HP 12c Platinum Owner's Handbook

Section 12: Real Estate and Lending 123
Example 1: A borrower is charged 2 points for the issuance of his mortgage. If
the mortgage amount is $60,000 for 30 years and the interest rate is 11½% per
year, with monthly payments, what true annual percentage rate is the borrower
paying? (One point is equal to 1% of the mortgage amount.)
Example 2: Using the same information as given in example 1, calculate the
APR if the mortgage fee is $150 instead of a percentage.
