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
ææ
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-82 STATS uses the current
Float/Fix decimal-mode setting.
bal(npmt[,roundvalue])
GPrn( computes the sum of the principal during a specified period
for an amortization schedule using stored values for
æ
ææ
æ, 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-82 STATS uses the current
Float/Fix decimal-mode setting.
Note: You must enter values for æ
ææ
æ, PV, PMT, and before computing
the principal.
GPrn(pmt1,pmt2[,roundvalue])
GInt(
computes the sum of the interest during a specified period
for an amortization schedule using stored values for
æ
ææ
æ, 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 interest; if you do not specify roundvalue, the
TI-82 STATS uses the current
Float/Fix decimal-mode setting.
