6:5 Blackjack Payouts: How to Calculate Winnings and Spot the Rule

A natural blackjack is one of the most exciting hands in the game: an Ace plus any 10-value card on the first two cards dealt. Before celebrating, however, it pays to check the blackjack payout posted at the table. A 6:5 blackjack table pays six units of profit for every five units wagered on a natural blackjack, while the traditional rule pays 3:2.

The math is simple, but the difference can be meaningful. On a $25 blackjack wager, a 6:5 table pays $30 in winnings. A 3:2 table pays $37.50 in winnings for the same hand. That is a $7.50 difference from just one natural blackjack.

Understanding the payout lets players make informed table choices, calculate their winnings quickly, and recognize why experienced blackjack players often seek out games that pay 3:2. For dealers and anyone learning table-game procedures, mastering the 6:5 calculation also makes payouts faster and more accurate.

What Does 6:5 Mean in Blackjack?

The phrase 6:5 describes the profit paid when a player receives a natural blackjack. For every five units wagered, the player wins six units.

For example:

• A $5 blackjack pays $6 in winnings.
• A $25 blackjack pays $30 in winnings.
• A $100 blackjack pays $120 in winnings.

The player also keeps the original wager when the hand is paid normally. So, if a player wagers $25 and receives a blackjack at a 6:5 table, the profit is $30 and the player receives $55 back in total: the original $25 wager plus the $30 winning amount.

This rule applies specifically to a natural blackjack. A hand that reaches 21 with three or more cards, such as 7, 7, and 7, is normally paid at even money if it wins. It is not a 6:5 blackjack payout.

6:5 Blackjack Formula

To calculate the winning portion of a 6:5 blackjack payout, use this formula:

Blackjack winnings = wager × 6 ÷ 5

Or, expressed as a decimal:

Blackjack winnings = wager × 1.20

To find the full amount returned to the player, including the original wager, use:

Total returned = wager + blackjack winnings

Because 6:5 equals 1.2 to 1, the player wins 120% of the original wager. This is also easy to remember as even money plus one-fifth of the bet.

Quick Method: Pay Even Money Plus One-Fifth

A practical way to calculate a 6:5 payoff is to begin with even money, then add 20% of the wager:

1. Pay the wager amount as even money.
2. Calculate one-fifth of the wager.
3. Add that one-fifth bonus to the even-money payout.

For a $45 blackjack:

• Even-money winnings: $45
• One-fifth of $45: $9
• 6:5 blackjack winnings: $54

The player would receive $99 in total when the original $45 wager is returned along with the $54 profit.
