What is the future value in one year? • Interest = 1, 000 × .05 = 50 • Value in one year = principal + interest = 1, 000 + 50 = 1, 050 • Future Value (FV) = 1, 000(1 + .05) = 1, 050 Suppose you leave the money in for another year. How much will you have two years from now? FV = 1, 000 × 1.05 × 1.05 = 1, 000 × 1.052 = 1, 102.50 Managerial Finance Time Value of Money Future Value 4 / 61 Future Values General Formula We have the formula you saw before: FV = PV(1 + r )t where FV future value PV present value r period interest rate, expressed as a decimal t number of periods The future value interest factor is the factor (1 + r )t Managerial Finance Time Value of Money Future Value 5 / 61 Compounding The process of reinvesting money and any interest earned for more than one period is called compounding. Compounding the interest means earning interest on interest. Consider the previous example: • FV with simple interest = 1,000 + 50 + 50 = 1,100 • FV with compound interest = 1,102.50 • The extra 2.50 comes from the interest of .05 × 50 = 2.50 earned on the first interest payment Managerial Finance Time Value of Money Future Value 6 / 61 Compounding How important is compounding? The effect of compounding is small for a small number of periods, but increases as the number of periods increases. In our example, with two periods we have a compound interest of $2.50 against a simple interest of $100 = $50 + $50. The compound interest is very small when compared to the simple interest. On the other hand, if we invest for 50 periods, the total simple interest amounts to $2, 500.00, while the compound interest is $7, 967.40. Managerial Finance Time Value of Money Future Value 7 / 61 Future Value as a general formula In fact the Future Value formula is applicable to more than just money quantities. For example, suppose your company expects to increase unit sales of widgets by 15% per year for the next 5 years. If you currently sell 3 million widgets in one year, how many widgets do you expect to sell in 5 years? FV = 3, 000, 000 × (1 + .15)5 = 6, 034, 072 Managerial Finance Time Value of Money Future Value 8 / 61 Time Value of Money Future Value Present Values Discount Rate Discounted Cash Flow Valuation Future and Present Values of Multiple Cash Flows Valuing Level Cash Flows Annuities and Perpetuities The Effect of Compounding Loan Types and Loan Amortization Present Value How much do we have to invest today to have some amount in the future? FV = PV(1 + r )t Rearrange to solve for PV = FV (1 + r )t When we talk about discounting, we mean finding the present value PV of some future amount. By the “value” of something, we mean the present value unless we specifically indicate that we want the future value. Managerial Finance Time Value of Money Present Values 10 / 61 Present Value Example You want to begin saving for your daughter’s college education and you estimate that she will need $150,000 in 17 years. If you feel confident that you can earn 8% per year, how much do you need to invest today? PV = Managerial Finance 150, 000 = $40, 540.34 (1 + .08)17 Time Value of Money Present Values 11 / 61 Present Value Important Relationship I For a given interest rate – the longer the time period, the lower the present value. Example: What is the present value of $500 to be received in 5 years? 10 years? The discount rate is 10% • 5 years: PV = 500/(1 + .1)5 = 310.46 • 10 years: PV = 500/(1 + .1)10 = 192.77 Managerial Finance Time Value of Money Present Values 12 / 61 Present Value Important Relationship II For a given time period – the higher the interest rate, the smaller the present value Example: What is the present value of $500 received in 5 years if the interest rate is 10%? 15%? • 10% rate: PV = 500/(1 + .1)5 = 310.46 • 15% rate: PV = 500/(1 + .15)5 = 248.59 Managerial Finance Time Value of Money Present Values 13 / 61 Present Value All the moving parts The PV formula PV = FV (1 + r )t has four parts: PV, FV, r , and t If we know any three, we can solve for the fourth. For example, r= Managerial Finance Time Value of Money FV PV 1 t −1 Present Values 14 / 61 Time Value of Money Future Value Present Values Discount Rate Discounted Cash Flow Valuation Future and Present Values of Multiple Cash Flows Valuing Level Cash Flows Annuities and Perpetuities The Effect of Compounding Loan Types and Loan Amortization Discount Rate The quantity used in the PV formula 1 (1 + r )t is usually called the discount factor and the rate r the discount rate. Calculating the present value of a future cash flow to determine its value today is called the discounted cash flow valuation (DCF). Managerial Finance Time Value of Money Discount Rate 16 / 61 Discount Rate Examples You are looking at an investment that will pay $1,200 in 5 years if you invest $1,000 today. What is the implied rate of interest? r= 1, 200 1, 000 1/5 − 1 = .03714 = 3.714% Suppose you are offered an investment that will allow you to double your money in 6 years. You have $10,000 to invest. What is the implied rate of interest? r= Managerial Finance 20, 000 10, 000 1/6 Time Value of Money − 1 = .122462 = 12.25% Discount Rate 17 / 61 Finding the Number of Periods Start with the basic equation FV = PV(1 + r )t and solve for t (remember your logs1 ): t = log FV PV / log(1 + r ) You can use the financial keys on the calculator as well; just remember the sign convention. 