Vig is the fee a sportsbook charges for taking your bet. It is built into every line you see, and it is how sportsbooks make money regardless of which side wins.

You will not see a separate charge on your bet slip. Instead, the vig is embedded into the odds themselves. Understanding how it works helps you recognize the true cost of each wager and why shopping for better prices can matter over time.

This guide explains what vig means, how it is calculated, how it varies by bet type, and what it means for your returns as a bettor. 

What Is Vig?

Vig, short for vigorish, is the margin a sportsbook builds into its odds so that it profits on both sides of a bet. It is also commonly called the juice or the cut.

The concept comes from bookmaking — rather than simply offering fair odds on two outcomes, a sportsbook prices both sides slightly below true probability. That gap between what they pay out and what they take in is the vig.

Every bet type carries vig. It appears in point spread odds, totals, moneylines, parlays, and futures. The amount varies, but it is always present. A sportsbook that consistently took balanced action and charged no vig would break even. The vig ensures they do not.

How Is Vig Calculated?

The most common way vig appears is through the standard -110 pricing on point spreads and totals. This is also called standard juice or the dime line in some markets.

The -110 Standard Explained

On a standard point spread, you might see both sides priced at -110. That means you must risk $110 to win $100 on either side. 

• Kansas City Chiefs -3.5 (-110)
• Philadelphia Eagles +3.5 (-110)
• To win $100 on either side, you risk $110.
• That extra $10 per $100 won is the vig.

If the sportsbook takes equal action on both sides, it collects $110 from the losing side, pays out $100 in winnings plus the $100 stake to the winning side, and keeps $10. That $10 per bet cycle is the vig revenue.

How to Calculate the Vig Percentage

You can calculate the vig percentage by converting each side's odds to implied probability, adding them together, and subtracting 100.

• Both sides at -110:
• Implied probability of -110 = 110 / (110 + 100) = 52.38%
• Total implied probability = 52.38% + 52.38% = 104.76%
• Vig = 104.76% - 100% = 4.76%
• That 4.76% is the sportsbook's built-in edge on this market.

A perfectly fair market with no vig would add up to exactly 100%. Any total above 100% represents the sportsbook margin. 

Vig on Moneylines

On moneyline bets, the vig is less visible but works the same way. The gap between the favorite's price and the underdog's price contains the margin.

• Example: NBA game
• Los Angeles Lakers -160
• Golden State Warriors +140
• Lakers implied probability: 160 / (160 + 100) = 61.54%
• Warriors implied probability: 100 / (140 + 100) = 41.67%
• Total: 61.54% + 41.67% = 103.21%
• Vig: 3.21%
• A fair line might be Lakers -150 / Warriors +150,
• which would total exactly 100%.

The wider the spread between the favorite and underdog prices, the higher the vig. Tight moneylines on close games often carry less vig than heavy-favorite matchups.

Vig on Parlays

Parlays carry a higher effective vig than straight bets because the vig compounds across each leg. Each time you add a leg, the sportsbook's built-in edge multiplies.

• Two-leg parlay, both sides at -110:
• True fair payout for 2-leg parlay at 50/50 odds: +300
• Actual sportsbook payout: approximately +260
• The difference represents the compounded vig across both legs.
• The more legs you add, the wider that gap grows.

This is why parlay payouts often look attractive but carry more built-in cost than placing the same bets individually.

Vig by Bet Type

Vig varies depending on the type of bet and how the sportsbook prices it. Here is a general comparison across common bet types.

Futures carry the highest vig of any market because all possible outcomes must be priced, and the total implied probability across the entire field can exceed 130% or more for popular markets like championship winners.

How Vig Affects Your Long-Term Returns

The vig is why breaking even on sports betting requires winning more than 50% of your bets. At standard -110 pricing, you need to win approximately 52.4% of your wagers just to stay flat.

• Break-even win rate at -110:
• You risk $110 to win $100.
• If you win 52 out of 100 bets:
• Winnings: 52 x $100 = $5,200
• Losses: 48 x $110 = $5,280
• Net: -$80 (still losing slightly)
• The exact break-even rate at -110 is 52.38%.
• At -105, it drops to 51.22%.
• At -115, it rises to 53.49%.

Even a small reduction in the vig you pay lowers the bar you need to clear to be profitable. That is the practical argument for line shopping and seeking out reduced juice sportsbooks.

What Is Reduced Juice?

Reduced juice refers to sportsbooks that offer point spreads and totals at better pricing than the standard -110 on each side. Common reduced juice lines include -108, -105, or even -101 on both sides.

The savings on individual bets may seem small, but over a large number of wagers the difference in vig paid compounds significantly.

• Comparing 1,000 bets at -110 vs -105:
• At -110, break-even requires winning 52.38% of bets.
• At -105, break-even requires winning 51.22% of bets.
• That 1.16% difference in required win rate translates to
• roughly 12 additional wins needed per 1,000 bets at -110
• compared to -105.

Comparing odds across multiple betting apps is the most direct way to reduce the vig you pay over time. Even on markets where all books offer -110, small differences appear on moneylines and props that can add up.

Vig vs Juice — Is There a Difference?

No. Vig and juice refer to the same thing. Both describe the built-in margin a sportsbook charges on a bet. Juice is more common in casual conversation, while vig is slightly more formal. You may also hear it called the cut, the take, or the house edge, though house edge is more commonly used in casino contexts.

