What Is the Casino House Edge?
Defining the House Edge
The house edge is the percentage of each wager that a casino expects to keep over the long term. For example, if a game has a 5% house edge, the casino will retain $5 for every $100 wagered, on average.
- Mathematical Advantage: The house edge is carefully calculated using probability and payout ratios to ensure the casino profits over time.
- Long-Term Measure: It’s important to remember that the house edge is a long-term metric; in any short gaming session, individual players can experience wins or losses that don’t reflect the house edge.
How the House Edge Affects Players
The higher the house edge, the more likely you are to lose money over time. Lower house edge games offer better odds, allowing players to enjoy more of their winnings or reduce losses over extended play.
How Is the House Edge Calculated?
Understanding Probability and Payout Ratios
Calculating the house edge involves comparing the game’s payout structure to the probability of each outcome. For example, in roulette, the probability of hitting a single number is 1 in 37 for European roulette (1 in 38 for American), but the payout is only 35 to 1, creating a house edge.
- Probability: The likelihood of each possible game outcome.
- Payout Ratios: The amount paid for winning bets relative to the probability of those bets occurring.
Example Calculation: Roulette
In European roulette, with one zero, the house edge is 2.7%. Here’s how it’s calculated:
- Winning Chance: 1/37 (one number out of 37 total numbers).
- Payout: 35 to 1 for a single-number bet.
- House Edge: (37 – 1) / 37 x 100 = 2.7%
The American roulette version, which has an additional zero, has a house edge of 5.26%, making it less favorable to players.
