professional students borrowing for their own education (Grad PLUS). PLUS loans allow borrowing up to the full cost of attendance minus any other financial aid, so they can cover larger gaps than subsidized or unsubsidized loans alone.
PLUS loans carry a higher interest rate. For loans disbursed between July 1, 2025, and June 30, 2026, the rate is 8.94%. They also require a credit check. You won’t need a specific credit score, but the Department of Education will look for adverse credit history such as recent defaults, foreclosures, or bankruptcies. If you’re denied, you can still qualify by obtaining an endorser (essentially a co-signer) or by documenting extenuating circumstances.
Interest Rate Caps
Federal student loan rates reset each year based on the 10-year Treasury note yield, but they can never exceed a statutory ceiling. For undergraduate subsidized and unsubsidized loans, the cap is 8.25%. For graduate unsubsidized loans, it’s 9.50%. For PLUS loans, it tops out at 10.50%. Once your loan is disbursed at a given rate, that rate is locked in permanently, even if rates rise the following year.
How to Apply
Every federal student loan starts with the FAFSA, the Free Application for Federal Student Aid. You’ll need to create a Federal Student Aid (FSA) ID, which serves as your electronic signature, and then fill out the form at fafsa.gov. The application asks about your family’s income, assets, and household size. If you’re a dependent student, a parent will also need their own FSA ID to contribute their financial information.
For the 2025-26 school year, the federal deadline to submit the FAFSA is June 30, 2026, but many schools and states set earlier deadlines for their own aid programs. Submitting early gives you the best shot at all available funding. After you submit, you’ll receive a summary report. Review it carefully and correct any errors before the due date listed on the report. If you submit a paper form, allow 7 to 10 days before checking your status online.
Once your FAFSA is processed, your school will send you a financial aid offer showing the types and amounts of aid you qualify for. You can accept, reduce, or decline each loan separately. You don’t have to take the full amount offered.
Repayment Plans
After you graduate, drop below half-time enrollment, or leave school, you typically get a six-month grace period before payments begin. From there, the standard repayment plan spreads your balance over 10 years of fixed monthly payments. But several other options exist if that monthly amount is too high.
Income-driven repayment (IDR) plans set your monthly payment as a percentage of your discretionary income, which can significantly lower what you owe each month. Starting July 1, 2026, the Department of Education is introducing two new options. The Repayment Assistance Plan (RAP) bases payments on income and number of dependents, with built-in protections against runaway interest so that borrowers making full, on-time payments see their principal balance decrease over time. The Tiered Standard Plan offers fixed repayment terms of 10, 15, 20, or 25 years depending on your total balance, giving borrowers with higher debt more time and smaller monthly payments.
Borrowers who were previously enrolled in the now-discontinued SAVE Plan will receive notices from their loan servicers starting July 1, 2025, with instructions to select a new repayment plan within 90 days. Those who don’t choose will be automatically placed into either the Standard Repayment Plan or the new Tiered Standard Plan.
Loan Forgiveness
Federal loans offer forgiveness pathways that private loans almost never do. The most established is Public Service Loan Forgiveness (PSLF), which cancels your remaining balance after 120 qualifying monthly payments (10 years) while working full-time for a qualifying employer. Qualifying employers include government agencies at any level, nonprofits with 501(c)(3) status, and certain other public service organizations. You must be on an income-driven or other qualifying repayment plan for your payments to count.
Income-driven repayment plans also carry their own forgiveness timeline. Any remaining balance is typically forgiven after 20 or 25 years of qualifying payments, depending on the plan and loan type. The forgiven amount may be treated as taxable income in some cases, unlike PSLF forgiveness, which is tax-free.
Why Federal Loans Differ From Private Loans
Federal student loans come with protections that private lenders generally don’t match. Interest rates are fixed by law, so your rate never changes over the life of the loan. Private lenders may offer variable rates that start lower but can climb unpredictably. Federal loans offer deferment and forbearance options if you hit financial hardship, lose your job, or return to school. Private lenders may offer limited forbearance, but it varies by lender and isn’t guaranteed.
Subsidized federal loans have no equivalent in the private market. No private lender will cover your interest while you’re in school. Federal loans also don’t require a credit history for subsidized and unsubsidized borrowing (PLUS loans are the exception), making them accessible to 18-year-olds with no credit profile. Private loans almost always require a creditworthy co-signer for younger borrowers.
For these reasons, federal loans are generally the first borrowing option to exhaust before turning to private lenders. Your financial aid offer will tell you exactly how much federal borrowing you qualify for, and you can fill any remaining gap with private loans, scholarships, or other funding.