1 here log means the natural log function. In Excel, this is given by LN Managerial Finance Time Value of Money Discount Rate 18 / 61 Finding the Number of Periods Example You want to purchase a new car, and you are willing to pay $20,000. If you can invest at 10% per year and you currently have $15,000, how long will it be before you have enough money to pay cash for the car? 20, 000 / log(1 + .1) = 3.02 years t = log 15, 000 Managerial Finance Time Value of Money Discount Rate 19 / 61 Finding the Number of Periods Example Suppose you want to buy a new house. You currently have $15,000, and you figure you need to have a 10% down payment plus an additional 5% of the loan amount for closing costs. Assume the type of house you want will cost about $150,000 and you can earn 7.5% per year. How long will it be before you have enough money for the down payment and closing costs? How much do you need to have in the future? • Down payment = .1 × 150, 000 = 15, 000 • Closing costs = .05 × (150, 000 − 15, 000) = 6, 750 • Total needed = 15, 000 + 6, 750 = 21, 750 Compute the number of periods using the formula: t = log(21, 750/15, 000)/ log(1 + .075) = 5.14 years Managerial Finance Time Value of Money Discount Rate 20 / 61 Using Excel for Time Value of Money Computations Use the following formulas for TVM calculations: • FV(rate,nper,pmt,pv) – future value • PV(rate,nper,pmt,fv) – present value • RATE(nper,pmt,pv,fv) – discount rate • NPER(rate,pmt,pv,fv) – number of periods where rate interest rate nper number of periods pmt equals zero pv present value fv future value The formula icon in Excel is very useful when you can’t remember the exact formula! Managerial Finance Time Value of Money Discount Rate 21 / 61 Time Value of Money Future Value Present Values Discount Rate Discounted Cash Flow Valuation Future and Present Values of Multiple Cash Flows Valuing Level Cash Flows Annuities and Perpetuities The Effect of Compounding Loan Types and Loan Amortization Multiple Cash Flows Future Value You think you will be able to deposit $4,000 at the end of each of the next three years in a bank account paying 8 percent interest. You currently have $7,000 in the account. How much will you have in three years? How much will you have in four years? Find the value at year 3 of each cash flow and add them together: • Today (year 0): FV = 7000 × (1.08)3 = 8, 817.98 • Year 1: FV = 4, 000 × (1.08)2 = 4, 665.60 • Year 2: FV = 4, 000 × (1.08) = 4, 320 • Year 3: FV = 4, 000 Thus, the total value in 3 years is 8, 817.98 + 4, 665.60 + 4, 320 + 4, 000 = 21, 803.58. The value at year 4 is simply 21, 803.58 × (1.08) = 23, 547.87 Managerial Finance Discounted Cash Flow Valuation Future and Present Values 23 / 61 Multiple Cash Flows Future Value Suppose you invest $500 in a mutual fund today and $600 in one year. If the fund pays 9% annually, how much will you have in two years? FV = 500 × (1.09)2 + 600 × (1.09) = 1, 248.05 How much will you have in 5 years if you make no further deposits? First way: FV = 500 × (1.09)5 + 600 × (1.09)4 = 1, 616.26 Second way – use the value at year 2: FV = 1, 248.05 × (1.09)3 = 1, 616.26 Managerial Finance Discounted Cash Flow Valuation Future and Present Values 24 / 61 Multiple Cash Flows Future Value To calculate the future value of multiple cash flows, we can roll them forward one year at a time using the interest rate, or, in a more direct way, look at how many years we need to compound each cashflow and apply the interest rate that many times. today Managerial Finance 1 2 Discounted Cash Flow Valuation n Future and Present Values time 25 / 61 Multiple Cash Flows Present Value You are considering an investment that will pay you $1,000 in one year, $2,000 in two years, and $3,000 in three years. If you want to earn 10% on your money, how much would you be willing to pay? • PV = 1000/(1.1)1 = 909.09 • PV = 2000/(1.1)2 = 1, 652.89 • PV = 3000/(1.1)3 = 2, 253.94 • PV = 909.09 + 1, 652.89 + 2, 253.94 = 4, 815.92 or, looking at the PV of cash flows at each period: • Present Value of at year 3: PV3 = 3, 000 • Present Value of at