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( 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-84
Plus uses the current Float/Fix decimal-mode setting.
