Need help figuring out how to solve for IRR. I've looked all over and seeing different ways to do it, however I'm not sure how to get the IRR %. I know that NPV is 0, but not sure how to calculate the rest.
Suppose your firm is considering investing in a project with the cash flows shown as follows, that the required rate of return on projects of this risk class is 8 percent, and that the maximum allowable payback and discounted payback statistic for the project are three and three and a half years, respectively.
Time 0 1 2 3 4 5
Cash flow -100,000 30,000 45,000 55,000 30,000 10,000
Use the IRR decision rule to evaluate this project; should it be accepted or rejected and why?
