Poker odds are calculated differently from casino game odds because poker is player-vs-player, not player-vs-house. The "house" in poker is the rake taken from each pot. This calculator computes your hand equity against any range of opponent hands, the pot odds you're being offered, and the implied odds for drawing hands.

Enter your hole cards, the board (flop/turn/river), and select one or more opponent hand ranges (or use the predefined ranges for tight/loose/aggressive play). The calculator returns your equity percentage, the chance of hitting your draw on the next card, the pot odds you need to call profitably, and the expected value of calling vs raising vs folding.

For tournament play specifically: stack-to-pot ratio (SPR) matters more than absolute stack size. This calculator includes SPR in the output so you can make better commitment decisions. For cash game play: rake structure is the primary determinant of whether a game is profitable at your stake — see our poker strategy guide for the rake calculations.
