What Is Hold Percentage?
Hold (also called vig, juice, or margin) is the sportsbook's built-in edge. When implied probabilities add up to more than 100%, the excess is the hold—the book's guaranteed profit margin.
📐 The Formula
Hold % = (Implied Prob A + Implied Prob B) - 100%
At -110/-110: 52.38% + 52.38% = 104.76% → 4.76% hold
Why Hold Matters
Lower hold means better odds for you. A 4% hold is standard, but some books offer 2-3% on competitive markets. Over time, betting at lower-hold books significantly improves your results.
