What Is Vig in Sports Betting?

Updated July 2026

Every bet you place has a price, and it is not the amount you stake. It is the vig. At VigVerdict we treat the vig as the single most important number in a sportsbook review, because it is the one cost that quietly follows you on every wager you ever make. This guide explains what vig is in sports betting, how to calculate it from American odds in under a minute, and how sharp bettors pay less of it.

What does vig mean in sports betting?

Vig is the margin a sportsbook charges for accepting your bet. As Legal Sports Report puts it, vig is "the amount that the sportsbook charges to take wagers." The word comes from the Yiddish and Russian term for winnings. In betting slang it is used interchangeably with the juice, the cut, or the hold.

Here is the key idea: a fair coin flip pays even money, or +100 in American odds. If a sportsbook offered a true coin flip at +100 on both sides, it would make nothing over time. So instead it shortens the price. It offers both sides at -110, meaning you risk 110 dollars to win 100. That small shading is the vig, and because it sits on both sides of the line, the book is guaranteed a profit when the action is balanced.

How does the vig work in a real line?

Picture a game with two evenly matched teams, both priced at -110. Two bettors each stake 110 dollars, so the book holds 220 dollars total. One side wins and collects 210 dollars back, the 110 stake plus 100 in profit. The sportsbook keeps the leftover 10 dollars. That 10 dollars is the vig.

There are two common ways to express how much that costs you:

• The overround: the two -110 sides imply a combined 104.76 percent chance of an outcome, when real probabilities can only add up to 100 percent. That extra 4.76 percent is the vig.
• The hold: the 10 dollars the book keeps out of 220 wagered works out to about 4.5 percent of total handle on perfectly balanced action. This is what the sportsbook actually banks.

Both numbers describe the same thing from different angles. For a bettor, the overround is the more useful figure, because it tells you how far the price is tilted against you before the game even starts.

How to calculate vig from American odds

You can work out the vig on any two-way market in three steps. It takes about a minute with a phone calculator.

Step 1: Convert each side to implied probability

For negative odds, divide the number by itself plus 100. For positive odds, divide 100 by the number plus 100.

• Negative odds: |odds| divided by (|odds| + 100)
• Positive odds: 100 divided by (odds + 100)

Step 2: Add the two implied probabilities together

A fair market would total 100 percent. A real market totals more.

Step 3: Subtract 100 percent

Whatever is left over is the vig.

Worked example, a -140 / +120 moneyline:

• The -140 favorite: 140 divided by 240 equals 58.33 percent.
• The +120 underdog: 100 divided by 220 equals 45.45 percent.
• Total: 58.33 + 45.45 equals 103.79 percent.
• Vig: 103.79 minus 100 equals 3.79 percent.

Vig by line: how the price changes

Not every book charges the same vig, and not every line carries -110 juice. Here is what standard two-sided pricing costs across common lines. Lower is better for you.

Line (both sides)	Implied prob per side	Combined total	Vig
-102 / -102	50.50%	100.99%	0.99%
-105 / -105	51.22%	102.44%	2.44%
-108 / -108	51.92%	103.85%	3.85%
-110 / -110 (standard)	52.38%	104.76%	4.76%
-115 / -115	53.49%	106.98%	6.98%

The gap matters more than it looks. Moving from a -115 book to a -105 book cuts your vig from nearly 7 percent to under 2.5 percent. Over a full season of betting, that difference is real money that stays in your account instead of the sportsbook's.

What is a no-vig or fair line?

Once you know the vig, you can strip it out to see the sportsbook's true opinion. This is called the no-vig or fair line, and it is how sharp bettors judge whether a price is actually good.

To remove the vig, divide each side's implied probability by the combined total. On a -110 / -110 line, that is 52.38 divided by 104.76, which equals exactly 50 percent. So the fair line behind a -110 / -110 market is a true coin flip, +100 on each side. The 10 cents of juice on each side is pure vig.

A line is not good just because your team is on it. It is good only when the price beats the true probability. The vig is what stands between those two numbers.

Why the vig matters more than any bonus

Sportsbooks market bonuses, boosts and promo codes loudly, and they keep the vig quiet. That is not an accident. A one-time bonus is a marketing cost the book pays once. The vig is a cost you pay on every wager, forever. At -110, you must win 52.38 percent of your bets just to break even. Win exactly half, which sounds like breaking even, and you are slowly losing.

This is the entire reason our reviews run a Juice Check on every sportsbook we cover. A book with a slick app and a big welcome offer but consistently high vig will cost a regular bettor far more than a plainer book that prices at -105. Price beats packaging. When we compare two major books head to head, as in our FanDuel vs DraftKings breakdown, the juice is one of the first things we measure.

How to pay less vig

• Line shop. The same game is priced differently across books. Holding accounts at several licensed operators lets you take the lowest juice available on each bet.
• Look for reduced-juice pricing. Some books and some markets run at -105 or better instead of -110. Over time, that is one of the biggest edges available to a casual bettor.
• Avoid big parlays. Vig compounds with every leg you add, which is why parlays carry a much larger hold than single bets.
• Bet the number, not the logo. Loyalty to one app is loyalty to its vig. Compare the actual price before you click.

Frequently asked questions

What is the vig on a standard bet?

On a standard -110 line offered on both sides, the vig is about 4.76 percent measured as the overround. The sportsbook keeps roughly 4.5 percent of total money wagered when the action is balanced.

Is vig the same as juice?

Yes. Vig, vigorish and juice all refer to the same thing: the margin the sportsbook builds into its odds. Different bettors and regions just prefer different words for it.

Do I pay the vig if my bet loses?

The vig is not a separate charge you pay on a losing bet. It is baked into the odds on every bet you place, win or lose. You pay it through a slightly worse price than a fair line would give you.

What win rate do I need to beat the vig?

At -110 odds you need to win 52.38 percent of your bets to break even. Anything below that and the vig grinds your bankroll down over time, even if your record looks close to even.

Which sportsbooks charge the lowest vig?

Reduced-juice books and specific low-hold markets price below the -110 standard, sometimes at -105 or better. The lowest effective vig on any given bet is whatever the best available price is across the licensed books you can access, which is why line shopping wins.
