The situation where even money appears
You have just been dealt a blackjack. The dealer's upcard is an ace. Before anyone plays a hand, the dealer asks if you want even money. What they are really asking is whether you want to take the insurance side bet against your own blackjack.
The moment feels like a choice between a certain payout and a risky one. It is not. It is a choice between two different bets, one of which carries a materially worse expected loss than the other. Understanding which is which requires looking at what the dealer is offering.
What the insurance bet is
Insurance is a side bet offered only when the dealer shows an ace. You place a separate wager, equal to half your original bet, that the dealer's hole card is a ten-value card. If the dealer has a ten underneath, the dealer has a blackjack and the insurance bet pays. If the dealer does not have a ten underneath, the insurance bet loses.
Even money is not a separate rule. It is a shorthand for taking insurance when you hold a blackjack. Instead of placing the insurance bet separately and waiting to see the dealer's hole card, the dealer offers to settle your hand immediately at a payout equal to your original wager. The arithmetic is identical to taking insurance and then having the dealer reveal a blackjack.
Why the payout looks attractive
A blackjack normally pays at a rate higher than an ordinary winning hand. When the dealer also has a blackjack, the hands push, and you receive your original wager back with no profit. Taking even money guarantees that you receive a profit on the hand instead of a push.
That guarantee is the trap. The word "guarantee" describes what happens on this one hand, not what happens over many hands. The insurance bet that even money represents has its own house edge, and it is one of the worst bets on the table. Every time you take even money, you are placing a side bet with a built-in expected loss.
The arithmetic without invented numbers
The exact house edge on insurance depends on how many ten-value cards remain in the deck or shoe at the moment the bet is offered. In a fresh single deck, the proportion of ten-value cards is known from the deck's composition: sixteen ten-value cards out of fifty-two. That proportion is the basis for the insurance payout being set where it is.
The key relationship is this: the insurance bet pays at a rate that is lower than the true odds of the dealer having a ten in the hole. When a bet pays less than the true odds of winning, the house holds an edge on that bet. That edge applies whether you take insurance on an ordinary hand or take even money on a blackjack. The two are the same wager.
No number printed here will tell you the exact edge on your table, because the edge shifts as cards leave the shoe. What does not shift is the direction of the edge: it stays with the house on every insurance bet, including every even-money settlement.
What changes under your control
You control whether you take the side bet. You do not control whether the dealer has a ten underneath, and you do not control the payout rate on the insurance wager. The decision is binary: accept the immediate settlement, or decline and play the hand normally.
When you decline even money, two outcomes remain. If the dealer does not have blackjack, your blackjack pays at its normal rate and you profit more than you would have under even money. If the dealer has blackjack, the hand pushes and you receive your original wager back with no profit. Over many repetitions of this situation, declining even money produces a better expected result than taking it, because you never place the high-edge insurance bet.
| Decision | What you are betting | Outcome if dealer has blackjack | Outcome if dealer does not have blackjack | Expected result over many hands |
|---|---|---|---|---|
| Take even money | Insurance side bet plus your original wager | You profit at the even-money rate | You profit at the even-money rate | Worse, because the insurance bet carries a house edge |
| Decline even money | Your original wager only | Hand pushes, no profit | Blackjack pays at its normal higher rate | Better, because no side bet with a house edge is placed |
Why the dealer offers it at all
The dealer offers even money because the house profits from insurance bets in the long run. The offer is not a favour, a courtesy, or a protection against the dealer's blackjack. It is an invitation to place an additional wager with a built-in edge for the house.
Casinos do not need you to take insurance on every hand. They need enough players to take it often enough that the aggregate of those side bets produces revenue. Even money is simply the version of that side bet offered to players who already hold the best possible hand.
Procedural mistakes around even money
The first mistake is treating even money as a refund or a protection. It is neither. It is a new bet with its own expected loss. The second mistake is taking even money because you are afraid of the push. A push returns your original wager; it does not cost you anything beyond the profit you would have made if the dealer lacked blackjack. The third mistake is assuming that a player who counts cards or follows a published strategy chart should take even money under some conditions. Strategy charts for blackjack derive from the exact rule set in use, including deck count and payout rates, and they treat insurance as a separate decision from the main hand. A chart that says to take insurance in a specific count situation is telling you to place that side bet because the remaining deck composition has shifted the edge, not because even money is a good default.
What the strategy chart tells you
Published basic-strategy charts assume you are not counting cards. Under that assumption, the correct play is to decline insurance and decline even money. The chart derives from the specific rule set in use: how many decks are in the shoe, when the dealer stands, whether doubling after splitting is allowed, and what a blackjack pays. Change any of those rules and the chart changes.
If you play with a strategy chart, read the insurance line carefully. Most charts list insurance as a separate row or column. The entry will tell you whether to take the side bet under the conditions the chart assumes. If the chart assumes no card counting, the entry will say to decline. If the chart is a count-based deviation chart, it will specify the count threshold at which the remaining deck composition makes insurance a break-even or better proposition. That threshold is a number you must read from the chart for your exact rule set; it is not a number that can be stated here as a universal.
The decision in one sentence
Unless you are counting cards and have a chart that tells you otherwise for your exact table rules, decline even money every time, because the side bet it represents carries a house edge and the push you are avoiding costs you nothing.
FAQ
Is even money the same as insurance?
Yes. Even money is the dealer's shorthand for settling your blackjack as if you had taken insurance and the dealer had a blackjack. The wager, the payout arithmetic, and the house edge are identical. The only difference is that the dealer handles the settlement immediately instead of waiting for the hole card to be revealed.
Does taking even money change the house edge on my blackjack?
It does not change the edge on the original blackjack wager. That bet is already settled favourably for you. What changes is that you have added a second wager, the insurance bet, which carries its own house edge. Your total expected result across both wagers is worse when you take even money than when you decline it.
When would a strategy chart ever say to take even money?
A count-based chart may say to take insurance when the remaining deck is rich enough in ten-value cards that the side bet becomes break-even or positive for the player. That threshold depends on the number of decks and the exact counting system the chart assumes. A basic-strategy chart that assumes no counting will list insurance as a bet to decline, and even money as a settlement to refuse.
