The rate spread calculator generates the spread between the Annual Percentage Rate (APR) and a survey-based estimate of APRs currently offered on prime mortgage loans of a comparable type utilizing the “Average Prime Offer Rates” fixed or adjustable table, action taken, amortization type, lock-in date, APR, fixed term (loan maturity) or variable term (initial fixed-rate period), and lien status. Rate spread is a calculated field and is NOT simply the APR on the loan application.
A batch rate spread calculator is also available to allow institutions to calculate the rate spread on multiple Loan Application Registers (LARs).
NOTES:
[1] Do not use the rate spread calculator to calculate the HOEPA status; they are two different fields which require two different calculations. See Help for more details.
[2] If the loan application date is before October 1, 2009 and the action taken date is before January 1, 2010, use the old calculator.
[3] APORs are calculated using data from a combination of Freddie Mac's Primary Mortgage Market Survey® and other data. As of January 1, 2016, Freddie Mac no longer publishes (PMMS) results for the 1 - year ARM product. For details about the sources used since then, see the table of mortgage rate survery data.
