Poker Odds Calculator
Estimate your Texas Hold'em winning chances against random hands, preflop or on any board.
About the Poker Odds Calculator
Equity is your share of the pot if all hands were played to the river: wins plus your share of ties. This calculator deals the remaining cards at random many thousands of times (Monte Carlo simulation) and evaluates every hand exactly, so results are accurate to within about ±0.5% at 20,000 deals. Opponents hold random hands; against a tight player who only plays strong hands, your equity is lower.
The formula
Equity = (wins + ties ÷ players tied) ÷ simulations
Preflop equity vs one random hand (approx.)
| Hand | Equity |
|---|---|
| AA | 85% |
| KK | 82% |
| AKs | 67% |
| AKo | 65% |
| 22 | 50% |
| 72o | 35% |
Worked example
Texas hold'em: A♠A♥ against K♣K♦, all-in before the flop
- The calculator deals the remaining five cards thousands of times
- Aces win about 82% of the time and kings about 18% (ties are rare)
- More simulations give a steadier percentage
