A
mortgage on which payments are made every two weeks. Mortgages are typically
paid monthly. The bi-weekly payment amount is calculated by dividing a monthly
amount in two. However, 26 payments are made over the course of a year, because
some months are longer than just the two bi-weekly payment periods. The effect
is an accelerated payment schedule, in which principal is paid down faster and
the amount of interest paid over the life of the mortgage is decreased.