year 2: PV2 = 3, 000/1.1 + 2, 000 = 4, 727.27 • Present Value of at year 1: PV1 = 4, 727.27/1.1 + 1, 000 = 5, 297.52 • Present Value of cash flows today: PV = 5, 297.52/1.1 = 4, 815.93 Managerial Finance Discounted Cash Flow Valuation Future and Present Values 26 / 61 Multiple Cash Flows Present Value That is, just like for Future Value, we calculate the present value of multiple cash flows by rolling them backwards one year at a time using the interest rate, or, in a more direct way, discount by the amount of years. today Managerial Finance 1 2 Discounted Cash Flow Valuation n Future and Present Values time 27 / 61 Multiple Cash Flows Present Value You are offered the opportunity to put some money away for retirement. You will receive five annual payments of $25,000 each beginning in 40 years. How much would you be willing to invest today if you desire an interest rate of 12%? • Cash flows in years 0 – 39 are zero. • Cash flows in years 40 – 44 are $25K. Thus, PV = sum of all Present Values = $1, 084.71 Managerial Finance Discounted Cash Flow Valuation Future and Present Values 28 / 61 Time Value of Money Future Value Present Values Discount Rate Discounted Cash Flow Valuation Future and Present Values of Multiple Cash Flows Valuing Level Cash Flows Annuities and Perpetuities The Effect of Compounding Loan Types and Loan Amortization Annuities and Perpetuities An annuity is a finite series of equal payments that occur at regular intervals. If the first payment occurs at the end of the period, it is called an ordinary annuity. If the first payment occurs at the beginning of the period, it is called an annuity due. A perpetuity is an infinite series of equal payments. Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 30 / 61 Annuities Present Value For an ordinary annuity, instead of having to sum multiple cash-flows, we can use the following formula 1 1 − (1+r )t PV = C × r where C amount paid every period t periods r interest rate Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 31 / 61 Annuities Future Value The formula on the previous slide can be reworked to give the future value: FV = C × (1 + r )t − 1 r where C amount paid every period t periods r interest rate Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 32 / 61 Perpetuities Present Value For perpetuities there is no Future Value computation (since it’s a perpetual), but we can compute the Present Value as: C PV = r where C amount paid every period r interest rate Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 33 / 61 Annuities Present Value Suppose you win the Publishers Clearinghouse $10 million sweepstakes. The money is paid in equal annual installments of $333,333.33 over 30 years. If the appropriate discount rate is 5%, how much is the sweepstakes actually worth today? Using the present value formula for an annuity, PV = 333, 333.33 × Managerial Finance 1 1 − 1.05 30 .05 Valuing Level Cash Flows ! = $5, 124, 150.29 Annuities and Perpetuities 34 / 61 Annuities Present Value You are ready to buy a house, and you have $20,000 for a down payment and closing costs. Closing costs are estimated to be 4% of the loan value. You have an annual salary of $36,000, and the bank is willing to allow your monthly mortgage payment to be equal to 28% of your monthly income. The interest rate on the loan is 6% per year with monthly compounding (.5% per month) for a 30-year fixed rate loan. • How much money will the bank loan you? • How much can you offer for the house? Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 35 / 61 Annuities Present Value • Bank loan • Monthly income = 36, 000/12 = 3, 000 • Maximum payment = .28 × 3, 000 = 840 30×12 = 140, 105 • PV = 840 1−1/1.005 .005 • Total Price • Closing costs = .04 × 140, 105 = 5, 604 • Down payment = 20, 000 − 5, 604 = 14, 396 • Total Price = 140, 105 + 14, 396 = 154, 501 Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 36 / 61 Annuities Finding the Payment Amount Suppose you want to borrow $20,000 for a new car. You can borrow at 8% per year, compounded monthly (8%/12 = .66667% per month). If you take a 4 year loan, what is your monthly payment? 20, 000 = C × 1 1 − 1.0066667 48 .0066667 ! Solving leads to C = $488.26. Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 37 / 61 Annuities Number of Payments Suppose you borrow $2,000 at 5%, and you are going to make annual payments of $734.42. How long before you pay off the loan? 2, 000 = 734.42 × 1 − 1/1.05t /.05 Solving, .136161869 = 1 − 1/1.05t , which leads to 1.157624287 = 1.05t . Finally, t = log(1.157624287)/ log(1.05) = 3 years Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 38 / 61 Annuities Finding the rate Suppose you borrow $10,000 from your parents to buy a car. You agree to pay $207.58 per month for 60 months. What is the monthly interest rate? 10, 000 = 207.58 × 1 − 1/(1 + r )60 /r We can use the RATE in Excel, use the Solver feature, or even proceed by trial-and-error: • Choose an interest rate and compute the PV of the payments based on this rate • Compare the computed PV with the actual loan amount • If the computed PV > loan amount, then the interest rate is too low • If the computed PV < loan amount, then the interest rate is too high • Adjust the rate and repeat the process until the computed PV and the loan amount are equal Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 39 / 61 Annuities Future Values Suppose you begin saving for your retirement by depositing $2,000 per year in an IRA at the end of every year. If the interest rate is 7.5%, how much will you have in 40 years? FV = 2, 000(1.07540 − 1)/.075 = $454, 513.04 What if you deposit the $2,000 at the beginning of every year, starting today? The value of an annuity due is such that Annuity due value = Ordinary annuity value × (1 + r ) This is because every cash flow for an annuity due has one more year to earn interested when compared to those of an ordinary annuity. Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 40 / 61 Annuities and Perpetuities Summary of Formulas Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 41 / 61 Example of a Perpetuity Preferred Stock Preferred stock (or preference stock) is a type of stock corporations sell to investors. The investor is typically promised a fixed cash dividend every period forever2 . This dividend must be paid before any dividend can be paid to regular stockholders. Because the PV of a perpetuity is PV = Cr , if for example a company wants to raise $10M by issuing preferred stock, and the required return from investors is 5% annually, then it needs to pay out dividends in the amount of C = PV ×r = 10, 000, 000 × 5% = $500, 000 2 there are some less common issues of preferred stock with long maturities that are not perpetual Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 42 / 61 Growing Annuities Present Value Some annuities have payments that grow over time at a fixed rate g. The present value for such annuities is t 1 − 1+g 1+r PV = C × r −g where C amount paid every period t periods r interest rate g rate at which payments grow Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 43 / 61 Growing Perpetuity Present Value As for annuities, the present value formula for a Perpetuity with growing payments at a rate g is C PV = r −g where C amount paid every period r interest rate g rate at which payments grow Managerial Finance Valuing Level Cash Flows Annuities and Perpetuities 44 / 61 Growing Annuities Example A defined-benefit retirement plan offers to pay $20,000 per year for 40 years and increase the annual payment by three-percent each year. What is the present value at retirement if the discount rate is 10 percent? 1− PV = 20, 000 × Managerial Finance 1+.03 1+.10 40 .10 − .03 Valuing Level Cash Flows = $265, 121.57 Annuities and Perpetuities 45 / 61 Effective Annual Rate (EAR) The Effective Annual Rate (EAR) is the actual rate paid (or received) after accounting for compounding that occurs during the year. If you want to compare two alternative investments with different compounding periods, you need to compute the EAR and use that for comparison. For example, if you are paid 1% every month then in one year $100 would grow to $100 × (1 + .01)12 = $112.68 = $100 + $12.68 Thus, your EAR is 12.68%. Managerial Finance The Effect of Compounding 46 / 61 Annual Percentage Rate (APR) The Annual Percentage Rate (APR) is the annual rate that is quoted by law. By definition, APR = period rate × number of periods per year Consequently, to get the period rate we just rearrange the APR equation: period rate = APR number of periods per year Note that you should never divide the effective annual rate by the number of periods per year – it will not give you the period rate. Managerial Finance The Effect of Compounding 47 / 61 Annual Percentage Rate (APR) Examples What is the APR if the monthly rate is .5%? .5% × 12 = 6% What is the APR if the semiannual rate is .5%? .5% × 2 = 1% What is the monthly rate if the APR is 12% with monthly compounding? 