No-Vig Fair Odds Calculator

A no vig fair odds calculator is used to back out "fair" odds from a market. This tool can be used to compare markets and odds, as well as find the implied win percentages for a given team.

The implied win percentage can be from a sports betting model or calculated using the no vig "fair" odds from a sharp sportsbook. Finding the no vig "fair" odds from the sharpest sportsbook in the world (you now know what it is!) is the industry standard for fair win probability.

Many bettors determine a proper stake using the Kelly Criterion. We'll go through an example with the no vig fair odds calculator. Let's say you want to bet on the Los Angeles Rams vs their opponent. The sharpest sportsbook in the world has Rams +105 moneyline odds and their opponent moneyline -105 odds as well.

Using our no vig calculator, we can determine that the fair odds for the Rams are +100 (50% win probability) and their opponent is also +100 (50% win probability). The sportsbook vig in this example is 4.76%.

You can use this information to compare other sportsbooks and find value. If another sportsbook is offering the Rams at +110, you know you're getting better than fair odds and should consider placing that bet.
