Anywhere I can read about doing and maintaining a excel copy for calculating the dividend and stocks returns? Or you guys keep track of the returns?

I use sgxcafe for tracking, as well as my own excel.
I rely on sgxcafe's calculations and data retrieval for the most part, but the returns I just take a look and that's it. Its all automated, and I dont mind paying 35 per year to support the app because I like to benchmark myself against selected shared portfolios (yeah when the info is there, you can't help comparing right? I'm happy if my three year return is above median)

My pet peeve is looking at the projected dividends ($ amt), I update them into excel and track the amt by month to forecast next year's dividend.
