Hold & Vig Calculator


Calculate the sportsbook\'s hold (juice, vig) on any two-way or three-way market. The hold is the built-in margin Ohio sportsbooks bake into both sides of a line — find the no-vig fair odds and compare across operators.

What Is Hold?


The hold (also called vig or juice) is the margin built into both sides of a sportsbook market. A standard NFL spread of -110/-110 has implied probabilities of 52.4% / 52.4%, totaling 104.8%. The extra 4.8% is the sportsbook\'s edge — the price you pay for the option to wager.

Lower hold = better odds for the bettor. Ohio sportsbooks typically run 4-5% hold on standard markets and 5-10% on player props. Reduced-juice promos (-105 lines or +100) lower the hold to ~2.4% — meaningfully better long-term ROI.

Sharp bettors use this calculator to find no-vig fair odds, which serve as a proxy for the true probability of an outcome. A bet that beats no-vig fair odds is theoretically +EV.
