You've probably stood on a plush, windowless gaming floor at 2:00 AM, heard the rhythmic ching-ching-ching of a slot machine, and wondered how much cash is actually flowing into the building. It feels like an infinite fountain of money. But the reality is a bit more complicated than just "the house always wins."
Honestly, the answer to how much does a casino make in a year depends entirely on whether we’re talking about a massive Vegas monolith or a small "local" spot in the Midwest.
In 2024, the U.S. commercial gaming industry hit a staggering $71.92 billion in revenue. That was a record. Again. It’s the fourth year in a row that the industry has smashed its own ceiling. If you add in tribal gaming, which pulled in about $43.9 billion in fiscal year 2024, the total U.S. gambling pie is well over $115 billion.
But that's the macro view. Let's get into the weeds of the individual properties.
The "Average" Big Strip Casino: A $317 Million Beast
If you’re looking for a benchmark, the University of Nevada, Las Vegas (UNLV) Center for Gaming Research provides some of the best data on the planet. Their 2024 report on the "Average Big Strip Casino"—specifically properties on the Las Vegas Strip earning over $72 million a year—paints a wild picture.
On average, one of these big boys generates roughly $317.3 million in gaming revenue annually.

That breaks down to about $867,003 every single day.
Wait, it gets better. That $317 million is just from the gambling. When you add in the "non-gaming" revenue—the $271-a-night rooms, the $150 steaks, and the overpriced cocktails—the total revenue for a single large resort can easily double. In fact, for many Strip giants, gaming only accounts for about 40% of their total income. They’re basically giant hotels with a casino attached as a side hustle.
Where the Money Actually Comes From
It’s not the high-stakes poker games you see in movies.
- Slots are the undisputed kings. In a typical big Strip casino, slots bring in roughly $181 million a year. That’s 57% of the total gaming win.
- Table games (the "pit") account for about $126.9 million.
- Sportsbooks and Poker are surprisingly small fish, often making up less than 2% or 3% of the total revenue.
Tribal vs. Commercial: The Quiet Giants
People often forget about tribal gaming. That’s a mistake. The National Indian Gaming Commission (NIGC) reported that tribal operations hit a record $43.9 billion in 2024.
While there are over 500 tribal gaming operations, the wealth is concentrated. About 9% of tribal facilities generate more than $250 million annually. These are the mega-resorts that rival anything in Vegas. On the flip side, over half of tribal casinos make less than $25 million a year. They’re smaller, community-focused hubs.
Regional commercial casinos—like the ones in Pennsylvania or Maryland—are also absolute units. For example, MGM National Harbor in Maryland and Encore Boston Harbor in Massachusetts consistently rank as top earners outside of Nevada. In August 2025 alone, Pennsylvania casinos generated over $582 million in combined revenue.
The Profit Margin Problem
Making $300 million sounds great. But how much does the owner actually pocket?
Operating a casino is insanely expensive. You’ve got thousands of employees, massive electricity bills (those lights aren't cheap), and, most importantly, taxes.
In some states, the tax rate on gambling revenue is brutal. Pennsylvania, for instance, taxes slot machine revenue at around 54%. Think about that. For every dollar a machine "wins," the state takes more than half before the casino pays for the machine, the staff, or the free soda.
In Nevada, the tax rate is much lower—maxing out at about 6.75%—which is why the Strip can afford such ridiculous luxury.
Profit margins for well-run casinos usually hover between 15% and 25% (often measured as EBITDA). If a casino brings in $100 million in revenue, they might only walk away with $20 million in actual profit after everyone else is paid.
Why the Numbers are Shifting
The 2024 and 2025 data show a clear trend: the "floor" is changing.

- iGaming is exploding. Online casinos (iGaming) generated $8.41 billion in 2024 across just seven states. That’s nearly a 29% jump.
- Sports betting is everywhere. Revenue reached $13.78 billion in 2024. While it has lower margins than slots, it brings in a younger crowd.
- The "Mass Market" Shift. In places like Macau (which hit $30.9 billion in 2025), operators are moving away from "VIP" high-rollers and toward "premium mass" players. It’s more stable.
Summary: What Does This Mean for You?
If you’re thinking about the business of gambling, the takeaway is that the "house" has to work a lot harder than it looks. They aren't just sitting back and watching the money roll in; they are managing massive hospitality businesses where gambling is the engine, but not the whole car.
If you’re researching this for investment or business purposes, keep your eyes on the WPUPD (Win Per Unit Per Day). A healthy casino should see its slot machines "winning" at least $300 a day per unit. Anything less, and the floor space might be better used for a Starbucks.
Next Steps for Tracking Casino Performance:
- Check the American Gaming Association (AGA) quarterly "Gaming Revenue Tracker" for the most recent state-by-state breakdowns.
- Look at UNLV’s Center for Gaming Research for the most granular data on "hold percentages" and departmental expenses.
- Monitor quarterly earnings calls for public companies like MGM Resorts (MGM) or Caesars Entertainment (CZR) to see how non-gaming revenue (rooms/food) is pacing against the casino floor.
