IRR formula
Hi,
I have dates in column A, and payments into a fund in column B. The payments are not uniform and the dates are random, so I want to calculate the IRR, based on todays date. One way is to put in column C the payment and the formula B1*(1+$D$1^(Today()-A1)/365)) for all the rows and do a goal seek on D1. The goal seek on the value today, which I know + comes from another source. Is there a way to do this in one formula, I tried using arrays and sumproduct but could not figure anything out? Thanks for your help. |

IRR formula
You want the XIRR function. It's in the Analysis Toolpak which you may need to
load with ToolsAddins. Feed it your cash flows and your dates and, voila, it will return the IRR. -- Regards, Fred "Jeff" wrote in message ...
