ROI Stands for 'Return on Investment' and is a commonly used way of calculating your profits in poker. The exact method of calculating ROI will vary depending on which form of the game is played. A more useful figure for poker players may be 'hourly rate' which takes into account the time spent playing.

1) Calculating Poker ROI for Tournaments / Sit and Goes

ROI for tournaments is expressed as a percentage of your original buy-in. It is standard in poker to remove 100% (buy-in) from the calculation at the end. For example:

You play 100 tournaments each with a buy in of $10 + $1 fee and end up with a total bankroll of $1600.

ROI = (1600)/(1100) or 145% - remove the 100% (standard format) and you have a ROI of 45% for those tournaments.

2) Calculating ROI for Cash Games

ROI for cash games becomes a little more difficult. This is because you need a time frame over which to calculate your return. The standard poker format for this is to use 100 hands. For example.

You play 1000 hands of poker over a single session and make $500 profit. Your buy-in for the game st the start was $200. ROI is thus 50% per 100 hands. It is also common in poker cash games to calculate profit as the number of big blinds won per 100 hands. In this example with blinds at $2/$1 you could note your profits as 25 Big Blinds per 100 hands.
