Equity in poker is your mathematical share of the pot — the percentage of the time your hand wins if all remaining cards are dealt and no one folds. For example, pocket aces have roughly 82% equity against pocket kings preflop, meaning AA wins 82 times out of 100 on average (see Poker probability on Wikipedia). Equity shifts every street as community cards appear, and it is the foundation of pot-odds, expected-value, and GTO decision-making. Use the calculator above to compute exact equity for any hand-vs-hand, hand-vs-range, or range-vs-range matchup.

How to use this calculator

Pick a mode for each player. Exact means two specific hole cards. Range lets you select a weighted set of hands using the 13×13 matrix, the Top % slider, or a preset like UTG open or BB defend. Random uses all 1 326 combos — useful when you genuinely have no read on a villain.

Add a flop, turn, or river to see how equity shifts street by street. The equity-over-streets graph surfaces moments where a good-looking flop turns sour on a bricked turn — a critical adjustment most players miss.

Pot odds and outs

Once you know your equity, compare it against the pot odds you're getting. If villain bets half pot, you need 25% equity to call profitably. If you're drawing to a flush with 9 outs on the turn, you'll hit roughly 20% of the time on the river — so you need the right price to continue. Equity, pot odds, and outs form the three-legged stool of every postflop decision.
