Poker Odds Calculator: free Texas Hold’em equity & hand calculator
Set your hand, your opponents and any board cards, and this poker odds calculator gives you instant Texas Hold’em win-equity. It runs entirely in your browser: no sign-up, and nothing you enter leaves your device.
These play with random unknown cards, so they have no card slots — they just add players to the table (your win chance drops as the number rises). To give an opponent specific cards, use the Villain slots above.
Click a card slot above, then pick a card below.
How this poker odds calculator works
In Texas Hold’em each player holds 2 private cards and shares up to 5 board cards. The best five-card hand wins. This poker odds calculator tells you your chance of winning before all the cards are out.
- Set your two cards under Your hand: click a slot, then pick a card from the grid.
- Give the Villain specific cards, or leave the slots blank to treat them as random. Use + extra opponents for a fuller table.
- Board is optional: add any shared cards already dealt (flop, turn, river).
- Press Calculate equity. Each player’s percentage is their chance to win.
What is “equity”? It’s your chance of winning if the remaining cards were dealt at random: e.g. 82% means you’d win about 82 times out of 100. The tool estimates it by simulating tens of thousands of deals in your browser (accurate to about ±0.3%). A split pot counts as a shared win.
A free Texas Hold’em equity calculator that runs in your browser
Reviewing a hand history, or settling a table argument? A good poker odds calculator turns a tricky spot into a clear number. This free poker odds calculator uses a Monte-Carlo engine: it deals the unknown cards tens of thousands of times and counts how often each hand wins, so it returns a reliable percentage rather than a rough guess. Because everything runs locally, the Texas Hold’em calculator is instant and private: there is no server round-trip and no account, and nothing you enter ever leaves your device. You will also see the same tool searched for as a texas holdem calculator, without the apostrophe. Same game, same math.
Most players reach for a poker equity calculator in three situations: to check a big all-in they were unsure about, to see how much a draw is really worth before calling a bet, and to study how their starting hands run against a typical opponent. This tool covers all three: it is a full poker equity calculator for exact hand-versus-hand spots, and, with a hand left blank, a quick texas holdem calculator against a random range.
Use it as a poker hand calculator for any spot
The same tool doubles as a poker hand calculator: enter two specific hands to see a head-to-head like pocket aces versus ace-king, or leave a hand blank to test your holding against a random range. Add opponents and the poker hand calculator recomputes how your equity drops as the table fills. A hand that is a strong favourite heads-up can become a coin toss against three or four players. Pre-flop, on the flop, turn or river, the Texas Hold’em calculator handles every street, so you can watch your equity move as each board card lands.
Why trust this poker odds calculator
Accuracy matters in a poker odds calculator, so the engine behind this equity calculator is verified against exact enumeration of every possible board and cross-checked with an independent evaluator over hundreds of thousands of matchups. It reproduces the well-known benchmarks (pocket aces beat pocket kings about 82% of the time pre-flop), which is how you know the free Texas Hold’em calculator is giving you honest numbers. The same verified evaluator powers the pre-flop match-up table further down this page, so the odds you read here are the odds the poker hand calculator computes.
Reading your Texas Holdem hand: equity, pot odds and outs
A poker odds calculator is only useful if you know what to do with the percentage it returns. Three ideas turn that number into a decision: your equity, your pot odds, and your outs. Get comfortable with all three and the calculator stops being a curiosity and becomes a genuine study tool.
What equity really means
Equity is your rightful share of the pot, expressed as a percentage. If the poker equity calculator says you are 60%, then over many repetitions of that exact spot you would win 60% of the pot on average. You will not win any single hand 60% (you win it or you lose it), but the percentage is the north star every long-term decision is measured against.
Pot odds — when a call actually pays
Pot odds compare the price of a call with the size of the pot. If the pot is $150 and you must call $50, you are risking $50 to win $200, which is 3-to-1, or a break-even point of 25%. If your equity from the calculator beats that break-even number, calling is profitable; if it does not, folding is correct. Our dedicated pot odds calculator turns any bet-and-pot into a break-even percentage so you can compare it against your equity in one glance.
Counting outs and the rule of 2 and 4
When you are drawing, your equity comes from your outs: the unseen cards that make your hand. A flush draw has nine outs; an open-ended straight draw has eight. You do not always have a calculator open at the table, so memorise the shape of the chart below. The rule of 2 and 4 is the shortcut: multiply outs by four on the flop (two cards to come) or by two with a single card to come. Nine flush outs times four is about 36%, within a point of the exact figure the poker odds calculator returns.
Odds to complete by the river, computed by exact enumeration of the remaining cards; the rule of 2 and 4 approximates them.
Implied odds
Pot odds only count the money in the middle right now. Implied odds add the money you expect to win on later streets if you hit. A flush draw that is a hair short on raw pot odds can still be a clear call when a made flush is likely to win a big bet on the river. The calculator gives you the raw equity; implied odds are the judgement you add on top.
Common Texas Hold’em matchups and their odds
Some spots come up so often that the numbers are worth knowing by heart. Every win percentage below was computed with this page’s own engine, so you can reproduce any of them in the poker odds calculator at the top: set the two hands, leave the board empty, and press calculate.
Win % over 60,000 simulated runouts with this page’s engine, cross-checked against exact enumeration. Ties are omitted, so rows may not total 100%.
Read together, the table tells the story of most all-ins in Hold’em. A dominating ace (AK over KQ) is a big favourite. A pair against two overcards is a genuine race that the pair wins just over half the time. And the smallest edge of all (a low pair against two big cards, like the classic coin-flip) is close enough to even that variance decides it.

Using an odds calculator to actually improve
The players who get the most from a poker odds calculator do not open it mid-hand. They use it afterwards. Flag the hands you were unsure about, rebuild the spot in the calculator, and check whether your read was right. Over a few sessions you stop needing the tool for the common spots because you have internalised the numbers. That is the whole point.
Two habits pay off quickly. First, study your draws: plug in the flop and see how often your draw gets there, then compare it against the price you were offered. Second, think in ranges, not single hands: leave the opponent blank so the poker hand calculator scores you against everything they could hold, which is closer to how the hand really plays than assuming they have exactly one holding. If you are still learning what beats what, our poker hand rankings guide and the hand-ranking trainer drill it until it is instant.
Are poker odds calculators allowed?
Away from the table, absolutely: a calculator like this one is a study tool, and studying is how every serious player gets better. The rules only bite when you try to use one during a hand you are playing. Every major online room bans real-time assistance (RTA) software that reads your live cards and tells you what to do; getting caught means a frozen account and forfeited funds. In a live casino, phones and electronic aids are simply not allowed at the table.
So the honest answer is: use a poker odds calculator all you like to learn, review and settle debates, but never as a crutch in a live pot. This tool is built for exactly that: open study, not in-game assistance. When you are ready to put the theory to work, our poker room reviews rank where the games are worth playing.
