How it works

Instead of one monthly payment, you pay half the monthly amount every two weeks. That adds up to 26 half-payments per year — the equivalent of 13 full monthly payments instead of 12. The extra payment goes straight to principal.

Assumptions

26 half-payments per year, periodic rate = annual rate / 26, adjusted final payment. Illustration assumes each half-payment is credited when made; actual lender crediting practices vary — some servicers hold partial payments until a full payment accumulates, and some charge enrollment fees.
