Definition
Hold Percentage is the actual portion of the money exchanged for chips (the “drop”) that the casino keeps as profit at the end of a shift or period. It is a measure of a game’s operational efficiency, not just its mathematical edge.
In context
If players put a total of $10,000 into a Blackjack table’s drop box during a shift, and at the end of the night the casino has $2,000 more in that box than it started with (after accounting for chip tray changes), the “hold” is 20%.
Why it matters
Hold percentage is how casino managers judge the performance of a game or a pit. While the “house edge” on Blackjack might be 0.5%, the “hold” is usually 15-20%. This is because players often bet their winnings back multiple times until the house edge eventually grinds them down.

In detail
The distinction between “House Edge” and “Hold Percentage” is perhaps the most important concept in the business of gambling. Many players hear that a game has a “1% edge” and assume the casino will keep $1 of every $100 they bring to the table. This is a mistake. The house edge applies to every bet made, while the hold percentage applies to the initial buy-in.
Let’s look at the math from the casino’s chair. A player walks up to a Blackjack table with $100. They buy $100 worth of chips. That $100 goes into the “drop box.” The “Drop” is now $100. Over the next hour, the player bets $10 per hand. They play 60 hands. In total, they have wagered $600. This $600 is called the “Handle” or “Action.” If the house edge is 1%, the casino “expects” to win $6.00 ($600 x 0.01). At the end of the hour, the player has $94 left. They leave the table. The casino’s “Win” is $6. The Hold Percentage is calculated as: (Win / Drop) x 100. In this case: ($6 / $100) x 100 = 6%. Notice that even though the house edge was only 1%, the casino “held” 6% of the player’s starting money. If the player had stayed for three hours and wagered $1,800, the “expected win” would be $18, and the hold would be 18%. This is why casinos want you to play longer; the hold percentage naturally increases with time, even though the house edge stays the same.
For a Casino Shift Manager, hold percentage is a diagnostic tool. Every game has a “theoretical” or “standard” hold:
- Blackjack: Typically holds 12% to 18%.
- Baccarat: Typically holds 10% to 15%.
- Roulette: Typically holds 18% to 25%.
- Slots: Typically hold 5% to 12% (depending on denomination).
If I see a Blackjack pit holding 30%, I don’t just celebrate the profit. I look for the cause. It could be that the players were simply unlucky, or it could be that the dealers are playing exceptionally fast (more hands per hour = more house edge exposure = higher hold). Conversely, if a pit is holding only 5%, I need to know why. Are the dealers making payout errors? Is there a card counter at the table? Or was there a “whale” who got incredibly lucky and walked away with a massive win?
Hold percentage is also influenced by “Game Pace.” This is why casinos use automatic shufflers. By removing the 3-minute manual shuffle every 15 minutes, the casino can squeeze in 10-15 more hands per hour. Those extra hands don’t change the house edge, but they significantly increase the “Handle,” which in turn drives up the Hold Percentage.
Players can use this knowledge to their advantage by understanding “Volatility.” In games like Baccarat, where the house edge is very low and the bets are often large, the hold percentage can swing wildly. A single player betting $50,000 can “break the bank” for the day, resulting in a “negative hold” for the casino. Over a month, these swings usually even out to the statistical norm, but in the short term, hold is unpredictable.
One final reality: “Hold” is what the casino pays the bills with. When a casino reports its earnings, it doesn’t talk about house edge; it talks about “Win/Hold.” As a player, the way to keep the casino’s hold low is to limit your “Time on Device” or “Time at Table.” The longer you stay, the more certain it is that the hold percentage will climb toward 100% of your buy-in. The goal is to hit a “positive variance” (a lucky streak) and walk away before the hold math catches up to you.
