DE Insurance
In blackjack, insurance is an optional side bet offered when the dealer’s upcard is an Ace. You stake up to half of your original wager on the dealer having a ten-value hole card (10, J, Q, or K). If the dealer turns over a natural blackjack, the insurance bet pays 2:1; if not, the insurance chips are lost, and the main hand continues as normal.
How Blackjack Insurance Works
Insurance appears at a very specific moment in the hand. Knowing the order of actions helps beginners avoid confusion. Here is how this works at a classic blackjack table:
- You place your main bet.
- Cards are dealt: you get two cards, the dealer gets one face up and one face down.
- If the dealer’s upcard is an Ace, the dealer offers insurance to all players.
- You can either refuse or place an extra bet of up to half your original stake on the insurance line or button.
The dealer checks the hole card for blackjack:
- If the dealer has blackjack, the insurance bet wins 2:1, but you lose your original stake unless you also have blackjack (in which case the round ends with a push).
- If the dealer does not have blackjack, the insurance bet is lost, and the hand continues with your original cards.
Example Of An Insurance Bet
A concrete example makes the numbers clearer:
- Your main bet: $20
- Dealer’s upcard: Ace
- You take insurance: $10 (half of your main bet)
- Dealer has blackjack: You lose the $20 main bet. Your $10 insurance pays 2:1, so you win $20 profit (and get your $10 insurance stake back), resulting in no net change overall.
- Dealer does not have blackjack: You immediately lose the $10 insurance. You then play out your $20 main hand as normal and can still win, lose, or push.
This is why many beginners think of insurance as “protecting” their hand. Mathematically, though, the price of that protection is high.
Odds, Payouts, And Why Insurance Is A Bad Deal
On the surface, getting paid 2:1 looks fair, but the hidden problem is the actual chance that the dealer has a ten-value card under the Ace. In a typical multi-deck game, when the dealer shows an Ace, the chance the hole card is worth 10 is around 30–31%.
Because the payout doesn’t match the true odds, insurance carries a house edge of roughly 7–8% in common multi-deck games. For that reason, standard blackjack strategy for recreational players recommends declining insurance, even if it feels safer in the moment. Only advanced card counters, who track how many ten-value cards remain, can sometimes turn this bet into a positive play.
FAQs
Can I take insurance if I do not have blackjack?
Yes. Insurance is offered based on the dealer’s upcard, not on your total. You can take it whenever the dealer shows an Ace, whether your own hand is weak, strong, or you have a natural blackjack.
Is insurance offered in every blackjack game?
Many standard blackjack variations offer insurance. But some low house edge games or specialized games eliminate it entirely. You can check this on the table diagram or in the game’s help section.
