Equity is a way of putting a number on a hand that has not finished. If you hold a hand and cards are still to come, your equity is the share of the pot you can expect to win on average if the remaining cards were dealt out many times. It is a long-run average, not a prediction of the next deal.
The definition in practice
Suppose that, from your current cards, you would win 40% of the time and lose 60%. Your equity is 40%. If the pot is 200, then your equity share of it is 0.40 × 200 = 80. That does not mean you receive 80 on any given hand. You win the whole 200 about four times in ten, and nothing about six times in ten, and the average works out to 80 per hand.
Equity always depends on what the opponent holds. The same hand has a different equity against different opponents, and a hand that is ahead against one holding can be behind against another. So the phrase “my hand has 60% equity” is incomplete until you say against what.
Ties
If two players share the pot, that outcome counts as half a win. Imagine a hand that wins 60% of the time, ties 10% and loses 30%. Its equity is 60% + half of 10% = 65%. Equity is the average share of the pot, so a split pot contributes its share, not a full win.
Hands versus ranges
Against a single known hand, equity can be computed by dealing out all remaining possibilities. At the table, though, you rarely know the opponent’s hand. You think about a group of hands the opponent might have, which is called a range. Equity against a range is a weighted average of the equity against each hand in it.
A simple illustration with invented numbers: suppose you have 80% equity against one holding and 30% against another, and you think the opponent is equally likely to hold either. Your equity against that range is 0.5 × 80% + 0.5 × 30% = 55%. If the opponent is three times as likely to have the stronger hand, the weights change: 0.25 × 80% + 0.75 × 30% = 20% + 22.5% = 42.5%. How many ways each hand can be held affects these weights, which is why counting hand combos matters.
Preflop equities are often described in general terms. For example, a pocket pair against two unpaired cards that are both higher than the pair is typically only a small favorite, in the region of 55% to 45% and close to a coin flip, but the exact figure depends on suits and the specific cards. Do not rely on remembered figures when exactness matters; use a calculation tool or work it out.
Equity on the flop and turn
With a draw, equity can be estimated from the number of cards that improve it. A flush draw with 9 outs, whose outs also give the best hand, has about 35% from the flop to the river, as the rule of four estimates. If the opponent already has a made hand and the draw’s outs are clean, that 35% is the draw’s equity, and the made hand has roughly 65%.
On the river, equity collapses to 0% or 100% (or a split), because no cards remain. This is why the same hand can appear in an equity chart as 35% earlier and then simply win or lose.
Equity is not profit
Equity measures your share of the pot, but profit depends on what you pay. Consider an all-in where each player puts in 100 and the pot becomes 200. With 50% equity, your share is 100, equal to what you put in, so the average result is zero. With 35% equity, your share is 70, so the average result is a 30 loss. With 65%, it is a 30 gain on average. Whether a call is worthwhile compares equity with the price of continuing, which is what pot odds measure.
Equity also assumes the hand goes to showdown without any more betting. In practice, other things change the picture:
- A player who must act first, or who is out of position, often cannot take full advantage of their equity, because the opponent controls the size of later bets and chooses when to fold.
- Hands that make strong but hard-to-spot holdings, such as hidden flush completions, may win more than their equity suggests; hands that often win only small pots may win less.
- Folding changes the calculation altogether: the share of the pot you win can be 100% if everyone folds, which is not equity but a separate source of value.
The share of equity that a hand tends to turn into actual winnings is called its equity realization. It varies by hand type and situation, and it is one reason beginners are wise not to treat raw equity percentages as final answers.
Using equity to compare hands
When two hands are compared, the one with the higher equity against the opponent’s range is not always the better play, but it is the better starting point. Equity lets you say that a hand is well ahead, slightly ahead, or behind in the long run, instead of using vague terms. It also explains why some hands lose often yet are still sound plays: a 35% hand loses most of the time, but the pot may be large enough relative to the price.
Poker is risky. Even a favorable equity share can lose on any hand, entry fees and rake reduce overall results, and wagering money can lead to losses. If gambling stops feeling like entertainment, a local support service can help.
