Blackjack Odds & Probabilities - Boost Your Winning Edge

Q: Is blackjack based on luck or skill?

Luck plays its part in the game, but it all comes down to your skill to use all the tools, like charts, bust tables, and strategies, to lower the house advantage and maximize your returns.

Q: What are the odds of winning blackjack?

If the house edge is set at 0.5%, you have a 42% chance of winning. The typical payout is 1:1, unless you get natural blackjack right from the start, securing a 3:2 win.

Q: What is the 17 rule in blackjack?

The 17 rule states that the dealer must not take another card if faced with a player’s hand of 17 or higher. If the dealer hits (takes another card), that may increase the house edge.

Q: What is the most profitable blackjack strategy?

The most profitable blackjack strategy would be to combine card counting with the basic blackjack strategy. We recommend putting this combo to use at tables that allow the dealer to stand on soft 17, doubling after splitting, and 3:2 payouts for natural blackjack.

Q: Are blackjack side bets worth it?

If you recognize the potential for higher payouts with side bets in blackjack, go for it. However, betting side bets isn’t a profitable long-term strategy, as it involves a higher house edge and greater risks.

Q: Which blackjack rules offer the best odds?

A game where the blackjack payout is 3:2, and where the dealer is required to stand on soft 17, gives a bigger edge to the players. Also, single or double deck versions are easier for counting cards.

Q: Can card counting improve the odds of winning blackjack?

Yes, card counting can boost your odds of winning in blackjack by lowering the house advantage from 0.5%-2.7% to 0.5%-1.5%.

Q: Is the blackjack odds calculator reliable?

Yes, a blackjack odds calculator is a precision tool that relies on probability algorithms and mathematical models to assess your hand and the dealer’s upcard. It will, then, recommend a statistically most profitable move for the given scenario.

Understanding blackjack odds is essential to ensuring you have a winning hand. Out of all card games, blackjack offers some of the most favorable odds, allowing players to change the outcome of the game to their favor. Today, we’ll break down the probabilities and payout structures in blackjack to help you make smarter decisions. You’ll learn how to identify favorable scenarios, lower the house edge, and possibly gain an advantage.

What Are Blackjack Odds

In a game of blackjack, odds determine the probability of various potential outcomes, including busting (exceeding 21), losing, or winning. Understanding these probabilities enables you to adjust the outcome of your hands by considering the likelihood of the most probable scenarios. The more you understand the odds of winning in blackjack based on the dealer’s upcard and the cards you’re dealt, the easier it is to predict how the round might end. On almost all best real money blackjack sites, dealers have around a 49% chance of winning. Players, on the other hand, have around a 42% chance of getting the winning cards. Here are the key concepts you’ll need to make smarter and more confident decisions at the table:

House edge: The house edge is typically capped at 0.5% if you calculate the blackjack odds with the perfect strategy. In other words, you lose about 50 cents on every $100 wager placed.
Blackjack probability (odds of getting 21): The odds of getting a natural blackjack (a 10 and an Ace) right from the get-go are around 4.8%. To put it in the right perspective, that’s 1 in 21 hands.
Dealer’s bust odds: The dealer’s upcard determines whether they bust or not. For example, the dealer is most likely to bust when they have a 4, 5, or 6. In such scenarios, the odds of going over 21 are at 42%.
Odds of busting: Your hand directly determines whether you win or lose. The higher the hand, the greater the bust odds. For example, if your hand counts as 12, you have around 31% chances of busting.

Odds of Winning in Blackjack

So, what are the odds of winning in blackjack? The outcome of the game depends on numerous factors, such as the dealer’s upcard, your blackjack strategy, and table rules. Since the dealer calls the last shot, the house has a built-in edge over the player. However, players can get closer to breaking even, thanks to pushes (the dealer and you tie) and 3:2 payouts for natural blackjack. The win percentages for different outcomes are listed below. These odds are calculated using a math technique known as combinatorial analysis. It helps players calculate the probability of breaking even, winning, or losing on a hand of blackjack across all possible scenarios.

Player wins: 42.43%
Dealer wins: 49.09%
Pushes (no win/loss): 8.48%

Note: If a hand ends in a push (no win/loss scenario), you can break even after your bet settles, giving you a slightly higher odds of winning in blackjack. If pushes aren’t in the game, you have 46.36% of scoring a winning hand. A natural blackjack pays extra (1.5x your initial bet), giving you an edge over the dealer and ensuring higher RTP. Though the chances of getting a blackjack are at 4.75%, these odds work in your favor, boosting your long-term probability of winning.

Player and Dealer Bust Probabilities

Whether you play in retail casinos or if you are using the best blackjack apps, the players always go first, which means the round can end before the dealer even gets his turn. If the players bust, that’s an automatic victory for the dealer, so let’s discuss what the odds are of that happening.

