What Is Vig in Sports Betting? Vigorish, Juice, and the Cut You Pay on Every Bet

Every bet you place on the Jackpot.bet sportsbook has a price baked into the odds before the game even starts. 

It does not appear as a separate fee on your bet slip. It does not come off your winnings in a visible line. It is built directly into the numbers you see, and it is called the vig.

Vig, vigorish, and juice all mean the same thing: the sportsbook's built-in commission on every wager. 

Once you know how it works and where it is hiding, you can make sharper decisions about which bets to place and which to avoid.

What Is Vig, Vigorish, and Juice?

Vig is short for vigorish, a commission embedded into betting odds that ensures the sportsbook makes money regardless of which side wins. 

It is not collected as a separate charge. Instead, the odds are set slightly below fair value so that the book keeps a margin on every market it offers.

All three terms describe the same thing. Vig and juice are the informal terms you will hear from bettors and analysts. Vigorish is the formal version. In practice, they are completely interchangeable.

The most common form of vig in sports betting is the -110 line on point spreads and totals. Instead of offering even money (+100) on a 50/50 proposition, the sportsbook asks you to risk $110 to win $100. That extra $10 is the vig.

How the Vig Works - A Simple Example

Here is the math laid out cleanly. Two bettors each place a $110 wager on opposite sides of an NFL point spread, one on Team A and one on Team B.

• Total collected: $220

• Winner paid out: $110 stake returned + $100 profit = $210

• Sportsbook keeps: $10

That $10 the book keeps regardless of the outcome is the vig. As long as action is balanced on both sides, the book does not care who wins, it profits either way. At scale, across thousands of bets per day, that margin compounds into significant revenue.

How to Calculate the Vig

The calculation uses implied probability, the win percentage embedded in any set of odds.

Step 1 - Convert each side to implied probability:

• Negative odds: |odds| ÷ (|odds| + 100)

• Positive odds: 100 ÷ (odds + 100)

Step 2 - Add both implied probabilities together. 

A fair market sums to exactly 100%. Any total above 100% reveals the vig.

Step 3 - Subtract 100 to find the overround. 

Divide by the total to find the hold percentage.

At standard -110 pricing, the sportsbook holds roughly 4.55% of every dollar wagered on that market. Drop to -105 lines and the hold falls to 2.38%, nearly half.

How Much Vig Do Sportsbooks Charge?

Vig is not a fixed percentage. It varies significantly depending on the type of bet you place, and the differences are much larger than most bettors realize.

Spreads and totals are the most competitive markets. Standard -110 pricing is 4.55%, and sharper books regularly offer -105 on both sides, cutting that in half.

Moneylines depend on the gap between favorite and underdog. A close match might carry 3% vig. A heavy favorite at -300/+240 pushes that closer to 6–7%.

Parlays are where vig compounds most aggressively. Each leg carries its own vig, and the book multiplies them together rather than paying true combined odds. 

A standard 5-leg parlay at -110 per leg carries roughly 21% effective vig, nearly five times what a single spread bet costs.

Futures and outright markets are the worst values on the board. A 32-team Super Bowl futures market can carry 25–33% vig, meaning the book expects to keep a third of every dollar wagered before the season even starts. 

The Break-Even Win Rate You Actually Need

Because the vig sits inside every price, you do not break even at 50%. You need to win more often just to stay flat. Here is exactly how much more:

At the standard -110 line, you need to win 52.38% of bets to break even long-term. That is the baseline every sports bettor is working against before they have picked a single game correctly.

Moving from -110 to -105 drops the required rate to 51.22%, a 1.16-point reduction that has a real impact across a full season of wagering.

How to Reduce the Vig You Pay

You cannot eliminate the vig entirely, but you can reduce how much of it you absorb.

Stick to Spreads and Totals

The vig gap between a single spread bet and a 5-leg parlay is enormous. Every leg you add compounds the cost. 

Prop bets and futures carry even higher margins. For bettors focused on long-term returns, single-game spread and total markets are where the vig is smallest.

Shop the Best Line

The difference between -110 and -105 is not dramatic on any single bet, but across a hundred bets at $100 each it is the difference between paying $1,100 in vig or $550. Getting the best number available on every bet is one of the clearest edges a disciplined bettor can maintain.

Watch for Juice Shifts

When a line moves from -110/-110 to -115/-105 without the spread changing, the book is loading one side with extra vig rather than moving the number. 

That shift is itself information about where the action is flowing, and it increases the cost of the side being penalized.

Limit Your Parlay Legs

The vig on a 5-leg parlay is not five times the vig on a single bet, it is closer to twenty times. Long parlays are how sportsbooks generate the bulk of their margin from recreational bettors.

Conclusion

The vig is the one constant in sports betting, it is there on every spread, every moneyline, every total, every parlay, regardless of who wins. Most recreational bettors never think about it, which is exactly how sportsbooks prefer it.

Once you see it in the odds, you start making different decisions. Single-game spread and total markets keep the cost at its lowest.

Long parlays and futures push it into territory that is hard to overcome even with a genuine edge. Keep the vig small, track it across your bet types, and the math shifts in your favor over time.

Frequently Asked Questions

Is vig the same as juice? 

Yes, vig, vigorish, and juice are three terms for the same thing. All three describe the commission embedded in betting odds that gives the sportsbook its margin on every market.

Do all sportsbooks charge vig? 

Yes. Every sportsbook charges vig on every market it offers. It is how they generate revenue. The amount varies, sharper books charge less, recreational books charge more, but it is always present.

What is the vig on a standard point spread? 

At standard -110 pricing on both sides, the vig is approximately 4.55% of total handle. Some books offer -105 lines, cutting that to around 2.38%.

Always check both sides of the spread before placing, if one side is -115 and the other is -105, the vig is being loaded onto the -115 side.

Why do parlays have more vig than single bets? 

Each leg of a parlay carries its own vig, and the sportsbook multiplies the margins across all legs rather than paying out true combined odds. A 2-leg parlay at -110 per leg pays around +264 when fair odds would be +300. 

A 5-leg parlay pays around +2,436 when fair combined odds would be roughly +3,100. The gap grows with every leg added.
