4.3 Other parameters

4.4 Multiple cash flows

4.5 Comparing rates

4.6 Loan types

### Definitions

• Present value (PV): earlier money on a time line.

• Future value (FV): later money on a time line.

• Interest rate (i), e.g., discount rate, required rate, cost of capital: exchange rate between earlier money and later money.

• The number of time periods on a time line (N).

• PV  FV: “time value of money” via the exchange rate, i.e., interest rate, i.

### End-of-period cash flows

• By default, in this class cash flows occur at the end of each period.

• If cash flows occur at the beginning of each period, it will be explicitly specified.

### One equation; one solution

• In general, we have one equation: 0 = f (PV, FV, i, N).

• Since we have only one equation, we can only allow for one unknown parameter (variable). That is, if we’d like to calculate the value of a parameter, say FV, the values of the remaining parameters, i.e., PV, i, and N, need to be known.

### FV example I

• Suppose that we buy a 12-month CD at 12% annual interest rate for \$10,000.

• FV = PV  (1 + i)N = \$10,000  (1 + 12%)1 = \$11,200.

### Do not compare apples with oranges

• Why N = 1 while the CD matures in 12 months? The key is that:

• The time frequency of i and N must be the same.

• If we use annual interest rate, then we need to measure the investment period using the unit of year. In this case, 12 months equal a year; so N = 1.

• What is the value of N if the example provided us monthly interest rate, say 0.96% per month?

• Any volunteer?

### Compounding

• Of course, the previous formula, FV = PV  (1 + i)N, is based on the notion of compounding.

• Compounding: the process of accumulating interest on an investment over time to earn more interest.

• Earn interest on interest.

• Reinvest the interest.

• A popular method.

### FV example II

• Deposit \$50,000 in a bank account paying 5%. How much will you have in 6 years?

• Formula: FV = PV  (1 + i)N = \$50,000  (1 + 5%)6 = \$67,000.

• Financial table (Table A.3): FV = \$50,000  1.3401 = \$67,000.

• Financial calculator: 6 N; 5 I/Y; 50000 PV; CPT FV. The answer is FV = -67,004.7820. Ignore the negative sign.

### Texas Instruments BAII Plus (keys)

• FV: future value.

• PV: present value.

• I/Y: period interest rate.

• Interest is entered as a percent.

• N = number of time periods.

• Clear the registers (CLR TVM, i.e., 2nd FV) after each calculation; otherwise, your next calculation may come up with a wrong answer.

### FV example, III

• Jacob invested \$1,000 in the stock of IBM. IBM pays a current dividend of \$2 per share, which is expected to grow by 20% per year for the next 2 years. What will the dividend of IBM be after 2 years?

• Formula: FV = PV  (1 + i)N = \$2  (1 + 20%)2 = \$2.88.

• Table A.3: FV = \$2  1.4400 = \$2.88.

• Calculator: 2 PV; 20 I/Y; 2 N; CPT FV. The answer is -2.8800.

### Discounting

• Discounting: the process of calculating the present value of future cash flows.

• We call i the discount rate when we try to solve for present value. Depending on the question, this rate can be interest rate, cost of capital, or opportunity cost.

### PV example, I

• Suppose that you need \$4,000 to pay your tuition. 1-year CD interest rate is 7%. How much do you need to put up today?

• Formula: PV = FV / (1 + i)N = \$4,000 / (1 + 7%)1 = \$3,738.3.

• Table A.1: PV = \$4,000  0.9346 = \$3,738.4.

• Calculator: 4000 FV; 7 I/Y; 1 N; CPT PV. The answer is -3,738.3178.

### PV example, II

• Suppose that you are 21 years old. Your annual discount (return) rate is 10%. How much do you need to invest today in order to reach \$1 million by the time you reach 65?

• Formula: PV = FV / (1 + i)N = \$1,000,000 / (1 + 10%)44 = \$15,091.

• Table A.1 does not have the present value factor for N = 44. This is the limitation of using a financial table. Thus, we will focus on the other 2 methods in the following discussions.

• Calculator: 1000000 FV; 10 I/Y; 44 N; CPT PV. The answer is -15,091.1332.

### PV relationship, I

• Holding interest rate constant – the longer the time period, the lower the PV.

• What is the present value of \$5,000 to be received in 5 years? 10 years? The discount rate is 8%

• 5 years: 5 N; 8 I/Y; 5000 FV; CPT PV. The answer is PV = -3,402.9160.

• 10 years: 10 N; 8 I/Y; 5000 FV; CPT PV. The answer is PV = -2,315.9674.

### PV relationship, II

• Holding time period constant – the higher the interest rate, the smaller the PV.

• What is the present value of \$5,000 received in 5 years if the interest rate is 10%? 15%?

• 10%: 10 I/Y; 5 N; 5000 FV; CPT PV. The answer is PV = -3,104.6066.

• 15%: 15 I/Y; 5 N; 5000 FV; CPT PV. The answer is PV = -2,485.8837.

### The other parameters

• Recall that 0 = f (PV, FV, i, N).

