No-Vig Calculator FAQs

The fee baked into every line. A -110/-110 market looks like 50/50 but the implied probabilities total 104.76% — that extra 4.76% is what the book keeps no matter who wins.

Convert both sides to implied probabilities, sum them to find the overround, then divide each probability by the overround. The result is the fair price with the fee stripped out.

Fair odds are the market’s honest read on the outcome. Any book priced better than fair is giving you an edge; any book priced worse is charging extra vig.

Pinnacle is the canonical sharp. If you can’t reach it, the closing line at your own book is a strong proxy — bookmakers converge as game time approaches.

Convert each side: -110 implies 110/210 = 52.38%. Both sides sum to 104.76%. Subtract 100% to get the vig: 4.76%. The fair probability for each side is 52.38/104.76 = 50% — a true coin flip.

Same method, three outcomes instead of two. Convert each price to implied probability, sum all three, and the amount above 100% is the vig. Divide each probability by the total to get the fair odds for home, draw, and away.

Juice is another name for the vig — the sportsbook’s built-in commission on every market. A standard -110/-110 line carries about 4.76% juice. This calculator strips it out so you can see the true fair price.
