Calculate the IRR of the following project:

Year Cash Flow
0 -$30,000
1 $40,000

To calculate the Internal Rate of Return (IRR) of a project, you need to find the discount rate at which the net present value (NPV) of the project's cash flows is equal to zero. The IRR is the rate at which the project breaks even.

To calculate the IRR, follow these steps:

Step 1: Identify the cash flows and their corresponding time periods. In this case, we have the following cash flows:
Year 0: -$30,000
Year 1: $40,000

Step 2: Set up the formula for calculating the NPV. The general formula for NPV is:
NPV = CF0 / (1 + r)^0 + CF1 / (1 + r)^1 + ...

Where CF0 is the cash flow in Year 0, CF1 is the cash flow in Year 1, r is the discount rate, and ^ represents exponentiation.

In this case, the formula becomes:
0 = -30,000 / (1 + r)^0 + 40,000 / (1 + r)^1

Step 3: Solve for r. Rearrange the equation to solve for the discount rate (r) that makes the NPV equal to zero. This can be done using iterative techniques or financial calculators. Alternatively, you can use software like Microsoft Excel, which has a built-in function for calculating IRR.

By using Excel, you can enter the cash flows into cells A2 and B2, with "-30000" in A2 and "40000" in B2. Then, use the IRR function to calculate the IRR by inputting "=IRR(B2,A2)" into a third cell.

The resulting IRR is the discount rate at which the NPV of the project's cash flows equals zero.
