Blackjack pays 3:2
“Blackjack pays 3:2” means that a natural blackjack, an ace plus a ten-value card as the first two cards, wins one and a half times the stake, so a €10 bet returns €15 profit plus the original €10. It is the traditional payout for that hand, printed on the felt or in the game rules, and it sits apart from ordinary wins, which pay even money. When a table pays less for a natural, usually 6:5, the house edge rises sharply even though nothing else about the game looks different.
How the 3:2 payout is calculated
The ratio reads as profit to stake: for every €2 wagered on a hand that turns out to be a natural, the player wins €3. Put another way, the profit is the bet multiplied by one and a half, and the stake itself is handed back on top of it.
A €20 natural therefore pays €30 profit, and the player walks away from that hand with €50 in front of them. A €5 natural pays €7.50, which is why land-based tables keep half-value chips to hand.
The payout applies only to a two-card 21 dealt at the start of the hand. Three or more cards that add up to 21 are a strong total but not a blackjack, and they are paid at even money like any other winning hand. A natural made after splitting aces is usually treated the same way and paid 1:1, although that rule is set by each game’s published terms and varies between operators and studios.
If the dealer also has a natural, the two hands push and the stake is returned.
Where players meet the 3:2 rule
On a physical table the payout is usually printed across the felt, often in the line “Blackjack pays 3 to 2”, alongside the dealer’s rule on soft 17 and the insurance payout. Online, in RNG blackjack and live casino tables alike, it sits in the game’s rules or help screen rather than on the screen itself.
What we check first, before reading anything else in those rules, is the payout line for a natural.
It matters more than most of the details around it. Published rule-variation tables, including the widely cited Wizard of Odds figures, put the cost of moving from 3:2 to 6:5 at roughly 1.39 percentage points of house edge on a six-deck game, with all other rules held equal. A standard multi-deck game played with basic strategy sits at around 0.5%, so the switch takes it to roughly 1.9%, close to four times the cost. Because a natural turns up in roughly one hand in twenty-one, the difference is spread thinly across many rounds, which is precisely why players fail to notice it during a single session. The exact edge for any one table depends on deck count, soft-17 rules and doubling options, so these figures describe a benchmark game rather than every table on offer.
What 3:2 is confused with
The most frequent confusion is with 6:5, which looks close on the felt but pays a €10 natural just €12 rather than €15. Some tables advertise single-deck play or other attractive rules next to a 6:5 payout; published calculations show that a single-deck 6:5 game still carries a higher edge than an eight-deck game paying 3:2.
Even money and insurance
Even money is the offer a dealer makes when the player holds a natural and the dealer shows an ace: take 1:1 now instead of waiting to see the hole card. At a 3:2 table it produces the same result as insuring the hand for half the stake, and the long-run value of declining is higher, because the full 3:2 is paid whenever the dealer misses. Insurance itself is a separate side bet paying 2:1, and it should not be read as part of the blackjack payout.
Finally, 3:2 is not the odds of being dealt blackjack, and it says nothing about how often a natural appears.
