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

MethodWhat it MeasuresProsCons
Payback PeriodTime to recover investmentSimple, quick, focuses on liquidityIgnores cash after payback, ignores time value
Net Present Value (NPV)Total value added in today’s termsConsiders time value, risk, and all cash flowsRequires accurate discount rate, more complex
Internal Rate of Return (IRR)Rate of return that makes NPV zeroEasy to compare with required rate of returnCan 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{CFt}{(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! 🍀
