What is poker equity?
Equity is your share of the pot based on how often your hand wins at showdown. If you hold 60% equity against a single opponent, your hand will win roughly 6 times out of 10 if the remaining cards run out repeatedly. It is the foundation for almost every profitable decision in poker.
How to calculate pot odds
Pot odds are the price you are being offered to continue: pot odds = bet / (pot + bet). For example, calling 10 into a pot of 30 means risking 10 to win 40, so you need about 25% equity to break even. Compare that required number to your actual equity to decide whether a call is profitable.
Equity vs pot odds
Pot odds tell you the minimum equity a call requires, while equity tells you how often you actually win. When your equity is greater than the required equity implied by the pot odds, calling is profitable in the long run.
Common draws and their outs
Counting outs is the fastest way to estimate equity on the fly. A flush draw has 9 outs, an open-ended straight draw has 8 outs, a gutshot straight draw has 4 outs, and two overcards give you 6 outs. Multiply your outs by 4 on the flop or by 2 on the turn for a quick percentage to hit by the river.
Common mistakes
The biggest leaks come from counting dirty outs that complete a better hand for your opponent, and from ignoring reverse implied odds — the money you lose when you hit but are still beaten. Players also forget to adjust for multiway pots, where your equity is split among more opponents, and they call draws without a clear plan for what to do on the river.