• We can find the value of i or N as long as we know about the values of the other parameters.

• The easiest way is to use a financial calculator.

• They are formulas, i.e., analytical solutions, for i and N as well. But these are not the focus of the course.

### Interest rate example

• Suppose that you deposit \$5,000 today in a bank account paying interest rate i per year. If you reach \$10,000 in 10 years, what rate of return are you being offered?

• Calculator: 5000 PV; -10000 FV; 10 N; CPT I/Y. The answer is I/Y = 7.1773.

• Note that for entering -10000 FV, this is the sequence: 10000 +/– FV.

### Time period example

• Suppose that you have \$10,000 today. You want to retire as a millionaire. The annual rate of return that you can earn on the market is 10%. In how many years can you retire?

• Calculator: 10000 PV; -1000000 FV; 10 I/Y; CPT N. The answer is: N = 48.3177.

### Multiple cash flows

• When there are multiple cash flows need to be discounted or compounded, the PV or FV of multiple cash flows are simply the sum of individual PV’s or FV’s, respectively.

### Multiple cash flow example

• Dennis has won the Kentucky State Lottery and will receive \$2,000 (cash flow 1)in a year and \$5,000 (cash flow 2) in 2 years. Dennis can earn 6% in his money market account, so the appropriate discount rate is 6%.

• PV = PV1 + PV2 = \$2,000 / (1 + 6%)1 + \$5,000 / (1 + 6%)2 = \$6,337.

• That is, Dennis is equally inclined toward receiving \$6,337 today and receiving \$2,000 and \$5,000 over the next 2 years.

### Annuity

• (Ordinary) Annuity: a level of stream of cash flows for a fixed period of time (multiple, equal cash flows).

• Same dollar amount per period, making calculation much easier.

• FV = C { [ (1 + i)N – 1] / i }.

• PV = C { [ 1 – 1 / (1 + i)N ] / i }.

• C is the fixed periodical payment.

### Annuity PV example

• Suppose that you want to buy a car. You can afford to pay \$632 per month for the next 48 months. You borrow at 1% per month for 48 months. How much can you borrow?

• Formula: PV = C { [ 1 – 1 / (1 + i)N ] / i } = \$632  { [ 1 – 1 / (1 + 1%)48 ] / 1%} = \$24,000.

• Calculator: 632 PMT; 1 I/Y; 48 N; CPT PV. The answer is: PV = -23,999.5424.

• In the solution manual (textbook), PVIFA(PVIA) stands for the PV of an annuity.

• PVIFA(i,N) = [ 1 – 1 / (1 + i)N ] / i .

### Let’s work on this

• Questions and Problems #28

### Annuity FV example

• Suppose that you put \$3,000 per year into a Roth IRA. The account pays 6% per year. How much will you have when you retire in 30 years?

• Formula: FV = C { [ (1 + i)N – 1] / i } = \$3,000  { [ (1 + 6%)30 – 1] / 6%} = \$237,174.56.

• Calculator: 3000 PMT; 6 I/Y; 30 N; CPT FV. The answer is: FV = -237,174.5586.

### Other parameters for annuity

• An insurance company offers to pay you \$10,000 per year for 10 years if you will pay \$67,100 up front. What is the rate of return?

• Calculator: -67100 PV; 10000 PMT; 10 N; CPT I/Y. The answer is: I/Y = 8.0003.

### Annuity due

• Annuity due: an annuity for which the cash flows occur at the beginning of the period.

• For calculating PV and FV of an annuity due, we can use the following formula: Annuity due value = ordinary annuity value  (1 + i).

### Annuity due example

• You are going to rent an apartment for a year. You have 2 choices: (1) pay the monthly rent, \$500, at the beginning of the month, or (2) pay the entire year’s rent, \$5,000, today. Suppose that you can earn 1% every month. Which is the better choice?

• Ordinary PV: 500 PMT; 1 I/Y; 12 N; CPT PV. The answer is: PV = -5,627.5387.

• Annuity due PV = ordinary PV  (1 + i) = \$5,627.5387  1.01 = \$5,683.8141.

• You would want to pay \$5,000 today if you can.

### Growing annuity

• Growing annuity: a finite number of growing cash flows, where the constant growth rate is g.

• PV = C { [ 1 – ((1 + g) / (1 + i))N ] / (i – g) }.

### Growing annuity example

• Emily has just been offered a job at \$80,000 a year. She anticipates her salary increasing by 9% a year until her retirement in 40 years. Given an interest rate of 20%, what is the present value of her lifetime salary?

• PV = C { [ 1 – ((1 + g) / (1 + i))N ] / (i – g) } = \$80,000  { [ 1 – ((1 + 9%) / (1 + 20%))40 ] / (20% – 9%) } = \$711,730.71.

### Perpetuity

• Perpetuity: a constant stream of cash flows without end.

• PV = C / i.

