How expensive is grad school?How long will it take?How much more will I make with a grad degree?What are the opportunity costs of wages while in gradschool?
Repair or Replace CarHow expensive is new car?How much are my expected repair bills going to bewith the old car?How long before the old car is inoperable?

EXAMPLE: COLLEGE CASH FLOWSEXAMPLE: COLLEGE CASH FLOWSAverage costs to attend a 4 year public university in the U.S. have risen fromabout 27,161 in 1996 to about 39,529 in 2016. As of 2018, the average annual earnings for a high school graduate were
48,000. The average starting annual earnings for a college graduate with abusiness degree were 62,000. For simplicity, let's ignore taxes and justassume these are all after-tax cash �ows. Assume that you complete the degree in 4 years. You work for 45 yearsafter attaining your degree and college salary grows at 3% annually. All cash�ows occur at the end of the period (e.g. no out�ows at t=0).
We will come back to this and use investment criteria to make decision.

TOOLSTOOLS1. Net Present Value (NPV)2. Payback Period3. Internal Rate of Return
SAMPLE PROJECTSAMPLE PROJECTYou are looking at a new project and have estimated thefollowing cash �ows, net income and book value data:
Year Cash Flow
0 -165,000
1 63,120
2 70,800
3 91,080Required return = 12%
This project will be the example for all problem exhibits in
this chapter.
NET PRESENT VALUENET PRESENT VALUE
OVERVIEWOVERVIEWHow much value is created from undertaking an investment?
1. Estimate the expected future cash �ows.2. Estimate the required return for projects of this risk
level.3. Find the present value of the cash �ows and subtract the
initial investment to arrive at the Net Present Value.
CALCULATIONCALCULATION
Initial cost is often and is an out�ow.

DECISION RULEDECISION RULEIf NPV is positive, accept the project
What does a positive NPV mean?Project is expected to add value to the �rmWill increase the wealth of the owners
NPV is a direct measure of how well this project willmeet the goal of increasing shareholder wealth.

DECISION RULEDECISION RULE
Accept Project if NPV > 0
PROS AND CONSPROS AND CONSPros
Meets all desirable criteriaConsiders all Cash FlowsConsiders Time Value of MoneyAdjusts for riskCan rank mutually exclusive projects
Directly related to �rm valueDominant method; always prevails
Consrelies heavily on correct discount rate
PAYBACK PERIODPAYBACK PERIOD
OVERVIEWOVERVIEWHow long does it take to recover the initial cost of a project?
Computation1. Estimate cash �ows2. Subtract the future cash �ows from the initial cost until
initial investment is recoveredA "break-even" type measure

Payback = 2 + 31080/91080 2.34 years
Payback = 2 + =2.34 years
Do we accept or reject the project?

DECISION RULEDECISION RULE
Accept if the payback period is less than some preset limit
PROS AND CONSPROS AND CONSAdvantages
Easy to understandAdjusts for uncertainty oflater cash �owsBiased towards liquidityGood for small projects(< 10000)
DisadvantagesIgnores the time value ofmoneyRequires an arbitrarycuto� pointIgnores cash �ows beyondthe cuto� dateBiased against long-termprojects, such as researchand development
ASKS THE WRONG QUESTION!

INTERNAL RATE OF RETURN (IRR)INTERNAL RATE OF RETURN (IRR)
OVERVIEWOVERVIEWMost important alternative to NPVWidely used in practiceIntuitively appealingBased entirely on the estimated cash �owsIndependent of interest rates
DEFINITIONDEFINITIONIRR = discount rate that makes the NPV = 0
Enter NPV = 0, solve for IRR:
NPV = ∑t=0

OVERVIEWOVERVIEWNPV and IRR will generally give the same decisionExceptions
Non-conventional cash �owsCash �ow sign changes more than once
Mutually exclusive projectsInitial investments are substantially di�erentTiming of cash �ows is substantially di�erentWill not reliably rank projects
NON-CONVENTIONAL CASH FLOWSNON-CONVENTIONAL CASH FLOWSCash �ows change sign more than once
Produces more than one IRRWhich one do you use to make your decision?
EXAMPLEEXAMPLESuppose an investment will cost 90,000 initially and will
generate the following cash �ows: Year 1: 132,000Year 2: 100,000Year 3: -150,000
The required return is 15%.
Should we accept or reject the project?

IndependentThe cash �ows of one project are una�ected by theacceptance of the other.
Mutually ExclusiveThe acceptance of one project precludes acceptingthe other.

PRACTICEPRACTICE
EXAMPLE 1EXAMPLE 1Consider an investment that costs 100,000 and has a
cash in�ow of 25,000 every year for 5 years. The requiredreturn is 9% and required payback is 4 years.
What is the payback period?What is the NPV?What is the IRR?Should we accept the project?What decision rule should be the primary decisionmethod?When is the IRR rule unreliable?
