Hold Percentage

What Is Hold Percentage?

Hold percentage is the portion of all money wagered that a casino — or a specific game — keeps as revenue over a set period of time. If gamblers collectively bet $1,000,000 on blackjack tables in a month and the casino ends up keeping $110,000, the hold percentage for that period is 11%.

You'll also hear this called the hold, win percentage, or casino win rate. It shows up in casino financial reports, regulatory filings, and gaming industry analyses. For players, it's a window into the real-world cost of gambling — not just the theoretical cost.

How Hold Percentage Differs from House Edge

This is where things get genuinely useful to understand. House edge is the mathematical advantage built into a game's rules — a fixed percentage calculated on every individual bet. Hold percentage, on the other hand, is a real-world measurement of actual money retained over time.

They're related, but they are not the same number, and here's why: recycling. When a player wins money, they often bet it again. Each time money gets wagered, the house edge takes another bite. So even if the house edge on a slot machine is 8%, the hold percentage can climb to 25% or higher — because players are repeatedly cycling their chips and credits back into action.

Think of it like a toll road. The house edge is the toll rate per trip. The hold percentage is how much you've paid in tolls by the time you leave the highway for good.

A Concrete Example

Imagine a roulette wheel with a house edge of 5.26% (standard American roulette). A group of players sits down with a combined $500 in chips.

• Round 1: They bet the full $500. The house edge takes about $26.30 theoretically. Players are left with roughly $473.70.
• Round 2: They bet most of those winnings again — say $400. The house takes another ~$21.
• This continues until the session ends.

By the time the group cashes out, the casino may have retained $100–$150 of that original $500 — a hold of 20–30% — even though the house edge never changed from 5.26%. The act of re-wagering is what drives the gap between the two numbers.

Slot machines show this effect most dramatically. A machine might have a return to player (RTP) of 92% (meaning an 8% house edge), but casinos commonly report slot hold percentages of 20–30% because players feed winnings straight back in.

Why Hold Percentage Matters to You as a Player

Hold percentage won't tell you what will happen on any single visit, but it reveals something honest about the long-run flow of money. The higher the hold, the more a player population is losing relative to what they brought in.

If you're comparing games or venues, knowing the hold percentage gives you a clearer picture of actual outcomes — not just theoretical ones. Games with low house edges can still carry high hold percentages if the pace of play is fast or players tend to re-bet aggressively.

The takeaway: your effective losses depend on both the house edge and how many times you cycle your money through the game. Even a low-edge game gets expensive if you play long enough or fast enough.
