Calculating an Amortization Schedule
Use the amortization functions (menu items
9
,
0
, and
A
) to calculate
balance, sum of principal, and sum of interest for an amortization
schedule.
bal(
bal(
computes the balance for an amortization schedule using stored
values for
æ
,
PV
, and
PMT
.
npmt
is the number of the payment at which
you want to calculate a balance. It must be a positive integer < 10,000.
roundvalue
specifies the internal precision the calculator uses to calculate
the balance; if you do not specify
roundvalue
, then the TI-83 Plus uses the
