Quick Answer
Understanding vig/juice in betting
Vig (juice/hold) is the sportsbook's margin. Calculate it by adding implied probabilities: standard -110/-110 lines equal 52.4% + 52.4% = 104.8%, meaning 4.8% vig. No-vig fair odds would be +100/+100 (50%/50%). Lower vig means better value for bettors.

Frequently Asked Questions
Common questions about vig
What is the vig (juice) in sports betting?
The vig, also called juice or hold, is the commission sportsbooks charge on bets. It's built into the odds so that the total implied probability exceeds 100%. For example, -110 on both sides of a spread means the book profits regardless of the outcome.
How do I calculate the hold percentage?
Add the implied probabilities of all outcomes. For 2-way markets: IP1 + IP2 - 100% = Hold. For -110/-110: 52.38% + 52.38% = 104.76%, so the hold is 4.76%. For 3-way markets, add all three probabilities and subtract 100%.
What is considered low vig?
Standard vig is 4.5-5% (-110/-110). Low vig books offer -105/-105 or better (2.4% or less). Some offshore books offer -102/-102 on select markets. Even 1-2% vig reduction significantly impacts long-term profitability.
How does vig affect my long-term profits?
Vig is the main reason most bettors lose long-term. At standard -110 vig, you need to win 52.4% to break even. Reducing vig to -105 lowers the break-even point to 51.2%. Over thousands of bets, this difference adds up to significant money.
What are no-vig fair odds?
No-vig (or "true") odds remove the sportsbook's margin to show what odds would be if there were no house edge. They're calculated by dividing each implied probability by the total implied probability, then converting back to odds.
How this works
Calculations follow the published mathematics of the game — combinatorics for cards, probability theory for dice, and expected-value accounting for wagers. Results are verified against independent references (primarily Wizard of Odds). No calculation here is an opinion or recommendation; it is arithmetic applied to the rules of the game.
