Found this Excel Spreadsheet for keeping Track of all your Bet Types which includes Profit/loss.

Has a performance sheet which you can filter by Bet type, Sport type etc

Also has a performance graph sheet that shows month by month performance.

So much work has gone into this Spreadsheet which includes drop down menus for most columns etc.

You can get it from here if your interested:
