Conditional Prepayment Rate Calculator

Use our free conditional prepayment rate calculator to easily see your payment rate on any outstanding debts. Our CPR calculator uses the following formula:

Annualized Rate of Monthly Prepayments(ARM)/Outstanding Balance(OB)*100=Conditional Prepayment Rate

In an example scenario, we pay $10,000 a year on our outstanding debt of $90,000.

ARM=10000

OB=90000

10000/90000*100=9%

‍

This means that our conditional prepayment rate is 9%. This is a general calculator, so it does not account for fluctuations in your ARM amounts or other outliers. If you have any ideas to improve this calculator, let us know by clicking the icon in the bottom right corner and leaving us a message!
