How to Use This Calculator

The no-vig calculator removes the sportsbook's margin (vig/juice) from a market to reveal the true fair odds. This is essential for finding +EV opportunities and understanding what probability the market actually implies.

Why Remove the Vig?

Sportsbooks build their profit margin into both sides of a bet. At -110/-110, the implied probabilities add up to 104.76%, not 100%. The extra 4.76% is the vig. Removing it shows you the true 50/50 fair odds.

Inputs

  • Odds Side 1: American odds for one outcome
  • Odds Side 2: American odds for the opposite outcome

How to Use Fair Odds

  • Compare fair odds to odds at other sportsbooks to find value
  • If a book offers better odds than fair, you have +EV
  • Use sharp books (Pinnacle, Circa) to derive fair odds for comparison
  • Track how often your estimated probabilities beat market fair odds
