What are Blackjack Odds?  

When it comes to Blackjack, there are two different types of odds to discuss. One references the potential winnings for various outcomes, while the other looks at the probability of a successful hand. Let’s take a look at both!  

Blackjack Payout Odds  

Without including side bets, there are two main payout odds in blackjack for players to consider. These are, of course, the potential winnings for a blackjack, which comes with odds of 3/2, or beating the dealer, which has associated odds of 1:1. While these apply to most games, some blackjack variations will offer different odds, so double-checking first is key!  

Blackjack Probability  

Alternatively, the odds of winning in blackjack are roughly 42.22%. These decrease to just 4.83% when looking at the blackjack probability of being dealt an Ace and a 10. 

How are Blackjack Odds Calculated?  

First things first, how exactly are blackjack odds calculated? It’s not as complicated as it might seem. The odds of blackjack are based on the probability of drawing certain cards from the deck. For instance, with a standard 52-card deck, the odds of drawing an Ace are 4 in 52 or roughly 7.7%.  

Blackjack odds can change based on the cards dealt and the choices you make during the game. So, the odds of winning blackjack aren’t set in stone – they’re fluid and can change as the game progresses.  

How Does House Edge Come into Play?  

All casino games come with a house edge and it’s important that these figures are known by players before committing to a wager.  

Understanding the Concept of House Edge  

So, what exactly is the house edge? Basically, it’s the advantage that the casino has over you in any given game. The house edge is designed to ensure the odds are always slightly in the casino’s favour. For every game you play, the casino has calculated the odds to give themselves a slight advantage. So, the house edge is essentially the odds of the casino winning against the odds of you winning.  

It’s worth mentioning that not all sessions will closely match the house edge, as this figure is calculated over hundreds of thousands, if not millions, of plays. Throughout a shorter session, larger swings in either direction are not unlikely.  

What is the House Edge in Blackjack?  

The house edge in blackjack, if following basic strategy, sits at 0.50%. This house edge comes from the fact that the player has to act first. If you go over 21, you lose, regardless of what the dealer’s hand is.  

Average Bust Rate Based on First Dealer up Card  

The dealer’s up card is the one shown to all players at the start of the round. While the cards that each player has is important, evaluating the dealer’s face up card can help players to make optimal decisions.   

For example, if the dealer has a high probability of busting, players may consider standing on a 12, as hitting could lead to a bust. Here’s a table that looks at the odds of winning blackjack, based on the dealer’s up card:  

Dealer’s Face up Card	Chance of Busting From Hitting
A	11.65%
2	35.30%
3	37.56%
4	40.28%
5	42.89%
6	42.08%
7	25.99%
8	23.86%
9	23.34%
10, J, Q, K	21.43%

The Average Bust Rate Based on a Player’s Hand in Blackjack  

Perhaps even more crucial than the dealer’s face up card are the ones dealt to each player. Here is the average bust rate of each hand, based on what the player is holding:  

Player’s Hand Total	Chance of Busting From Hitting
11 or less	0%
12	31%
13	39%
14	56%
15	58%
16	62%
17	69%
18	77%
19	85%
20	92%
21	100%

Does Blackjack Have Good Odds?  

When compared to other casino games, either online or at a land-based alternative, blackjack has one of the lowest house edges. The same can be said for different variations, such as Lightning Blackjack.  

As mentioned earlier, the house edge in blackjack can sit at 0.50% or lower, with the Blackjack best odds being 0.28% in favour of the house. The average of other casino games, however, are:  

• Baccarat – 1.06%  
• Craps – 1.36%  
• European Roulette – 2.70%  
• American Roulette – 5.26%  
• Online Slots – 2-5%   
• Physical Slot Machines – 10-20%  

Keep in mind that with casino card games, the betting options influence the house edge. For example, betting on the ‘Banker’ in Baccarat has the aforementioned 1.06% house edge, while betting on the player has a house edge of 1.24%.   

What are the Odds of Winning Blackjack?  

The actual odds of winning Blackjack depend on the strategy being used. For those that have seen the basic strategy blackjack odds table, this can give players an indication of the best possible move, based on probability. If played according to this blackjack odds table, the probability of winning is roughly:  

• Player Win – 42.22%  
• Dealer Win – 49.10%  
• Draw or ‘Push’ – 8.48%  

Again, these percentages are rough estimations, but can vary depending on the type of Blackjack game played and the house rules of the casino. Always take this into consideration before betting. 

Odds of Blackjack Side Bets  

Side bets can add an extra layer of excitement to the game. However, they typically come with a higher house edge on average. With that being said, here are the odds of Blackjack side bets:  

• Insurance – 2:1  
• Perfect Pairs – Up to 25:1  
• 21 + 3 – Up to 100:1  
• Royal Match – Up to 25:1  
• Super Sevens – Up to 5,000:1  

Conclusion  

That wraps up this article on blackjack odds. Understanding the ins and outs of the game can greatly help players to increase their chances while at the blackjack table. Furthermore, players could consider learning basic strategy in order to make optimal decisions, which can reduce the house edge to around 0.50%, if done correctly!
