What Is the Vig in Sports Betting? Juice and Hold Explained

You bet a coin flip at -110 and win exactly half the time. You should break even, right? You do not. You slowly lose. The reason is a small, quiet number baked into every line on the board, and almost nobody starting out knows it is there. It is called the vig, and understanding it is the difference between thinking you are even and knowing you are behind.

The vig, also called the juice or the hold, is the sportsbook’s built-in commission. It is the cut the house takes on every bet, win or lose, in exchange for booking the action. You never see it billed as a fee. It is hidden inside the odds themselves.

Where the Vig Actually Lives

Look at a standard point spread or total. Both sides sit at -110. That does not mean even money. It means you risk $110 to win $100 on either side.

If the two sides were truly a coin flip, a fair price would be +100 both ways, bet $100 to win $100. That extra ten dollars on each side is the vig. The book is not predicting the game there. It is pricing in its own margin.

Why You Actually Need to Win More Than Half

Here is the part that stings. Because of that -110 price, breaking even is not a 50% record. You have to win about 52.4% of your bets just to stay flat.

Win exactly half of your -110 bets and you are not even, you are down. Those small holds compound over hundreds of bets into the reason the phrase “the house always wins” exists. The house is not beating you on any single game. It is collecting a toll on all of them.

Not All Vig Is Equal

The -110 you see on sides is actually the friendly version. On other markets the juice runs much steeper.

Heavy favorites, popular overs, and boosted parlays can carry far more vig than a standard spread, which is exactly why a parlay that feels like free money is often the worst price on the board. The more exotic and exciting the bet, the more room the book has to widen its cut, and the harder you have to hit just to break even.

How You Fight It

You cannot make the vig disappear. It is the cost of doing business with a sportsbook. What you can do is refuse to pay more of it than you have to.

The same bet is rarely priced the same everywhere. One book has a side at -110, another at -105, and over a season that gap is real money you keep. This is why seeing the number across the books you actually use matters, and it is exactly what LFG’s Games board is for, the same line, side by side, so you take the best available price instead of the first one you saw.

The Takeaway

The vig is the house’s hidden commission, tucked inside the odds on every bet you place. It is why -110 is not a coin flip and why you need roughly 52.4% just to break even. You cannot avoid it, but you can stop overpaying it by checking the price before you bet.

The bettors who last are not the ones who never pay the vig. They are the ones who never pay a cent more of it than they have to.
