Remove the vig to reveal true market odds
Every sportsbook includes a built-in profit margin, known as the vig or juice, which inflates the odds slightly in their favor. The No-Vig Calculator strips out that margin to reveal the true, fair odds and win probabilities for both sides of a market. This allows bettors to better compare prices across books, spot positive EV opportunities, and evaluate market efficiency.
For example, if a game has odds of -110 on both sides, the implied probabilities sum to over 100%, reflecting the sportsbook's edge. Using the no-vig calculator removes that edge and recalculates the true probabilities so they add to exactly 100%. In this way, you get a more accurate sense of each team's true chance of winning.
Tip: Use sharp market odds (from the sharpest sportsbooks) as inputs to get the most reliable no-vig estimates.
Frequently Asked Questions
A No-Vig Calculator removes the sportsbook’s built-in profit margin (vig or juice) from the odds, giving you the true fair odds and win probabilities for each side of a bet.
Sportsbooks include vig to ensure a profit regardless of the outcome. The vig acts as their built-in house edge by slightly skewing the odds in their favor on both sides of the market.
You enter the market odds for both sides of a bet. The calculator then removes the vig and returns the fair win probabilities and corresponding fair odds for each outcome.
The No-Vig percentages represent the true win probabilities for each outcome after removing the sportsbook’s edge. These add up to 100%, unlike market odds which usually add up to more due to vig.
By comparing the No-Vig fair odds to the odds offered by sportsbooks, you can identify positive expected value (EV) bets where the sportsbook is offering a better price than the true probability suggests.
No, different sportsbooks may apply different vig depending on the market, event, and popularity of the bet. Using the sharpest market lines gives the most accurate fair odds.
Yes, you can use the No-Vig Calculator for moneylines, spreads, totals, and prop bets as long as you have the odds for both sides of the market.
