What Are Poker Outs?
An out is a card that you believe will improve your hand enough to help you win. For example, if you have four hearts after the flop, there are normally 9 hearts left in the deck that can complete a flush. Those 9 cards are commonly called your flush outs.
Be careful when counting outs. A card that improves your hand is not always a clean out. It may also improve an opponent's hand. The calculator assumes that every out you enter is useful.
Example: A Flush Draw
Suppose you have two hearts in your hand and two more hearts appear on the flop. You can see 4 hearts, leaving 9 hearts unseen. Enter 9 outs and choose After the flop. The calculator will show your chance of hitting a heart on the turn, on the river if you miss the turn, and by the river overall.
How the Calculator Works
After the flop, you know 5 cards: your 2 hole cards and the 3 community cards. That leaves 47 unseen cards. After the turn, 46 cards remain unseen. The calculator uses those card counts to calculate the exact probability of hitting one or more of your outs.
The Rule of 2 and 4
Players often make a quick estimate at the table by multiplying their outs by 2 when one card remains and by 4 when two cards remain. This is called the Rule of 2 and 4. It is useful for quick mental estimates, but it is not exact. This calculator uses the actual card probabilities.
Common Draws and Approximate Outs
| Draw | Typical Outs |
|---|---|
| Flush draw | 9 |
| Open-ended straight draw | 8 |
| Two overcards | Up to 6 |
| Gutshot straight draw | 4 |
| One overcard | Up to 3 |
Important: These are only common examples. Some outs may be duplicated, blocked, or may give an opponent a better hand. Do not automatically assume every possible improving card is a clean out.
Odds Are Not the Same as Your Chance of Winning
This calculator tells you the probability of hitting the outs you enter. It does not calculate your equity against a particular opponent's hand or range. Improving your hand does not guarantee that you will win the pot.
Using Odds at the Poker Table
Knowing your chance of improving is most useful when you compare it with the price you are being offered to continue in the hand. That introduces the idea of pot odds. Beginners do not need to calculate everything perfectly, but understanding outs and draw probabilities is a useful step toward making better decisions.
