Capital Budgeting Decision Framework

A structured approach to evaluating investment projects using NPV, IRR, payback, and profitability index.

What You'll Learn

  • βœ“Identify relevant cash flows
  • βœ“Apply multiple evaluation metrics
  • βœ“Make consistent accept/reject decisions

1. Identify Incremental Cash Flows

Only include cash flows that change because of the project. Ignore sunk costs. Include opportunity costs and side effects.

Key Points

  • β€’Sunk costs are irrelevant
  • β€’Opportunity costs are relevant
  • β€’Include cannibalization effects on existing products

2. Apply NPV as Primary Rule

Discount all incremental cash flows at the appropriate rate. Positive NPV creates shareholder value.

Key Points

  • β€’NPV handles scale and timing correctly
  • β€’Use WACC for average-risk projects
  • β€’Adjust for project-specific risk when needed

3. Check IRR and Payback

Use IRR for intuition and communication. Use payback for liquidity screening. Neither replaces NPV.

Key Points

  • β€’IRR can mislead with non-conventional cash flows
  • β€’Payback ignores time value and post-cutoff flows
  • β€’All three metrics should align for a clear decision

4. Rank Under Constraints

When capital is limited, use profitability index to maximize value per dollar invested.

Key Points

  • β€’PI = PV of cash flows / initial investment
  • β€’Rank by PI, select top projects within budget
  • β€’Check if the combination is feasible

Key Takeaways

  • β˜…Working capital investment at start must be recovered at end
  • β˜…Tax depreciation creates a cash flow (tax shield)
  • β˜…Terminal value in project analysis differs from DCF terminal value

Practice Questions

1. A factory was purchased last year for $1M to evaluate this project. Is the $1M relevant?
No. It is a sunk cost and should not affect the project decision.
2. Project NPV = $50K, IRR = 8%, hurdle = 10%. Accept or reject?
Reject. Although NPV seems positive, recheckβ€”IRR < hurdle usually means NPV should be negative. There may be a calculation error.
