Poker Odds Calculator
Calculate winning probabilities and pot odds
About the Calculator
Poker decisions feel fast, but the odds decide the long run. This calculator helps you see your win probability, draw odds, and pot odds in one place, so each decision is grounded in math. Enter your hole cards, add community cards, and set the number of opponents to see how your equity changes street by street. It also compares pot odds to your hand odds so you can tell when a call is profitable. Use it to study spots you play often or to build intuition away from the table. The goal is not perfect play, it is consistent, informed decisions.

Understanding Expected Value (EV)
+EV (Positive Expected Value): Over many hands, this play makes money on average. Even if you lose this hand, it's the right decision mathematically.
-EV (Negative Expected Value): This play loses money long-term. Even if you win this hand, repeating this decision will cost you money over time.
💡 Professional poker is about making +EV decisions consistently, not winning every hand.

Examples
Pocket Aces (AA) pre-flop vs 1 opponent
About an 85% win rate.
Flush draw on flop (9 outs)
About 35% to hit by river, about 18% on the turn.
Pot odds 3:1, hand odds 4:1 to hit
FOLD. Pot odds do not justify the call.
Pot odds 5:1, hand odds 4:1 to hit
CALL. The call is profitable long-term.
💡 Tips
- •Pot odds = (Bet you must call) / (Pot after you call). E.g., call $50 into $200 pot = $50/$250 = 1:5 = 20%
- •If pot odds > hand odds, calling is mathematically profitable
- •Flush draws have ~35% equity with 2 cards to come, ~18% with 1 card
- •Open-ended straight draw = 8 outs = ~32% with 2 cards, ~17% with 1 card
- •Position matters - being last to act is worth 10-15% equity
🎉 Fun Facts
- •Pocket Aces win ~85% heads-up but only ~35% against 8 opponents
- •The most common pre-flop all-in is AK vs QQ (roughly 50/50, slight edge to QQ)
- •Professional players focus on long-term expected value (EV), not individual hand results
- •Recommended bankroll: 20-30 buy-ins for cash games, 100+ for tournaments
