A biweekly payment plan splits the monthly principal-and-interest amount in half and applies that half every two weeks. Over a year that is 26 half-payments—about one extra full monthly payment.
Core idea
Extra principal and slightly more frequent payments reduce interest under a fixed-rate model. Results depend on rate, balance, and term.
