Chapter Outcomes • What is the time value of money • Interest rate : Simple VS Compound • Calculation : Future Value, Present Value, Interest rate, Number of periods • Single Cash flow (FV, PV) • Annuities (FVA, PVA)
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ Time Value of Money • TIME VALUE OF MONEY: Interest is earned over time by saving or investing money
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ Time Value of Money • PRESENT VALUE (PV) • FUTURE VALUE (FV) • Interest rate (i) • Number of periods (n)
Simple Interest • Interest earned only on the principal • EQUATION: FV = PV + (PV x i x n) • EXAMPLE:You save $100 today and a bank pays you 10% per year. How much will be your savings after 2 years? 0 1 2 $100 FV2 = ??? PV +( PV x i x n ) 100 10% 2 100 = $ 120
Compound Interest • Interest earned on both principal and interest • EQUATION: FV = PV x (1 + i)n • EXAMPLE:You save $100 today and a bank pays you 10% per year. How much will be your savings after 2 years? 0 1 2 2 FV2 = ??? PV x ( 1 + i ) n 100 $100 10% = $ 121
Future Value $100 + $100(0.05) = $105 PV + Interest = FV PV + PV*i = FV PV = Present Value FV = Future Value i = interest rate (as a percentage)
Future Value Future Value in one year FV = PV*(1+i)
Future Value Future Value in two years $100+$100(0.05)+$100(0.05) + $5(0.05) =$110.25 Present Value of the Initial Investment + Interest on the initial investment in the 1st Year + Interest on the initial investment in the 2nd Year+ Interest on the Interest from the 1stYear in the 2nd Year = Future Value in Two Years
Future Value Future Value in n years FVn = PV*(1+i)n
Future Value is the value on some future date of an investment made today. Future Value (FV) Year 0 1 2 3 4 5……….. n 1 ?
Using Interest Factor Tables • FV = PV x FVIF i, nFVIFi,n = look from tableA1 • What is the future value of $100 invested now at 10% interest for 2 years? FV = PV x FVIF i, n FV = PV x FVIF10%, 2 FV = $100 x 1.21 = $121
Using Interest Factor Tables • FV = PV x FVIF i, nFVIFi,n = look from tableA1 • Ann deposits $250 today, how much is her account value after 7 years if the saving rate is 1%? • How much do you have to deposit today in order to have $50,000 in the next 4 years, saving rate is 2%? • Sam deposits $100 today and two years from now, he is going to deposit another $200. With 3% rate, how much is his account value 5 years from now?
Present Value Present Value (PV) is the value today (in the present) of a payment that is promised to be made in the future. OR Present Value is the amount that must be invested today in order to realize a specific amount on a given future date.
Present Value Present Value (PV) is the value today (in the present) of a payment that is promised to be made in the future. Year 0 1 2 3 4 5……….. n 1 ?
Present Value Present Value is the amount that must be invested today in order to realize a specific amount on a given future date. Year 0 1 2 3 4 5……….. n 1 ?
Discounting from FV to PV FV = PV x (1 + i)n FV = PV xFVIF i, n PV = FV ÷ (1 + i)n PV = FV x [1 ÷ (1 + i)n] PV = FV x PVIF i, n Table A1 Table A2 17
Practice : Using Table What is the present value of $1,000 to be received 10 years from now if the interest rate is 8%? PV = FV x PVIF i, n = FV x PVIF 8%, 10 = $1,000 x 0.463 = $463

Annuity Example: You save $100 at the end of each year for 3 years 2 3 0 n 1 $ 100 $ 100 $ 100 $$$ $$$ $$$ 20
Compound Annuities • Compound annuity involves depositing or investing an equal sum of money at the end of each year for a certain number of years and allowing it to grow. • Perhaps we are saving money for education, a new car or a vacation home. • In any case, we want to know how much savings will have grown by some point in the future.

More than 1 period per year • Interest rate per period → i ÷ m • Number of periods → n x m • Annually → m = 1 • Semiannually → m = 2 • Quarterly → m = 4 • Monthly → m = 12 • Daily → m = 365 * m = number of periods / year
Conclusion A1: FV = PV x FVIF i/m, nxm A2: PV = FV x PVIF i/m, nxm A3: FVA = PMT x FVIFA i/m, nxm A4: PVA = PMT x PVIFA i/m, nxm * i /m = Interest rate per period ** n x m = Number of periods
