Present and Future Value
Present Value: value of a future payment today Future Value: value that an investment will
grow to in the future We find these by discounting or compounding
at the discount rateAlso know as the hurdle rate or the opportunity
cost of capital or the interest rate

One Period Discounting
PV = Future Value / (1+ Discount Rate)V0 = C1 / (1+r)
Alternatively PV = Future Value * Discount Factor
V0 = C1 * (1/ (1+r))
Discount factor is 1/ (1+r)
7
NPV NPV = PV of all expected cash flows
Represents the value generated by the projectTo compute we need: expected cash flows &
the discount rate Positive NPV investments generate value Negative NPV investments destroy value
8
Net Present Value (NPV)
NPV = PV (Costs) + PV (Benefit)Costs: are negative cash flowsBenefits: are positive cash flows
One period exampleNPV = C0 + C1 / (1+r) For Investments C0 will be negative, and C1 will be
positiveFor Loans C0 will be positive, and C1 will be negative
9
Net Present Value Example
Suppose you can buy an investment that promises to pay $10,000 in one year for $9,500. Should you invest?
10
Net Present Value
Since we cannot compare cash flow we need to calculate the NPV of the investmentIf the discount rate is 5%, then NPV is?
At what price are we indifferent?

Coffee Shop Example
If you build a coffee shop on campus, you can sell it to Starbucks in one year for $300,000
Costs of building a coffee shop is $275,000
Should you build the coffee shop?
14
Step 2: Find the Discount Rate
Assume that the Starbucks offer is guaranteed US T-Bills are risk-free and currently pay 7%
interestThis is known as rf
Thus, the appropriate discount rate is 7%Why?
16
If we are unsure about future?
What is the appropriate discount rate if we are unsure about the Starbucks offerrd = rf
rd > rf
rd < rf
17
The Discount Rate
Should take account of two things:1. Time value of money
2. Riskiness of cash flow The appropriate discount rate is the
opportunity cost of capital This is the return that is offer on comparable
investments opportunities
18
Risky Coffee Shop
Assume that the risk of the coffee shop is equivalent to an investment in the stock market which is currently paying 12%
Should we still build the coffee shop?
20
Future Cash Flows Since future cash flows are not certain, we
need to form an expectation (best guess)Need to identify the factors that affect cash flows
(ex. Weather, Business Cycle, etc).Determine the various scenarios for this factor (ex.
rainy or sunny; boom or recession)Estimate cash flows under the various scenarios
(sensitivity analysis)Assign probabilities to each scenario
21
Expectation Calculation The expected value is the weighted average of X’s
possible values, where the probability of any outcome is p
E(X) = p1X1 + p2X2 + …. psXs E(X) – Expected Value of X Xi Outcome of X in state i pi – Probability of state i s – Number of possible states
Note that = p1 + p2 +….+ ps = 1
22
Risky Coffee Shop 2
Now the Starbucks offer depends on the state of the economy
Recession Normal BoomValue 300,000 400,000 700,000
Probability 0.25 0.5 0.25
23
Calculations Discount Rate = 12% Expected Future Cash Flow =
NPV =
Do we still build the coffee shop?
24
Valuing a Project Summary
Step 1: Forecast cash flows Step 2: Draw out the cash flows Step 3: Determine the opportunity cost of
capital Step 4: Discount future cash flows Step 5: Apply the NPV rule
25
Reminder
Important to set up problem correctly Keep track of
• Magnitude and timing of the cash flows
• TIMELINES You cannot compare cash flows @ t=3 and @
t=2 if they are not in present value terms!!
26
General Formula
PV0 = FVN/(1 + r)N OR FVN = PVo*(1 + r)N
Given any three, you can solve for the fourthPresent value (PV)Future value (FV)Time period Discount rate

Four Related Questions
1. How much must you deposit today to have $1 million in 25 years? (r=12%)
2. If a $58,823.31 investment yields $1 million in 25 years, what is the rate of interest?
3. How many years will it take $58,823.31 to grow to $1 million if r=12%?
4. What will $58,823.31 grow to after 25 years if r=12%?
28
FV Example Suppose a stock is currently worth $10, and is
expected to grow at 40% per year for the next five years.
What is the stock worth in five years?
0 1 2 3 4 5
$10 27.4419.614 38.42

PV Example
How much would an investor have to set aside today in order to have $20,000 five years from now if the current rate is 15%?
0 1 2 3 4 5
$20,000PV

Simple vs. Compound Interest
Simple Interest: Interest accumulates only on the principal
Compound Interest: Interest accumulated on the principal as well as the interest already earned
What will $100 grow to after 5 periods at 35%?• Simple interest
FV2 = (PV0 * (r) + PV0 *(r)) + PV0 = PV0 (1 + 2r) =• Compounded interest
FV2 = PV0 (1+r) (1+r)= PV0 (1+r)2 =
31
Compounding Periods
We have been assuming that compounding and discounting occurs annually, this does not need to be the case
32
Non-Annual Compounding Cash flows are usually compounded over
periods shorter than a year The relationship between PV & FV when
interest is not compounded annuallyFVN = PV * ( 1+ r / M) M*N
PV = FVN / ( 1+ r / M) M*N
M is number of compounding periods per year N is the number of years
33
Compounding Examples
What is the FV of $500 in 5 years, if the discount rate is 12%, compounded monthly?
What is the PV of $500 received in 5 years, if the discount rate is 12% compounded monthly?
34
Interest Rates
The 12% is the Stated Annual Interest Rate (also known as the Annual Percentage Rate)This is the rate that people generally talk about
Ex. Car Loans, Mortgages, Credit Cards However, this is not the rate people earn or pay The Effective Annual Rate is what people actually
earn or pay over the yearThe more frequent the compounding the higher the
Effective Annual Rate
35
Compounding Example 2
If you invest $50 for 3 years at 12% compounded semi-annually, your investment will grow to:
Compounding Example 2: Alt. If you invest $50 for 3 years at 12% compounded
semi-annually, your investment will grow to: Calculate the EAR: EAR = (1 + R/m)m – 1
So, investing at compounded annually is the same as investing at 12% compounded semi-annually

Present Value Of a Cash Flow Stream
Discount each cash flow back to the present using the appropriate discount rate and then sum the present values.

If the issuer offers this investment for $1,500, should you purchase it?

Alternative: Use a Financial Calculator Texas Instruments BA-II Plus, basic
N = number of periods I/Y = periodic interest rate
P/Y must equal 1 for the I/Y to be the periodic rate Interest is entered as a percent, not a decimal
PV = present value PMT = payments received periodically FV = future value Remember to clear the registers (CLR TVM) after each
problem Other calculators are similar in format

Annuity Example 2 You agree to lease a car for 4 years at $300 per month.
You are not required to pay any money up front or at the end of your agreement. If your opportunity cost of capital is 0.5% per month, what is the cost of the lease? Work through on your financial calculators

What Is a Firm Worth?
Conceptually, a firm should be worth the present value of the firm’s cash flows.
The tricky part is determining the size, timing, and risk of those cash flows.
