No-Vig Odds
Remove the sportsbook margin (vig) to find the fair probabilities and odds for each outcome. Enter the odds for each of two outcomes using the selected format. Learn what no-vig odds mean
What Are No-Vig Odds?
No-vig odds represent the fair, true odds of a betting market after removing the sportsbook's built-in profit margin (vigorish or "vig"). Sportsbooks don't offer perfectly balanced odds. They include a margin that ensures they profit regardless of the outcome. For example, both sides of a bet might be priced at -110, which implies a combined probability of 104.76% (not 100%). The extra 4.76% is the bookmaker's edge.
By calculating no-vig odds, you can determine what the fair probability of each outcome should be and what the odds would be in a perfectly efficient market with zero margin. This is crucial for value betting: if your estimated probability of an outcome is higher than the no-vig probability, you've potentially found a +EV (positive expected value) opportunity.
This calculator takes the odds for both sides of a two-outcome market (e.g., Team A vs. Team B, Over/Under), removes the vig proportionally, and shows you the fair probability and fair odds for each side. Use it to identify where sportsbooks are offering value and where they're charging too much vig.
