Foundations of FinanceArthur J. Keown John D. MartinJ. William Petty David F. Scott, Jr. Chapter 5 The Time Value of Money
Learning Objectives • Explain the mechanics of compounding, which is how money grows over a time when it is invested. • Be able to move money through time using time value of money tables, financial calculators, and spreadsheets. • Discuss the relationship between compounding and bringing money back to present. Foundations of Finance
Learning Objectives • Define an ordinary annuity and calculate its compound or future value. • Differentiate between an ordinary annuity and an annuity due and determine the future and present value of an annuity due. • Determine the future or present value of a sum when there are nonannual compounding periods. Foundations of Finance
Learning Objectives • Determine the present value of an uneven stream of payments • Determine the present value of a perpetuity. • Explain how the international setting complicates the time value of money. Foundations of Finance
Principles Used in this Chapter • Principle 2: The Time Value of Money – A Dollar Received Today Is Worth More Than a Dollar Received in The Future. Foundations of Finance
Simple Interest Interest is earned on principal $100 invested at 6% per year 1st year interest is $6.00 2nd year interest is $6.00 3rd year interest is $6.00 Total interest earned: $18.00 Foundations of Finance
Compound Interest • When interest paid on an investment during the first period is added to the principal; then, during the second period, interest is earned on the new sum. Foundations of Finance
Compound Interest Interest is earned on previously earned interest $100 invested at 6% with annual compounding 1st year interest is $6.00 Principal is $106.00 2nd year interest is $6.36 Principal is $112.36 3rd year interest is $6.74 Principal is $119.11 Total interest earned: $19.11 Foundations of Finance
Future Value - The amount a sum will grow in a certain number of years when compounded at a specific rate. Foundations of Finance
Future Value FV1 = PV (1 + i) Where FV1 = the future of the investment at the end of one year i= the annual interest (or discount) rate PV = the present value, or original amount invested at the beginning of the first year Foundations of Finance
Future Value What will an investment be worth in 2 years? $100 invested at 6% FV2= PV(1+i)2 =$100 (1+.06)2 $100 (1.06)2 = $112.36 Foundations of Finance
Future Value • Future Value can be increased by: • Increasing number of years of compounding • Increasing the interest or discount rate Foundations of Finance
Future Value Using Tables FVn = PV (FVIFi,n) Where FVn = the future of the investment at the end of n year PV = the present value, or original amount invested at the beginning of the first year FVIF = Future value interest factor or the compound sum of $1 i= the interest rate n= number of compounding periods Foundations of Finance
Future Value What is the future value of $500 invested at 8% for 7 years? (Assume annual compounding) Using the tables, look at 8% column, 7 time periods. What is the factor? FVn= PV (FVIF8%,7yr) = $500 (1.714) = $857 Foundations of Finance
Future Value Using Calculators Using any four inputs you will find the 5th. Set to P/YR = 1 and END mode. INPUTS OUTPUT N 10 I/YR 6 -100 PV 0 PMT FV 179.10 Foundations of Finance
Future Value Using Spreadsheets Foundations of Finance
Present Value The current value of a future payment PV= FVn {1/(1+i)n} Where FVn = the future of the investment at the end of n years n= number of years until payment is received i= the interest rate PV = the present value of the future sum of money Foundations of Finance
Present Value What will be the present value of $500 to be received 10 years from today if the discount rate is 6%? PV = $500 {1/(1+.06)10} = $500 (1/1.791) = $500 (.558) = $279 Foundations of Finance
Present Value Using Tables PVn = FV (PVIFi,n) Where PVn = the present value of a future sum of money FV = the future value of an investment at the end of an investment period PVIF = Present Value interest factor of $1 i= the interest rate n= number of compounding periods Foundations of Finance
