Present Value and Future Value Present Value today of a future cash flow. Future Value Amount to which an investment will grow after earning interest 3

Future Values Future Value of $100 = FV 4

Future Values $$$$$$$ Example - FV What is the future value of $100 if interest is compounded annually at a rate of 7% for two years? 5

Future Values with Compounding 1800 1600 FV of $100 1400 1200 0% 5% 10% 15% Interest Rates 1000 800 600 400 200 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Number of Years 6

Present Value Present value = PV 7

Present Value Discount factor = DF = PV of $1 Discount factors can be used to compute the present value of any cash flow 8

Present Value � The PV formula has many applications. Given any variables in the equation, you can solve for the remaining variable. Also, you can reverse the prior example. 9

Present Values with Compounding 120 100 PV of $100 Interest Rates 80 0% 5% 10% 15% 60 40 20 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Number of Years 10

Valuing an Office Building Step 1: Forecast cash flows Cost of building = C 0 = 700, 000 Sale price in Year 1 = C 1 = 800, 000 Step 2: Estimate opportunity cost of capital If equally risky investments in the capital market offer a return of 7%, then Cost of capital = r = 7% 11

Valuing an Office Building Step 3: Discount future cash flows Step 4: Go ahead if PV of payoff exceeds investment 12

Net Present Value 13

Risk and Present Value �Higher risk projects require a higher rate of return �Higher required rates of return cause lower PVs 14

Risk and Present Value 15

Risk and Net Present Value 16

Net Present Value Rule �Accept investments that have positive net present value Example Use the original example. Should we accept the project given a 10% expected return? 17

Rate of Return Rule �Accept investments that offer rates of return in excess of their opportunity cost of capital Example In the project listed below, the foregone investment opportunity is 12%. Should we do the project? 18

Multiple Cash Flows For multiple periods we have the discounted cash flow (DCF) formula 19

Net Present Values $30, 000 $ 870, 000 Present value Year 0 0 1 2 Year -$700, 000 30, 000/1. 12 = $26, 786 870, 000/1. 122 = $693, 559 Total = $20, 344 20

Shortcuts �Sometimes there are shortcuts that make it very easy to calculate the present value of an asset that pays off in different periods. These tools allow us to cut through the calculations quickly. 21

Shortcuts Perpetuity - Financial concept in which a cash flow is theoretically received forever. 22

Shortcuts Perpetuity - Financial concept in which a cash flow is theoretically received forever. 23

Present Values Example What is the present value of $1 billion every year, for all eternity, if you estimate the perpetual discount rate to be 10%? 24

Present Values Example - continued What if the investment does not start making money for 3 years? 25

How to Value Annuities Annuity - An asset that pays a fixed sum each year for a specified number of years 26

Perpetuities & Annuities PV Annuity Factor (PVAF) - The present value of $1 a year for each of t years 27

Short Cuts Annuity - An asset that pays a fixed sum each year for a specified number of years. Asset Year of Payment 1 Perpetuity (first payment in year 1) Perpetuity (first payment in year t + 1) Annuity from year 1 to year t 2…. . t t+1 Present Value

Costing an Installment Plan Example Tiburon Autos offers you "easy payments" of $5, 000 per year, at the end of each year for 5 years. If interest rates are 7%, per year, what is the cost of the car? 5, 000 Present Value at year 0 5, 000 Year 0 1 2 3 4 5 29

Winning Big at the Lottery Example The state lottery advertises a jackpot prize of $590. 5 million, paid in 30 installments over 30 years of $19. 683 million per year, at the end of each year. If interest rates are 3. 6% what is the true value of the lottery prize? 30

Annuity Due Annuity due - Level stream of cash flows starting immediately How does it differ from an ordinary annuity? How does the future value differ from an ordinary annuity? 31

Annuities Due: Example: Suppose you invest $429. 59 annually at the beginning of each year at 10% interest. After 50 years, how much would your investment be worth? 32

Paying Off a Bank Loan Example - Annuity You are purchasing a TV for $1, 000. You are scheduled to make 4 annual installments. Given a rate of interest of 10%, what is the annual payment? 33

FV Annuity Short Cut Future Value of an Annuity – The future value of an asset that pays a fixed sum each year for a specified number of years. 34

FV Annuity Short Cut Example What is the future value of $20, 000 paid at the end of each of the following 5 years, assuming your investment returns 8% per year? 35

Constant Growth Perpetuity g = the annual growth rate of the cash flow 36

Constant Growth Perpetuity NOTE: This formula can be used to value a perpetuity at any point in time. 37

Constant Growth Perpetuity Example What is the present value of $1 billion paid at the end of every year in perpetuity, assuming a rate of return of 10% and a constant growth rate of 4%? 38

Effective Interest Rates Effective Annual Interest Rate –Interest rate that is annualized using compound interest Annual Percentage Rate - Interest rate that is annualized using simple interest 39

EAR & APR Calculations Annual Percentage Rate (APR): Effective Annual Interest Rate (EAR): *where MR = monthly interest rate 40

Effective Interest Rates Example: Given a monthly rate of 1%, what is the effective annual rate (EAR)? What is the annual percentage rate (APR)? 41

Effective Interest Rates Example: Given a monthly rate of 1%, what is the effective annual rate (EAR)? What is the annual percentage rate (APR)? 42
