**How do I calculate the internal rate of return?**

ROI is the percentage increase or decrease of an investment from beginning to end. It is calculated by taking the difference between the current or expected future value and the original beginning value, divided by the original value and multiplied by 100.

**How to calculate internal rate of return (IRR) in Excel?**

Calculating the internal rate of return can be done in three ways: Using the IRR or XIRR XIRR Function The XIRR function is categorized under Excel Financial functions. The function will calculate the Internal Rate of Return (IRR) for a series of cash flows that may not be periodic. If the cash flows are periodic, we should use IRR Function.

### What is the IRR (compound rate of return) for Machine 2?

We can be confident with an IRR of 20.04%, but if you are really picky, you may work even further to get a more exact IRR (in this case, you would get something like 20.03985%). This means that our IRR, or compound rate of return, for Machine 2 is 20.04%.

**Why is my IRR higher than 10%?**

This means the net present value of all these cash flows (including the negative outflow) is zero and that only the 10% rate of return is earned. If the investors paid less than $463,846 for all same additional cash flows, then their IRR would be higher than 10%.

**What is the net present value of the IRR?**

When calculating IRR, expected cash flows for a project or investment are given, and the NPV equals zero. The initial cash investment for the beginning period will be equal to the present value of the future cash flows of that investment (cost paid = present value of future cash flows. Hence, the net present value = 0).
