The Q-ratio (also known as Q number or just Q) is used in poker tournament strategy. It is also known as the "weak force." The Q-ratio describes the relation of the player's stack to the tournament players' average stack. A low Q-ratio implies disadvantage against opponents. Q-ratio on freezeouts is calculated using the following method.

$Q\; =\; frac\; \{currentChips\}\; \{startingChips\}\; times\; frac\; \{currentNumPlayers\}\; \{startingNumPlayers\}$

On rebuy and add-on tournaments, the calculation method is somewhat more complex:

$Q\; =\; frac\; \{currentChips\}\; \{startingChips\}\; times\; frac\; \{currentNumPlayers\}\; \{startingNumPlayers\; +\; numRebuys\; +\; numAddOns\}$
