1. What capital budgeting is
2. How to calculate and interpret a project’s: Payback Period
Discounted Payback Period
Net Present Value (NPV)
Internal Rate of Return (IRR)

What is capital budgeting?
Capital budgeting is the process of planning
expenditure on assets or projects that can have a
long-term impact on an institution.
Examples of capital projects
Adopting a new enterprise-wide software system
Launching a new advertising campaign
Replacing factory equipment
Expanding sales into a new market
Building a road
Why is capital budgeting
important?
Helps firm make smart decisions
Capital projects large and expensive- not easy to
change course
Allows management team to give input and be on
same page
Capital budgeting techniques
include:
Payback Period
Discounted Payback Period
Net Present Value (NPV)
Internal Rate of Return (IRR)
Profitability Index (PI)
Payback Period- The Concept
What is it?
The payback period for a project is the expected
time it will take to recover the original investment.
The decision rule:
Accept project if its payback period is less than the
maximum allowed.
Payback Period- An Example
A project requires a $100,000,000 investment and
is expected to generate the following cash flows in
the years after the investment is made
What is the payback period?
Year Cashflow ($)
1 20,000,000
2 40,000,000
3 60,000,000
4 30,000,000
5 10,000,000
Payback Period- Example cont’d
Workings:
The payback period is somewhere between the end
of year 2 and the end of year 3
Year Cashflow ($) Cumulative
Cashflow
1 20,000,000 20,000,000
2 40,000,000 60,000,000
3 60,000,000 120,000,000
4 30,000,000 150,000,000
5 10,000,000 160,000,000
Payback Period- Example cont’d
Use linear interpolation to find the exact figure for payback
period
By using linear interpolation, the assumption is that cashflows
occur evenly throughout the year
We get:
X – 2 = 100,000,000 – 60,000,000
3 – 2 120,000,000 – 60,000,000
X = 2.67 years (This is the payback period)
Payback Period- Example cont’d
If projects with a payback period of up to 4 years
are acceptable, should the firm accept this project?
Answer:
Yes, since the payback period is less than 4 years.
Payback Period- The Pros
It is easy to calculate
It is easy to explain
It uses cashflows (not accounting profits)
It gives a measure of the liquidity of a project
Payback Period- The Cons
How to decide maximum allowable payback period?
Very subjective
Time value of money not taken into consideration
Project’s riskiness not accounted for properly
Cashflows beyond the payback period are ignored
No connection to maximizing the firm’s value
Discounted Payback Period-
The Concept
What is it?
The discounted payback period for a project is the
expected time it will take for the discounted cash
flows to recover the original investment.
The decision rule:
Accept project if its discounted payback period is
less than the maximum allowed.
Discounted Payback Period-
Example
A project requires a $100,000,000 investment and
is expected to generate the following cash flows in
the years after the investment is made
What is the discounted payback period based on
a discount rate of 10%?
Year Cashflow ($)
1 20,000,000
2 40,000,000
3 60,000,000
4 30,000,000
5 10,000,000
Discounted Payback Period-
Example cont’d
Workings:
The discounted payback period is somewhere
between the end of year 3 and the end of year 4
Year Cashflow ($) PV of
Cashflow ($)
Cumulative PV of
cashflow ($)
1 20,000,000 18,181,818 18,181,818
2 40,000,000 33,057,851 51,239,669
3 60,000,000 45,078,888 96,318,557
4 30,000,000 20,490,404 116,808,961
5 10,000,000 6,209,213 123,018,174
Discounted Payback Period-
Example cont’d
Use linear interpolation to find the exact figure for the
discounted payback period
By using linear interpolation, the assumption is that the
discounted cashflows occur evenly throughout the year
We get:
Y – 3 = 100,000,000 – 96,318,557
4 – 3 116,808,961 – 96,318,557
Y = 3.18 years (This is the discounted payback period)
Discounted Payback Period-
Example cont’d
If projects with a discounted payback period of up to
5 years are acceptable, should the firm accept this
project?
