I have a stream of cash flows for a financial model that I am building (pasted below). I am trying to calculate the IRR of the Gross and Net lines. For the Gross line, I entered the following formula =XIRR(G19:AD19,G17:AD17,0.5) and I get the result of 47.16%. I then try to verify that XIRR...
Is it possible to have a negative rate with the XNPV function?
My accountancy knowledge is not much above zero, but I am trying to help a friend, who's Excel skills are almost zero, so any help gratefully received.
