Hello Everyone,

Here is what I am trying to accomplish. First, I have named the table above as tblData. Based on the data table above, I would like to be able to select the dates of 1/4-1/8 through a slicer and have the following occur:

1. On the first date selected, multiply by the first date selected by 2; 4 x 2 = 8
2. for every other date selected, the previous entry will then be compounded by an interest rate of 10%; for example, 1/5/17 = 8 *(1+.10) and 1/6/17= 8.8 * ( 1+.10)

I know one way to start solving the problem is to utilize a Cumulative total DAX formula which I have succesfully utuilzied below.

SelectedCumulativeTotal:=CALCULATE(SUM(tblData[amounts]),FILTER(ALLSELECTED(tblData[date]),tblData[date]<=MAX(tblData[date])))

I'm just having trouble with the last two conditions I'm trying to accomplish.

Any suggestions/help would be greatly appreciated.

Thank you very much.
