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.

Your hand Hero
Villain (blank = random)
+ extra opponents 0

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.

Board (optional)

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.

  1. Set your two cards under Your hand: click a slot, then pick a card from the grid.
  2. Give the Villain specific cards, or leave the slots blank to treat them as random. Use + extra opponents for a fuller table.
  3. Board is optional: add any shared cards already dealt (flop, turn, river).
  4. 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.

Outs to equity — the rule of 2 and 4 Chance a draw completes by the river, by number of outs.
Pair to a set · 2 outs 8%
Gutshot straight · 4 outs 16.5%
Open-ended straight · 8 outs 31.5%
Flush draw · 9 outs 35%
Flush + straight draw · 15 outs 54%

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.

Common pre-flop matchups Heads-up win percentage, no board. Brass = favourite.
A♠ A♥ vs K♠ K♦The biggest pair holds 82%18%
A♠ A♥ vs 7♦ 2♣Best hand vs worst hand 88%12%
A♠ K♠ vs Q♥ Q♦The classic race 46%54%
A♠ K♠ vs 2♣ 2♦A true coin-flip 50%50%
A♠ K♦ vs K♣ Q♦Domination 73%25%
J♠ J♦ vs A♥ K♠Pair vs two overcards 53%46%

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. Want to know which starting hands are worth entering a pot with in the first place? Our starting hand chart ranks all 169 combinations by position.

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.

Poker odds calculator FAQ

What is a poker odds calculator?

A poker odds calculator works out your chance of winning a Texas Hold'em hand. You enter your two cards, any board cards and how many opponents you face, and the calculator estimates your win equity by simulating the remaining deals. It answers the everyday question “how far ahead or behind am I in this spot?”

Is this poker equity calculator free?

Yes. This poker equity calculator is completely free, needs no account, and runs entirely in your browser. Nothing you enter leaves your device.

How accurate is the Texas Hold'em calculator?

The Texas Hold'em calculator runs 60,000 randomised runouts per spot, so results are accurate to roughly ±0.3%. The underlying evaluator is verified against exact enumeration and an independent reference. For example, it returns the textbook ~82% for pocket aces versus pocket kings pre-flop.

Can I use it as a poker hand calculator against a random opponent?

Yes. Leave the Villain's cards blank to treat them as a random hand, or add extra opponents with the stepper. Used this way the poker hand calculator shows how your hand holds up against unknown ranges, not just one specific holding.

Can I share a spot I calculated?

Every calculation builds a shareable link that reloads the exact hand, board and opponent count, handy for posting a spot in a forum or sending it to a friend.

What is the difference between odds and equity?

They describe the same thing two ways. Equity is your share of the pot as a percentage: an 82% hand wins 82 pots out of 100 in the long run. Odds express that as a ratio, like roughly 4.5-to-1. A poker odds calculator gives you the percentage; you turn it into odds when you compare it against the price of a call.

What are pot odds in poker?

Pot odds are the price you are being offered on a call: the size of the pot compared with the amount you must put in. If there is $150 in the pot and you must call $50, you are getting 3-to-1, so you only need to win about 25% of the time to break even. Compare that break-even number with your equity. Our pot odds calculator does the arithmetic for you.

What are outs and how many do I have?

Outs are the unseen cards that improve your hand to a likely winner. A flush draw has 9 outs (the 13 cards of your suit minus the 4 you can see); an open-ended straight draw has 8. Count your outs, then read the equity straight off the outs-to-equity table above.

What is the rule of 2 and 4?

A shortcut for turning outs into equity without a calculator. On the flop with two cards to come, multiply your outs by 4; with one card to come (flop to turn, or turn to river), multiply by 2. Nine flush outs × 4 ≈ 36% by the river, which is within a point of the exact 35%.

What are the odds of AA vs KK?

Pocket aces beat pocket kings about 82% of the time pre-flop heads-up (roughly 4.5-to-1). It is the biggest edge one pocket pair can have over another, and our engine reproduces the textbook figure exactly.

What is a coin-flip in poker?

A “flip” or “race” is a pre-flop match-up that is close to 50/50: most commonly a pair against two higher cards, like 2♣2♦ versus A♠K♠, which runs almost exactly even. A small pair is a very slight favourite because it starts made.

Does a bigger pocket pair always beat a smaller one?

Before the cards come, yes: the bigger pair is around an 80/20 favourite because the smaller pair usually needs to hit a set to win. But 20% is far from never, which is why a poker odds calculator is more useful than a rule of thumb.

What are the odds of hitting a flush draw?

With nine outs and two cards to come, a flush draw completes about 35% of the time by the river, a little better than 1-in-3. On the turn alone with one card to come it is roughly 19%.

What are the odds of flopping a set with a pocket pair?

About 11.8%, or roughly 1-in-8.5. It is one of the most valuable flops in Hold'em, which is why small pairs love to see a cheap flop and hit: the exact scenario the AA-vs-22 coin-flip above is built on.

Can I use a poker odds calculator while playing online?

Not in real time. Every major site (GGPoker, PokerStars and the rest) bans real-time assistance software that reads your live hand. A calculator like this one is a study tool: use it away from the table to review hands and build intuition, and it stays firmly within the rules.

Are odds calculators allowed in a live casino?

No. Phones and electronic aids are prohibited at a live poker table. Odds calculators are for study at home, not for use during a hand you are actually playing.

Does this calculator work for Omaha or other games?

This tool is built for Texas Hold'em, where each player uses two hole cards. Pot-Limit Omaha uses four hole cards and different rules, so the equities do not carry over. For now, use it for Hold'em spots.
