How to Use Our Poker Odds Calculator

Enter your cards, your opponents' cards, and the board cards to see your chance of winning the hand. You can also check pot odds to know if a call is worth it.

Hero Hole Cards: Click the two card slots under "Hero" to select them. Then click the cards you hold from the deck below. These are your two private cards.

Opponent Hole Cards: Click the card slots under "Villain" to add your opponent's cards. If you do not know their cards, leave the slots empty. The calculator will treat them as random. Click "Add Opponent" to add up to 9 opponents.

Community Cards (Board): Add the three Flop cards first. The Turn slot unlocks after the Flop is filled. The River slot unlocks after the Turn is filled. Click a placed card to remove it and send it back to the deck.

Dead Cards: Add any cards you know are out of play, such as folded hands you saw. Click "Add Slot" if you need more dead card slots. These cards will not appear in any simulation.

Pot Size: Type the total amount of chips or money in the pot right now. This is used to figure out your pot odds. If you need help converting those odds into a percentage, our tool handles it automatically.

Bet to Call: Type the amount you must put in to stay in the hand. The calculator compares this to your win equity and tells you if the call is profitable or not.

Calculate Button: Press "Calculate" to run the simulation at any time. Results update with your win chance, tie chance, and total equity for each player. The deck also highlights helpful outs in green and harmful cards in red once the flop is dealt.

New Hand Button: Press "New Hand" to clear all cards and start over with a fresh setup.

What Is Poker Equity?

In poker, equity is your share of the pot based on how likely you are to win the hand. If you have a 60% chance to win, your equity is 60% of the pot. This number changes as new cards are dealt on the board. Knowing your equity helps you decide whether to bet, call, or fold. Equity is closely related to expected value (EV), which measures how much a decision is worth over the long run.

How Poker Hand Rankings Work

Texas Hold'em uses a standard 52-card deck. Each player gets two private cards called hole cards. Five shared cards, called community cards, are dealt face up on the board. You make the best five-card hand using any combination of your hole cards and the board. Hand rankings from strongest to weakest are: Royal Flush, Straight Flush, Four of a Kind, Full House, Flush, Straight, Three of a Kind, Two Pair, One Pair, and High Card. If you enjoy card-game strategy tools, our Blackjack Calculator applies similar math to twenty-one.

Understanding Pot Odds

Pot odds tell you how much you need to win to make a call worth it. You compare the size of the bet to the total pot. If the pot is $100 and you must call $50, you need to win at least 33% of the time to break even. When your equity is higher than the pot odds requirement, calling is a smart play. When it is lower, folding saves you money over time. For sports bettors, our Betting Odds Calculator applies the same logic to wagers outside the poker table.

What Are Outs?

An out is any unseen card that can improve your hand enough to take the lead. For example, if you need one more heart to complete a flush, the remaining hearts in the deck are your outs. Counting outs gives you a quick way to estimate your probability of winning on the next card. Card-game players who want to dive deeper into draw odds may also find our Yu-Gi-Oh Probability Calculator and Hypergeometric Calculator useful for understanding similar draw-based math.

Dealing Stages in Texas Hold'em

A hand moves through four stages. Pre-Flop is when you only see your two hole cards. The Flop puts three community cards on the board. The Turn adds a fourth card, and the River adds the fifth and final card. Your equity becomes more certain with each new card because fewer unknown cards remain. For a quick side-by-side look at how each street shifts your odds, our Poker Odds Calculator provides a focused equity breakdown you can use alongside this tool.

Formulas used

Player Equity (Monte Carlo)

E_i = \frac{1}{N} \sum_{s=1}^{N} c_i^{(s)} \times 100\%, \quad c_i^{(s)} = \begin{cases} 1 & \text{sole winner} \\ \frac{1}{|W^{(s)}|} & \text{tied winner} \\ 0 & \text{otherwise} \end{cases}

Win Probability

P_{\text{win},i} = \frac{W_i}{N} \times 100\%

Tie Probability

P_{\text{tie},i} = \frac{T_i}{N} \times 100\%

Pot Odds — Required Equity to Call

E_{\text{required}} = \frac{B}{P + B} \times 100\%

Profitable Call Condition

\text{Profitable} \iff E_{\text{hero}} \ge E_{\text{required}}

Made-Hand Category Probability

P(\text{category}_k) = \frac{n_k}{N} \times 100\%

Frequently asked questions

How many simulations does the poker calculator run?

The calculator runs between 4,000 and 12,000 simulations depending on how many players are at the table. With 2 players it runs about 12,000. With more players it uses fewer simulations to stay fast. This gives you accurate results in just a few seconds.

Can I use this calculator on my phone?

Yes. The calculator is built to work on mobile devices. The card deck scrolls sideways so you can see all 52 cards. Card slots and buttons are large enough to tap with your finger.

What happens if I leave an opponent's cards empty?

The calculator treats empty opponent hands as random unknown cards. Each simulation deals two random cards from the remaining deck to that opponent. This is useful when you do not know what your opponent holds.

What do the green and red highlights on the deck mean?

Green cards with an up arrow are helpful outs. If that card comes next, Hero takes the lead. Red cards with a down arrow are harmful cards. If that card comes next, Hero loses the lead. These highlights only show after the flop is dealt and at least one opponent has known cards.

Why are the Turn and River slots locked?

The slots unlock in order. You must fill all three Flop cards before the Turn slot opens. You must fill the Turn before the River opens. This matches how cards are dealt in a real poker game.

How do I remove a card I already placed?

Click on the placed card in its slot. It will be sent back to the deck and the slot will become empty again. You can then place a different card there.

What does the hand strength bar show?

The hand strength bar rates how strong your current hand is on a scale from very weak to very strong. Before the flop it looks at your hole card combo. After the flop it factors in your made hand plus any flush or straight draws you might have.

What is the difference between win rate and equity?

Win rate is how often you win the pot outright. Equity includes your wins plus your share of tied pots. For example, if you win 40% of the time and tie 10% of the time splitting the pot two ways, your equity is 45%.

How do I add more than one opponent?

Click the Add Opponent button in the Players section. You can add up to 9 opponents for a total of 10 seats. Each new opponent gets two card slots you can fill or leave empty.

What are dead cards and when should I use them?

Dead cards are cards you know are out of play but are not in anyone's hand. For example, if you saw a player fold and flash a card, mark it as dead. The calculator removes dead cards from the deck so they never appear in any simulation.

What does the equity shift timeline chart show?

The timeline chart shows how each player's win equity changes from pre-flop through the flop, turn, and river. It helps you see which street helped or hurt each player the most. The chart appears after you deal at least three flop cards.

Does the calculator work for games other than Texas Hold'em?

No. This calculator is built only for Texas Hold'em. It uses a 52-card deck, two hole cards per player, and five community cards. It does not support Omaha, Stud, or other poker variants.

How accurate are the results?

The results are very accurate for practical use. With thousands of simulations the equity numbers are typically within 1 to 2 percent of the true value. When all cards are known and no random dealing is needed, the calculator gives an exact result.

Can I rename the players?

Yes. Click the name field next to any player and type a new name. The name will update in the equity timeline chart and throughout the calculator.

What does the made-hand probabilities panel show?

Click the Made-hand probabilities button under any player to expand a table. It shows the chance that player ends up with each hand type from Royal Flush down to High Card based on the simulations.

Does the calculator save my hand history?

No. The calculator does not save or store any data. When you press New Hand or close the page, all cards and results are cleared. You will need to re-enter your cards each time.