Present Value What is the present value of $100 to be received in 10 years if the discount rate is 6%? PVn = FV (PVIF6%,10yrs.) = $100 (.558) = $55.80 Foundations of Finance
Present Value Using Calculators Using any four inputs you will find the 5th. Set to P/YR = 1 and END mode. INPUTS OUTPUT N 10 PV -55.84 I/YR 6 PMT 0 FV 100.00 Foundations of Finance
Annuity • Series of equal dollar payments for a specified number of years. • Ordinary annuity payments occur at the end of each period Foundations of Finance
Compound Annuity • 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. Foundations of Finance
Compound Annuity FV5 = $500 (1+.06)4 + $500 (1+.06)3 +$500(1+.06)2 + $500(1+.06) + $500 = $500 (1.262) + $500 (1.191) + $500 (1.124) + $500 (1.090) + $500 = $631.00 + $595.50 + $562.00 + $530.00 + $500 = $2,818.50 Foundations of Finance

Future Value of an Annuity FV= PMT {(FVIFi,n-1)/ i } Where FV n= the future of an annuity at the end of the nth years FVIFi,n= future-value interest factor or sum of annuity of $1 for n years PMT= the annuity payment deposited or received at the end of each year i= the annual interest (or discount) rate n = the number of years for which the annuity will last Foundations of Finance
Compounding Annuity What will $500 deposited in the bank every year for 5 years at 10% be worth? FV= PMT {(FVIFi,n-1)/ i } Simplified this equation is: FV5 = PMT(FVIFAi,n) = $500(5.637) = $2,818.50 Foundations of Finance
Future Value of an Annuity Using Calculators Using any four inputs you will find the 5th. Set to P/YR = 1 and END mode. INPUTS OUTPUT N 5 FV -2,818.55 PV 0 I/YR 6 PMT 500 Foundations of Finance
Present Value of an Annuity • Pensions, insurance obligations, and interest received from bonds are all annuities. These items all have a present value. • Calculate the present value of an annuity using the present value of annuity table. Foundations of Finance
Present Value of an Annuity Calculate the present value of a $500 annuity received at the end of the year annually for five years when the discount rate is 6%. PV = PMT(PVIFAi,n) = $500(4.212) = $2,106 Foundations of Finance
Annuities Due • Ordinary annuities in which all payments have been shifted forward by one time period. Foundations of Finance
Amortized Loans • Loans paid off in equal installments over time • Typically Home Mortgages • Auto Loans Foundations of Finance
Payments and Annuities If you want to finance a new machinery with a purchase price of $6,000 at an interest rate of 15% over 4 years, what will your payments be? Foundations of Finance
Future Value Using Calculators Using any four inputs you will find the 5th. Set to P/YR = 1 and END mode. INPUTS OUTPUT N 4 PMT -2,101.59 PV 6,000 I/YR 15 FV 0 Foundations of Finance
Amortization of a Loan • Reducing the balance of a loan via annuity payments is called amortizing. • A typical amortization schedule looks at payment, interest, principal payment and balance. Foundations of Finance
Amortization Schedule Foundations of Finance
Compounding Interest with Non-annual periods If using the tables, divide the percentage by the number of compounding periods in a year, and multiply the time periods by the number of compounding periods in a year. Example: 8% a year, with semiannual compounding for 5 years. 8% / 2 = 4% column on the tables N = 5 years, with semiannual compounding or 10 Use 10 for number of periods, 4% each Foundations of Finance
Perpetuity • An annuity that continues forever is called perpetuity • The present value of a perpetuity is PV = PP/i PV = present value of the perpetuity PP = constant dollar amount provided by the of perpetuity i = annuity interest (or discount rate) Foundations of Finance
The Multinational Firm • Principle 1- The Risk Return Tradeoff – We Won’t Take on Additional Risk Unless We Expect to Be Compensated with Additional Return • The discount rate is reflected in the rate of inflation. • Inflation rate outside US difficult to predict • Inflation rate in Argentina in 1989 was 4,924%, in 1990 dropped to 1,344%, and in 1991 it was only 84%.
