No-vig odds calculator
What are the true odds behind a sportsbook's price?
A book offering -145 / +125 is asserting probabilities that sum to more than one. Removing that margin gives the favourite:
| additive | 57.37% |
| multiplicative | 57.11% |
| power | 57.50% |
| shin | 57.37% |
Consensus 57.34%, and the four methods disagree by 0.39 points. Every other no-vig calculator returns one number.
Where the number comes from
Everything above was computed by the same engine that prices bets, at the moment this page was built — not typed into a template. The build fails if a figure appears here and not in the engine's own output.
