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):

Portion of second year’s payments applied to interest.

Portion of second year’s payments applied to principal.

Number of payments just amortized. Balance remaining after 2 years.

Total number of payments amortized.

Pressing :$or :ndisplays 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:
