Frequently Asked Questions
A biweekly mortgage payment schedule splits your monthly payment in half and you pay every two weeks. This results in 26 half-payments per year, equivalent to 13 full monthly payments, which helps pay off your mortgage faster.
Standard biweekly uses 26 payments per year (half of monthly). Accelerated biweekly uses 24 payments per year (paying half of monthly every two weeks but only 24 times per year, which is less common). The calculator shows both options.
Savings depend on your loan amount, interest rate, and term. Typically, you can save thousands in interest and shorten your loan term by several years.
