Blackjack Odds of Winning
With perfect basic strategy at a 6-deck table, you win about 42.4% of hands, lose 49.1%, and push 8.5%. You lose more often than you win — yet the house edge is only ~0.6%, because your wins are bigger than your losses on average.
Blackjack's odds confuse people because two true statements sound contradictory: the dealer beats you more often than you beat the dealer, and blackjack is still the best bet on the casino floor. Both hold because the game isn't scored in hands — it's scored in dollars. Here is every probability that actually matters, and what each one means for how you play.
The headline numbers
| Outcome (per resolved hand) | Probability | What it means |
|---|---|---|
| You win | 42.4% | Includes 3:2 blackjack wins and won doubles |
| You lose | 49.1% | The dealer wins more hands than you. Always. |
| Push | 8.5% | Tie — your bet comes back |
| Win, excluding pushes | 46.3% | Of hands that get decided, you take 46.3% |
So how is the house edge only ~0.6%? Because basic strategy maximizes dollars, not win rate. Blackjacks pay 3:2 — a bonus the dealer never gets. And the book tells you to double and split exactly when the odds favor you, so your average win is worth more than your average loss. A strategy that chased win percentage instead — never doubling, never splitting, never busting — would win more hands and lose more money. Want the exact edge for your table's rules?

Odds of being dealt a blackjack
A natural — ace plus ten-value card off the deal — lands 4.75% of the time at 6 decks: about 1 in 21 hands. Single deck is slightly friendlier at 4.83%, one of the quiet reasons single-deck games only stay profitable for casinos by cutting the payout to 6:5. At roughly one natural every 21 hands, a 100-hand session should deal you four or five — and each one is where a big chunk of your 3:2 value lives.
Probability of busting on the next card
Every stiff hand is a number, not a feeling. This is the chance that one more card busts you:
| Your hard total | Bust chance if you hit |
|---|---|
| 12 | 31% |
| 13 | 39% |
| 14 | 46% |
| 15 | 54% |
| 16 | 62% |
| 17 | 69% |
| 18 | 77% |
| 19 | 85% |
| 20 | 92% |
Notice 12: it busts less than a third of the time, which is why the chart hits it against most up-cards. And 16 — the most hated hand in the game — survives a hit 38% of the time, which is more than it wins by standing against a strong dealer card. For the exact win/lose/push odds of any specific hand against any up-card, the new hand calculator computes them on the spot.
The dealer's bust odds — and why they bust second
The dealer busts 28.2% of all hands. By up-card it swings enormously: 43.9% showing a 6 down to 17% showing an ace — the full table is on the dealer bust odds page.
But here's the probability that explains the entire casino business: the chance you and the dealer bust on the same hand is effectively zero for you — because you act first. Bust, and your bet is gone before the dealer draws a card. The dealer's 28.2% bust rate only helps you when you're still standing. The order of play IS the house edge. Strip out the 3:2 bonus and the player's free choices, and that one asymmetry is what's left paying the casino's light bill.
Losing streaks are part of the price
Lose 49% of resolved hands and streaks are arithmetic, not bad luck: 8+ losses in a row shows up roughly once every couple hundred hands. If you play a few hours, you will probably see one. It isn't the shoe, the new player at third base, or a rigged shuffle — it's the expected texture of a near-coin-flip repeated hundreds of times. This is also exactly why betting systems fail: a Martingale that doubles after each loss meets an 8-loss streak needing 256 units on the next hand. The streaks aren't rare enough to outrun.
Frequently asked questions
What are the odds of winning a blackjack hand?
About 42.4% win, 49.1% lose, 8.5% push with perfect basic strategy at 6 decks — 46.3% of decided hands. The house edge stays near 0.6% because 3:2 blackjacks and well-timed doubles and splits make your average win bigger than your average loss.
What are the odds of being dealt a blackjack?
4.75% at 6 decks — about 1 in 21 hands. Single deck nudges up to 4.83%, since your ace removes a bigger share of the remaining aces, making the ten-card you need relatively more likely.
What is the probability of busting if I hit?
It scales with your total: 31% on hard 12, 54% on 15, 62% on 16, and 92% on 20. The dealer busts 28.2% of hands overall — from 43.9% against a 6 to 17% against an ace. The hand calculator gives exact figures for any hand.
Is an 8-hand losing streak a sign the game is rigged?
No — at a 49% loss rate per resolved hand, 8+ consecutive losses land roughly once every couple hundred hands. It's normal variance, and it's the rock that betting progressions break on.
