Simple vs. Compound Interest
$10,000 Savings Account @ 12% a year
Simple $10,000 x .12 -$1200.00 Total at years end: -$11,200
Compounded Monthly 12%/12 = 1% per month $10,000 x .01 -$100.00 $10,100 x .01 -$101.00 $10,201 x .01 -$102.01 $10,303.01 x .01 …etc. Total at year’s end -$11,268.25
Interest for Payment Period
i (in Excel “Rate”)
APR/number of payments per year
e. g., 12% APR; monthly payments
- =12%/12
- —i = 1%
Present Value of Money (Pv)
What a future amount of money is worth now…
- No time interval
- No lost opportunity
- No risk
- No inflation
Future Value of Money
The value of money at some point in the future based upon periodic, constant payments and a constant interest rate

Fv Example
Savings Account
- $100 Initial Deposit (Pv)
- $100 Credit Per month (Payment)
- —Beginning of period
- 3% APR
- 30 years
Fv=$58,665.06
Payments over Time (Annuity)
Payment
- Principal reduction
- Interest
Value of Payment Depends upon: -Term of annuity -Percent of interest -Frequency of compounding -Timing of payment
Term of Annuity
Usually expressed in years
- Number of payments depends upon schedule
- Monthly payments (12 per year)
- Total number of payments = 12 times term in years
- n (In Excel “Nper”)
- Quarterly payments (4 per year)
- n = 4 X term in years
Period of an Annuity
Interval of payments
- Monthly
- Quarterly
- Weekly
- Semi-annually
- Annually
- Bi-annually
- Etc.
Timing of payments
Beginning of period
LOAN:
-Reduces principle before interest for period is computed
SAVINGS:
-Increases principle before interest is computed
End of period
LOAN:
-Computes interest before principle is reduced by payment
SAVINGS:
-Computes interest before increase in principle
Payment Timing:
Beginning vs. End
Loan values
- $30,000
- 5 Year Term
