Pick your two hole cards to see your chances. Add board cards and opponents for a sharper picture.
Equity is calculated against opponents who play any two cards, so it does not account for how they have bet. Use it to build intuition, not as a final answer.
How to use the equity calculator
Choose your two hole cards, add the flop, turn and river if they have been dealt, and set how many opponents you face. The calculator assumes each opponent holds a random hand, which is a fair baseline when you know nothing about them. If you want to test a specific matchup (say, your ace-king against someone’s pocket queens) tick “I know one opponent’s hand”.
The result shows your chance to win, tie and lose, and your equity, which counts a tie as a share of the pot. Open “What will my final hand be?” to see how likely you are to finish with a pair, a straight, a flush and so on.
Some numbers worth memorising
| Situation (heads-up, pre-flop) | Approx. win chance |
|---|---|
| Pocket aces vs pocket kings | about 81% |
| Pocket pair vs two overcards (a “coin flip”, e.g. 8-8 vs A-K) | about 52% to 55% |
| Ace-king vs pocket pair lower than a king | about 43% to 48% |
| Dominated hand (e.g. A-K vs A-Q) | about 73% for the dominating hand |
| Random hand vs random hand | 50% |
Using pot odds and outs together
Count your outs, the unseen cards that complete your hand. Convert them to a probability (the second tab does this exactly), then compare with the equity you need from the pot odds. If your chance to hit is higher than the price requires, the call is profitable on average.
- Flush draw: 9 outs (about 35% from the flop to the river)
- Open-ended straight draw: 8 outs (about 31%)
- Gutshot straight draw: 4 outs (about 17%)
- Two overcards: 6 outs (about 24%)
Math is only part of the decision. Opponents’ betting reveals information, some outs improve a hand that is still second-best, and bets you may win on later streets (implied odds) change the picture. Treat the calculator as a way to build intuition, then practise at a free table.
Pick your cards and see your real chances. Calculate hand equity against up to eight opponents, then use pot odds and outs to decide whether a call makes sense.
Frequently asked questions
What is hand equity?
Equity is your share of the pot, on average, if the hand were played out many times. If you have 60% equity in a 100-chip pot, your hand is “worth” about 60 chips.
How are these odds calculated?
When the number of possible outcomes is small (one opponent and at most one board card to come) we count every outcome exactly. Otherwise we simulate tens of thousands of random deals with the same hand evaluator our game server uses, and show the margin of error.
What are pot odds?
Pot odds compare the price of a call to the size of the pot. If the pot is 100 and you must call 25, you are risking 25 to win 125, so you need to win at least 25 / (100 + 25) = 20% of the time to break even.
What is the rule of 2 and 4?
A fast mental shortcut for draws: multiply your outs by 4 on the flop (two cards to come) or by 2 on the turn (one card) to estimate your chance of hitting. It is slightly high for large numbers of outs, which is why we also show the exact figure.
