Perguntas frequentes
What is bookmaker hold (margin)?
The hold or margin is the bookmaker’s built-in profit. It is the amount by which the total implied probabilities exceed 100%. A 5% hold means the bookmaker expects to keep 5 cents of every dollar wagered.
What is a good hold percentage?
Lower is better for bettors. Most sportsbooks have a hold of 4-10% on standard markets. Sharp bookmakers may offer 2-3% margins, while some prop bets can have 15%+ margins.
What are fair odds?
Fair odds are what the odds would be if the bookmaker had zero margin. They represent the true mathematical probability of each outcome as estimated by the market.
