Federal loans come with protections most private loans do not.

For many students, loans are part of paying for college. Borrowing isn't automatically bad — but borrowing without understanding the terms can lead to years of stress. Federal student loans are usually the safest place to start because they come with fixed interest rates, flexible repayment options and borrower protections. This guide explains how they work in plain language.

Why federal loans come first

Compared with private loans from banks, federal student loans offer:

  • Fixed interest rates set by law each year, the same for every borrower regardless of credit.
  • No credit check for student Direct Loans and no co-signer needed.
  • Income-driven repayment options that tie payments to what you earn.
  • Deferment and forbearance options if you face hardship.
  • Forgiveness programs such as Public Service Loan Forgiveness.

Use grants, scholarships, savings and work first. Then use federal loans. Consider private loans only as a last resort.

Types of federal loans for undergraduates

Direct Subsidized Loans

Available to undergraduates with financial need. The government pays the interest while you're enrolled at least half-time, during your six-month grace period after leaving school, and during approved deferment. This makes them the least expensive loan option.

Direct Unsubsidized Loans

Available to undergraduates and graduate students regardless of need. Interest starts building from the day the money is paid out. If you don't pay the interest while in school, it's added to your balance later, so you'll pay interest on interest.

Parent PLUS Loans

Parents of dependent undergraduates can borrow to help cover costs. These loans require a credit check for adverse credit history and typically carry higher interest rates and fees. For new borrowers, federal law now caps Parent PLUS borrowing per student, so check StudentAid.gov for current limits before relying on these loans.

How much can you borrow?

YearDependent studentsIndependent students*
First year$5,500 (up to $3,500 subsidized)$9,500 (up to $3,500 subsidized)
Second year$6,500 (up to $4,500 subsidized)$10,500 (up to $4,500 subsidized)
Third year and beyond$7,500 (up to $5,500 subsidized)$12,500 (up to $5,500 subsidized)
Total limit$31,000 (up to $23,000 subsidized)$57,500 (up to $23,000 subsidized)

*Higher limits also apply to dependent students whose parents can't get a Parent PLUS Loan.

You don't have to accept the full amount offered. You can accept part of a loan, or decline it entirely.

Interest rates and fees

Federal loan interest rates for new loans are set each year and stay fixed for the life of that loan. Federal loans also have an origination fee, a small percentage deducted from each disbursement. Look up the current rates and fees on StudentAid.gov before you accept.

How to get a federal loan

  1. File the FAFSA.
  2. Review your college's financial aid offer to see which loans you're eligible for.
  3. Accept the amount you need through your college's financial aid portal.
  4. Complete Entrance Counseling and sign a Master Promissory Note (MPN) on StudentAid.gov.
  5. The loan is paid directly to your college to cover tuition and fees. Any leftover money is refunded to you for other education expenses.

How much should you borrow?

  • Borrow only what you need to cover your actual remaining costs.
  • Estimate future earnings. A common guideline is to keep total student debt below your expected first-year salary. The College Scorecard shows typical earnings by college and major.
  • Calculate your monthly payment using the loan simulator on StudentAid.gov.
  • Pay interest while in school on unsubsidized loans if you can — even small payments reduce what you'll owe.

Private student loans: proceed carefully

Private loans come from banks, credit unions and online lenders. Rates may be variable and depend on credit, often requiring a co-signer. They usually lack income-driven repayment and federal forgiveness. If you must use them, compare several lenders, choose a fixed rate if possible, and borrow the minimum.

Keep track of your loans

Log in to StudentAid.gov to see all your federal loans, balances and your loan servicer — the company that will handle your payments. Keep a simple record each year of what you borrowed. Knowing your total helps you make smarter decisions every semester.
