Understanding federal loan interest rates

Everything you need to know about federal student loan interest rates

Federal student loans continue to be the most common form of student borrowing. Offered by the U.S. government with interest rates set by federal law, and with a variety of repayment options, federal student loans can be a competitive way to pay for college.

That said, it’s important to understand how they work to find out if they are the right option for you.

What is federal student loan interest?

Interest is the cost of borrowing money from a lender; an interest rate is the percentage charged to borrow that money. It’s calculated as a percentage of the unpaid principal (i.e., the remaining balance) of the loan. That’s why it’s important to understand how much you’ll be charged for interest.

Money borrowed through federal student loans will ultimately need to be paid back with interest—unless you’re borrowing Direct Subsidized Federal Loans, which have such benefits like the government paying interest on the loan while you’re in school. These loans are needs-based and aren’t available to everyone.

What are the interest rates for federal student loans?

Federal student loan interest rates are reviewed and determined based on 10-year Treasury notes, plus a fixed rate of interest. They’re reset on July 1 of every year. Rates are set by federal law (not the Department of Education). Federal student loans only offer fixed interest rates, which means your rate never varies and you’ll have a predictable monthly payment.

Here are the current interest rates for federal student loans first disbursed on or after July 1, 2024, and before July 1, 2025:

- Direct Subsidized Loans (Undergraduate): These loans currently have a fixed interest rate of 6.53% and are only offered to those undergraduate students who’ve demonstrated financial need as defined by federal law. The government pays interest on the loan while the undergraduate student is in school at least half-time, during deferment (a period when loan payments are temporarily postponed), or during the grace period (typically the first six months after leaving school).

- Direct Unsubsidized Loans (Undergraduate): These loans share the same fixed interest rate as Direct Subsidized Loans, 6.53%, but are not based on financial need. The government does not pay the interest on Direct Unsubsidized Loans, so you’re responsible for all of it.

- Direct Unsubsidized Loans (Graduate/Professional): These loans are available for graduate or professional students at a current fixed interest rate of 8.08%. Similar to their undergraduate counterpart, the government does not cover the interest on Direct Unsubsidized Loans.

- Direct PLUS Loans: These loans are unsubsidized, credit-based federal loans for parents of dependent students—or graduate/professional students—and have a current interest rate of 9.08%. Interest for these loans is charged throughout all periods of the loan.

Federal student loans vs private student loans

Just as the government offers federal student loans, banks and credit unions offer private student loans. These also charge interest (which you’ll have to pay back).

Unlike federal loans, which only offer fixed interest rates, most private student loans offer a choice of fixed or variable rates. Another difference is that private student loans generally require a credit check. That means the lender will review your credit history to make sure you can pay back the loan. If you haven’t had time to establish credit (many college students haven't), you may need to add a cosigner—someone with good credit who will be responsible along with you for the loan. 

Generally, federal student loans have more flexible repayment plans available, so consider using those before you turn to a private student loan.
