Ever noticed how some decisions seem like a smart safety move but rarely turn out that way?
Many optional protection offers are designed to look helpful at first glance. Whenever people are presented with a quick choice that promises to “protect” their outcome, it can be tempting to accept it without thinking twice.
The issue?
Players rarely understand what insurance actually is, how the side bet works or when (if ever) it can be a good play. Here we cover everything you need to know about blackjack insurance so you can confidently decline every time.

Understanding Protection Choices
Insurance is a side bet offered when the dealer’s face up card is an Ace. Blackjack insurance essentially offers to “protect” your hand against the dealer having a natural blackjack.
Fair enough. Who doesn’t want to protect themselves?
Let’s back up though.
On the surface it’s easy to assume insurance is some wonderful safety net for players. Don’t forget – it’s called insurance. But the terminology takes a lot of the bitter sting out of the side bet being, well… another side bet.
Players who truly understand blackjack insurance don’t get fooled by the name. Instead they examine exactly how much it costs them in the long run.
How Optional Protection Offers Work
Step by step, insurance unfolds like this at the blackjack table:
- Dealer reveals an Ace as their face up card during the initial deal
- Players are given the option to buy insurance before the dealer checks their hole card
- Players may make a side bet up to half of their original wager
- Dealer flips over their hole card
- If the dealer has blackjack with a 10-value card as the hole card (10,J,Q,K) then insurance pays out 2:1
- Dealer does not have blackjack – insurance bet lost and hand proceeds as normal
Let’s use an example bet of £50. You would be offered insurance up to £25. If the dealer has blackjack the side bet pays at 2:1 so you would win £50. Congratulations. You’ve lost £50 on the hand but won £50 on insurance. Doesn’t matter that you lost – breaking even is good right?
Wait…
That’s only if the dealer has blackjack.
What if they don’t?
Why Some Protection Offers May Not Be Beneficial
There lies the rub, friends.
For insurance to become profitable for players, the dealer would need to show blackjack at least one-third of the time (33.33%). Otherwise the bet will net a loss over time.
In fact, even in single-deck games where cards are more favourable the dealer only actually has blackjack roughly 31.37% of the time. Still doesn’t sound too bad? Keep reading…
Despite only deviating by a couple percentage points from what would be a break-even bet – that small difference results in the insurance bet having a house edge of 5.8% against players.
Now let’s compare that with the blackjack game itself.
Playing with basic strategy, the house edge you face on the main game sits at around 0.5%. Insurance bets alone range from a 5.8% house edge up to over 7.5% depending on how many decks are played with. Up to 15x worse than playing blackjack alone.
And don’t even get us started on games using multiple decks. More decks means there are fewer 10-value cards in proportion to the whole shoe, bringing that already poor probability of winning the insurance bet even lower. In an 8 deck game the house edge on insurance can exceed 7.5%.
Why People Choose Certain Protection Options
Ok ok – we get it. Buying blackjack insurance is bad.
Except players don’t always take insurance because the math works in their favour. Sometimes people just make really dumb plays in blackjack (don’t worry, we’ve all been there).
Players tend to buy insurance in these common scenarios:
They Have A Good Hand: Holding a strong 19 or 20 can be intimidating. Nobody wants to lose that hand. Buying insurance feels like the responsible thing to do if the dealer has blackjack.
They Have A Bad Hand: Players stuck with a poor starting hand like 15 or 16 may take insurance as a consolation. If the dealer has blackjack at least they win something with insurance. Since those hands are likely to bust, taking insurance doesn’t hurt, right?
Bad Decision Making: Insurance is often a snap decision. The dealer flips an Ace and players have a split second to act. In those moments logic flies out the window and players make emotional decisions. “I want to protect my hand” sounds way better than thinking about the numbers.
But here’s the thing…
Making a good (or bad) starting hand doesn’t change the math against you when it comes to blackjack insurance.
How to Decide Whether an Offer Is Worth It
Hopefully by now you’ll be thinking “no way!” But as Casino.org tips you may want insurance when counting cards.
Players who keep a running count of the deck can accurately gauge how many high cards remain. When the true odds are in favour of the dealer having a blackjack due to an abundance of 10s remaining in the shoe, then insurance can become a favourable bet.
For everyone else seated at the table:
- Insurance will lose you money consistently in the long run
- Buying insurance drastically increases the house edge you face
- It does not “protect” you from losing your hand
Think of it like this – when you take insurance you’re essentially adding another bet with a 7%+ house edge to every hand where the dealer flips Ace. That equity evaporates quickly over a long session.
Basic strategy has been mathematically proven to provide the best possible play for any hand combination vs the dealer. If those experts don’t recommend insurance – why should you?
Why It’s Sometimes Better to Decline Certain Offers
Insurance is hands down one of the worst bets you can make at the blackjack table.
The payouts look too good. The name insurance makes it feel harmless. Neither of those facts change the reality of what blackjack insurance really is – a bet with a house edge between 5.8% and over 7.5%.
Hit the rewind button for a second:
- Blackjack insurance bets pay 2:1 if dealer has blackjack when showing an Ace
- Dealer only has blackjack less than one third of the time
- Insurance has a house edge up to 15x higher than blackjack itself
- Blackjack strategy never suggests taking insurance
- Card counters can theoretically take insurance when counting cards
Learn basic blackjack strategy first. Memorize it. Then memorize it some more. When you sit down at the table and that dreaded Ace comes rolling onto the deck – chances are the right play is to politely decline insurance.
