Biweekly Payment Calculator FAQ

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.

The Complete Guide

Biweekly payments are a painless way to pay your mortgage off early. By aligning payments with biweekly paychecks, many borrowers barely notice the difference, yet they make one extra full payment every year without budgeting for it.

The mechanism is simple arithmetic: 26 half-payments equal 13 monthly payments, and that 13th payment goes straight to principal. The result is a shorter term and less total interest, with no change to your required payment amount.

Before enrolling in a paid biweekly program, know that you can replicate the benefit for free by adding one-twelfth to each monthly payment. The calculator shows the savings either way so you can decide how to capture them.

How the Calculator Works

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.
