Poker Odds: How to Calculate and How it Works

By August 14, 2023August 25th, 2023No Comments

Poker is a game of strategy, skill, and odds. Mastering poker odds can make you a successful player in poker game & tournament series. This blog post will help you learn about poker odds if you’re a novice or looking to improve.

Flop, Turn, and River: What Are They?

Let’s quickly review poker lingo before discussing the odds. Texas Hold’em and other poker games deal community cards in stages: the flop (3 cards), turn (4th card), and river (5th card). Players share these cards to make the finest hands.

Poker Odds?

Your poker compass is the poker odds, which calculate the possibility of specific events. These include making a winning hand and calling, raising, or folding. Poker odds help you strategize with arithmetic.

Why Do Poker Odds Matter?

Poker odds are your GPS. Drivers without them are blindfolded. Poker requires talent, not luck. Odds in poker turn guesswork into planned moves.

With or Without Poker Odds: Success Probability

Imagine two players: Player A uses gut instinct, while Player B considers poker odds. Player B’s success rate increases as they make more fact-based decisions. Poker odds are your toolkit for making better decisions.

Pot Odds

Pot odds are at the heart of poker odds. Pot odds determine the financial viability of a bet or call. This is the ratio of the pot’s current size to the cost of a call. Determine if the pot payout merits the danger.

Pot odds are 5:1. If your opponent bets $20 and the pot is $100, it would be beneficial to call the bet if the odds of completing the draw are better than 5:1. Pot odds are only one component of the puzzle.

Knowing When to Bet

A draw is a hand that could be strong with the correct card. An example of a flush draw includes four cards of the same suit and one more for a flush. Calculating the odds is involved. You might prefer to call the bet if your odds of completing the flush exceed the pot odds.

Look at Two Popular Texas Hold’em Scenarios:

1. Flush Draw

Your hand has two hearts, and the flop has two more. Your odds of completing your flush by the river are roughly 20%, with nine hearts left in the deck.

Where does 20% originate from?

This scenario involves two hearts in your hand and two more on the flop. Four hearts have been revealed.

The number of “outs” you have determines your odds of completing your flush by the river (the fifth and final communal card). “Outs” are cards that help you get a flush. You need one more heart to flush.

Now, you may use the following calculation to calculate the odds or probability of drawing one of the nine remaining hearts on the river:

Probability = Outs / Unknown Cards × 100.

Outs are 9 (remaining hearts), and unknown cards are the deck’s total minus the cards you’ve seen 45.

Probability = 9/45 × 100 ≈ 20%

You have 20% odds of flushing by the river.

Poker odds are probabilities and estimates. These calculations provide you with a general sense of your chances of hitting the desired card, helping you make game decisions.

2. Open-ended Straight Draw

The flop is 6-9-2, and you have 7-8. A straight requires a 5 or 10. Your odds of hitting a straight by the turn or river are 31.5%, with eight outs (four 5s and four 10s) left in the deck.

Understanding this 31.5%’s origin

This is an open-ended straight draw. The flop (first three communal cards) is 6-9-2 (7-8). For your straight, you need a 5 or 10. These two cards offer 5-6-7-8-9 or 6-7-8-9-10 sequences.

You need to know your “outs.” to calculate the odds of landing one of these two needed cards by the turn (the fourth community card) or river (the fifth community card). “Outs” are cards that help you get a straight.

The deck has four 5s and four 10s, giving you eight outs.

The odds or probability of drawing one of these eight outs by the turn or river can now be calculated using the same calculation as before:

Probability = Outs / Unknown Cards × 100.

The deck has 52 cards, 4 of which are unknown and 3 of which are outs.

Probability = (8/45) × 100 = 17.8%

In order to complete your straight by the turn or river, your odds of striking one of the required cards (a 5 or a 10) are 17.8%.

However, open-ended straight draws must consider the “double count.” Some players utilize a “double count” to indicate both ways a 5 or 10 can complete your straight. This computation would be:

Double-Counted Probability = (Outs / Unknown Cards) x 2 x 100

Double-Counted Probability = (8/45) x 2 × 100 = 35.6%

Implied Odds?

Poker fortune tellers are implied odds. They weigh current pot odds and future bets. They’re great for scenario drawing. If you hit your draw, your opponent may bet extra. Future gains are based on implied odds.

Benefiting from Implied Odds

Implied odds are your poker hero. They let you call even when pot odds are low. Predicting future investments and gains helps you make effective judgments.


Think of poker odds as a secret code that reveals the best choices to make. You can predict what might happen next and make better decisions when you grasp these odds. Just like a map helps you find your way, poker odds help you find your way in the game.
