Hold Calculator

Hold is the margin baked into a market after you take the best available price on each side. It is the sportsbooks' collective cut of every dollar wagered. Enter the best odds for both sides of a market and this calculator adds the implied probabilities together; whatever exceeds 100% is the hold you are paying.

Sharp bettors gravitate toward low-hold markets because their bets keep more value, and a negative hold means the two books disagree enough to create an arbitrage. Popular markets like NBA sides tend to run tight holds, while obscure props and niche leagues can hide margins of 5% or worse, so check before you bet.
