Baccarat: The Math of Banker vs Player

Why the banker bet wins more often, why it pays a commission, and the exact house edges for banker, player and tie from a full 8-deck calculation.

RTP Data Editorial · · 2 min read

Baccarat (in its common casino form, punto banco) offers three main bets: banker, player and tie. The player makes no decisions: fixed drawing rules decide everything. That makes baccarat a pure probability problem, and one we can solve exactly. We enumerated every possible sequence of cards from an 8-deck shoe. Here are the results.

How a hand works

The exact probabilities

Outcome Probability
Banker wins 45.86%
Player wins 44.62%
Tie 9.52%

Our own exact calculation, enumerating every card sequence from a full 8-deck shoe with the standard punto banco drawing rules. The results match the figures commonly published for this game.

The banker wins more often because its drawing rules let it act after seeing whether the player drew a third card, and what that card was.

Why the banker pays a commission

If the banker bet paid even money, it would favour the player. So casinos usually take a 5% commission on banker wins. With the commission:

Bet Payout House edge
Banker 1 to 1, minus 5% commission 1.06%
Player 1 to 1 1.24%
Tie 8 to 1 14.36%

Worked example: How the banker edge is calculated. Ties are a push for banker bets. The expected result per unit is 0.4586 × 0.95 − 0.4462 × 1 = −0.0106, an edge of 1.06%. For the player bet it is 0.4462 − 0.4586 = −0.0124, an edge of 1.24%.

The tie bet

A tie happens about 9.5% of the time. A fair payout would be roughly 9.5 to 1; paying 8 to 1 gives the house an edge of 14.36%, more than ten times the banker bet. Some tables pay 9 to 1, which lowers the edge but still leaves it far above the main bets.

Key point: Patterns on baccarat scoreboards ("the banker is on a streak") are a classic illusion. Hands from a shuffled shoe are almost independent, and no visible pattern changes the edges above.

Variations to check

Watch out: Even the best bet in baccarat loses about 1 unit in every 94 staked over the long run. Expected loss is always the total amount bet times the house edge.
