573.35ÞP –573.35 Enters PMT (with minus sign for cash
paid out).
g –573.35 Sets payment mode to End.
12f! –6,608.89 Portion of first year’s payments (12
months) applied to interest.
~ –271.31 Portion of first year’s payments
applied to principal.
:$ 49,728.69 Balance remaining after 1 year.
:n 12.00 Total number of payments amortized.
The number of payments keyed in just before f! is pressed is taken to be the
payments following any that have already been amortized. Thus, if you now press
12f!, your hp 12c will calculate the amounts applied to interest and to the
principal from the second year’s payments (that is, the second 12 months):

12f! –6,570.72 Portion of second year’s payments
applied to interest.
~ –309.48 Portion of second year’s payments
applied to principal.
dd 12.00 Number of payments just amortized.
:$ 49,419.21 Balance remaining after 2 years.
:n 24.00 Total number of payments amortized.
Pressing :$ or :n displays the number in the PV or n register. When you
did so after each of the last two calculations, you may have noticed that PV and n
had been changed from their original values. The calculator does this so that you
can easily check the remaining balance and the total number of payments
amortized. But because of this, if you want to generate a new amortization
schedule from the beginning, you must reset PV to its original value and reset n to
0.
For example, suppose you now wanted to generate an amortization schedule for
each of the first two months:
