So we are just starting on our poker career and we still can not afford those complicated tracking software.  Well, do not fret.  I am sure you have some sort of spreadsheet software installed on your PC or Laptop.  This simple spreadsheet keeps track of my running Bankroll Balance, my current ROI per Buy-In, and a few other things that I might want to know. This ain't Poker Tracker but it does give me a good idea how my game is doing.  I can also make a graph out to give me a visuals of my ups and downs.

The $25 is my starting bankroll.  You need to input the data on on columns A - F. The first line shows the formula i used to compute my Balance, Buy-In Total, etc. on columns G - L starting on Game 1. 

            =G4+(F5-C5) =H4+C5 =I4+F5 =J4+(F5-C5) =J5/A5 =(J5/H5)
