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.
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.
Why use a vig calculator?
It helps bettors understand the true probabilities behind betting odds and evaluate markets without the sportsbook’s built-in commission.
