Prepayment rate formula
Conditional Prepayment Rate (CPR) Formula The formula for calculating CPR is based on another prepayment metric called Single Monthly Mortality (SMM). It represents the fraction of mortgage loans principal that has prepaid during the month on top of the regular principal payment. rate of 6.0% CPR.To calculate the prepayment rate for any specific multiple of PSA, adjust the annual prepayment rate at 100% PSA by that multiple.(For example,200% PSA assumes prepayment rates equal to twice the CPRs from the 100% PSA model,on a 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. Manufactured-housing prepayment curve ( MHP) is a prepayment schedule that is stepped up in the 1 st 24 months, starting at 3.7%, with 0.01% increments, then leveling off at 6% in the 24 th month. Sometimes an accelerated MHP is used, where 150% or 200% of the percentages are used. The reason the CPR comes out exactly 5.000%, is that I have entered a default CPR prepayment cash flow that is equal to 5.00% for this pool structure example. The yellow cells for prepayments can be changed. If you needed a CPR for a period, for example, the 13th to the 24th,
The PSA Prepayment Model is a prepayment scale developed by the Public Securities Association in 1985 for analyzing American mortgage-backed securities. The PSA model assumes increasing prepayment rates for the first 30 months "Calculation Standard Set on C.M.O. Yields". The New York Times. June 14, 1985.

The CPR is an annual prepayment rate. For example, if the CPR is 8%, we would expect that 8% of the remaining principal will be prepaid each year. The single-monthly mortality rate (SMM) is the percentage of a pool's remaining principal that is expected to be prepaid each month. SMM is the CPR converted from an annual term to a monthly rate.
