The true fair odds after removing the sportsbook's built-in margin.
No-vig odds (also called fair odds or true odds) represent what the odds would be if the sportsbook charged zero commission. They're calculated by removing the overround from the implied probabilities and converting back to odds.
No-vig odds are valuable because they represent the market's true estimate of each outcome's probability. Many sharp bettors use no-vig odds from sharp books like Pinnacle as a proxy for the true probability of an event.
Comparing the no-vig line to the odds you're getting tells you whether you're getting value on a bet.
Pinnacle posts Yankees −140 and Red Sox +125. Implied: 58.33% and 44.44%, totaling 102.77%. The no-vig line removes that 2.77% overround.
Yankees no-vig = 58.33 / 102.77 = 56.76%, which converts to a fair price of roughly −131. Red Sox no-vig = +131. Now when FanDuel hangs Boston at +145, you know the fair price is +131, meaning FanDuel is offering roughly +5.6% EV on the dog. Every serious +EV tool in the industry — OddsJam, Unabated, BonusBell — runs on no-vig fair-line conversion from a trusted sharp book.
