How it works
A biweekly schedule means you pay half of your monthly mortgage payment every two weeks. Because there are 52 weeks in a year, that adds up to 26 half-payments — the equivalent of 13 monthly payments instead of 12. That one extra payment each year goes entirely to principal.
Over a 30-year mortgage, that single extra annual payment can pay the loan off roughly four to six years early and save tens of thousands of dollars in interest, with no change to your standard of living beyond the budgeting.
You do not necessarily need your lender's official biweekly program — many charge setup fees. You can achieve the same result by adding one-twelfth of your monthly payment to each monthly payment yourself, applied to principal.
