What Is the Vig? Vigorish and What Betting Really Costs
Updated 2026-07-12 · 5 min read
The vig — short for vigorish, also called juice or the cut — is the commission built into betting odds. It's why a coin-flip bet pays less than even money: at standard -110 odds you risk $110 to win $100, and that gap is the bookmaker's fee for taking the bet.
The vig is the reason the phrase "the house always wins" is arithmetic rather than superstition. It's also the number this platform is named after: VigCheck exists to show you what that built-in cost has actually added up to in your own betting.
The math at -110
Take a standard point spread priced at -110 on both sides. Two bettors each stake $110 on opposite sides — $220 total in the pool. The winner gets back their $110 stake plus $100 in winnings: $210. The book keeps the remaining $10.
That $10 on $220 of total handle is about 4.5% — the book's expected take on a perfectly balanced market, no matter which side wins. For you as an individual bettor, breaking even at -110 requires winning 52.38% of your bets, not 50%. The 2.38-point gap is the vig, extracted one bet at a time.
The vig varies — and it's not always visible
- Standard spreads and totals usually run -110/-110, but promotional markets go lower and many books quietly price -112 or -115.
- Moneylines and futures carry vig inside asymmetric odds where it's harder to see — the implied probabilities of all outcomes sum to well over 100%, and the excess is the house margin.
- Parlays multiply vig: every leg carries its own margin, which compounds. The convenience of one big payout is among the most expensive products in the book.
- Same-game parlays and boosted markets can carry margins several times higher than a standard spread.
How vig compounds over a season
The vig looks small per bet and becomes large through volume. A bettor placing $200 on a spread every day wagers roughly $73,000 over a year. At a ~4.5% house margin, the expected cost of that volume is over $3,000 — before any variance, tilt, or bad beats. That's the baseline fee for playing, paid whether the picks are sharp or not.
This is why total handle (everything you've staked), not just net result, matters for understanding your gambling. Two bettors can both be "down $2,000," but the one who churned ten times the volume paid far more vig to get there — and is running much better than they think, or much worse.
What's your real vig?
Your effective vig is what gambling has actually cost you as a fraction of the money you've cycled through it. You can't compute it from memory, and no single platform's dashboard will show it — it lives in your complete transaction history.
VigCheck reconstructs it from your bank records: total deposits, total withdrawals, net position per platform and overall, and the pattern over time. That's the number the name refers to. Know your numbers.
Frequently asked questions
What does vigorish mean and where does the word come from?
Vigorish entered American English in the early 1900s, most commonly traced through Yiddish to the Russian word vyigrysh, meaning winnings or profit. It originally described a lender's or bookmaker's cut and survives today as "vig" or "juice."
What win rate do I need to beat the vig?
At standard -110 odds you need to win 52.38% of your bets just to break even. Most recreational bettors sit near 50% on spread bets over the long run, which means the vig converts high volume into steady losses regardless of skill perception.
Is the vig the same as the house edge?
They're the same idea in different clothing. "Vig" usually describes the bookmaker's margin on sports odds, while "house edge" describes the statistical advantage built into casino games. Both quantify the structural cost of playing.
