Interest accrues on federal loans the moment they are disbursed, but you may not owe it yet

Federal student loans begin accruing interest as soon as the money hits your school's account, not when you graduate or leave school. However, whether you actually have to pay that interest depends on the loan type. On subsidized loans, the federal government covers the interest while you are in school at least half-time, during your grace period, and during deferment. On unsubsidized loans, interest accrues from day one and you are responsible for it — though you can choose to pay it as it builds up or let it capitalize (get added to your principal) later.

The distinction matters because unpaid interest on unsubsidized loans grows into a larger balance you will owe. If you borrow $10,000 in unsubsidized loans and do not pay the accrued interest before repayment begins, that interest gets capitalized and you end up paying interest on interest for the rest of the loan term.

Key Takeaways

  • Subsidized loans stop accruing interest while you are enrolled at least half-time, but unsubsidized loans accrue interest continuously regardless of enrollment status.
  • Interest on unsubsidized loans accrues from the disbursement date, and unpaid interest capitalizes (gets added to your loan balance) when you enter repayment.
  • You can see how much interest has accrued on your loans by logging into your Federal Student Aid account or contacting your loan servicer.
  • Paying accrued interest before repayment begins prevents capitalization and saves you money over the life of the loan.

How accrual works for subsidized versus unsubsidized loans

Subsidized loans (Direct Subsidized Loans and older Stafford Loans) do not accrue interest while you are enrolled at least half-time, during your six-month grace period after you leave school, or during certain deferment periods. The government pays the interest on your behalf during these times. Once you enter repayment, interest begins accruing and you owe it.

Unsubsidized loans (Direct Unsubsidized Loans, PLUS loans, and older Stafford Loans) accrue interest from the moment they are disbursed. You are responsible for this interest at all times — while in school, during grace, during deferment, and during repayment. The interest does not stop accumulating just because you are still a student.

Parent PLUS loans and Grad PLUS loans are always unsubsidized, so interest accrues immediately. If you take out a PLUS loan to cover tuition in September, interest is building from September onward, even if you do not make a payment until after graduation.

When interest capitalizes and increases your loan balance

Capitalization is when unpaid interest gets added to your principal balance. Once capitalized, you pay interest on that interest for the remainder of the loan term. For unsubsidized loans, capitalization typically happens when you enter repayment — your servicer adds all the accrued interest to your balance, and your first payment is calculated on this larger amount.

Capitalization can also occur if you enter forbearance or certain income-driven repayment plans. Some plans capitalize interest monthly if your payment does not cover the full amount accruing. This is why paying down accrued interest before repayment begins is one of the most direct ways to reduce what you ultimately owe.

If you have multiple unsubsidized loans, interest capitalizes on each one separately. A $5,000 unsubsidized loan borrowed as a freshman will have more accrued interest by graduation than a $5,000 unsubsidized loan borrowed as a senior, because it has had more time to accrue.

How to find out how much interest has accrued on your loans

Log into your account at studentaid.gov using your FSA ID. Under "My Aid" you will see a list of all your federal loans. Click on each loan to view its current balance, interest rate, and accrued interest. The accrued interest is listed separately from the principal you borrowed.

You can also contact your loan servicer directly — the servicer's name and phone number appear on your loan details page at studentaid.gov. Servicers can tell you the exact amount of accrued interest, when it will capitalize, and what your balance will be once it does.

If you are still in school, your school's financial aid office can also provide this information. Some schools include accrued interest on your loan disbursement statements or financial aid award letters.

Paying interest before repayment to avoid capitalization

You can pay accrued interest on unsubsidized loans at any time, even while you are still in school. Paying it before you enter repayment prevents capitalization and keeps your principal balance lower. If you have $15,000 in unsubsidized loans and $1,200 in accrued interest, paying that $1,200 before repayment means you owe interest only on $15,000, not on $16,200.

To pay accrued interest, contact your loan servicer and ask how to make a payment toward interest only. Some servicers allow you to pay online; others require a check or bank transfer. Make sure the payment is credited to interest and not applied to principal — you want to reduce the accrued interest balance specifically.

If you cannot pay all the accrued interest at once, paying some of it is still worthwhile. Even a partial payment reduces the amount that will capitalize and compound over time.

Interest accrual during school breaks and leaves of absence

Interest continues to accrue on unsubsidized loans during winter break, summer break, and any other time you are not enrolled, as long as you are not enrolled at least half-time. If you drop to part-time status, unsubsidized interest keeps accruing. Subsidized loans stop accruing only when you are enrolled at least half-time.

If you take a leave of absence or withdraw from school, your grace period does not begin until you are no longer enrolled at least half-time. During the leave, unsubsidized interest continues to build. Subsidized loans stop accruing interest once you fall below half-time enrollment.

What happens to accrued interest if you consolidate your loans

If you consolidate your federal loans into a Direct Consolidation Loan, any accrued interest on your existing loans is capitalized into the new loan balance. You cannot avoid this capitalization through consolidation. However, consolidation can lower your monthly payment by extending the repayment term, which may be worth the cost of capitalization depending on your situation.

Before consolidating, calculate how much accrued interest you have and what your new balance will be after capitalization. Your loan servicer can provide this estimate. If you have time before consolidation, paying down accrued interest first will reduce the amount that gets capitalized into the new loan.

Frequently Asked Questions

Does interest accrue on subsidized loans while I am in school?

No. The federal government pays the interest on subsidized loans while you are enrolled at least half-time. Interest begins accruing once you leave school or drop below half-time enrollment and your grace period ends. Unsubsidized loans accrue interest from day one, regardless of enrollment status.

What is the difference between accrued interest and capitalized interest?

Accrued interest is interest that has built up but has not yet been added to your loan balance. Capitalized interest is accrued interest that has been added to your principal. Once capitalized, you pay interest on that interest for the rest of the loan term. Capitalization typically happens when you enter repayment on unsubsidized loans.

Can I pay interest while I am still in school?

Yes. You can pay accrued interest on unsubsidized loans at any time, even while enrolled. Paying it before repayment begins prevents capitalization and reduces the total amount you will owe. Contact your loan servicer to arrange a payment toward interest only.

What happens to accrued interest during my grace period?

On subsidized loans, the government continues to pay interest during your six-month grace period, so no interest accrues. On unsubsidized loans, interest continues to accrue during grace. When you enter repayment, any unpaid accrued interest on unsubsidized loans is capitalized into your balance.

Does accrued interest affect my credit score?

Accrued interest itself does not appear on your credit report. However, if you do not pay your loan when repayment begins, missed payments will be reported and will damage your credit. Paying accrued interest before repayment is one way to reduce your first payment and make it easier to stay current.
