How Does Student Loan Interest Work While You’re in School?
Table of Contents
While in school, most student loans accrue interest. The main exception to this rule is for those who hold federal Direct Subsidized Loans. While a student is taking classes, the interest on these loans is covered by the U.S. government.
It can be important to understand exactly what type of student loan you have to make sure you understand the terms of the loan and when interest accrues. This, as you might guess, impacts how much you will be paying back.
Read on for a guide to how student loan interest works while you are still in school.
Key Points
• Interest generally accrues during school, except for federal Direct Subsidized Loans, where the government pays the interest while you’re enrolled.
• Unsubsidized federal loans still charge interest, even in school, and that accrued interest can be capitalized (added to your principal).
• PLUS Loans accrue immediately, with interest beginning as soon as the loan is disbursed and continuing during enrollment.
• Private loans usually accrue interest in school, and many lenders will capitalize that interest if you defer payments until after graduation.
• Making interest-only payments during school helps, because it limits capitalization and reduces the total cost of the loan.
Understanding How Federal Student Loan Interest Works
Some federal student loans accrue interest while you’re in school, but others do not. To understand how your interest works, it’s essential to know exactly what type of student loan you have. Each loan type follows its own rules for when interest begins accruing and how it’s handled during enrollment.
Subsidized vs. Unsubsidized Loans
Federal student loans may be subsidized or unsubsidized. The accrued interest on Direct Subsidized Loans is covered by the government while a student is enrolled at least half-time. Direct Subsidized Loans are only available to undergraduate students.
For Direct Unsubsidized Loans, students are responsible for paying the interest that accrues on their student loans. Interest begins accruing as soon as the loan is disbursed, or paid out to the borrower.
You won’t be required to make payments while in-school, but be aware that if you don’t, you may graduate with a higher balance than when you started. That’s because the accrued interest is capitalized on the original balance of the loan. Direct Unsubsidized Loans are available to undergraduate and graduate students.
Direct PLUS Loans are available for graduate students (Grad PLUS Loans) or their parents (Parent PLUS Loans). The interest on these loans begins accruing when the loan is disbursed and continues accruing while the student is enrolled in school. Keep in mind that as of July 1, 2026, Grad PLUS Loans will no longer be available (Parent PLUS Loans will still be available, however).
How Does the Grace Period Impact Interest Accrual?
Both Direct Unsubsidized and Subsidized Loans have a six-month grace period after the borrower graduates. On subsidized loans, the borrower is not responsible for paying interest during the grace period. On an unsubsidized loan, interest continues to accrue during the six-month grace period.
Direct PLUS Loans do not have a grace period. Graduate students do receive an automatic deferment after graduation and interest does accrue during this time period.
How Does Capitalized Interest Work?
While payments are not required on most federal student loans while the student is enrolled in school, students with Direct Unsubsidized or PLUS Loans have the option of making interest-only payments. This can be helpful because, as mentioned previously, after the grace period and at the end of periods of deferment or forbearance, the accrued interest is capitalized on the loan.
Capitalized interest on student loans occurs when the accrued interest is added to the principal balance of the loan (the amount that was originally borrowed). This becomes the new balance of the loan, and interest will continue to accrue based on that new balance.
Think of all that accumulating interest like a snowball rolling down a mountain. You might be able to stay ahead of it for a while, but it also might catch up with you.
Interest Accrual During Deferment and Forbearance
During student loan deferment, interest accrual depends on the type of student loan you hold. Federal Direct Subsidized Loans typically do not accrue interest during approved deferment periods, as the government covers these costs. However, unsubsidized loans, PLUS Loans, and most private loans continue accruing interest even while payments are paused. If this unpaid interest is not addressed, it may capitalize once deferment ends, increasing your overall loan balance and the amount you’ll pay over time.
Forbearance, on the other hand, almost always results in interest accruing regardless of loan type. Whether you have subsidized, unsubsidized, or private loans, interest continues to build during a forbearance period. Interest typically does not capitalize at the end of a forbearance, though.

