Calculating Amortization
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
current Float/Fix decimal-mode setting.
