$Net and ROI Here's what I found. I'm not sure if it's what you're looking for. I wasn't sure what the $net is?
If you wish to put a number on your own handicapping acumen, you can calculate your own $2 ROI. If you bet $5,000 in a year and win $6,000, simply divide your winnings by half of the amount you wagered. In other words, $6,000 divided by $2,500 (half of $5,000) is $2.40, a profit of 40 cents on every $2 wager.
