When is irr undefined

Thank you,. How do you calculate IRR in the next project. Does the result make sense? The above is made possible so that the company has a bank loan of After selling the company in year 10 the loan will be paid back bullet loan and So the investor made Awesome website you have here but I was curious about if you knew of any discussion boards that cover the same topics talked about in this article?

If you have any recommendations, please let me know. While the IRR is often an appropriate measure for determining whether an individual project is worthwhile, there are three cases where IRR may not be very useful or may yield misleading information.

First, if a project has some years with positive cash flow and some years with negative cash flow an example is on the power plant pro forma from the previous lesson , then it is possible that the IRR may have multiple values.

Mathematically, this arises because a high-order polynomial equation may have multiple non-unique roots. Second, if a project has negative total undiscounted cash flows over its lifetime, then the IRR is mathematically undefined.

In other words, some types of projects can see their NPV increase when the discount rate goes up, which is the opposite of what we would expect to happen.

If you need to, you can adjust the column widths to see all the data. Need more help? Expand your skills. Get new features first. Was this information helpful? Yes No. Thank you! Any more feedback?

In the image of the IRR function that noff provided, you see that it wants an object with two keys named "depth" and "cashFlow".

Try finance. I'm not really sure what "depth" is, but from the code, its a limiter on how many times the internal NPV function is ran.
