Understanding Single Monthly Mortality Rate (SMM) in Mortgage Loans
Definition & meaning
The Single Monthly Mortality Rate (SMM) is a metric used in the mortgage industry to measure the percentage of principal paid off in a mortgage loan within a single month. It reflects the extra principal reduction beyond the scheduled monthly payment. The SMM is calculated as a percentage of the principal balance at the start of the month, specifically by dividing the unscheduled prepayments made during the month by the scheduled balance at the end of that month.
