Annual Percentage Rate for a Loan with Fees 
See appendix F for RPN keystrokes for the next two examples. 
The 
annual percentage rate, APR, incorporates fees usually charged 
when a mortgage is issued, which effectively raises the interest rate. The 
actual amount received (the 
PV) by the borrower is reduced, while the 
periodic payments remain the same. The APR can be calculated given 
the term of the mortgage (
N periods), the annual interest rate (I%YR), the 
mortgage amount (new 
PV), and the basis of the fee charged (how the 
fee is calculated). 
Remember the cash-flow sign convention: money paid out is negative, 
money received is positive. 
Example: APR for a Loan with Fees. A borrower is charged two points 
for the issuance of a mortgage. (One point is equal to 1% of the 
mortgage amount.) If the mortgage amount is $60,000 for 30 years 
and the interest rate is 11½% annually with monthly payments, what 
APR is the borrower paying?