### Perpetuity example

• Preferred stock promises the buyer a fixed cash dividend every period (usually every quarter) forever. Suppose that VTinsurance Inc. wants to sell preferred stock. The quarterly dividend is \$1 per share. The required rate of return for this issue is 2.5% per quarter. What is the fair value of this issue?

• PV = C / i = \$1 / 2.5% = \$40 (per share).

### Growing perpetuity

• Growing perpetuity: an infinite cash flow stream that grows at a constant rate, g.

• PV = C1 / (i – g), C1 is the cash flow at time 1.

### Growing perpetuity example

• Toyota is expected to pay a dividend (annual dividend) of \$3 per share in a year. Investors also anticipate that the annual dividend will rise by 6% per year forever. The applicable discount rate is 11%. What is the present value of future dividends?

• PV = C1 / (i – g) = \$3 / (11% – 6%) = \$60 per share.

### Comparing rates, I

• Rates are quoted in many different ways.

• Legislation.

• Effective annual rate (EAR): the actual rate paid (or received) after accounting for compounding that occurs during the year.

• When comparing two alternative investments with different compounding frequencies, one needs to compute the EARs and use them for reaching a decision.

### Comparing rates, II

• Annual percentage rate (APR) or stated annual interest rate (SAIR): the annual rate without consideration of compounding.

• APR = period rate  the number of periods per year, m.

• EAR = [1 + (APR / m)]m – 1.

### Rate example, I

• You went to a bank to borrow \$10,000. You were told that the rate is quoted as “8% compounded semiannually.” What is the amount of debt after a year?

• FV = PV  (1 + i)N = \$10,000  (1 + 4%)2 = \$10,816.

• EAR = [1 + (APR / m)]m – 1= [1 + (8% / 2)]2 – 1 = 8.16%.

### Rate example, II

• What is the APR if the monthly rate is 1%?

• APR = 1%  12 = 12%.

• What is the monthly (period) rate if the APR is 6% with monthly compounding?

• Period (monthly) rate = 6% / 12 = 0.5%.

### Continuously compounding

• FV = PV × eAPR×the number of years , where e has the value of 2.718.

• Suppose that you invest \$1,000 at a continuously compounded rate of 10% for a year.

• FV = PV × eAPR×the number of years = \$1,000 × e10%×1 = \$1,105.20. So, EAR = 10.52%.

### APR vs. EAR in real life

• By Trust-in-saving law, banks need to disclose EAR ( or called annual percentage yield (APY), or effective annual yield (EAY)). So you get the correct rate when you save.

• By Trust-in-lending law, banks need to disclose APR, the stated (quoted) rate. So you get a seemingly low rate when you borrow.

### Extra

• In residential mortgage markets, “APR” is the cost of credit that includes the quoted rate and transactions costs.

• This APR is higher than the quoted rate.

• If it is 0.75%-1% higher than the quoted rate, the financial charges and fees are most likely too high.

• Example: a quote from quickloans.com: rate 3.625% (3.8% APR)

### Pure discount loans

• Pure discount loans: the borrower receives money today and repays a single lump sum at some time in the future.

• Treasury bills: U.S. government borrows money and promises to repay a fixed amount at some time less than one year. Suppose that the maturity is 12 months. The face value is \$10,000. The market discount rate is 7%. How much do you need to pay for the T-bill?

• PV = FV / (1 + i)N = \$10,000 / (1 + 7%)1 = \$9,345.79.

### Amortized loans

• Amortized loans: the loans that are paid off by making regular principal reductions.

• Payment per period = interest + a portion of principal.

• The most common type of amortized loans require borrowers make a single, fixed payment every period, i.e., annuity.

• 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 \$5,500. The interest rate on the loan is 6% per year with monthly compounding (.5% per month) for a 30-year fixed rate loan. You are able to buy the house at \$154,500. What is the monthly payment? Suppose that you have an annual salary of \$50,000. What is the ratio of the mortgage payment to your monthly income?

• Down payment = \$20,000 – \$5,500 = \$14,500.

• Loan = \$154,500 – \$14,500 = \$140,000.

• Calculator: 140000 PV; 0.5 I/Y; 360 N; CPT PMT. The answer is: PMT = -839.3707.

• PMT/income = \$839.3707 / (\$50,000 / 12) = 20.14%.

• Banks usually do not want to see this ratio to be higher than 25%.

### Interest-only loans

• Interest-only loans: borrower pays interest each period and repay the entire original principal at some time in the future.

• Example: bonds.

• This serves as a launch point for next topic: Chapters 8 & 9: How to value bonds and stocks.

### Review: let us work on this one

• Q11, P. 125: Conoly Co. Has identified an investment project with the following cash flows. If the discount rate is 10%, what is the PV?

• Year 1: \$960. Year 2: \$840. Year 3: \$935. Year 4: \$1,350.

### Review: let us work on this one

• Concept #3, p. 123. Suppose that two athletes sign 10-year contracts for \$80 million. In one case, we are told that the \$80 million will be paid in 10 equal installments. In the other case, we are told that the \$80 million will be paid in 10 installments, but the installments will increase by 5% per year. Who got the better deal? Why?
