What Is the Vig in Sports Betting? How the Juice Works and How to Pay Less

Say you and a buddy wager opposite sides of Bills-Jets at the same sportsbook, $110 each at odds of -110. One of you wins $100. The other loses $110. Between the two of you, you're down $10, and you didn't even have to pick a winner to get there. That $10 is the vig.

The vig, short for vigorish and also known as juice, is the sportsbook's cut of every sports bet. You won't see it as a fee on your bet slip because it's built into the betting line, so you pay it by winning a little less than you risk. At the standard vig of -110, it works out to about 4.5% of all the money bet on a game. Understand the vig and you'll understand why most bettors lose over time, and what the ones who don't do differently.

How the vig works

If a bet were a true coin flip with no house cut, the fair price would be even money, +100: risk $100, win $100. Sportsbooks don't offer that. They price both sides of a point spread or total at -110 instead, so you risk $110 to win a $100 profit. Our guide to the standard -110 price walks through it in detail.

Now look at it from the sportsbook's side. If it takes $110 on each side, it holds $220. Whoever wins gets back $210, their $110 plus $100 in winnings. The book keeps $10 no matter which team covers. Ten dollars out of $220 is 4.55%. That's the vig the sportsbook takes, and it's how sportsbooks make their money when the betting is balanced.

Real books are rarely perfectly balanced, and they move lines to manage that. But the vig is why a sportsbook doesn't need to know who wins to make money. It only needs you to keep betting.

Where the word comes from

Vigorish is old gambling slang, usually traced through Yiddish to the Russian word for winnings. Bookmakers and loan sharks used it for their cut long before online sportsbooks existed, which is why people also say "the vig" for the interest on a street loan. In betting it means the house's cut, nothing more.

How to calculate the vig

You can work out the vig on any betting line in two steps. First turn each side's odds into an implied probability. For a negative price, divide the odds by the odds plus 100. For a positive price, divide 100 by the odds plus 100. Then add the two sides up to get the total implied probability. If reading the prices themselves is still new, start with our guide to reading a betting line.

Real probabilities add up to 100%. Everything over 100% is the book's margin. To turn that into the vig as a share of the money bet, divide 1 by the total and subtract it from 1. For -110 on both sides that's 1 minus 1/1.0476, about 4.55%. More on the first step in our guide to implied probability.

That last row is a common price on player props. A bettor who lives on props at -120 pays almost twice the vig charged on a point spread at -110.

How to remove the vig and find fair odds

Once you know the total, you can strip the vig out and see what the book really thinks. Divide each side's implied probability by the total.

Take a moneyline price of -150 on the favorite and +130 on the underdog. The implied chances are 60% and 43.48%, which add up to 103.48%. Divide each by 1.0348 and you get about 57.98% and 42.02%. Those are the no-vig chances, which work out to fair odds of about -138 and +138.

That tells you something useful. The no-vig price of +138 says the book has the dog at about 42%. If you think it wins 45% of the time, your fair price is about +122, so the +130 on offer is worth taking. If you think it wins 40%, you know to stay away. Removing the vig is how sharp bettors check whether a price is worth taking.

Why the vig matters more than you think

At -110 you have to win 52.38% of your bets just to break even. Pick winners 52% of the time, which sounds pretty good, and you still lose money.

Take 100 bets, each one $11 to win $10, with 52 wins and 48 losses. You win $520 and lose $528, so you're down $8. Make the exact same picks at -105, risking $10.50 to win $10, and you win $520 and lose $504. You're up $16. The price alone flipped you from losing to winning, which is why the lowest vig you can find matters as much as the picks.

The vig also stacks. In a parlay, every leg carries its own juice, and the edges multiply. That's part of why parlays are so profitable for sportsbooks. Our parlay payout guide shows how the numbers build up leg by leg.

Where the vig is higher

The standard vig on main spreads and totals at a big US sportsbook is the cheapest bet you can make. Online sportsbooks tend to charge a higher vig on player props, alternate lines, live betting, period lines, and futures, where adding up the implied probabilities of every team in a title market can get you well past 100%. None of those are bad bets by definition. They just cost more, so you need a bigger edge to make them pay.

How to beat the vig, or at least pay less

You can't avoid the vig at a sportsbook, but you can pay less of it.

Shop around. Different sportsbooks post different prices on the same game. Finding -105 instead of -110, or +135 instead of +130, is the easiest money in betting. It takes thirty seconds to find the best price, and over a season the lower vig adds up to real money on your potential payout.

Look for reduced juice. Some sports betting sites offer reduced vig, -105 on spreads and totals, every day, and others run reduced-juice promotions.

Bet the main markets. If you're just starting out, the main point spread and total carry the lowest vig at most books. Save props and parlays for when you know what you're paying.

And be pickier. Every wager costs you a little vig, and the house edge doesn't care how confident you felt, so a bet you're lukewarm on has to clear that bar too. Fewer, better bets beat more bets almost every time.

The vig on Paid2Bet

The game odds on Paid2Bet are American odds with the vig built in, the same as you'd see at any sportsbook, so the math above works on every line. On a Reduced Juice Day, which we announce with a banner on the Bet page, spreads and totals that would normally be -110 are offered at -105 for single bets and parlay picks with your Free or Paid balance. The bet slip shows the regular price next to it so you can see what you're saving. Moneylines, team totals, props and teasers stay at their regular odds.

Start paying attention to the second number on every line, not just the spread. Once you see the juice, you'll never look at a -120 the same way again.
