the need for investment appraisal
10.3 Investment Appraisal – Concept of Investment Appraisal
What is Investment Appraisal?
Investment appraisal is like being a detective who decides which treasure chest to open. It helps a business figure out whether a new project (e.g., opening a store, launching a product, buying equipment) will bring enough money back to justify the cost. 📦🔍
Why do we need Investment Appraisal?
Imagine you have a limited amount of money, like a pocket‑knife of cash. You want to spend it on the best possible adventure. Investment appraisal gives you a road map to compare different adventures (projects) and choose the one that gives you the most value for money.
- 🔒 Risk Management – Shows how risky a project is.
- ⏰ Time Value of Money – Money today is worth more than money later.
- 💰 Opportunity Cost – Highlights what you miss out on if you choose one project over another.
- 📊 Decision Support – Provides clear numbers for managers and investors.
Key Concepts
- Cash Flows – Inflows and outflows over time.
- Discount Rate – The rate used to convert future cash flows into today’s value.
- Net Present Value (NPV) – The sum of discounted cash flows minus the initial investment.
- Internal Rate of Return (IRR) – The discount rate that makes NPV zero.
- Payback Period – How long it takes to recover the initial investment.
Common Appraisal Methods
| Method | What it Measures | Pros | Cons |
|---|---|---|---|
| Payback Period | Time to recover investment | Simple, quick, focuses on liquidity | Ignores cash after payback, ignores time value |
| Net Present Value (NPV) | Total value added in today’s terms | Considers time value, risk, and all cash flows | Requires accurate discount rate, more complex |
| Internal Rate of Return (IRR) | Rate of return that makes NPV zero | Easy to compare with required rate of return | Can give multiple values, sensitive to cash flow patterns |
Example: A New Store
Suppose a shop wants to open a new outlet. The initial cost is £50,000. Expected cash inflows over 5 years are £12,000, £15,000, £18,000, £20,000, and £22,000. The discount rate is 8%.
NPV calculation:
$NPV = \sum_{t=1}^{5} \frac{CF_t}{(1+0.08)^t} - 50{,}000$
Plugging in the numbers gives an NPV of approximately £3,200, meaning the project adds value and should be accepted. 🎉
Exam Tips
Remember:
- Always state the discount rate and the period.
- Show all steps in NPV and IRR calculations.
- Explain the significance of a positive vs. negative NPV.
- Use diagrams or tables to summarise cash flows.
- Check your units – cash flows are in £, rates in %.
Good luck, and keep your calculations neat! 🍀
