Baccarat chance calculator: exact odds, house edge and hourly cost

Set the number of decks, the banker commission and the tie payout in the tool above. It returns the exact probability and house edge of every main bet, then converts that into what a session will actually cost you.

Baccarat rules differ far more than the felt lets on: six decks or eight, 5% commission or 4%, no-commission tables where a banker 6 pays half, ties at 8:1 or at 9:1. Every one of those switches moves the house edge, sometimes by more than the whole gap between banker and player. This tool, part of our set of free player calculators, gives you the exact figure for whichever table you are looking at — and it runs light enough to use on mobile data while you check a lobby. The rules behind the numbers are explained in how to play baccarat.

What the calculator works out

Exact win probabilities for each deck count

The calculator runs through every possible card combination for a shoe of the size you choose, applies the fixed third-card rules to each one and weights them by how often they occur. What comes back is the exact probability of a banker win, a player win and a tie — nothing is simulated. Deck count matters because taking a card out changes what remains: with a single deck that shift is noticeable, with eight decks it is barely there.

House edge for any commission and tie payout

Edge is simply the expected loss per unit staked. For banker it is the win probability × net payout, less the loss probability: at 5% commission, 0.4586 × 0.95 − 0.4462 = −1.06%. Drop the commission to 4% and it becomes 0.4586 × 0.96 − 0.4462 = −0.60%. Take commission away entirely and the banker bet would favour the player by 1.24%, which is precisely why no-commission tables bolt on a rule like "banker 6 pays 1:2" — that single exception costs 1.46%. For the tie: 9.52% × 8 − 90.48% = −14.36% at 8:1, and −4.84% at 9:1.

Two things jump out of that table. Deck count hardly touches the banker and player bets — five hundredths of a point separates them — while the tie swings by more than a full point. And under standard commission, banker stays the cheapest bet at every deck count. Only a change in the rules changes that picture.

Reading the expected loss per hour

An edge is a percentage, but what leaves your account is money. The calculator multiplies three figures together: average stake × hands per hour × house edge. The product is your expected loss per hour — a long-run average that individual sessions swing wildly around.

Three lessons come out of it. First, pace counts as much as stake: a ₦25,000 bettor at a squeeze table pays less per hour than a ₦10,000 bettor on a speed table. Second, the tie is ruinous — that same ₦10,000 at 70 hands an hour costs ₦100,520 an hour at 8:1. Third, over any single session variance dwarfs expectation. The standard deviation on a banker bet is roughly 0.93 units per hand, so 70 hands at ₦10,000 carries a one-sigma swing of about ±₦78,000 around a ₦7,420 expected loss. You will never see the edge in one night; you will see it across fifty.

Working through the calculator, step by step

1. 1

   Read the table rules first

   Find the deck count, the commission rule and the tie payout in the game's info panel or printed on the felt. Watch for any 'banker 6 pays half' or 'super six' wording.

2. 2

   Enter those rules above

   Set the decks, the commission percentage (or the no-commission variant) and the tie payout. Probabilities and house edges update as you type.

3. 3

   Take the lowest-edge bet

   Banker, almost always. At no-commission tables where a banker 6 pays half, it is player instead. Never the tie.

4. 4

   Add your stake and your pace

   Use your genuine average bet and a realistic hands-per-hour count: roughly 40 at a squeeze table, 60–80 with a live dealer, 120 or more on speed and RNG baccarat.

5. 5

   Hold the hourly cost against your budget

   If the figure exceeds what you would happily pay for any other evening out, cut the stake or the pace before you play rather than afterwards.

What this calculator will not do

• It does not track the shoe. Cards leaving the shoe move the main-bet probabilities by an amount too small to act on, and no betting system or scoreboard pattern moves them at all — see our baccarat strategies guide.
• It covers the main bets, not the dozens of proprietary side bets. The common ones — pairs, Big/Small, Dragon Bonus, Dragon 7, Panda 8 — are tabulated with their edges in the strategy guide.
• It assumes the game is fair. Licensed operators have their RNG and live tables audited; unlicensed ones may not, and availability from Nigeria varies by operator. Our online casino reviews note which platforms publish their table rules and test certificates.
