Vigorish (Vig)
Vigorish is the commission a sportsbook charges on bets, built into the odds to guarantee operator margin regardless of the outcome.
What it means in practice
Vigorish — commonly shortened to vig or called juice — is the built-in margin a sportsbook applies to every betting market. When a sportsbook sets odds on a two-outcome event, the combined implied probabilities exceed 100%. That surplus is the vig, and it represents the operator's theoretical profit on the market. Understanding vig is essential for anyone working in sportsbook affiliate programmes because it directly determines the betting margin that drives RevShare calculations.
For a standard -110/-110 American odds market (e.g. a coin-flip equivalent), each side implies roughly 52.4% probability, totalling 104.8%. The 4.8% overround is the vig. In practice, sportsbook vig varies by sport, market type, and competitive pressure — major leagues carry tighter margins (2-5%) while niche markets may carry 8-12%. Live or in-play betting markets typically have wider vig because the operator faces greater pricing risk as events unfold.
From an affiliate perspective, vig matters because it determines the sportsbook hold percentage and ultimately the net revenue on which sportsbook RevShare is calculated. A sportsbook with tighter vig attracts sharper bettors but generates less margin per bet, while wider vig produces higher margins but may reduce betting volume. Affiliates driving traffic to high-vig operators may see stronger RevShare earnings per bettor but lower conversion rates.
