    Finding outputs by changing 4 variable inputs

    Hi, I'm working on a 10 year financial forecasting model for an investment
    fund. The end result is to calculate the IRR. There are 4 variable inputs I
    would like to change, and observe how the IRR changes as those inputs change.
    In other words, I would like to play with changing two different fees, the
    fund size, and the expected return, and see how changing those impacts the
    IRR.

    Is there a way to do this on one sheet without manually changing all these
    inputs? I think Scenario or Data Tables might do it, but I'm not sure.

    Thank you.

    Not sure what you are asking, but there must be some sort of formula for IRR that includes your 4 values. To see how they changes look, set up 4 cells to hold the 4 values you want to change, then set up a seperate cell to = the formula that references those four cells. To see a graph of results, set up a data table with the different inputs and results.

    As a side note, when you have a request such as yours above, try to post as much information as you can. Sample workbooks go a long way toward helping others to find solutions. Speaking for myself, I don't even know what IRR means, so it is hard to respond.
    Is your code running too slowly?
    Does your workbook or database have a bunch of duplicate pieces of data?
    Have a look at this article to learn the best ways to set up your projects.
    It will save both time and effort in the long run!