Understanding How Private Student Loan Interest Works
When thinking about private vs. federal student loans, know that private loans are not subject to the same rules as federal student loans. They’re offered by private companies, and each lender will likely have its own terms and conditions.
The majority of private student loans will start to accrue interest while the student is enrolled in school. Some lenders may allow borrowers to defer payments until after they graduate. In this case, the accrued interest from when the borrower was in school will likely be capitalized on the loan. To be sure of the terms on your loan, review the loan agreement or check in with the lender directly.
Keep in mind that, as mentioned, private student loans don’t always offer the same benefits or borrower protections (things like income-driven repayment options) that federal loans do. Because of this, they are generally considered after all other sources of financing, including federal student loans, have been exhausted.
This table provides an overview of how interest accrues on the various types of loans discussed in this article.
| Type of Loan | Does Interest Accrue While In School? | Grace Period and Interest |
|---|---|---|
| Federal Direct Subsidized Loans | Interest does not accrue while the borrower is enrolled in school at least half-time | Interest does not accrue during the six month grace period |
| Federal Direct Unsubsidized Loans | Interest accrues while the borrower is in school | Interest does accrue during the six month grace period |
| Federal Direct PLUS Loans | Interest accrues while the borrower is in school | Do not have a grace period |
| Private Student Loans | Varies by lender; it is likely that interest will accrue | Varies by lender; some lenders may offer a grace period and interest may accrue |

Can You Minimize Student Loan Interest Accrual While in School?
One way to limit accrued interest is to limit what you borrow in the first place. When it comes to student loans, aim to borrow only what you really need. Perhaps get a part-time job to help cover some of your expenses, make interest-only payments on your loans, and/or consider refinancing your loans after you graduate.
Work-Study or a Part-Time Job
Work-study, for those eligible, or a part-time job can help you take out less in student loans. You can use the money earned to help pay for tuition, books, and living expenses. Minimizing your total student loan amount is one of the best ways to minimize student loan interest accrual. The less you owe in loans, the less you’ll pay in interest.
Make Interest Only Payments
Making student loan payments while in school isn’t likely to be a requirement, but as mentioned earlier, many loans allow borrowers to make interest-only payments while they’re in school. While this won’t eliminate accrued interest, it can reduce the total amount you pay over the life of the loan because the interest won’t capitalize if you’re paying it as it accrues.
Compare and Refinance Loans with Better Terms
Once you begin repaying your student loans, refinancing your student loans can be an effective way to manage interest accrual and reduce overall costs. By comparing lenders and securing a lower interest rate, you may be able to decrease both your monthly payments and the total amount of interest you’ll pay over the life of the loan.
You may also choose to extend the term of your loan, which can decrease your monthly payment. Keep in mind, though, that extending the term will most likely mean you’ll pay more in interest over the life of the loan.
And remember that refinancing federal loans means giving up federal protections and benefits, such as income-driven repayment plans and student loan forgiveness. It can still be a valuable strategy, though, for lowering long-term expenses if the new terms align with your financial goals.

The Takeaway
Interest on many types of student loans accrues while the student is in school. Federal Direct Subsidized Loans are an exception, as the accrued interest is paid for by the government while the student is enrolled in school and during the grace period.
Generally speaking, interest on other types of student loans, including Direct Unsubsidized and PLUS Loans, begins accruing interest when they are disbursed, and continue accruing interest while the student is enrolled. For private student loans, each lender will likely have its own terms and conditions.
Looking to lower your monthly student loan payment? Refinancing may be one way to do it — by extending your loan term, getting a lower interest rate than what you currently have, or both. (Please note that refinancing federal loans makes them ineligible for federal forgiveness and protections. Also, lengthening your loan term may mean paying more in interest over the life of the loan.) SoFi student loan refinancing offers flexible terms that fit your budget.
FAQ
When does student loan interest start accruing?
Student loan interest typically begins accruing as soon as the loan is disbursed. For federal subsidized loans, the government covers the interest while you’re in school and during certain periods. For unsubsidized federal and most private loans, interest starts accruing immediately, even while you’re still enrolled.
Is it better to pay interest while still in school?
Yes, it’s better to pay interest while still in school because it can save you money in the long run. Paying interest while still in school prevents that interest from capitalizing and adding to your loan balance. Even small payments can reduce overall costs.
How is capitalized interest different from regular interest?
Regular interest accrues on your current loan balance, increasing what you owe over time. Capitalized interest, however, is unpaid interest that gets added to your principal balance. Once it capitalizes, future interest is charged on this higher principal, making your total loan cost grow more quickly.
Do private student loans always accrue interest while in school?
Yes, private student loans almost always accrue interest while you’re in school, regardless of your enrollment status. Unlike some federal loans, private lenders rarely offer subsidized options. Interest typically starts accruing at disbursement, and if you don’t make in-school payments, it will continue to grow and may capitalize later.
What’s the difference between subsidized and unsubsidized interest?
Subsidized loans don’t accrue interest while you’re in school or during deferment — the government pays it for you. Unsubsidized loans accrue interest from the moment they’re disbursed, and you’re responsible for all of it. If unpaid, that interest may capitalize, increasing your total loan balance and long-term cost.
