Poker Odds Calculator
You pick the hands, the board and any dead cards, and the tool returns the win probability and the tie share for every player still in the pot. Four games run from one set of tabs, and the pot odds block turns the same figures into the price of a call. The percentages come from played-out card combinations, and the maths was checked against an independent Python reference.

How the calculator works – and what it doesn’t cover
Exact or simulated: the calculator first counts how many ways the unknown cards can be dealt. If there are few enough (up to roughly four million hand evaluations), every single combination is played out and the figures are exact – for example, all 1,712,304 boards when two known Hold’em hands meet before the flop. Otherwise it deals 50,000–300,000 random runouts (Monte Carlo). The margin of error shown is a 95% interval: 1.96 × √(p × (1 − p) ÷ n).
Win, tie and equity: “win” means the hand is best on its own at showdown. “Tie” means two or more players split the pot. Equity is your chance of winning plus your share of split pots (divided equally among the players who split).
The variants: in Texas Hold’em, the best five of your two hole cards and the five board cards count. In Omaha, the hand must use exactly two of your four cards and three from the board. In Seven Card Stud, the best five of your seven cards count, and dead cards are removed from the deck. In Five Card Draw, your final hand is counted exactly over every possible draw; an opponent is simulated with the standard rule: stand pat on a straight or better, hold three of a kind, two pair or a pair, otherwise hold four to a flush, then four to an open-ended straight, and otherwise just the highest card.
Pot odds: equity needed = amount to call ÷ (the pot including your opponent’s bet + amount to call). The comparison applies to a single call with no further betting later in the hand.
What the calculator doesn’t cover: ranges (a set of possible hands for your opponent), betting rounds and rake, hi/lo variants, Razz and decks with jokers. Unknown opponent hands are completely random hands.
How to use the poker odds calculator
Five steps. If the game itself is still new to you, the flow is covered in our guide to how to play poker; the calculator starts from the point where you already know which cards are yours.
- Choose the game tab – Texas Hold’em, Omaha, Seven Card Stud or Five Card Draw. Each tab changes how many hole cards a seat gets and whether there is a board.
- Enter the known hands. Two cards per player in Hold’em, the full four in Omaha, five private cards in Five Card Draw.
- Add the board where the game has one. Hold’em and Omaha use community cards, so add the flop, turn or river as they arrive.
- Mark dead cards – anything you have seen folded, burned or shown. They come out of the deck before anything is dealt.
- Read the output. Every player gets a win percentage, a tie percentage and an equity figure, and the pot odds block below converts those numbers into the amount you can call.
Step four is the one players rush: every dead card you mark is taken out of the deck before the odds are counted.
Poker odds, pot odds and equity in plain terms
Three ideas get mixed together, so it helps to keep them apart. Poker odds describe the chance of something happening – a card arriving, a draw completing. Pot odds compare the cost of a call with the pot you would win. Equity is your share of that pot if the hand were played out from here with everyone’s cards face up.
Our example: the pot holds $60 and your opponent bets $20. You are being asked to put in $20 to win $80, so the call needs 20% equity to break even: your $20 against a final pot of $100. Win more often than that and the call makes money over time; below 20% it gives money away. The odds calculator hands you the equity figure, and the pot odds block does the division.
Outs are the cards that improve your hand, and most players can count them in their head. Comparing the count to the price is the step that gets skipped, and that is where a hand odds check earns its keep.
Counting outs and the rule of 2 and 4
The rule of 2 and 4 gets you close without a screen. Multiply your outs by 2 for the approximate percentage chance to hit on the next card, or by 4 from the flop to the river with two cards to come. A flush draw on the flop has 9 outs, which works out at about 35% by the river. An open-ended straight draw has 8 outs, about 31.5% by the river.
Use the rule for speed, then run the hand through the calculator afterwards. For the open-ended straight draw the rule of 4 gives 32%, close to the exact 31.5%. Hand rankings matter here as well, since a draw that completes into a second-best hand is worth less than the raw percentage suggests, and our poker hand rankings page sets out the order from top to bottom.
Four games in one calculator
Texas Hold’em uses two hole cards each plus five community cards, and the betting order is covered in our Texas Hold’em rules if you need a refresher. Omaha keeps the board but hands every player four hole cards, and you must use exactly two of them and exactly three community cards.
Seven Card Stud has no community cards at all: your best five come from your seven cards. Dead cards are removed from the deck, which matters because in stud you can see some of them. Five Card Draw gives you five private cards and one draw to swap cards. Your finished hand is calculated exactly over all possible draws, and the opponent is simulated with a standard rule – stand on a straight or better, keep three of a kind, two pair or a pair, otherwise go for four to a flush, then four to an open-ended straight, otherwise keep the highest card.
How accurate is it?
The engine counts first. It works out how many ways the unknown cards can be dealt, and if that number is small enough – up to about four million hand evaluations – every combination is played out and the figures are exact. Two known Hold’em hands meeting before the flop run through all 1,712,304 possible boards, and what you read afterwards is a precise number, not a sample.
Past that threshold the calculation switches to Monte Carlo, drawing 50,000 to 300,000 random deals and reporting a 95% margin of error: 1.96 × √(p × (1 − p) ÷ n). More deals tighten the range, so a simulated win probability arrives with a visible band of uncertainty attached.
Questions players ask
Can I use a poker calculator while playing?
Not in a live card room. Using a calculator during a live game is not allowed in card rooms. The workable pattern is to study with it between sessions – review the hands that confused you, check whether the call was priced correctly, close the tab before you sit down. Our live poker in NZ section explains how the tables here are run.
What is equity in poker?
It is your share of the pot based on how often your hand wins and how often it ties, with the unknown cards still unknown. Three players in and you hold 45% equity: you own 45% of that pot in expectation. Set it beside the pot odds and you have a decision. The poker section collects the rest of the beginner material, including Texas Hold’em rules if the betting rounds are still fuzzy.
Is the calculator free?
Yes, it runs on this page with no account, no email address and nothing to install, and you can leave a hand set up while you read the explanations above. To get real use out of a poker calculator, run the same spot twice – once with dead cards removed, once without – and watch how far the equity figure travels.
