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( 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.

Prn( computes the sum of the principal during a specified period for an amortization
schedule using stored values for ¾æ,
PV, and PMT. pmt1 is the starting payment. pmt2 is the
ending payment in the range.
pmt1 and pmt2 must be positive integers < 10,000. roundvalue
specifies the internal precision the calculator uses to calculate the principal; if you do not
specify
roundvalue, the TI-84 Plus uses the current Float/Fix decimal-mode setting.
