How the calculator works
Each hand is scored as the best five cards out of seven. With every hand known and three or more board cards dealt, it counts every possible run-out exactly. Before the flop, or with a random opponent, it deals 30,000 random run-outs.
equity = (wins + ties ÷ players tied) ÷ deals
Omaha odds
In Omaha (pot-limit Omaha, PLO) each player gets four hole cards and must use exactly two of them with exactly three board cards. Four hearts on the board do not give you a flush with one heart in hand, which is the most common Omaha misread. The calculator checks all 60 two-plus-three combinations for each hand.
Example, counted exactly over every turn and river: A♠A♥K♠Q♠ against J♦T♦9♣8♣ on 7♥6♥2♣. The aces lead now but have only 42.6%; the wrap draw, with many turn and river cards that complete a straight using two hole cards, has 57.4%. Equities run much closer in Omaha than in Texas Holdem, because every hand has more ways to improve.

Pot odds calculator
Pot odds compare what a call costs with what it can win. equity needed = call ÷ (pot + call), where the pot already includes the bet you face. If your chance of winning is higher, the call makes money in the long run.
Worked example: $100 in the pot, your opponent bets $50, so $150 is in the middle and you must call $50: pot odds of 3 to 1, a 25% break-even. A flush draw on the flop (9 outs) hits by the river 35.0% of the time, so calling makes about $19.94 on average, before any later bets.
Outs: exact odds vs the rule of 4 and 2
| Outs | Flop to river (exact) | Rule of 4 | Turn to river (exact) | Rule of 2 |
|---|---|---|---|---|
| 2 | 8.4% | 8.0% | 4.3% | 4.0% |
| 4 | 16.5% | 16.0% | 8.7% | 8.0% |
| 6 | 24.1% | 24.0% | 13.0% | 12.0% |
| 8 | 31.5% | 32.0% | 17.4% | 16.0% |
| 9 | 35.0% | 36.0% | 19.6% | 18.0% |
| 12 | 45.0% | 48.0% | 26.1% | 24.0% |
| 15 | 54.1% | 60.0% | 32.6% | 30.0% |
Exact: 1 − (47 − outs)(46 − outs) ÷ (47 × 46) from the flop, outs ÷ 46 from the turn, counting only your own unseen cards.
Questions
How do you calculate pot odds?
Divide the amount you must call by the pot after your call. Facing a $50 bet with $150 in the middle (pot odds 3 to 1) you need 25% equity; a flush draw on the flop has 35.0% to the river, so calling makes about $20 on average.
Does the calculator work for Omaha?
Yes. Choose Omaha and enter four cards per player. Each hand must use exactly two hole cards and three board cards. On a 7h 6h 2c flop, A♠A♥K♠Q♠ has 42.6% equity against J♦T♦9♣8♣, which has a wrap straight draw.
How are poker odds calculated?
By dealing out every remaining card combination, or a large random sample of them, and counting how often each hand wins or ties. Equity is wins plus a share of ties.
What is poker equity?
Your share of the pot on average if the hand were played to showdown many times. Aces against kings before the flop have about 82.6% equity.
What is the rule of 4 and 2?
A shortcut for draws: on the flop multiply your outs by 4 for the chance of hitting by the river; on the turn multiply by 2 for the next card. It overstates big draws slightly, as the table shows.
Can I leave an opponent's cards blank?
Yes. A blank hand is dealt randomly in each simulated deal, which gives your equity against a random hand.
