📊 Annual Summary
📖 The Theo Formula
Average Bet = Your typical wager per decision
Hands/Hour = Game speed (60 for blackjack, 400+ for slots)
Hours = Total playing time tracked
House Edge = Mathematical advantage (0.5% blackjack, 5-15% slots)
Example: A $25 blackjack player at 60 hands/hour with 0.5% house edge generates $7.50/hour in theoretical loss. Over a 4-hour session, that's $30 theo. At a 25% comp rate, the player earns about $7.50 in comps—enough for a nice meal at the buffet.
Understanding Theoretical Loss and Casino Comps
Casino loyalty programs are built on a mathematical foundation that many players don't fully understand. The key concept is theoretical loss (often called "theo")—the expected amount the casino will win from you based on probability, not your actual results. According to the American Gaming Association, player tracking and loyalty programs are now standard across the industry, with casinos investing billions in systems to accurately measure player value.
Why use theoretical loss instead of actual results? Because gambling is random in the short term. A player who wins $10,000 on a lucky night might have generated $500 in theoretical loss—and that's what they're valued at for comp purposes. This approach, documented in industry research from the UNLV International Gaming Institute, ensures consistent player valuation regardless of short-term variance.
How Casinos Calculate Your Value
Every time you use your player's card, the casino tracks your:
- Average bet size (estimated by floor supervisors for table games, exact for slots)
- Hours played (tracked by card swipes and pit observations)
- Games played (each has a different house edge and speed)
- Betting patterns (more sophisticated casinos track individual decisions)
For table games, pit bosses estimate your average bet every 15-20 minutes. Some players "bet spread"—betting more when being observed—but casinos are aware of this tactic. Modern systems use statistical analysis to identify unusual patterns and adjust ratings accordingly.
Game Speed: The Hidden Variable
One factor many players overlook is game speed. The table below shows typical decision rates and how they affect theoretical loss. As noted by gaming industry consultants, slot machines generate far more decisions per hour than table games, which is why they earn more comp points per dollar wagered despite having worse odds.
| Game | Decisions/Hour | Typical House Edge | Theo per $25 Bet/Hour |
|---|---|---|---|
| Blackjack (crowded) | 50-60 | 0.5-1.0% | $6.25-15.00 |
| Blackjack (heads-up) | 150-200 | 0.5-1.0% | $18.75-50.00 |
| Baccarat | 70-80 | 1.06% (Banker) | $18.55-21.20 |
| Roulette (European) | 35-40 | 2.70% | $23.63-27.00 |
| Craps (Pass Line) | 100-120 | 1.41% | $35.25-42.30 |
| Slots | 400-600 | 5-15% | $500-2,250 |
| Video Poker (9/6 JoB) | 400-500 | 0.46% | $46-57.50 |
Comp Rates and VIP Tiers
The percentage of theoretical loss returned as comps varies widely based on your player tier, the casino, and even your relationship with your casino host. According to Vegas Insider and industry sources, typical comp rates are:
- Basic/Standard players: 10-20% of theo returned as comps
- Mid-tier players: 20-30% of theo, plus occasional offers
- Premium/VIP players: 30-40% of theo, plus free rooms and airfare
- High rollers/Whales: 40-100%+ of theo, including loss rebates
The highest-value players often negotiate specific deals with casino hosts. Some whales receive loss rebates (getting back 10-20% of actual losses), private jet service, and unlimited comps on rooms, food, and entertainment.

Maximizing Your Comp Value
If you're going to gamble anyway, you should maximize the value you receive. Here are evidence-based strategies:
- Always use your player's card. Untracked play is lost value—you're giving up comps for free.
- Consolidate your play. Playing at one casino builds tier status faster than spreading action across multiple properties.
- Play games with low house edge. Blackjack and baccarat earn similar comp rates per dollar bet but cost you less in expected losses.
- Ask for comps directly. Casino hosts have discretion—a polite request for a meal or room upgrade often works.
- Watch for multiplier promotions. Many casinos offer 2x-5x points during slow periods.
- Book through your host. Rooms booked through third-party sites may not count toward your tier status.
Don't Chase Comps
Comps should be a pleasant side benefit, not a reason to gamble more. The math is clear: you'll always give back more in expected losses than you receive in comps. As the National Council on Problem Gambling notes, viewing gambling as an "investment" in comps is a warning sign of problematic gambling thinking.
Online Casino Comp Programs
Online casinos typically offer more transparent comp programs than land-based venues. Points are calculated automatically based on wagering, and conversion rates to cash or bonuses are clearly stated. However, comp rates tend to be lower (often 0.1-0.5% of wagering), and the points system may have wagering requirements before cash withdrawal.

Frequently Asked Questions
What is theoretical loss in casino gambling?
Theoretical loss (theo) is the expected mathematical loss based on your betting activity and the house edge of the games you play. It's calculated as: Average Bet × Hands/Spins per Hour × Hours Played × House Edge. Casinos use theoretical loss, not actual results, to determine comp value because it provides consistent player valuation.
How do casinos calculate comp value?
Casinos typically return 10-40% of your theoretical loss as comps (free rooms, meals, show tickets, etc.). The comp rate varies by casino, player tier, and type of game. Higher-tier VIP players often receive 30-40% or more, while casual players might receive 10-20%. Some casinos use point systems where points can be redeemed for cash, comps, or rewards.
What is a good comp rate from casinos?
Comp rates typically range from 10-40% of theoretical loss. A rate of 20-30% is considered solid for regular players. VIP and high-roller programs often offer 30-50% or higher, plus additional perks like loss rebates. Online casinos may offer lower comp rates (10-20%) but often have more transparent point-to-cash conversion rates.
Why do casinos base comps on theoretical loss instead of actual loss?
Casinos use theoretical loss because it provides consistent, fair player valuation regardless of short-term luck. A player who wins $5,000 but generated $2,000 in theoretical loss is still valued at $2,000 for comp purposes. This system rewards playing time and betting level rather than penalizing lucky winners or over-rewarding big losers.
How can I maximize my casino comp value?
To maximize comps: (1) Always use your player's card when gambling, (2) Play games with lower house edge for the same comp value, (3) Consolidate play at one casino to reach higher VIP tiers, (4) Ask your casino host about special promotions, (5) Take advantage of multiplier days, and (6) Book rooms through your casino host rather than third-party sites.
What is the difference between comp points and cash back?
Comp points are earned through play and can be redeemed for various rewards (meals, rooms, merchandise), while cash back is direct money returned to you. Cash back is typically valued at 100% of its face value, while comp points may have variable value depending on redemption options. Some programs offer both, letting you choose your preferred reward type.
Do slot machines and table games earn comps at different rates?
Yes, slot machines typically earn comp points faster than table games because slots have higher house edges and faster play speed. However, table game players often receive better comp rates (percentage of theo returned) because their play is more valuable to the casino. A $25 blackjack player might earn fewer points per hour but receive a higher percentage back as comps.
