Example 1: Compound Interest
If you purchase an item for $20,000 with a loan that has an annual
interest rate of 5.5%, compounded monthly, how many payments of
$500 per month would it take to pay off the loan?
Set: Payment = End (end of period)
I%
Interest rate (Annual) 5.5%
PV
Purchase amount (Present Value) $20,000
PMT
Payment amount −$500
FV
Final amount (Future Value) $0
P/Y
Number of payments per year 12
C/Y
Number of times per year interest is compounded 12
