A conditional prepayment rate (CPR) indicates a loan prepayment rate at which a pool of loans, such as a mortgage backed security's (MBS), outstanding principal is paid off. Another specification that has been used is the constant prepayment rate (CPR), also known as the "conditional prepayment rate." This specification assumes that the percentage of the principal However, since the mortgage payments happen monthly, we need to calculate the monthly prepayment rate. SMM is a measure of the monthly mortgage prepayment rate of the security’s mortgage pool. Let’s take an example to understand how SMM can be calculated. Assume that the outstanding loan is $100,000, Constant prepayment rate (CPR) (aka conditional prepayment rate), is the compounded percentage of the loan pool that is expected to prepay in the coming year. Home-equity loans (HELs) and student loans are based on this model. CPR = Annualized Rate of Monthly Prepayments / Outstanding Balance at Beginning of Period. The prepayment rate of a mortgage pool may be expressed in a number of different ways. These measures are equally valid,although a particular method may be more useful in a given instance. a.

However, if the 9 percent CPR occurs for the 20th month, then the speed would be

Prepayment forces the buyer to reinvest the principal, often at a lower rate of return. Changes in interest rates certainly account for most prepayment risk, as anyone who has ever refinanced into a lower-rate mortgage can understand. But interest rate changes alone can't fully predict prepayment activity. Chart 1 also illustrates how prepayment rates (left axis) generally move in the opposite direction of the 30-year mortgage rate (right axis), illustrating how declines in mortgage rates generally lead to faster prepayment rates and vice versa. Chart 2 illustrates the comparison of pool loan-origination years for a given TBA-eligible MBS coupon. monthly prepayment and liquidation rates The standard MBS valuation model uses a constant monthly partial prepayment rate, p , and a constant monthly liquidation rate, q , to generate the amortization schedule for a hypothetical mortgage used to represent the underlying mortgage pool.
