Bitcoin Cost Tracking - Spreadsheet Help Please

[Imbatman]

I've purchased BTC at many different price points over the past few months.  I've tracked each purchase so I know my average BTC price.

I need some help for if/when I decide to sell -- I'd like to be able to also track that, so I can determine what/if any profit/loss I need to record for tax purposes.

The selling part is tripping me up. 

Does anyone have a nice excel spreadsheet with some built in formulas you can share for me to transfer my data over to, to help me in what I am trying to accomplish?  Thanks
