What Is a Student Loan?

A student loan is money borrowed to pay for college, university, vocational school, or other higher education costs. In the United States, student loans can be used for tuition, room and board, books, supplies, and other education-related expenses. Unlike scholarships or grants, student loans must be repaid with interest after you leave school.

The United States has over $1.7 trillion in outstanding student loan debt, making it one of the largest categories of consumer debt in the country. Understanding how your student loan works is essential to managing it effectively after graduation.

Federal vs Private Student Loans

There are two main categories of student loans available to US borrowers:

• Federal Student Loans: Issued by the US Department of Education. These include Direct Subsidized Loans, Direct Unsubsidized Loans, and PLUS Loans. Federal loans offer fixed interest rates set by Congress, income-driven repayment plans, and forgiveness programs. They should always be considered before private loans.
• Private Student Loans: Issued by banks, credit unions, and online lenders. Interest rates can be fixed or variable and depend on your credit score. Private loans generally have fewer repayment protections than federal loans.

Federal Student Loan Interest Rates for 2026

Federal student loan interest rates are set annually by Congress and tied to the 10-year Treasury note. These exact rates apply to loans first disbursed between July 1, 2025 and June 30, 2026:

• Direct Subsidized Loans (Undergrad): 6.53% fixed
• Direct Unsubsidized Loans (Undergrad): 6.53% fixed
• Direct Unsubsidized Loans (Graduate): 8.08% fixed
• Direct PLUS Loans (Parent & Grad): 9.08% fixed

Private student loan rates vary widely based on your credit score and the lender. They typically range from 4% to 16% APR. Always exhaust federal loan options before considering private loans.

Subsidized vs Unsubsidized Student Loans

Understanding the difference between subsidized and unsubsidized federal loans is important for managing your total debt:

• Subsidized Loans: Available to undergraduate students with demonstrated financial need. The federal government pays the interest while you are in school at least half-time, during the grace period, and during deferment. This means your balance does not grow while you are still studying.
• Unsubsidized Loans: Available to undergraduate and graduate students regardless of financial need. Interest accrues from the day the loan is disbursed, including while you are in school. If you do not pay the interest while in school, it capitalizes — meaning it is added to your principal balance.

Student Loan Repayment Plans in the USA

Federal student loan borrowers have access to several repayment plans:

• Standard Repayment Plan: Fixed monthly payments over 10 years. You pay the least total interest under this plan.
• Graduated Repayment Plan: Payments start lower and increase every two years. Designed for borrowers who expect their income to grow.
• Extended Repayment Plan: Fixed or graduated payments over up to 25 years. Lower monthly payments but more total interest.
• Income-Driven Repayment Plans (IDR): Monthly payments are based on your income and family size. Options include SAVE, PAYE, IBR, and ICR plans. Remaining balances may be forgiven after 20 to 25 years of qualifying payments.

Public Service Loan Forgiveness (PSLF)

Borrowers who work full-time for qualifying government or nonprofit organizations may be eligible for Public Service Loan Forgiveness after making 120 qualifying monthly payments under an income-driven repayment plan. This program can result in the complete forgiveness of remaining federal student loan balances.

How to Manage Student Loan Debt Effectively

• Always exhaust federal loan options before turning to private loans
• Make interest payments while in school to prevent capitalization on unsubsidized loans
• Choose the shortest repayment term you can afford to minimize total interest
• Consider refinancing private student loans if you qualify for a lower rate after graduation
• Enroll in autopay — many lenders offer a 0.25% rate reduction for automatic payments
• Make extra principal payments when possible to pay off the loan faster

Should You Pay Off Student Loans Early?

Paying off student loans early can save you a significant amount of interest. Federal student loans have no prepayment penalties, so you can make extra payments at any time without fees. For private loans, check your loan agreement for prepayment penalties before making extra payments.

However, if your student loan interest rate is low, it may make more financial sense to invest extra money in a retirement account or emergency fund rather than aggressively paying off the loan. Use our student loan calculator to compare different payoff scenarios.

Student Loan Refinancing

Refinancing replaces your existing student loans with a new loan from a private lender, ideally at a lower interest rate. This can reduce your monthly payment and total interest cost. However, refinancing federal loans into a private loan means losing access to federal protections such as income-driven repayment plans, deferment options, and loan forgiveness programs.

Frequently Asked Questions

How much student loan debt is too much?

A common guideline is to borrow no more than your expected first-year salary after graduation. If you expect to earn $50,000 in your first job, try to keep total student loan borrowing below $50,000.

When do I start repaying student loans?

For most federal loans, repayment begins six months after you graduate, leave school, or drop below half-time enrollment. This is called the grace period. Private loan repayment terms vary by lender.

Can student loans be discharged in bankruptcy?

It is very difficult, but not impossible, to discharge student loans in bankruptcy. You must prove "undue hardship," which requires a separate legal proceeding called an adversary proceeding. Very few borrowers successfully discharge student loans through bankruptcy.

What happens if I miss a student loan payment?

Missing a federal student loan payment makes the loan delinquent. After 270 days of non-payment, the loan goes into default, which can result in wage garnishment, tax refund seizure, and severe credit score damage. Contact your loan servicer immediately if you are struggling to make payments — income-driven repayment plans and deferment options are available.
