Equity

Your share of the pot if all the cards were dealt out right now, as a percentage.

Last updated

What it means
Equity is how often your hand ends up winning, counting ties as half a win, if nobody bets again and the board runs out.
How it is calculated
Deal every possible remaining board, or a large random sample of them, and count how often each hand wins. Against a range, average over every hand in the range.
Worked example
Aces against kings all-in before the flop win about 82% of the time, so aces have 82% equity. Ace-king suited against a pair of twos is close to a coin flip at about 50%.
Why it matters
Equity decides whether a call is profitable. Compare it with the required equity: if you have more than you need, calling makes money.
