Understanding the 30/360 Day Count Convention in Finance
The 30/360 day count convention is a method used in financial calculations, particularly for fixed-income securities like bonds and mortgages, to determine the number of days between two dates. It assumes that every month has 30 days and every year has 360 days. Although it doesn’t reflect actual calendar days, it simplifies interest calculations and provides a consistent basis for standardization.
