What is the vig (and the no-vig price)?
The vig, or juice, is the margin a sportsbook builds into a market. It makes both sides' implied probabilities add up to more than 100%. The no-vig price removes that margin so the two sides sum to exactly 100%, revealing the book's true opinion.
How to remove the vig from odds
Convert both sides to implied probability and add them up; the total will be over 100% (that excess is the hold). Divide each side's probability by that total to normalize it back to 100%. The result is the fair, no-vig probability, which converts straight back to fair odds.
Why no-vig odds matter
No-vig odds are the closest thing to a fair line. Comparing a book's price to the no-vig price tells you how much edge you are giving up, and comparing no-vig prices across markets is how sharp bettors find value and beat the closing line.
Skip the vig entirely on BettorEdge
Devigging tells you the fair price; BettorEdge lets you actually bet closer to it. Because you trade with other people instead of a book, there is no built-in house margin eating your edge.

Frequently asked questions
What is a no-vig calculator?+
It removes the sportsbook's margin from a two-way market and shows the fair odds and true probability of each side, the price you would see if the book took no cut.
How do you calculate no-vig odds?+
Add the implied probabilities of both sides, then divide each by that sum so they total 100%. Convert the normalized probabilities back to odds for the fair, no-vig price.
What is a good hold percentage?+
Lower is better for you. Sharp two-way markets often hold 2 to 4%, while parlays and props can hold far more. The calculator shows the hold on whatever market you enter.
Why is it called no juice or no vig?+
Juice and vig are slang for the sportsbook's built-in margin. Removing it gives the no-juice or no-vig price, the fair line underneath the book's markup.
