Discounted Cash Flow Valuation
FV = C0×(1 + r)T
Where C0 is cash flow today (time zero) and
r is the appropriate interest rate.
Ex: Suppose you invest $500 in a bank 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
PV=Future Value of t Period/(1 + r)T
Ex: You just bought a new computer for $3,000. The payment terms are 2 years same as cash. If you can earn 8% on your money, how much money should you set aside today in order to make the payment when due in two years?
PV=3,000/(1 + 0.08)2 = $2,572
-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 constant stream of cash flows with a fixed maturity.
The formula for the present value of an annuity is:
Ex1: You are purchasing a car. You are scheduled to make 3 annual installments of $4,000 per year. Given a rate of interest of 10%, what is the price you are paying for the car (i.e. what is the PV)?
Ex2: You plan to save $4,000 every year for 20 years and then retire. Given a 10% rate of interest, what will be the FV of your retirement account?
A constant stream of cash flows that lasts forever.
The formula for the present value of a perpetuity is:
Ex1: An investment offers a perpetual cash flow of $500 every year. The return you require on such an investment is 8 percent. What is the value of this investment?
Ex2: Suppose the Fellini Co wants to sell preferred stock at $100 per share. A very similar issue of preferred stock already outstanding has a price of $40 per share and offers a dividend of $1 every quarter. What dividend will Fellini have to offer if the preferred stock is going to sell?
The issue that is already out has a present value of $40 and a cash flow of $1 every quarter forever.
Where m is the number of periods per year
EAR= (1+ 0.0525/365)365=5.39%
EAR= (1+ 0.053/2)2-1=5.37%
Which account should you choose and why?
Let’s verify the choice. Suppose you invest $100 in each account. How much will you have in each account in one year?
Daily rate= 0.0525/365=0.00014383562
You have more money in the first account.
Annual percentage rate (APR) is the interest rate charged per period multiplied by the number of periods per year. The quoted rate is the same as an APR.
For example. An APR of 12 percent on a loan calling for monthly payments is really 1 percent per month. The EAR on such a loan is thus:
Ex: 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?
If you have effective rate, how can you compute the APR?
Rearrange the EAR equation you get:
Borrower receives money today and repays a single lump sum at some time in the future. Treasury bills are a common example of pure discount loans.
Borrower pays interest only each period and the entire principal at maturity. Corporate bonds are a common example of interest-only loans.
Consider a 5-year, interest only loan with a 7% interest rate. The principal amount is $10,000. Interest is paid annually.
What would the stream of cash flows be?
Years 1-4: Interest payments of 0.07(10,000)=700
Year 5: Interest + Principal=10,700
Borrowers repay part or all of principal over the life of the loan. Two methods are (1) fixed amount of principal to be repaid each period, which results in uneven payments, and (2) fixed payments, which results in uneven principal reduction. Traditional auto and mortgage loans are example of the second type of amortized loans.
For example. suppose a business takes out a $5,000, five-year loan at 9 percent. The loan agreement calls for the borrower to pay the interest on the loan balance each year and to reduce the loan balance each year by $1,000. Since the loan amount declines by $I,000 each year, it is fully paid in five years.
Probably the most common way of amortizing a loan is to have the borrower make a single fixed payment every period.
In the first year. the interest is $450. Since the total payment is $1,285.46. the principal paid in the first year must be:
Principal paid =$1,285.46 - 450 = $835.46
The ending loan balance is thus:
Ending balance =$5,000 - 835.46 = $4,164.54
End of Chapter payment is $1,285.46. the principal paid in the first year must be:5
