What is "juice" or "vig" in sports betting?
An in-depth guide explaining juice or vig in sports betting and how arbitrage betting offers a superior alternative to overcome it.
What is "juice" or "vig" in sports betting?
Juice or vig in sports betting is the commission or fee that sportsbooks charge on bets, built into the odds to guarantee them a profit.
Understanding juice is essential because it affects potential payouts and the true odds of an event, making it a hidden cost bettors must overcome.
Arbitrage betting eliminates the guesswork around juice by exploiting differing odds across sportsbooks to secure guaranteed profits regardless of the vig.
What Is Juice or Vig?
Juice, also known as vigorish or vig, is the built-in commission sportsbooks charge on each bet. It ensures the bookmaker makes a profit regardless of the event outcome by adjusting odds slightly in their favor. For example, in a typical 50/50 bet, instead of offering true even odds, bookmakers set odds that imply a probability slightly above 50%, so they earn a margin.
- •Juice is the bookmaker’s fee to cover costs and ensure profit
- •It is reflected in odds that are less favorable than true probabilities
- •Common juice rates range around 5% but can vary
💡Basic Juice Example
If two teams are evenly matched, true odds would be +100 on both sides. A sportsbook might offer -110 on each to include juice, meaning you must bet $110 to win $100.
Implied probability for -110 odds = 110 / (110 + 100) = 52.4%, which exceeds 50%, reflecting the vig.
How Juice Affects Your Betting Outcomes
Juice reduces the expected value of your bets. Even if you correctly predict an outcome, the commission means you need to win more than 50% of your bets to break even. This hidden cost makes beating the sportsbook challenging over time. Understanding juice helps bettors gauge the true risk and reward.
- •Cuts into profits by requiring higher winning percentages
- •Makes consistently beating the sportsbook more difficult
- •Can vary between sportsbooks and bet types
Why Juice Varies
Sportsbooks adjust juice based on market demand, event popularity, and risk exposure. Higher juice may appear in niche markets or less liquid events to protect the bookmaker.
- →Popular events often have lower juice
- →Specialty bets may carry higher vig
- →Understanding these differences can improve betting value
💡Impact on Break-even Percentage
With -110 odds, you must win about 52.4% of bets to break even due to juice, not just 50%. This subtle difference is critical for long-term profitability.
Break-even win rate = Risk / (Risk + Reward) = 110 / (110 + 100) = 52.4%
Calculating Juice and Understanding Odds
Calculating juice requires converting odds to implied probabilities and comparing them to true probabilities. This can become complex with various bet types and multiple sportsbooks. Tools like ArbitUp automate these calculations, helping bettors identify when the juice is favorable or when arbitrage opportunities exist.
- •Juice calculation involves implied probability formula
- •Different formats (decimal, fractional, moneyline) require conversion
- •Automated tools simplify complex comparisons
💡Converting Moneyline Odds to Implied Probability
For positive odds: Implied Probability = 100 / (Odds + 100). For negative odds: Implied Probability = Odds / (Odds + 100).
Example: Odds -150 = 150 / (150 + 100) = 60% implied probability
Juice Across Different Betting Markets
Juice is present in all sports betting markets but varies by type. Point spreads and totals often have standardized juice around -110, while moneyline bets can have varying juice depending on the underdog or favorite status. Futures and proposition bets often have higher juice due to uncertainty and bookmaker risk.
- •Point spreads typically have consistent juice
- •Moneyline juice fluctuates with perceived team advantage
- •Futures and props generally carry higher juice
Arbitrage as a Solution
Arbitrage betting exploits differences in juice and odds between sportsbooks to guarantee a profit. By placing bets on all possible outcomes across different bookmakers, bettors eliminate juice impact and risk.
- →Arbitrage neutralizes juice by balancing bets
- →Requires monitoring multiple sportsbooks and quick calculations
- →Tools like ArbitUp can automate detection and betting amounts
💡Arbitrage Example Across Different Juice
If one sportsbook offers Team A at -105 and another offers Team B at -110, placing proportionate bets on both can guarantee profit despite juice.
Bet sizes calculated to cover all outcomes, ensuring total payout exceeds total stake.
Strategies to Manage Juice and Improve Profits
Smart bettors seek sportsbooks with the lowest juice or use betting exchanges to reduce commission. Shopping for the best lines and odds across multiple bookmakers minimizes juice impact. However, these methods require time and careful calculation, which arbitrage betting automates, removing guesswork and securing steady returns.
- •Line shopping to find lowest juice
- •Using betting exchanges with lower commissions
- •Arbitrage betting to bypass juice entirely
💡Line Shopping Benefit
Finding a sportsbook offering -108 odds instead of -110 reduces juice and increases expected value over time.
Lower juice means break-even win rate drops from 52.4% to about 51.9%
