Equity is your hand's probability of winning at showdown against the opponent hand(s) right now, expressed as a percentage. If your equity is 65%, it means that over 100 identical situations you'd win about 65 on average. It's calculated at any point — preflop, flop, turn, or river — by counting all the remaining outs, and it converges toward certainty as the board runs out.
Equity is the starting point of every poker decision. Whether you should call, raise, or fold depends on comparing 'how often do I win' with 'how much do I have to risk relative to the pot (pot odds)'. High equity alone doesn't always mean a call is correct, and even low equity can make a call profitable when the pot odds are good.
Assign your hole cards and the opponent hands, then enter the board (flop, turn, river), and each player's win and tie percentages are computed in real time. You can line up to four hands side by side and compare their head-to-head equity.
Equity alone doesn't finish the decision. Understanding the three concepts below lets you turn the calculator's numbers into real in-game choices.
Equity is 'how often you win'; pot odds is 'the minimum win rate a call needs'. When your equity exceeds the pot odds, calling is profitable long term. For example, if the pot odds require 25% but your equity is 35%, calling is correct.
Even at 65% equity you can lose a single hand. Probabilities only realize over the long run, and the key is not to be shaken by short-run results (variance). Losing an all-in where you were the favorite is not a mistake.
You rarely realize your full preflop equity. Out of position (OOP) or against aggression you get pushed off hands and can't cash in. So when you're OOP, treat the shown equity more conservatively.
It's the probability your hand wins if the current situation runs to showdown. It's set by the number of outs (remaining cards that make your hand win) and the number of board cards left. A gutshot (inside straight draw) has 4 outs, giving roughly 17% equity by the river.
It depends. If the pot odds a call requires are below 40% (e.g., 33%), calling is profitable; if the pot odds are above 40%, folding is correct. Factoring in implied odds (extra money you'd win when you hit) can also change the decision.
No. This calculator computes win rates at any point — preflop, flop, turn, or river. Even when it's not an all-in, you can use it to check 'how good is my draw right now' and compare it against the pot odds.
