80% Guide to Taking Insurance in Blackjack
Blackjack insurance is one of the most misunderstood side bets at the table. It’s offered when the dealer shows an Ace, and it seems like a smart way to protect your hand from an automatic loss — but is it really?
In this guide, I’ll break down how insurance bets work in blackjack, what they pay, and whether they’re worth your money. You’ll see real examples of winning and losing insurance bets, learn the actual odds, and find out how insurance fits into your overall approach.
What Is Blackjack Insurance?
Insurance in blackjack is a side bet offered when the dealer’s upcard is an Ace. You can place it before seeing how you’ll play your hand. It protects you in case the dealer’s downcard gives them blackjack.
Blackjack house odds, depending on the situation, may have players feeling like insurance is necessary. Here’s how it works.
- You can usually bet half of your original wager.
- The insurance pays 2 to 1 if the dealer has blackjack.
- If the dealer doesn’t have blackjack, you lose the insurance bet, but continue playing your main hand.
How Do Insurance Bets Work?
Here’s a step by step outline how insurance bets work in blackjack.
| Step | Description |
|---|---|
| 1 | Your first two cards are dealt; the dealer shows an Ace. |
| 2 | You decide whether to place insurance (usually up to half your original bet). |
| 3 | Dealer checks their downcard. |
| 4 | If dealer has a 10-point card, dealer has blackjack → insurance bet wins at 2-1. |
| 5 | If dealer does not have blackjack, insurance bet loses; the hand plays out as normal. |
Some blackjack tables use rules where the dealer hits on a soft 17 — a hand like Ace–6 that totals either 7 or 17. This can have a subtle impact on how often the dealer ends up with blackjack or how aggressively the hand plays out after insurance is offered. If you’re not familiar with the rule, it’s worth reviewing what is a soft 17 in blackjack before deciding how to approach side bets like insurance.
Odds for the Insurance Bet
When the dealer shows an Ace, taking insurance might seem like a smart safety net, but the math tells a different story.
In a single-deck game, there’s only about a 30.8% chance that the dealer’s face-down card is a ten, which is needed for blackjack. That probability shifts in multi-deck games depending on what’s left in the shoe, but it rarely improves enough to justify the bet. Despite paying 2:1, the true odds aren’t in the player’s favor.
This creates a significant house edge of 7–10% on insurance wagers. For most players, that makes insurance a negative expected value (EV) proposition. Unless you’re card counting and know the deck is stacked with ten-value cards, taking insurance consistently will hurt your bankroll over time.
- Roughly 30.8% chance the dealer’s downcard is a 10 in a single-deck game.
- Probability shifts in multi-deck games depending on remaining cards.
- House edge is typically 7–10% on insurance bets.
- Payout is 2:1, but true odds are worse, which makes insurance a negative-EV play for most players.
Insurance in Blackjack Cost & Examples
How much does insurance cost in blackjack? Usually, you’re looking at half of your original bet but some casinos require an exact 50%, and others allow any amount up to that.
As far as how much blackjack insurance pays out, it’s 2:1. If you bet $10 on insurance and win, you receive $20 plus your original $10 back.
To showcase examples from both sides, let’s suppose you get dealt a hand (ex: 10+7=17), the dealer’s upcard is an ace, and they offer you insurance before the game proceeds.
Example: Winning an Insurance Bet
Original bet: $20
Insurance bet: $10 (half)
Dealer has blackjack → you win $20 from insurance.
You lose your $20 main bet, but break even overall.
Example: Losing an Insurance Bet
Original bet: $20
Insurance bet: $10
Dealer does not have blackjack → you lose the $10 insurance.
Hand plays out; main bet may still win or lose.
Is Insurance Ever Worth It in Blackjack?
Whether insurance bets are worth it depends on your personal blackjack strategy and how you’re playing at a table.
- No, not in standard games — the odds don’t justify the payout.
- Yes, if you’re card counting and know the deck is rich in 10-value cards.
- Some high-stakes players use it for emotional security, but that’s a psychological choice, not a strategic one.
Common Misconceptions About Blackjack Insurance
Insurance Doesn’t Protect Your Hand
As strange as it sounds, insurance won’t actually protect your hand or original bet. When the dealer shows an ace, players typically have the option to place a second wager, called an insurance bet, equal to up to half their initial bet. It pays 2:1 if the dealer’s hidden card is a ten-value card, giving them blackjack.
The crucial detail is that this wager has nothing to do with your cards. It’s simply a side bet on the dealer’s hidden card.
Consider a straightforward example. You’re holding 20, one of the strongest hands in blackjack. The dealer shows an ace, and you decide to take insurance. If the dealer reveals a 10 underneath, they have blackjack. Your original $10 bet still loses.
The important takeaway here is that your hand strength doesn’t influence the insurance decision. The probability of the dealer having a ten-value card remains the same.
Why It’s Called “Insurance” When It’s Really a Side Bet
The term insurance can be misleading, and intentionally so. It sounds cautious and protective, when in reality it’s just another wager.
Using the same scenario, you bet $10 and end up with 20. The dealer shows an ace and offers insurance. You set $5 aside in case the dealer has blackjack.
If they do, your $10 main bet loses, but the insurance bet returns $10. The two cancel out, leaving you at break-even. The side bet simply balanced the loss.
Some jurisdictions have even discussed whether casinos should use more accurate terminology, since the label can give players a false sense of security.
The Psychological Trap of Protecting Your Hand
Casinos use insurance to tap into your psychological bias. Getting insurance becomes tempting when you’re holding a strong hand like a 19, as your instinct would naturally be to protect it.
However, the math doesn’t change based on your card. It doesn’t matter whether you have 12 or 20. The chance of the dealer getting a 10-card under that ace is still the same.
Players who take insurance to “protect” a strong hand are reacting purely based on emotion.
Over time, those small side bets accumulate and can quietly chip away at your bankroll, shifting the advantage back to the house.
Summary – Should You Take Insurance in Blackjack?
Here’s the bottom line: insurance is almost never a good bet unless you’re counting cards or playing in favorable conditions. The payout (2:1) doesn’t match the odds of the dealer holding blackjack and you’ll lose more than you win over the long run.
The point of playing a game like blackjack is to take advantage of the mild edge you can get against the house – not give it further edge back. Most players are better off sticking to basic strategy for blackjack and avoiding side bets altogether.
