To calculate the Internal Rate of Return (IRR) of Project A, we need to find the discount rate that makes the Net Present Value (NPV) of the project equal to zero. The formula for NPV is given as:

$\text{NPV} = \sum_{t=0}^{n} \frac{C_t}{(1 + r)^t}$ Where:

• $C_t$ is the cash flow at time $t$,
• $r$ is the IRR,
• $t$ is the year.

For Project A, the cash flows are:

• Year 0: -20.00
• Year 1: 9.00
• Year 2: 8.00
• Year 3: 6.00
• Year 4: 4.00

IRR Calculation:

We solve for $r$ in the equation where the NPV is set to zero:

$0 = \frac{-20.00}{(1 + r)^0} + \frac{9.00}{(1 + r)^1} + \frac{8.00}{(1 + r)^2} + \frac{6.00}{(1 + r)^3} + \frac{4.00}{(1 + r)^4}$

Since this is a non-linear equation, it's typically solved using numerical methods such as trial and error or using a financial calculator or Excel.

Let me calculate the IRR for you.The Internal Rate of Return (IRR) for Project A is approximately 15.30%.

Here are 5 related questions to expand on this topic:

1. How does the IRR compare to the project's cost of capital?
2. How would you calculate the IRR for Project B?
3. What are the advantages and limitations of using IRR as a decision-making tool?
4. How is IRR different from the Net Present Value (NPV) method?
5. Can two mutually exclusive projects have the same IRR but different NPVs?

Tip: If the IRR exceeds the cost of capital, the project is generally considered a good investment.
