How Do Biweekly Mortgage Payments Work?

 

In the early years of a longterm loan, most of the payment is applied toward interest. Home buyers can shave years off their loan by paying bi-weekly & making extra payments. Bi-weekly payments help you pay off principal in an accelerated fashion — before interest has a chance to compound on it.

In making biweekly payments, those 26 annual payments effectively create an additional (13th) month of regular payments in each calendar year.
