Annual Percentage Rate Calculations With Fees
Borrowers are usually charged fees in connection with the issuance of a mortgage,
which effectively raises the interest rate. The actual amount received by the
borrower (PV) is reduced, while the periodic payments remain the same. Given the

of the fee charge (how the fee is calculated), the true Annual Percentage Rate (APR)
may be calculated. Information is entered as follows:
