Student Loan Interest Capitalization: What It Is and How to Limit It
Short answer: Capitalization is when unpaid interest is added to your loan balance, so future interest is charged on a larger amount. Federal loans accrue simple interest daily, and capitalization happens only at certain events, which are fewer than before. Private loans may capitalize more often. Paying interest as it builds is the most reliable way to keep your balance from growing.
Accrued interest vs capitalized interest
Accrued interest is interest that builds up over time on your balance. On federal loans it is calculated daily on the principal alone. Capitalized interest is accrued interest that has been added to your principal. From then on, interest is charged on the new, larger principal. That extra step is what makes a balance grow even when you have been making payments.
Hypothetical example: A loan with $20,000 principal collects $1,000 in unpaid interest. If that interest is capitalized, the principal becomes $21,000 and new interest is calculated on $21,000.
When capitalization can happen
The Department of Education removed several capitalization events from federal Direct Loans in 2023, such as certain exits from forbearance and some income-driven plan changes. Sources disagree about which events remain, and rules can differ for older loans such as FFEL loans held by commercial lenders. Events often named include consolidating your federal loans, and unpaid interest on some loans when certain periods end. Check your own situation on StudentAid.gov or ask your servicer which events apply to each loan.
Private lenders set their own rules, and many capitalize interest at the end of a grace period, after a forbearance, or even monthly. Your loan agreement controls.
How to limit capitalization
- Pay the interest as it builds, even when you cannot pay the full amount. Partial payments reduce what could be added later, and interest you pay may count toward the student loan interest deduction.
- Use the grace period to pay accruing interest on unsubsidized loans.
- Be careful with pauses. Interest usually keeps building during forbearance. See deferment vs forbearance.
- Think before consolidating. Read consolidation pros and cons.
- Choose a plan that covers interest. Some income-driven plans reduce unpaid interest. See how to apply for RAP.
How to see what is happening on your loans
- Log in at StudentAid.gov and open each loan’s details.
- Look at the principal, the accrued interest and the interest rate.
- Compare the principal now with a few months ago. A jump means capitalization may have happened.
- Ask your servicer for a written explanation if you see an increase you do not understand.
If you cannot tell which servicer to call, see how to find your servicer and loans.
Common misconceptions
- “Federal student loans compound daily.” Federal loans accrue simple daily interest, which only grows on a bigger base after capitalization.
- “A lower payment always saves money.” If the payment is below the monthly interest, the balance can grow. Compare options in how to lower student loan payments.
- “All old articles are current.” Rules changed, so verify with an official source.
