Casino economics is measured with a small set of practical numbers: house edge, theoretical win, actual win, hold percentage, coin-in, drop, average bet, time played, reinvestment rate, labor cost, and floor yield. This quick reference explains what each number means and how casino managers use it without confusing math with guaranteed results.
Quick Facts
- House edge is the game price; theoretical win is the expected result from actual play.
- Actual win can swing above or below theoretical win because gambling is volatile.
- Slot hold and table hold are not calculated the same way.
- Comps are usually based on theoretical value, not tonight’s actual result.
- Floor yield helps management compare games, machines, and space.
- Promotions should be judged by incremental value, not redemption alone.
- Public data from sources such as the American Gaming Association State of the States, the Nevada Gaming Control Board revenue reports, and the UNLV Center for Gaming Research can help readers see how gaming revenue is reported at industry level.
Plain Talk
This page is the pocket version of casino economics.
Use it when you need a clean definition, a formula, or a manager-side explanation. It is not a full finance manual. It is a casino-floor reference for the terms that drive table games, slots, comps, marketing, and player value.
The biggest mistake is treating one metric as the whole truth. House edge is not session cost. Actual win is not player value. Coin-in is not profit. Comps are not free. Hold is not always comparable across games. A busy game is not automatically a profitable game.

How It Works
Casino managers use economics as a dashboard, not a fortune teller.
| Metric | Formula | What It Tells Management | Common Mistake |
|---|---|---|---|
| Theoretical Win | Average Bet × Decisions Per Hour × Hours × House Edge | Expected casino value from play | Treating it as guaranteed win |
| Expected Loss | Total Amount Wagered × House Edge | Player-side expected cost | Looking only at buy-in |
| Coin-In | Bet Size × Number of Plays | Slot wagering volume | Calling it casino profit |
| Slot Hold % | Casino Win / Coin-In | Slot margin over coin-in | Comparing it directly to table hold |
| Table Hold % | Table Win / Drop | Table win against buy-in/drop | Treating it as house edge |
| Comp Value | Theoretical Loss × Reinvestment Rate | Offer value based on expected play | Thinking comps are gifts |
| Labor Cost Per Hour | Staff Count × Average Hourly Cost | Direct staffing cost | Ignoring supervision and relief coverage |
| Floor Yield | Casino Win / Floor Space | Productivity of space | Keeping games because they look busy |
The reference logic is simple:
- Measure action — average bet, coin-in, drop, time, decisions.
- Estimate value — theoretical win or theoretical loss.
- Compare actual result — actual win may be lucky or unlucky.
- Subtract cost — labor, comps, promotion, technology, tax, occupancy.
- Adjust decisions — limits, layout, offers, staffing, game mix.
Back of House Example
A slot bank looks busy, but its win per square foot is weak. A nearby bank has less visible traffic but stronger coin-in and hold. The slot manager does not judge only by noise or chair occupancy. The manager checks performance over time, player type, denomination, jackpot behavior, maintenance, offer response, and whether the bank supports a broader floor strategy.
On the table side, a blackjack table may look productive because it is full. But if the table has a low minimum, slow decisions, high labor coverage, and weak average bet, another table with fewer players may produce better economics.
That is why a casino quick reference needs formulas and judgment.
From the Casino Side:
Casino-side economics is about decision quality.
A manager does not need every number every minute. But the manager must know which number answers which question. If the question is player value, use theoretical loss. If the question is slot volume, use coin-in. If the question is table productivity, look at drop, win, hold, average bet, decisions, and labor. If the question is marketing, compare incremental theoretical value against offer cost.
Bad managers use numbers as decoration. Good managers use numbers to ask better questions.
The finance team wants accurate revenue. Table games wants controlled decisions. Slots wants machine productivity. Marketing wants profitable response. Hosts want reinvestment discipline. Compliance wants reporting integrity. Responsible gambling policy matters when the numbers encourage excessive play, credit stress, or loss chasing; resources such as the NCPG responsible gambling resources are important when economics touches harm risk.
Common Mistakes
- Calling table hold the same thing as house edge.
- Calling coin-in the same thing as casino win.
- Judging a player only by actual loss.
- Raising comps because a player lost big once.
- Keeping a game because it looks busy without checking yield.
- Measuring promotions by redemption instead of incremental value.
- Ignoring cost when discussing revenue.
Hard Truth
Casino numbers are useful only when they are attached to the right question. The wrong metric can make a bad decision look smart.
FAQ
What is the most important casino economics formula?
Theoretical Win is the core formula for player value on many live games: Average Bet × Decisions Per Hour × Hours Played × House Edge.
Is theoretical win the same as actual win?
No. Theoretical win is expected value. Actual win is what happened. A casino can lose actual money to a strong player session while still recording high theoretical value.
Is table hold the same as house edge?
No. Table hold compares table win to drop. House edge is the mathematical price of the game per wagered unit. They answer different questions.
Is coin-in the same as slot revenue?
No. Coin-in is total slot wagering volume. Slot win is the amount the casino keeps after payouts.
Why do comps use theoretical loss?
Theoretical loss is more stable than actual loss. It helps casinos avoid over-rewarding one unlucky session or under-rewarding one lucky session.
Why does floor yield matter?
Casino floor space is limited. Floor yield helps management decide whether a game, slot bank, or area earns enough for the space it occupies.
Can a high-revenue game still be bad business?
Yes. If labor, comps, promotion cost, volatility, disputes, or opportunity cost are too high, revenue may not translate into good profit.
Deeper Insight
A casino economics quick reference should prevent three bad habits.
First, it should stop players from mistaking low edge for low total cost. Second, it should stop employees from mistaking busy games for profitable games. Third, it should stop managers from mistaking actual win for good strategy.
The cleaner view is this:
| Business Question | Best Starting Metric | What Else Must Be Checked |
|---|---|---|
| What is this player worth? | Theoretical loss | Reinvestment, risk, behavior, trip pattern |
| Is this table productive? | Win, drop, average bet, decisions | Labor, disputes, limits, volatility |
| Is this slot machine earning? | Coin-in, win, hold | Location, denomination, maintenance, player type |
| Is this promotion working? | Incremental theo | Cost, redemption, cannibalization |
| Is this floor area strong? | Floor yield | Guest flow, game mix, brand value |
| Is this offer safe? | Player response and risk signals | Responsible gambling and credit concerns |
Industry-level data can show broad patterns, but property-level decisions require local truth. A regional casino, a luxury resort, a cruise casino, a locals casino, and a VIP-focused property do not all optimize the same way.
Formula / Calculation
Theoretical Win = Average Bet × Decisions Per Hour × Hours Played × House Edge
Actual Win = Buy-In + Credits + Fills - Closing Inventory - Opens
Floor Yield = Casino Win / Floor Space
Net Promotion Value = Incremental Theo - Promotion Cost
Reinvestment Rate = Comp Value / Theoretical Loss
Formula Explanation in Plain English
Theoretical Win estimates expected casino value. Actual Win shows the table or area result after inventory movement. Floor Yield measures how hard the floor space is working. Net Promotion Value tells whether an offer added enough expected value to pay for itself. Reinvestment Rate shows how much of the player’s expected loss is being returned as comps or offers.
No single formula runs the casino. The job is to read the formulas together.
