Poker Probability & Texas Hold'em FAQ

A poker odds calculator estimates your probability of winning a hand in Texas Hold'em based on the known cards (your hole cards and any community cards). It simulates thousands of random outcomes to give you an accurate win/tie/loss percentage.

By default we run 10,000 simulations, which gives results within ±1% of the true mathematical probability. More simulations (up to 50,000) reduce variance but may take slightly longer. The error margin is negligible for practical play.

Win: Your best 5‑card hand beats all opponents. Tie: You tie (chop the pot) with at least one opponent and no opponent has a better hand. Loss: At least one opponent has a stronger hand. Percentages always sum to 100%.

Yes – the board can have 0 to 5 cards. If you set only your two hole cards (pre‑flop), the calculator will show your raw hand equity against random opponents. Adding flop/turn/river cards refines the odds.

Because the tool uses random sampling (Monte Carlo). Each run uses a new random seed, so small variations are expected. Run more simulations for greater stability.

The chance of receiving a pocket pair (e.g. AA, KK) is exactly 5.88% (or 1 in 17). Suited cards appear about 23.5% of the time, and two unpaired, unsuited cards the remaining ~70.6%.

It looks at the best 5‑card combination from any 7 available cards (your two hole cards + five community cards) using the standard poker hand rankings: Royal/straight flush, four of a kind, full house, flush, straight, three of a kind, two pair, one pair, high card.

This calculator is designed specifically for Texas Hold'em (2 hole cards + 5 community cards). Omaha (4 hole cards, must use exactly 2) requires a different evaluation logic and is not yet supported.

Set the slider to match the number of active players you are facing (1‑9). The more opponents, the lower your win probability – even with a strong hand. This helps you make better fold/call decisions.

Currently the calculator assumes opponents have random unknown hands. For exact heads‑up equity against a known hand you would need a different tool. This version gives you “equity against random opponents”.
