No-Vig / Fair Odds Calculator

Remove the sportsbook's commission (vig) to reveal the true mathematical probability and fair odds for any market.

How to Use This Calculator

Sportsbooks build a profit margin ("vig" or "juice") into their lines. Stripping this margin away reveals the true fair market probability.

Select Market Type Choose between a 2-Way market (e.g. NFL spread, NBA moneyline) or a 3-Way market (e.g. NHL 60-min, Soccer draw).
Enter Sportsbook Odds Input the Decimal odds being offered for each side of the wager.
Evaluate True Probability Use the calculated Fair Probability (%) as your baseline input for the +EV or Kelly Criterion calculators.

Sharp Tip: Low-vig sportsbooks take smaller cuts, meaning higher payouts over time. Aim to shop for books with a total overround under 4.0%.
