Poker Odds Calculator

Select your hole cards and community cards to calculate win probability, outs, and equity. Includes a pre-flop odds reference table.

Quick Answer

To estimate your odds, count your outs (cards that improve your hand) and use the rule of 4 and 2: multiply outs by 4 on the flop (two cards to come) or by 2 on the turn (one card to come). For example, a flush draw has 9 outs, giving ~36% on the flop and ~18% on the turn.

About This Tool

The Poker Odds Calculator helps Texas Hold'em players estimate their hand strength, outs, and equity during a hand. Select your two hole cards and any visible community cards to see a real-time analysis. The pre-flop reference table shows approximate win percentages for the top 20 starting hands.

Understanding Outs and Equity

An “out” is any unseen card that will improve your hand to likely the best hand. If you hold four hearts after the flop, nine remaining hearts are your outs for a flush. Equity is your mathematical share of the pot based on your probability of winning. Comparing your equity to pot odds determines whether calling, raising, or folding is the profitable play.

Pre-Flop Starting Hand Selection

Starting hand selection is one of the most impactful decisions in poker. Premium pairs (AA, KK, QQ) and big suited connectors (AKs) are statistically the strongest starting hands. However, position at the table, stack depth, and opponent tendencies should influence which hands you play. Tight-aggressive play, entering pots with strong hands and playing them aggressively, is the foundation of winning poker strategy.

The Rule of 2 and 4

For quick mental math at the table, use the rule of 2 and 4. After the flop with two cards to come, multiply your outs by 4 for an approximate equity percentage. After the turn with one card to come, multiply by 2. This gives a surprisingly accurate estimate. For example, an open-ended straight draw with 8 outs has roughly 32% equity on the flop (8 x 4) and 16% on the turn (8 x 2).

Frequently Asked Questions

How do poker outs work?
Outs are the number of unseen cards that will improve your hand. For example, if you have four cards to a flush after the flop, there are 9 remaining cards of that suit (13 total minus 4 you can see), giving you 9 outs. The more outs you have, the better your chance of making your hand.
What is the rule of 2 and 4 in poker?
The rule of 2 and 4 is a quick way to estimate your equity from outs. After the flop (two cards to come), multiply your outs by 4 for an approximate percentage. After the turn (one card to come), multiply by 2. For example, 9 flush outs on the flop gives roughly 9 x 4 = 36% chance of making your flush.
What are the best starting hands in Texas Hold'em?
The premium starting hands are pocket Aces (AA), Kings (KK), Queens (QQ), Jacks (JJ), and Ace-King suited (AKs). Pocket Aces win approximately 85% heads-up against a random hand. Position, stack size, and table dynamics also significantly influence which hands to play.
What is pot equity in poker?
Pot equity is your share of the pot based on your probability of winning at showdown. If you have 40% equity in a $100 pot, your equity is $40. Good poker decisions involve comparing your equity to the pot odds being offered. If your equity exceeds the cost to call, it is a profitable call in the long run.
Is this calculator suitable for tournament play?
The odds and equity calculations are mathematically the same for cash games and tournaments. However, tournament strategy involves additional factors like ICM (Independent Chip Model), bubble dynamics, and pay jumps that this calculator does not account for. The raw hand equity remains accurate regardless of format.
