About This Guide
Understand how the vig (juice) is built into basketball betting odds at -110 and what it means for your long-term returns.
The vig — also called the juice — is the sportsbook's built-in commission, and understanding it is probably the single most important concept before you place your first basketball bet. Once you see how it works, you'll never look at a -110 line the same way again.
What does -110 actually mean in basketball betting?
On virtually every point-spread and totals bet you'll find at a US sportsbook, both sides are priced at -110. In American odds, that means you must wager $110 to win $100 in profit. The extra $10 above your potential profit is the vig. On a two-sided market where both sides sit at -110, that pricing implies a house margin of approximately 4.5%. So the sportsbook doesn't need to predict games perfectly — it just needs roughly balanced action on both sides and the vig takes care of the rest. That's how sportsbooks make money on basketball, game after game, season after season.
Why does that 4.5% matter for your long-term returns?
It might sound small, but compound it across hundreds of bets and it becomes a serious headwind. To break even at -110, you need to win roughly 52.4% of your bets — not 50%. That gap between 50% and 52.4% is entirely the vig eating into your bankroll. Casual bettors who ignore this math tend to wonder why they seem to "almost break even" but never quite get there. Now you know why. Shopping for reduced-juice lines (say, -108 instead of -110) at the Best Sportsbooks for Betting on Basketball in 2026 is one of the most underrated edges available to everyday bettors.
Is the vig the same on every bet type?
Not even close. The standard -110/-110 spread applies cleanly to point spreads and game totals, but moneylines, parlays, and props all carry their own implied vig — and it's often higher. On a heavily favored team's moneyline, the juice can be baked in more aggressively and is harder to spot at a glance. Our breakdown of Basketball Bet Types: Spreads, Moneylines, Totals & More walks through each market in detail, and if you want to zero in on moneylines specifically, What Is a Moneyline Bet in Basketball? explains exactly how the implied probabilities on both sides always add up to more than 100% — that overage is the vig in disguise.
Do sportsbooks publish their hold percentages?
State gaming regulators sometimes publish aggregate hold data, but specific figures must be sourced from official state reports before you can trust them — we never cite hold numbers without going back to primary sources. What we can tell you is that the hold varies by book, by market, and by time of year (playoff props, for instance, can carry heavier juice than regular-season spreads). Legality and published hold data are both state-dependent, so always confirm the rules in your jurisdiction before depositing. If you want to compare how two of the biggest books handle pricing in practice, our FanDuel vs DraftKings: Which Is Better for Basketball Bets? breakdown looks at exactly that.
