No-Vig Calculator

Enter both sides of a 2-way market (Over/Under, Moneyline favorite/dog, etc.) and see the "fair" odds with the vig stripped out. Useful for line shopping and EV analysis.

Fair Odds B (no-vig)–

How to use: If a sharp book (e.g. Pinnacle) prices a market at -110/-110, the no-vig fair odds for both sides are +100 (50/50 true probability). If you can find a -105 line at another book, that's a +EV bet — you're getting better than fair odds. Read the odds explained guide for context.
