If you want to generate an amortization schedule but do not already know the
monthly payment:
1. Calculate PMT as described on page 46.
2. Press 0n to reset n to zero.
3. Proceed with the amortization procedure listed on page 54 beginning with
step 6.
Example: Suppose you obtained a 30-year mortgage instead of a 25-year
mortgage for the same principal ($50,000) and at the same interest rate (13
1 /
4
%)
as in the preceding example. Calculate the monthly payment, then calculate the
amounts applied to interest and to the principal from the first month’s payment.
Since the interest rate is not being changed, do not press fCLEARG; to
calculate PMT, just enter the new value for n, reset PV, then press P.