Some bettors use vig to refer specifically to the percentage margin and juice to describe the dollar cost of a particular bet, but in practice the terms are used interchangeably across the industry.

How to Find the Fair Odds Without the Vig

You can strip the vig out of any market to find the underlying probability each sportsbook is assigning to each outcome. This is sometimes called the no-vig line or the fair line.

The process involves converting both sides to implied probability, normalizing them so they add up to 100%, and converting back to odds. 

• Example: Finding the no-vig line
• Market: Patriots -110 / Jets -110
• Step 1: Convert to implied probability
• Both sides: 110 / 210 = 52.38%
• Total: 104.76%
• Step 2: Normalize each side
• Patriots: 52.38 / 104.76 = 50%
• Jets: 52.38 / 104.76 = 50%
• Step 3: Convert back to odds
• 50% = +100 (even money)
• The no-vig line is -100 / +100.
• The sportsbook's -110 / -110 represents their profit margin over that.

Most sharp bettors use no-vig lines as a reference point to evaluate whether a sportsbook is offering a price above or below fair value on a given side.

Does Vig Vary by Sport?

Yes. Vig levels are not uniform across sports, and sportsbooks adjust their margins based on the liquidity and competitiveness of each market.

• NFL and NBA: The most liquid and competitive markets. Vig on spreads and totals is typically close to the -110 standard. Major sportsbooks compete aggressively on price in these markets.
• MLB: Run line and totals often priced at -110 / -110, but moneylines on close games can carry slightly more vig due to the higher frequency of low-scoring outcomes.
• NHL: Puck line and totals follow similar patterns to MLB. Moneyline vig can vary depending on how evenly matched teams are.
• College sports: Vig can be higher than professional markets due to lower liquidity and less sharp action.
• Props: Among the highest vig markets available. Player props often carry 6% to 10% margins or more, which is why experienced bettors are selective about which props they target.
• Futures: Consistently the highest vig market. The cumulative implied probability across all outcomes on a championship future frequently exceeds 120% to 140%.

How to Minimize the Vig You Pay

• Shop for the best line: Having accounts at multiple sportsbooks lets you compare prices before placing a bet. Even a one-point difference in a spread or a few cents on a moneyline can shift whether you are getting value.
• Focus on markets with lower vig: Spread and total markets at the major books tend to carry less vig than props and futures. If you are not confident you have an edge, bet types with lower built-in margins give you a better base.
• Use reduced juice books where available: Some sportsbooks offer -108 or -105 on both sides of spread markets as a standard. Over hundreds of bets, the savings are meaningful.
• Be selective with parlays: The vig compounds with each leg added. A two-leg parlay already carries roughly double the effective vig of a single bet. More legs means more margin working against you.
• Calculate the no-vig line on futures: Before placing a futures bet, strip the vig to understand the true probability the book is assigning. A team at +500 may look attractive until you realize the fair price is closer to +400 after removing the margin.

Responsible Gambling

Sports betting should be approached as entertainment. The vig means every bet starts at a slight disadvantage, which is why managing your bankroll and setting limits matters. Only wager what you can afford to lose and avoid chasing losses.

What Is Vig in Sports Betting FAQ

What does vig mean in sports betting?

Vig, short for vigorish, is the margin a sportsbook builds into its odds to ensure it profits on bets. It is also called the juice. Rather than offering fair odds, sportsbooks price both sides of a bet slightly below true probability and keep the difference as revenue.

How much is the vig on a standard bet?

On a standard point spread or total priced at -110 on both sides, the vig is approximately 4.76%. That means for every $100 in theoretical winnings, the sportsbook retains about $4.76 in margin across both sides of the market.

Do all sportsbooks charge the same vig?

No. Vig varies by sportsbook and by market. Some books offer reduced juice on spread and total markets, pricing lines at -108 or -105 instead of the standard -110. Moneylines and futures can also vary significantly across sportsbooks, which is why comparing prices before betting is worth doing.

What win rate do I need to beat the vig?

At standard -110 pricing, you need to win approximately 52.38% of your bets just to break even. At -105, that drops to about 51.22%. At -115, it rises to roughly 53.49%. The vig is the reason winning at sports betting over the long run requires consistently finding edges, not just picking more winners than losers.

Is vig the same as the house edge?

They refer to a similar concept but in different contexts. Vig specifically describes the margin built into sports betting lines. House edge is the term more commonly used in casino gaming to describe the mathematical advantage the house holds in games like blackjack or roulette. In sports betting, vig and juice are the standard terms.

Do parlays have higher vig than straight bets?

Yes. Each leg you add to a parlay compounds the vig from the individual legs. A two-leg parlay at -110 per leg carries roughly twice the effective vig of a single bet. The more legs you add, the further the parlay payout strays from true fair odds, which is how sportsbooks generate significant margin from parlay markets.

Which bet type has the highest vig?

Futures consistently carry the highest vig of any market. When you add up the implied probability of all possible outcomes on a championship winner market, the total frequently exceeds 120% to 140% or more. That excess over 100% represents the sportsbook margin, which is spread across every outcome in the field.

Can I find a no-vig line?

You can calculate one. By converting both sides of a market to implied probability, normalizing them to add up to 100%, and converting back to odds, you can derive the fair line without the sportsbook margin. This gives you a reference point to evaluate whether a given price offers value relative to what the book considers the true probability.
