    I'm trying to calculate a return over time, over one fixed data point, by month...

      I would like to use data from two tabs of excel, the first I have been able to calculate a margin dollar number by month over time.  I now want to join in the other data, which is the total amount that was purchased, and then I want to calculate between the two data sets, by month, how much we have recovered from our initial investment.  Please help!!
