1. Translating Today’s Benefits to the Future
Suppose you want to know how much money you would have in 5 years if you placed $5,000 in the bank today at an interest rate of 6% compounded annually.
future value of a one-time investment.
The future value is the accumulated amount of your investment fund at the end of a specified period.

2. This is an exercise that involves the use of compound interest.
Compound interest - Situation where you earn interest on the original investment and any interest that has been generated by that investment previously.
Earn interest on your interest
First year: $5,000(1+.06) = $5,300
Second year: $5,300(1+.06) = $5,618
Third year: $5,618(1+.06) = $5,955.08
Fourth year: $5,955.08(1+.06) = $6,312.38
Fifth year: $6,312.38(1+.06) = $6,691.13

3. Effect of Compound Interest

4. Formula: FV = PV(1 + r)n Compounding Factors:
r = interest rate divided by the compounding factor
(yearly r / compounding factor)
n = number of compounding periods
(yearly n * compounding factor)
PV = Present Value of your investment
Compounding Factors:
Yearly = 1
Quarterly = 4
Monthly = 12
Daily = 365

5. Please note that I will always report r’s and n’s as yearly numbers
You will need to determine the compounding factor
All of your terms must agree as to time.
If you are taking an action monthly (like investing every month), then r and n must automatically be converted to monthly compounding.
If you are rounding in time value of money formulas, you need AT LEAST four (4) numbers after the zeros (0)
r = .08/12
r= (not or or etc.)

6. Yearly compounding
PV = 5000
r = .06
n = 5
FV = $5,000(1.06)5
= $6,691.13
Monthly compounding
r = (.06/12) = .005
n = 5(12) = 60
FV = $5,000(1+.005)60
= $6,744.25

7. Implications… _____ frequency of compounding = ___ FV
_____ length of investment = ____ FV
_____ interest rate = _____ FV

8. How do the calculations change if the investment is repeated periodically?
Suppose you want to know how much money you would have in 24 years if you placed $500 in the bank each year for twenty-four years at an annual interest rate of 8%.
future value of a periodic investment or future value of an annuity (stream of payments over time) = FVA

9. The formula is...
where PV = the Present Value of the payment in each period
r = interest rate divided by the compounding factor
n = number of compounding periods

10. Let’s try it… $500/year, 8% interest, 24 years, yearly compounding
PV = 500
r = .08
n = 24
= 500 ( )
= $33,382.38

11. Let’s try it again…
$50/month, 8% interest, 5 years, monthly compounding
PV = 50
r = (.08/12) =
n = 5(12) = 60

12. = 50 ( )
= $
Try again with n=120
FVA=$

13. More Practice
You have a really cool grandma who gave you $1,000 for your high school graduation. You invested it in a 5-year CD, earning 5% interest. How much will you have when you cash it out if it is compounded yearly?
How much will you have if it is compounded monthly?
How much will you have if it is compounded daily?

14. Yearly Compounding
1000(1+.05)5 =$
Monthly Compounding
r = (.05/12) =
n = 5(12) = 60
1000( )60 =$
Daily Compounding
r = (.05/365) =
n = 5(365) = 1825
1000( )1825 =$

15. Some more practice...
You have decided to be proactive for the future, and will save $25 a month. At the end of 10 years, how much will you have saved, if you earn 8% interest annually?
Monthly Compounding
FVA =
PV = $25 a month
r = (.08/12) =
n = (10)(12) = 120
FVA = $

16. The Time Value of Money in Decision Making
Assume you have the option of two different investment options. First, a friend wanted to borrow $5,000 for three years and pay you back $6,000 in a lump sum. Second, you could invest the same $5,000 for three years in a government bond paying 7 percent annual interest. Which investment would be the best financial decision?
FV = (PV)(1 + r) n
= (5,000)(1+.07)3
= 5,000 x
= $6,125.22
You would earn $ more by investing in the government bonds.
