Whether you are facing an All-In preflop or trying to decide if you should call a bet on the Turn, knowing your math is the difference between gambling and investing. Our free Texas Hold’em Odds Calculator allows you to calculate the exact winning percentage (Equity) of your hand against one or multiple opponents.
This tool uses a Monte Carlo simulation engine to run thousands of virtual hands in seconds, giving you professional-grade accuracy for Preflop, Flop, Turn, and River scenarios.
How to Use the Poker Odds Calculator
- Select Player Cards: Click on the empty card slots for “Player 1” and “Player 2” to open the card picker. Select the Rank and Suit.
- Add Opponents (Multiway): If you are in a multi-way pot, click the “+ Player” button to add up to 6 players total.
- Select Board Cards:
- Preflop: Leave the board empty to see starting hand equity.
- Flop: Select the first 3 community cards.
- Turn/River: Add the 4th and 5th cards to see how the odds change.
- Calculate: Click the green button. The tool will display the Win % (how often you scoop the pot) and Tie % (split pot probability).
Understanding the Results
Preflop Equity Examples
- Pocket Aces (AA) vs. Random Hand: 85% vs 15%. This is the strongest position in poker.
- Coin Flip (AK vs QQ): ~43% vs ~57%. This is a classic race scenario.
- Dominated Hand (AK vs AQ): ~74% vs ~26%. The AQ is in big trouble because the King “dominates” the Queen.
Postflop Math
Once the Flop hits, equities change drastically. If you have a Flush Draw (4 cards to a flush), you generally have about a 36% chance of hitting it by the River. Use the calculator to see if your “Pot Odds” justify a call.
Frequently Asked Questions (FAQ)
How accurate is this calculator?
This tool runs a Monte Carlo simulation (approx. 2000 iterations per click). This provides accuracy within +/- 1%, which is more than enough for strategic decision-making. It accounts for “dead cards” (cards already held by other players) automatically.
What is “Equity”?
Equity is your rightful share of the pot. If the pot is $100 and the calculator says you have 75% Win probability, your “Equity” is $75. If you can call a bet for less than your equity gained, it is a profitable play.
Can I calculate odds for Omaha?
This specific tool is designed for Texas Hold’em. Omaha requires a different logic because players hold 4 cards and must use exactly 2 of them. Please check our menu for the Omaha calculator (coming soon).
