After calculating a payment using Time Value of Money (TVM), enter the periods to amortize and press H!. Then press =to continually cycle through the interest, principal, and balance values (indicated by the 35,1,￿,17, and %$/ annunciators respectively).

Using the TVM example from the previous page, amortize a single payment and then a range of payments.

Amortize the 20th payment of the loan.