Answer:
Yes, since the discounted payback period is less
than 5 years.
Discounted Payback Period-
The Pros & Cons
The pros and cons are almost the same as with the
basic payback period technique
Only improvement is that cashflows are discounted
However, since cashflows beyond discounted
payback period are ignored, TVM still not handled
adequately
Net Present Value (NPV)-
The Concept
What is it?
The net present value of a project is the sum of the
present values of its expected cash flows.
The decision rule:
Accept project if its NPV > 0.
NPV- An Example
A project requires a $100,000,000 investment and
is expected to generate the following cash flows in
the years after the investment is made
What is the NPV for this project if the discount
rate is 10%?
Year Cashflow ($)
1 20,000,000
2 40,000,000
3 60,000,000
4 30,000,000
5 10,000,000
NPV- Example cont’d
Workings:
The NPV of the project is $23,018,174
Year Cashflow ($) PV of Cashflow ($)
0 -100,000,000 -100,000,000
1 20,000,000 18,181,818
2 40,000,000 33,057,851
3 60,000,000 45,078,888
4 30,000,000 20,490,404
5 10,000,000 6,209,213
Total 23,018,174
NPV- Example cont’d
Should this project be accepted?
Answer:
Yes, since NPV > 0.
NPV Exercise
1. Calculate the NPV of the same project we just
looked at, this time using a discount rate of 20%.
2. Would you still accept this project?
3. Why or why not?
4. Under what circumstances would a discount rate of
20% be more appropriate than a discount rate of
10% for this project?
NPV Exercise Results
1. NPV = -2,346,965
2. We would reject this project
3. Reject since NPV <0
Year Cashflow ($) PV of Cashflow ($)
0 -100,000,000 -100,000,000
1 20,000,000 16,666,666
2 40,000,000 27,777,777
3 60,000,000 34,722,222
4 30,000,000 14,467,592
5 10,000,000 4,018,775
Total -2,346,965
NPV-
The Discount Rate Used:
Has a significant impact on NPV result
Should be the required return on the project
Should be in line with the project’s risk Are the estimated cash flows almost a certainty or very
uncertain?
Will the fixed costs (operating leverage) be high ?
Will the amount of debt used (financial leverage) be high?
NPV-
The Discount Rate Selection Cont’d
Projects with higher risk should use higher discount
rate
Many firms use WACC and adjust up or down to
account for project’s riskiness
Alternatively, project’s beta can be calculated and
used to determine project’s required return via
CAPM
NPV- The Pros
Relatively easy to calculate
Uses cash flows (not accounting profits)
Time value of money handled properly
Project’s riskiness considered appropriately
Shows expected impact on company’s value
Internal Rate of Return (IRR)-
The Concept
A project’s IRR is the discount rate that causes the
NPV of all project cash flows to equal zero.
Set NPV to zero, and solve for r.
IRR- Decision Rule
A typical project has outflows at the beginning
For a typical project:
If IRR > Project’s required return, accept project
The required return is used as a hurdle rate
The required return should be in keeping with the
riskiness of the project
IRR- An Example
A project requires a $100,000,000 investment and
is expected to generate the following cash flows in
the years after the investment is made
What is the IRR of this project?
Year Cashflow ($)
1 20,000,000
2 40,000,000
3 60,000,000
4 30,000,000
5 10,000,000
IRR- Example cont’d
To find IRR we would use:
Trial and error
A financial calculator, or
A spreadsheet
Result is IRR = 18.9%
IRR- Example cont’d
If required return = 10% accept project
(Since IRR > 10%)
If required return = 20%, reject project
(Since IRR < 20%)
Notice that IRR and NPV provide consistent accept/
reject decision here
IRR- Things to be mindful of
Projects with inflows first
Multiple IRRs
No real solution
The reinvestment rate assumption
Ranking projects
IRR- Projects with inflows first
The decision rule changes
Accept if IRR < Project’s required return
Reason: Having Inflows first is equivalent to
borrowing
Lower rate preferred when borrowing
IRR- Multiple IRRs
When cash flows alternate between negative an
positive values
Project can have more than one IRR
Incorrect conclusions can be made
Use NPV to make conclusion
IRR- No Real Solution
Sometimes, no interest rate exists that can make the
PV of cash flows equal zero.
