How Student Loan Interest Works
Understand the true cost of borrowing
To finance your college education, you may be considering student loans, or perhaps you’re already looking over your award letter. When weighing different loan options, consider the interest rate you’ll pay on your student loan. Regardless of the loan type, part of the total cost will be the interest accrued over your repayment period.
Due to the economic fallout of COVID-19, the government enacted a law on March 27 waiving interest on federal student loans for six months.
But there are different loan interest structures depending on your loan provider, whether you’re an undergrad or grad student, and your credit history. And no matter how you pay interest, some of it may be tax-deductible. Here’s what to know about different kinds of student loan interest.
Fixed Interest Rate Student Loans
A fixed interest rate basically means that your interest rate won’t change while you’re in school, or while repaying your loan. For the period of July 1, 2019, through July 1, 2020, interest rates for federal Direct Subsidized, Direct Unsubsidized, and Direct PLUS student loans are between 4.53% to 7.08%.
Your rate depends on whether you’re an undergraduate or graduate student, and whether or not the loan is subsidized. Additionally, fixed rates differ for Direct PLUS loans and standard Direct student loans.
However, a private lender’s fixed rate may include factors such as your credit history, course of study, and your college or university, which federal loans don’t rely upon.

Private student loan lender interest rates may depend on your credit history, so ensure it’s in good shape
Variable Interest Rate Student Loans
Variable interest rates are primarily offered by private lenders and can fluctuate over the life of your loan, in step with an index rate—much like an adjustable-rate mortgage. As a result, your payments vary if the interest rate goes up or down.
Federal student loans don’t have variable interest rates, unless your loan originated before July 1, 2006.
Offered by private student loan lenders
Potentially offers low interest rates, depending on the index rate
Rates may be lower than those for federal loans
Interest rates can rise
Not offered by the federal lending apparatus
Interest rate changes make it challenging to plan for long-term payments
Subsidized Student Loans
Subsidized loans are offered to undergraduate students demonstrating financial need, and allow you to put off payments until you’ve finished school. Financial need is defined as the difference between a school’s cost of attendance and your expected family contribution (EFC), according to the U.S. Department of Education.
The U.S. Department of Education subsidizes (or pays) your interest while you’re attending school at least half-time and during the grace period, which is the first six months after you leave school, whether graduating, quitting school, or enrolling below half time.
Available to those demonstrating need

You don’t need to pay interest if you go into deferment, or during certain periods within select repayment plans
Not available to students who don’t demonstrate a financial need
Not available to graduate students
Undergraduates are capped at $23,000 as a lifetime total
Unsubsidized Student Loans
Federal unsubsidized loans are offered to all students, independent of financial need, often to supplement subsidized loans. Your university considers your financial aid needs and the cost of attendance when awarding unsubsidized loans.
You’re responsible for paying interest on unsubsidized loans at all times. You could defer interest while in school, during the grace period, or during deferment, but it will still accrue and be added to your principal when you start making payments.
Available to all students, not just those showing financial need
You can defer interest while in school and during grace periods
Available to graduate students
Interest rate lower than the PLUS loan interest rate
Unpaid interest begins accruing during school and grace periods

Graduate unsubsidized loans have a higher interest rate than undergraduate loans
Student Loans With Grace Periods
Most federal loans offer a six-month grace period, except Direct PLUS loans, which are primarily for parents and graduate students and have no grace period. Most private student loans don’t offer grace periods but check with your lender to see if it’s offered.
Your grace period may be extended if you’re called to active duty military or return to school before your grace period ends. Your grace period may end early if you consolidate your loans.
The Bottom Line: Reducing Student Loan Interest Costs
The total student loan repayment amount depends on the type of loan, total loan amount, loan interest rate, duration of the repayment period, and your chosen repayment plan. That said, there are still a few options that may help you save money on student loan interest:
- Accept subsidized loans before turning to unsubsidized loans.
- Shop around for a private student loan interest rate that works for your budget.
- The sooner you can repay the loan, the less interest will accrue. If you are financially able, try paying all of your interest–or toward your interest–while you’re in school.
- Ask your student loan servicer whether you can receive an interest-rate reduction if you enroll in autopay, make all payments on time, and if any other discounts are available.
- After you graduate, paying off your student loans on a faster timetable decreases the total amount you end up paying (although your payments will be higher).
Refinance your student loan to get a better interest rate or consolidate your student loans to bring down the average rate.
