Pick each player's cards (and a board if you want), then calculate. See exactly how often each hand wins or ties in Texas Hold'em — computed live in your browser.
How to use the equity calculator
Pick the cards. Click a slot, then a card, for each player.
Add a board (optional). Flop, turn or river — or leave it empty for a pre-flop match-up.
Calculate. Get each hand's exact win and tie percentage.
Equity shapes to memorise (favourite's %)
Click a card slot to highlight it, then click a card in the picker below to fill it. Give at least two players two cards each. Add a flop, turn, or river in the board row to narrow the result, or leave the board empty for a pre-flop matchup. Press Calculate equity and each player gets a bar with their win percentage, plus a breakdown of outright wins and ties.
A quick example: enter A♠K♠ for Player 1 and Q♥Q♦ for Player 2, leave the board empty, and calculate. You'll see the classic "race" — big slick against a pair runs about 46% to 54%. Now add a flop of K♦7♣2♠ and recalculate: pairing the king rockets Player 1 up past 85%. Watching the number move as cards land is the fastest way to build intuition for how equity shifts street by street.
How it works
Equity is how often a hand wins if the pot goes to showdown. When only a card or two are left to come, the calculator checks every remaining runout exactly — there's no estimation involved. Pre-flop and on the flop there are millions of possible boards, so it switches to a Monte-Carlo simulation: it deals tens of thousands of random runouts and tallies the winners. That's accurate to about a tenth of a percent, which is the same approach desktop equity tools use. Split pots are divided exactly between the tied hands, so the percentages always add up to 100%.
Equity vs pot odds: turning a percentage into a decision
Knowing you have 35% equity only helps if you compare it to the price you're paying. That price is your pot odds — the ratio of the call to the total pot. The rule is simple: if your equity is greater than the pot odds you need, calling is profitable over the long run. Say the pot is $100 and your opponent bets $50. You must call $50 to win $150, so you need to be good about 25% of the time. With a flush draw worth roughly 35% by the river, that's an easy, profitable call. The calculator hands you the equity side; combine it with pot odds and you have a complete, defensible decision.
What to use it for
Use it to settle after-session debates ("was my call good?"), to memorise the common pre-flop match-ups (pair vs two overcards, dominated aces, suited connectors vs a big pair), and to see how much a draw is really worth on a given board. Pair it with the Which Hand Wins? quiz to sharpen live reads, and review the poker hand rankings if any showdown result surprises you.
Frequently asked questions
What is equity in poker?
Equity is the share of the pot a hand is worth right now — the percentage of the time it would win (plus its share of ties) if all remaining cards were dealt out and the hand went to showdown. If your hand has 60% equity in a heads-up pot, it wins on average 60 times out of 100 from that spot.
How accurate is this equity calculator?
When only a card or two are left to come, it enumerates every possible runout, so the result is exact. Pre-flop and on the flop there are millions of runouts, so it runs a Monte-Carlo simulation of 120,000 hands (60,000 for three or more players), which is accurate to roughly a tenth of a percent — the same method desktop tools use.
Can I calculate hand versus a range?
Right now you enter specific two-card hands for each player plus an optional board. Range-versus-range support (AKs, QQ+, and so on) is on the roadmap. For a single matchup, specific hands give you an exact answer.
What's the difference between equity and pot odds?
Equity is how often you win; pot odds are the price you're being offered to call. Compare the two: if your equity is higher than the pot odds you need, the call is profitable in the long run. The calculator gives you the equity side of that equation.
Does it work for pre-flop all-ins?
Yes. Leave the board empty and enter both hands to get a classic pre-flop all-in equity — for example, a pair versus two overcards, or a dominated ace. It handles two to four players.
