FAQ
What is a vig calculator?
A vig calculator helps bettors calculate the sportsbook’s built-in margin, also known as the vig, juice, or bookmaker commission.
How does a vig calculator work?
The calculator converts both sides of a betting market into implied probabilities and determines how much margin the sportsbook has built into the odds.
What is a vig in sports betting?
Vig, short for vigorish, is the commission sportsbooks charge for accepting bets. It is built into the odds offered on each side of a market.
How much vig is included in sportsbook odds?
The amount of vig, also know as the sportsbook’s commission or margin, varies by market and operator. Standard point spread and total markets often contain around 4% to 5% vig. Removing the vig from betting odds can help bettors determine the true implied probability of an outcome.
What are no-vig odds?
No-vig odds are the fair odds after the sportsbook’s margin has been removed. They provide a more accurate estimate of the true probability of an outcome.
Why is removing the vig important?
Removing the vig allows bettors to compare odds more accurately and identify whether a bet offers potential value.
Can I use this calculator for any betting market?
Yes. As long as you have the American odds for both sides of a two-outcome market, the calculator can estimate the vig and no-vig probabilities.
Is this calculator accurate?
Yes. It uses standard sportsbook formulas to calculate implied probabilities, bookmaker margin, and no-vig probabilities based on the odds entered.