12%/12 = 1% Managerial Finance The Effect of Compounding 48 / 61 Annual Percentage Rate (APR) Things to Remember You always need to make sure that the interest rate and the time period match. • If you are looking at annual periods, you need an annual rate. • If you are looking at monthly periods, you need a monthly rate. If you have an APR based on monthly compounding, you have to use monthly periods for lump sums, or adjust the interest rate appropriately if you have payments other than monthly. Managerial Finance The Effect of Compounding 49 / 61 Effective Annual Rate (EAR) Examples Suppose you can earn 1% per month on $1 invested today. • What is the APR? 1% × 12 = 12% • How much are you effectively earning? FV = 1 × (1.01)12 = $1.1268 • Rate = (1.1268 − 1)/1 = .1268 = 12.68% Managerial Finance The Effect of Compounding 50 / 61 Effective Annual Rate (EAR) Examples Suppose if you put it in another account, you earn 3% per quarter. • What is the APR? 3% × 4 = 12% • How much are you effectively earning? FV = 1 × (1.03)4 = 1.1255 • Rate = (1.1255 − 1)/1 = .1255 = 12.55% Managerial Finance The Effect of Compounding 51 / 61 EAR and APR The following formula allows one to convert APR into EAR: EAR = 1 + APR m m −1 where m number of times interest is paid annually Managerial Finance The Effect of Compounding 52 / 61 EAR and APR Decision Making You are looking at two savings accounts. One pays 5.25%, with daily compounding. The other pays 5.3% with semiannual compounding. Which account should you use? • First account: EAR = (1 + .0525/365)365 − 1 = 5.39% • Second account: EAR = (1 + .053/2)2 − 1 = 5.37% Which account should you choose and why? Managerial Finance The Effect of Compounding 53 / 61 EAR and APR Decision Making Let’s verify the choice. Suppose you invest $100 in each account. How much will you have in each account in one year? • First account: • Daily rate = .0525/365 = .00014383562 • FV = 100 × (1.00014383562)365 = $105.39 • Second account: • Daily rate = .0539/2 = .0265 • FV = 100 × (1.0265)2 = $105.37 You have more money in the first account. Managerial Finance The Effect of Compounding 54 / 61 EAR and APR To convert EAR into APR, 1 APR = m (1 + EAR) m − 1 where m number of times interest is paid annually For example, suppose you want to earn an effective rate of 12% and you are looking at an account that compounds on a monthly basis. What APR must they pay? 1 APR = 12 × (1 + .12) 12 − 1 = .1139 = 11.39% Managerial Finance The Effect of Compounding 55 / 61 Computing Payments with APRs Suppose you want to buy a new computer system and the store is willing to allow you to make monthly payments. The entire computer system costs $3,500. The loan period is for 2 years, and the interest rate is 16.9% with monthly compounding. What is your monthly payment? • Monthly rate = .169/12 = .01408333333 • Number of months = 2 × 12 = 24 • 3, 500 = C × 1 − (1/1.01408333333)24 /.01408333333 • C = 172.88 Managerial Finance The Effect of Compounding 56 / 61 Continuous Compounding Sometimes investments or loans are figured based on continuous compounding EAR = exp(q) − 1 where exp is is the exponential function. In Excel, use the EXP function to compute the formula above. Example: What is the effective annual rate of 7% compounded continuously? EAR = exp(.07) − 1 = .0725 = 7.25% Managerial Finance The Effect of Compounding 57 / 61 Pure Discount Loans A pure discount loan is the simplest form of loan. The borrower receives money today and repays a single lump sum at some time in the future. To get the PV of such a loan, just compute the discounted value of the single lump sum payment in the future. Treasury bills (or T-bills) are excellent examples of pure discount loans. A T-bill is a promise by the government to repay a fixed amount at some time in the future – for example, 3 months or 12 months – without any periodic interest payments. Managerial Finance Loan Types and Loan Amortization 58 / 61 Interest-Only Loans In an interest-only loan, the borrower pays interest each period and repays the entire principal (the original loan amount) at some point in the future. For example, consider a 5-year, interest-only loan with a 7% interest rate. The principal amount is $10,000, and interest is paid annually. What would the stream of cash flows be? • Years 1 – 4: Interest payments of .07 × 10, 000 = 700 • Year 5: Interest + principal = 10, 700 This cash flow stream is similar to the cash flows on corporate bonds, and we will talk about them in greater detail later. Managerial Finance Loan Types and Loan Amortization 59 / 61 Amortized Loans Unlike a pure discount or interest-only loan, when the principal is repaid all at once, an amortized loan is such that the lender receives part of the loan amount over time. The process of providing for a loan to be paid off by making regular principal reductions is called amortizing the loan. For example, consider a $50,000, 10 year loan at 8% interest. The loan agreement requires the firm to pay $5,000 in principal each year plus interest for that year. Each payment covers the interest expense plus reduces principal. The table on the next slide shows an amortization schedule and payments for such a loan.
