Every bet placed at a licensed US sportsbook carries a built-in cost most casual bettors never think to calculate. That cost is the vig — also called juice or vigorish — and it sits quietly inside the odds on every market, from a standard NFL point spread to a niche player prop. Understanding how vig works is the first practical step toward making smarter wagering decisions, whether a bettor is just getting started or has years of daily fantasy experience behind them. Americans legally wagered $147.91 billion on sports in 2024, a 23.6% increase from the prior year, which means the dollar value of vig paid across the country is substantial and growing.

What exactly is sportsbook vig and how does it work?

The standard sportsbook vig is approximately 4.76% on most markets, built into the pricing of both sides of a wager. The clearest illustration is a standard point spread bet priced at -110 on each side. A bettor must risk $110 to win $100, rather than the $100 that a perfectly fair market would require. When two bettors take opposite sides, the book collects $220 in total wagers and pays out $210 to the winner, keeping $10 — that retained $10 is the vig in action. The hold, which is the percentage of total handle a sportsbook retains as profit after paying winning bettors, is a direct function of this vig structure applied across every market on the board.

A practical example: a bettor who places 500 wagers of $110 each at -110 odds over a season risks $55,000. Even in a scenario where they win exactly half their bets — a coin-flip outcome — they collect $50,000 in returns and net a loss of $5,000. That gap reflects the vig, not bad luck. This is why shopping for the best available line across multiple books, a practice known as line shopping, is the single most actionable habit a serious bettor can develop. Reviewing the Best Online Sportsbooks in the USA — 2026 Rankings is a useful starting point for identifying which platforms consistently offer sharper pricing.

How does vig vary across different bet types and platforms?

Vig is not uniform across every market. Standard point spreads and game totals typically carry the familiar -110/-110 pricing, but moneylines, parlays, props, and futures can carry significantly higher implied vig because the pricing asymmetry between sides is harder for the average bettor to detect. A two-team parlay, for example, pays roughly 2.6-to-1 at most sportsbooks when the true mathematical fair price is closer to 3-to-1, with the gap representing compounded vig on each leg. Player props, which carry wide opening lines and limited liquidity, frequently carry even more embedded margin.

One emerging competitive pressure worth noting is CFTC-regulated prediction markets, which carry approximately a 4.5% lower vig gap compared to traditional sportsbooks. While these platforms are structurally different from licensed state-regulated books, their pricing model puts quiet pressure on the industry to narrow margins over time. For now, the major licensed operators remain the primary option in legal betting states, and the difference between those operators on any given market is meaningful enough that comparing them closely — as covered in the DraftKings vs FanDuel: Bonus, Odds, and Payout Speed Compared breakdown — can meaningfully reduce the long-run vig a bettor pays.

How do vig rates compare across common bet types?

Bet Type Typical Pricing Approximate Implied Vig Notes
Point Spread (standard) -110 / -110 ~4.76% Most common market; vig is consistent across licensed books
Two-Team Parlay Pays ~2.6-to-1 ~10%+ Fair price is closer to 3-to-1; vig compounds with each added leg
Player Prop Varies widely Often 6–10%+ Wider lines and lower limits make vig harder to detect
CFTC Prediction Market Exchange-style pricing ~0.3% or lower Approximately 4.5% lower vig gap vs. traditional sportsbooks

Does vig affect how sportsbook bonuses are valued?

Vig interacts directly with bonus value in ways that many new bettors overlook. Because bonus bets do not return the stake on a winning wager — only the profit is paid out — a bettor using a $100 bonus bet at -110 odds collects roughly $91 in profit rather than $191 in total return. Running that bonus bet through a wagering requirement multiple times while paying vig on each wager erodes the face-value further with each cycle. Wagering requirements across licensed US sportsbooks range from 5x to 25x, meaning the effective cash value of a bonus depends heavily on both the playthrough multiple and the odds at which each wager is placed. The Sportsbook Bonus FAQ: How Wagering Requirements and Bonus Bets Work covers these mechanics in detail. Availability of bonuses and specific terms vary by state; always confirm eligibility in your jurisdiction before depositing.

Understanding vig is ultimately about making an informed decision each time a wager is placed — not about avoiding betting altogether, but about recognizing the cost built into every market and factoring it into long-run expectations.
