Casino Hold vs. House Edge: How Casinos Really Make Money

Most casino guides explain house edge and stop there. That leaves out the more important number. Casino hold — the percentage of the money you bring to the table that the casino actually keeps — is typically many times larger than the house edge, and understanding why is the difference between a player who budgets realistically and one who is repeatedly surprised.

Quick answer: House edge is the casino's expected profit per wager, usually 0.5% to 5%. Casino hold is the percentage of a player's total buy-in the casino keeps, often 15% to 25%. The gap exists because players wager the same money repeatedly, and the house edge applies to every wager, not to the buy-in.

House Edge: The Per-Bet Number

House edge measures expected loss per unit wagered. Bet $100 on a game with a 1.5% edge and your mathematically expected loss is $1.50 — on that single wager.

Typical figures across common games:

• Blackjack with basic strategy: roughly 0.5%
• Baccarat banker bet: roughly 1.06%
• Craps pass line with odds: under 1% on the combined wager
• European roulette: 2.7%
• American roulette: 5.26%
• Online slots: commonly 2% to 8%, depending on the title's RTP

These numbers are accurate and useful. They are also routinely misread as "I will lose 1.5% of my money," which is not what they say.

Hold: The Number That Actually Describes Your Session

Here is the mechanism. You buy in for $200 at a blackjack table with a 0.5% house edge. You bet $25 a hand and play sixty hands an hour. That is $1,500 wagered in an hour — not $200.

Apply 0.5% to $1,500 and your expected loss is $7.50. That sounds trivial until you recognize the variance around it. Over a three-hour session you have wagered $4,500 against a $200 buy-in, and the distribution of outcomes includes a substantial probability of losing the entire buy-in even though your expected loss is roughly $22.50.

Casino hold captures this reality. Industry hold percentages on table games commonly run 15 to 25 percent of drop — meaning for every $100 in chips players buy, the casino keeps $15 to $25. That figure reflects recycling: the same dollar gets wagered many times before it leaves the table.

Why the Gap Matters to Your Budget

If you budget using house edge, you will underestimate your likely session loss by roughly an order of magnitude. If you budget using hold, you get a realistic picture: assume you will lose a meaningful fraction of what you bring, and size your buy-in accordingly.

The practical rule is simple. Decide what you are comfortable losing entirely, bring that amount, and treat anything you leave with as a good outcome. This is not pessimism — it is the same arithmetic the casino uses to forecast its own revenue.

The Three Levers That Change Your Hold

Hold is not fixed. Three variables control it:

• Game choice. A 0.5% edge game and a 5% edge game produce a tenfold difference in expected loss per dollar wagered. This is the largest lever and the easiest to pull.
• Bet size relative to bankroll. Betting $25 a hand on a $200 buy-in produces far higher variance — and a far higher chance of total loss — than betting $5.
• Time at the table. Every additional hour multiplies total wagered. Session length is the variable most players never consciously choose.

Notice that only one of these has anything to do with skill. Game selection, bet sizing and session length are decisions you make before the cards come out. Our casino strategy section breaks down expected loss by game and betting pattern.

How Online Play Changes the Math

Online casino games run dramatically faster than live ones. A live blackjack table deals roughly 60 to 80 hands per hour. An online table with no other players can exceed 400. Online slots can spin 600 to 900 times an hour.

Speed multiplies total wagered, which multiplies expected loss even if the house edge is identical or slightly better online. A 4% RTP advantage on an online slot does not compensate for spinning ten times as fast. This is the single most important thing for players transitioning from land-based to online play to internalize.

The countermeasure is deliberate: use session limits, set loss limits before you start, and treat the speed as a reason to bet smaller rather than a reason to play longer. Licensed operators listed on our best online casinos page are required to provide these tools.

Where Bonuses Fit

A deposit bonus reduces effective house edge on the wagering it covers — genuinely, not theoretically. The catch is playthrough. A $100 bonus with 30x wagering requires $3,000 in bets, and the house edge applies to every dollar of it.

Whether a bonus is positive expected value depends entirely on the interaction between bonus size, playthrough multiple, and the house edge of eligible games. Our best casino bonuses page publishes the full terms, which is the only way to run that calculation honestly.

Frequently Asked Questions

What is the difference between house edge and hold?

House edge is expected loss per wager. Hold is the percentage of a player's total buy-in the casino keeps over a session, and it is much higher because money is wagered repeatedly.

What is a typical casino hold percentage?

Table game hold commonly runs 15 to 25 percent of the money players bring to the table, varying by game and by property.

Which casino games have the lowest house edge?

Blackjack with correct basic strategy, baccarat's banker bet, and craps pass line with full odds all sit at or below roughly 1 percent.

Does playing longer improve my chances?

No. Longer sessions increase total amount wagered, which increases expected loss. Time at the table works against the player in every negative-expectation game.

Do online games have a better house edge?

Often slightly, since overheads are lower. But online games run far faster, so total wagered per hour is much higher and expected loss per hour is typically greater.

Bottom Line

House edge tells you how the game is priced. Hold tells you what a session is likely to cost. Budget with the second number, choose low-edge games, control your bet size, and decide your session length before you start.
