Amortization
If computing bal(), pmt2 = npmt
Let bal(0) = RND(PV)
Iterate from
m = 1 to pmt2
then: bal( ) =bal(pmt2)
GPrn( ) =bal(pmt2) N bal(pmt1)
GInt( ) =(pmt2 N pmt1 +1) Q RND(PMT) N GPrn( )
where:
RND =round the display to the number of decimal
places selected
RND12 =round to 12 decimal places
Balance, principal, and interest are dependent on the values of PMT, PV, I/
Y
, and pmt1 and pmt2.
