Chapter 5. The Moment of Decision: Capital Budgeting (NPV vs. IRR)

Should a company build a new semiconductor factory that costs 10billion?Shouldamoviestudiogreenlighta10 billion? Should a movie studio greenlight a 200 million blockbuster? These are the high-stakes decisions of Capital Budgeting.

Today, we will learn how to transition from “hope” to “logic” by using mathematical tools to determine if a project will actually create value for shareholders.


1. NPV: The Gold Standard

Net Present Value (NPV) is the cornerstone of corporate finance. it is calculated as: ==NPV = (Present Value of Future Cash Inflows) - (Initial Investment)==

  • NPV > 0: The project creates value. ==Accept!==
  • NPV < 0: The project destroys value. ==Reject!==

Why NPV is the Best

FeatureBenefitWhy it matters
Time Value of MoneyReflectedConsiders the cost of capital correctly
Cash Flow FocusReflectedAccounting profits are ignored for 'real' cash
AdditivityPossibleTotal NPV = NPV(A) + NPV(B)

2. IRR: The Rate of Intuition

Internal Rate of Return (IRR) is the discount rate that makes the NPV of a project exactly zero. It represents the “break-even” rate of a project.

1
Cost of Capital

Know your required rate of return (k)

2
Calculate IRR

Solve for the rate where PV(Inflow) = PV(Outflow)

3
Compare

Is IRR > k? (Return > Cost)

4
Decision

If Return is higher than Cost, Accept!

==The Clash of Titans==: Most of the time, NPV and IRR agree. However, when projects have different scales or timing, NPV is always the superior choice because it measures the absolute wealth created, not just a percentage.


3. Alternative Tools: Payback Period & PI

Sometimes, managers use simpler tools for a quick check.

Supplementary Decision Tools

MethodCore QuestionPros/Cons
Payback PeriodHow fast do I get my money back?Simple but ignores TVM and late cash flows
Profitability Index (PI)How much value per $1 invested?Great for selecting under budget constraints

4. Conclusion: Wealth Creation in Action

Capital budgeting is not just about crunching numbers. It’s about ==“Strategic Resource Allocation.”== A company that consistently accepts (+) NPV projects will see its stock price soar as it builds a future of sustainable cash flows.
