“Vig” is short for vigorish, the built-in fee sportsbooks charge to guarantee profit regardless of the bet's outcome. It's commonly seen in standard -110 odds, where both sides of a bet require you to wager $110 to win $100. That small edge ensures the bookmaker wins over time – even when bettors break even overall.
Using a Vigorish Calculator helps you quantify this hidden cost and assess the true value of the odds you're betting on.
Our Vig Calculator determines the juice by analyzing the odds from both sides of a betting market. Whether you're working with American, Decimal, or Fractional odds, the tool:
If the total exceeds 100%, you're paying a vig. The higher the number, the worse the value for the bettor.
To use our Vigorish Calculator:
It's a simple, effective way to spot overpriced lines and find better value across books.
Let's say you're looking at an NFL game where both teams are listed at -110 odds.
Conclusion: In this case, the sportsbook is charging a 4.76% vig, meaning that's the built-in edge they're profiting from regardless of which team wins.
Many sportsbooks hide their edge behind complex odds formatting. Our Vig Calculator strips away that confusion and gives you a transparent look at how much you're actually paying to place a bet.
Whether you're a sharp bettor or a casual player, knowing the vig is essential for making profitable decisions. The lower the vig, the better the value.
What does a vig mean in betting?
A vig, or vigorish, is the cut that sportsbooks take from each wager. It's the reason odds on both sides of a bet don't add up to a fair 100%.
How do I calculate vigorish manually?
Convert both sets of odds to implied probabilities, add them, and subtract 100%. The result is the vig percentage.
Why should I care about the vig?
Because it directly affects your long-term profitability. Lower-vig sportsbooks give you a better chance of beating the market.
Can I use this calculator for live odds?
Yes! Just plug in the current odds from your sportsbook to reveal how much they're charging in real-time.
