How the Biweekly Payment Calculator Works

It shows how paying half your mortgage every two weeks — which adds up to one extra full payment a year — shortens your term and cuts total interest.

How It Works, Step by Step

The calculator splits your monthly payment in half and applies it every two weeks. Because there are 26 biweekly periods in a year, you make the equivalent of 13 monthly payments instead of 12, and the extra payment goes to principal.

A biweekly schedule reduces only principal and interest, so the benefit is identical in Florida as elsewhere. Just confirm your servicer applies the extra payment to principal rather than holding it, and that no fee is charged to set up biweekly payments — some third-party services charge for what you can do yourself.
