Accrued Interest Calculator

Even if you are not currently making payments toward your loan, interest continues to accrue (grow).

See how accrued interest could affect your loan balance, and how paying a little more toward your loan can reduce your principal amount.

Note: Calculator assumes the interest rate remains the same and that unpaid interest is not capitalized - added to the principal amount of your loan - at any time.1

Enter your loan balance.
Enter your interest rate.
Enter a number of months.
Enter your payment amount.


Correct the fields highlighted above.


Amounts are estimates.

See how paying more can have a positive impact on your loan balance. If you entered "Never" on the left, try selecting a different frequency and enter a manageable payment amount. Or, if you are are already making payments, try increasing the amount. The new calculation will show you how your loan balance can change.
