2. PRESENT VALUE CONCEPTS Appendix B

3. PRESENT VALUE CALCULATIONS The time value of money – $1.00 in your pocket today is worth more than $1.00 in your pocket tomorrow Example: $1000 invested today at 5% interest will be worth $1050 one year from now.

4. NATURE OF INTEREST Interest is payment for the use of money Principal (p) is the original amount of the investment Interest Rate (i) is the annual percentage of the principal Number of periods (n) is the time period that the principal is borrowed or invested

5. SIMPLE INTEREST Simple interest is calculated on the principal amount only = X X Example: If you borrowed $1000 for 3 years at a simple interest rate of 9% annually, you would pay $270 in interest Interest = p x i x n =$1000 x.09 x 3 =$270 Interest Principal (p) Interest Rate (i) Number of Periods (n)

6. COMPOUND INTEREST Compound interest is the return on (or growth of) the principal for two or more time periods. It calculates interest on the principal and the interest earned to date (if the interest is left on deposit)

7. COMPOUND INTEREST EXAMPLE First Canadian Bank Compound Interest CalculationCompound Interest Accumulated Year-End Balance Year 1 $1000 x 9%$90.00$1090.00 Year 2 $1090.00 X 9%$98.10$1188.10 Year 3 $1188.10 X 9%106.93$1295.03 $295.03 You would make approx. $25.03 more with compound interest than simple interest in this example.

8. PRESENT VALUE VARIABLES The process of determining the present value of a number is called discounting the future amount The 3 variables are: –The dollar amount to be received (the future amount) –The length of time until the amount is received (number of periods) –The interest rate (discount rate)

9. PRESENT VALUE OF A SINGLE FUTURE AMOUNT If you would like to have $1000 at the end of a year, how much do you need to invest today? (Assume a 5% interest rate) Present Value (PV)=Future Value (FV) (1 + i) n =1000 ÷(1 + 5%) 1 =1000 ÷ 1.05 =$952.38

10. PRESENT VALUE OF A SINGLE FUTURE AMOUNT (con’t) Using the same example, how much would you need to save if you have 2 years to save instead of 1? Present Value (PV)=Future Value (FV) (1 + i) n =1000 ÷(1 + 5%) 2 =1000 ÷ 1.05 ÷ 1.05* =$907.03 *Or =1000 ÷ (1.05 x 1.05)

11. PRESENT VALUE TABLES Tables may also be used to show the present value of $1.00 for n periods at various interest rates (i) See the table provided or pg. B4 in your textbook PV = FV x PV factor FV = PV ÷ PV factor

12. EXAMPLES USING THE PRESENT VALUE TABLE 1.You would like to invest some money today at 8% interest. You want to have $20,000 saved in 5 years for your first car. How much should you invest today? PV = FV X PV factor = $20,000 X.68058 = $13,612

13. EXAMPLES USING THE PRESENT VALUE TABLE 2.You have $16,000 saved and would like to invest some money today at 5% interest. How much will you have within 4 years? FV = PV ÷ PV factor = $16,000 ÷.82270 = $19,448

14. EXAMPLES USING THE PRESENT VALUE TABLE 3.You have $10,000 to invest today and would like to double your money in 7 years. Approximately what interest rate would you need to have. PV = FV X PV factor $10,000 = $20,000 X x $10,000 ÷ $20,000 =.5 Using the table when n=7,.5 occurs between 10% and 11%, so approx. 10.5% interest rate will be needed to double your money.

15. PRESENT VALUE OF A SERIES OF FUTURE AMOUNTS (ANNUITIES) Annuities are a series of periodic receipts or payments They are often used for loan agreements, mortgage notes, lease contracts and pension obligations The variables needed are: –The discount rate (i) –The number of periods (n) –The amount of the periodic receipts or payments (FV)

16. PRESENT VALUE OF AN ANNUITY For example if you will receive $1,000 cash annually for 3 years at the discount rate of 4%, what is the present value? PV= (?)100010001000 Now 1 23 years The easiest way to calculate this is to use an annuity table. See the table provided or page B7 in your textbook.

17. PRESENT VALUE OF AN ANNUITY Using the example on the previous slide, the solution would be: PV= FV(each payment) x PV annuity factor =$1,000 X 2.77509 =$2,775.09

18. INTEREST RATES AND TIME PERIODS When using the tables, there are situations when the interest rate and/or time period must be adjusted –If interest rates are not included in the table you must interpolate the values (eg. 3 ½%) –If payments are monthly, quarterly or semi- annually then the interest rate must be converted. (eg. semi-annual payments at 4% annual interest rate; 2 periods at 2% would be used in the table)

19. PRESENT VALUE OF AN ANNUITY EXAMPLE I am thinking of retiring when I am 60 years old and I am trying to figure out how much I would need to have saved up. I would need approx. $75,000 a year to live on for the next 20 years and I am hoping that to get at least a 4% interest rate. How much would I need to have in my retirement fund when I am 60? PV = $75,000 X 13.59033 = $1,019,274.75

20. PRESENT VALUE OF A BOND To calculate the present value of a bond, both the principal and the interest payments must be discounted. Two calculations are requried. The annuity table would be used for the interest payments. The principal amount would use the table for a single amount.

21. PRESENT VALUE OF A BOND EXAMPLE A four year 6% bond with a face value of $100,000 is issued. Interest will be paid semi-annually. Present Valuei=3%Principal Amount (?) $100,000 Now12345678 n=8 Present Valuei=3%Interest Payments (? 3000 3000 3000 3000 3000 3000 3000 3000 Now12345678 n=8

22. PRESENT VALUE OF A BOND EXAMPLE (con’t) Using the tables: Principal Amount PV = 100,000 x.78941 =$78,941.00 Interest Payments PV = 3000 x 7.01969 =$21,059.07 Total =$78,941 + $21,059 =$100,000
