Graduated Payment Mortgages
The Graduated Payment Mortgage is designed to meet the needs of young home
buyers who currently cannot afford high mortgage payments, but who have the
potential of increasing earning in the years on come.
Under the Graduated Payment Mortgage plan, the payments increase by a fixed
percentage at the end of each year for a specified number of years. Thereafter,
the payment amount remains constant for remaining life of the mortgage.
The result is that the borrower pays a reduced payment (a payment which is less
than a traditional mortgage payment) in the early years, and in the later years
makes larger payments than he would with a traditional loan. Over the entire
term of the mortgage, the borrower would pay more than he would with
conventional financing.
Given the term of the mortgage (in years), the annual percentage rate, the loan
amount, the percentage that the payments increase, and the number of years
that the payments increase, the following HP-12C program determines the
monthly payments and remaining balance for each year until the level payment is
reached.
