Poker equity calculator

Enter two Hold'em hands and, if you like, the flop, turn or river. The calculator deals every possible remaining board and scores both hands on each one, so the result is exact, not a simulation.

What equity means

Your equity is your share of the pot on average if all the cards were dealt out with no more betting: the chance you win outright, plus half the chance of a split pot. Aces against kings before the flop win 81.1% of the boards and split 0.38%, for equity of 81.3%. If a pot of 200 were played out this way again and again, the aces would take 81.3% of it on average.

Exact, not simulated

A simulation deals thousands of random boards and reports an estimate that moves a little every time you press the button. This one deals every board there is: before the flop that is all 1,712,304 combinations of five cards from the 48 left, on the flop the 990 turn and river pairs, on the turn the 44 rivers. The answer is the same every time and matches our matchup tables, which were computed separately in Python.

Suits matter

The exact cards change the result. Jacks against the ace and king of hearts do a little better when one of the jacks is a heart, because that is one heart fewer for the ace-king's flush. Try Jh Js and then Jc Jd against Ah Kh. That is why the calculator asks for suits, and why our tables name the exact cards.

What it does not do

Real opponents hold a range of hands, not one known hand, and pots are rarely played out with no more betting. Equity is the starting point of a decision, not the whole of it. To compare equity with the price of a call, use the pot odds calculator.
