Bi-Weekly Mortgages
Your calculator includes a built-in Bi-Weekly mortgage function (
s
T
), which allows you to convert established, fully amortized
monthly mortgages into Bi-Weeklies (in which one-half the monthly
payment is made every two weeks). Because you make two extra
half-payments per year (e.g., 26 Bi-Weekly payments is like making
13 payments/year), these kinds of mortgages can amount to large
interest savings and a substantial reduction in the time it takes to
pay them off.
You begin solving these problems by setting up the initial monthly
mortgage and then pressing
s T
. The first press of the
T
displays the Bi-Weekly term. The second press of
T
shows the
total interest savings over the entire mortgage, a third press calcu-
lates the total interest paid, a fourth press shows the total principal
paid, and a fifth press shows the total P&I payments. A press of
p
will calculate the Bi-Weekly payment.

savings, total payments and the Bi-Weekly payment.