Player Bust Odds by Hand Total

The higher your hand total, the higher the odds of busting, especially if you decide to hit. That’s why a general rule of thumb is to stand (not ask for another card) on 17 or higher.

Player Hand Total	Odds of Busting	Comment
21	N/A	Automatic win with higher payout
20	92%	Player should stand
19	85%	Player should stand
18	77%	Player should stand
17	69%	Player should stand
16	62%	Player can stand or hit
15	58%	Player should hit
14	56%	Player should hit
13	39%	Player should hit
12	31%	Player should hit

Dealer Bust Odds by Upcard

The dealer’s upcard plays a critical role in determining the dealer’s bust odds. Cards like 9,10, or Ace significantly lower the odds of a bust, whereas 4, 5, and 6 increase them.

Dealer Upcard	Odds of Busting	Comment
2	35%	A dealier isn’t in a tough position
3	37%	The dealer is still in a good position
4	40%	The chance of busting or ending up with a weak hand is high
5	42%	High chance of house busting, players should stand
6	42%	High chance of house busting, players should stand
7	26%	Less likely to bust
8	24%	Dealer has a strong hand (pushing odds are 8%)
9	23%	Low bust potential and better odds for the dealer
10	23%	Minimal bust odds
Ace	17%	Dealer’s best card

Basic Strategy and Its Impact on Odds

A basic blackjack strategy refers to a blackjack odds chart that lets you plan your every move based on the realistic probability of winning. Put simply, you use a chart to determine when you should stand, split, hit, or double down. With a basic strategy, you avoid leaving anything to chance, lowering the house edge to around 0.5%. For example, if you end with a hard 16, your odds of busting are around 62.5%. According to the basic strategy, the best move would be to stand, but only if the dealer’s upcard is lower than 7. If their card is 7 or stronger, the best bet is to hit. You should also consider using a blackjack odds calculator to analyze blackjack hands and determine the best option based on the situation you find yourself in.

Hard 16 Blackjack Odds Chart

In blackjack, a hand counting as 16 (without an Ace as 11) is called a hard 16. The dealer must take another card (hit) if a player has a total of 16 or lower, or stand on hands valued at 17 or higher. The rules might vary as there are multiple variations of blackjack casino games. Still, the upcard has a strong impact on what is the best possible move for player.

Dealer Upcard	Best Move	Win %	Lose %	Push %
2	High bust odds, player should stand	35%	65%	8%
3	High bust odds, player should stand	37%	67%	8%
4	High bust odds, player should stand	42%	58%	8%
5	High bust odds, player should stand	42%	58%	8%
6	High bust odds, player should stand	42%	58%	8%
7	Strong dealer hand, player should hit	26%	74%	8%
8	Strong dealer hand, player should hit	24%	76%	8%
9	Hit or surrender (if allowed)	23%	77%	8%
10	Hit or surrender (if allowed)	23%	77%	8%
Ace	Hit or surrender (if allowed)	17%	83%	8%

Blackjack Side Bet Odds and House Advantage

Blackjack players can opt for a side bet when they are feeling lucky and want to take a shot at a higher payout. However, side wagers increase the house advantage, and professional players never take them.

Perfect Pairs

In the Perfect Pairs scenario, your side wager is only valid if you get a pair from the first two cards you’ve been dealt. The house edge ranges from 2% to 11%, depending on the specific rules and payout structure. Here are the blackjack side bet odds for different outcomes with Perfect Pairs:

Mixed Pair (two same-rank cards of different colors and suits, such as a black 10 and a red 10): 5:1 payout
Colored Pair (two cards of the same color but different suits, such as two red or black 10s): 12:1 payout
Perfect Pair (two identical cards of the same color, rank, and suit, like two red Queens): 25:1 payout

21+3

21+3 is a blackjack scenario where you form a so-called three-card poker hand using the dealer’s upcard and your first two cards. The house advantage for this side bet ranges from 3%-7%. Here are the expected payouts:

Flush: 5:1 payout
Straight: 10:1 payout
Three of a Kind: 30:1 payout
Straight Flush: 40:1 payout
Suited Trips: 100:1 payout

Insurance

In blackjack, players can rely on “insurance” to salvage up to half of their initial stake in a scenario where a dealer pulls out an Ace. If the dealer gets to 21 before you, you get 2:1 odds on your insurance wager to mitigate your losses. Again, pro players don’t recommend this move as it increases the house advantage (around 7%).

Bet the Set

If you get a pair from your first two cards, you can place this type of side bet. However, Bet the Set raises the house edge to +8%, so it’s mostly used when someone plays for fun. Here’s what you can expect:

Mixed pair: 10:1 payout
Suited pair: 20:1 payout