The solution involves imaginary numbers
In these cases, calculator/ spreadsheet shows an
error message
IRR- The Reinvestment Rate
Assumption
Assumption is that interim cash inflows can be
invested at the IRR
If IRR is high, that assumption may not be met
Actual return will be lower than what IRR suggests
Exercise- IRR and Ranking Projects
1. Given the following, which project should be
ranked higher? Why?
2. Why might “Project Renovate” have the higher IRR
but the lower NPV?
Project Name NPV at 15% IRR
Renovate 25,000,000 42%
Totally New 53,000,000 18%
Exercise- Answers
Project “Totally New” should be ranked higher
Why? It has higher NPV
NPV shows value to shareholders
Exercise- Answers cont’d
Project “Renovate” may have higher IRR but lower
NPV due to:
1. Difference in project scale
2. Difference in timing of cash flows
IRR- The Scale Problem
When projects are of different size take care when
using IRR
Determine IRR of incremental project to rank them
Necessary when dealing with mutually exclusive
projects
Unnecessary otherwise (Accept both)
IRR- The Timing Problem
When the cash flow timing of two projects is
significantly different, take care when using IRR
Determine IRR of incremental project to rank them
Necessary when dealing with mutually exclusive
projects
Unnecessary otherwise (Accept both)
IRR- Pros
Results intuitive
Uses cash flows
Takes account of time value of money
Takes account of risk
Connected to impact on firm’s value
IRR- The Cons
Possibility of multiple IRRs
Possibility of no real solution
The reinvestment rate assumption
The scale problem
The timing problem
Profitability Index (PI)
What is it?
Profitability = _PV of future cash flows__
Index Initial Investment
It shows the value created per dollar invested
PI- Decision Rule
If PI > 1, accept project
PI- An Example
A project requires a $100,000,000 investment and
is expected to generate the following cash flows in
the years after the investment is made
What is the profitability index of this project based
on a discount rate of 10%?
Year Cashflow ($)
1 20,000,000
2 40,000,000
3 60,000,000
4 30,000,000
5 10,000,000
PI- Example cont’d
Workings:
PI = 123,018,174_ = 1.23
100,000,000
Year Cashflow ($) PV of
Cashflow ($)
1 20,000,000 18,181,818
2 40,000,000 33,057,851
3 60,000,000 45,078,888
4 30,000,000 20,490,404
5 10,000,000 6,209,213
Total 123,018,174
PI- Example cont’d
Should this project be accepted?
Answer:
Yes, since PI > 1.
PI- The Scale Problem
PI suffers same scale problem as IRR
Thus, care required when handling mutually
exclusive projects
Determine PI of incremental project to make
decision
Capital Rationing
Capital rationing is the act of putting a limit on
the amount of money that can be spent on new
projects.
Reasons for capital rationing
include:
Inability or unwillingness to issue more debt or
equity
Limited qualified personnel to implement all projects
Discouraging cash flow assumptions that are over-
optimistic
Choosing projects under capital
rationing
Objective: Choose combination of projects that
gives the highest NPV
Profitability Index can be useful in this regard
But take care when using PI due to scale problem
Capital Rationing Example
Which of the following independent projects should
be embarked upon if the capital constraint this year
is $300,000,000?
Project Investment NPV PI
A 70,000,000 59,200,000 1.8
B 80,000,000 52,000,000 1.6
C 100,000,000 59,600,000 1.6
D 150,000,000 38,400,000 1.3
E 200,000,000 71,000,000 1.4
Capital Rationing Example cont’d
Answer:
Projects A, B & C
No other combination that adheres to the capital
constraint gives a higher combined NPV
