No-Vig Calculator
Every bookmaker builds a margin — the vig or 'juice' — into their odds, so the implied probabilities of a market add up to more than 100%. This free no-vig calculator removes that margin to show the fair odds and the true probability of each outcome.
Enter the odds for every outcome. It devigs the market (logarithmic method) and returns the fair, no-vig price plus the bookmaker's total margin — the number you're really paying to bet.

Frequently asked questions
What are no-vig odds?
The fair odds you'd get if the bookmaker took no margin. They're the best available estimate of an outcome's true probability, and the benchmark you compare other prices against to find value.
How do you remove the vig?
You rescale the raw implied probabilities (1/odds) so they sum to exactly 100%. Simple normalisation divides each by the total; the logarithmic method used here adjusts for favourite–longshot bias for a more accurate fair line.
Why compare against a sharp book?
The no-vig line of a sharp bookmaker like Pinnacle is one of the market's best probability estimates. If a soft book offers longer odds than that fair line, the bet is +EV.
