NBA betting offers one of the deepest and most liquid markets in North American sports. The high-scoring nature of basketball — with teams averaging around 110-115 points per game in recent seasons — creates natural variance that oddsmakers must account for across spreads, totals, and player props. The sheer volume of games (each team plays 82 in the regular season, running from late October through mid-April, followed by playoffs extending into June) means sportsbooks are pricing hundreds of markets daily, and that competition generally works in the bettor's favor. The explosion of player prop markets has added another dimension entirely, though those lines tend to carry significantly higher margins than traditional sides and totals.
For standard NBA spreads and totals, vig tends to be moderately tight compared to other major sports, largely because of the market's liquidity and the number of books competing for action. A typical spread might be offered at -110/-110, but sharper books frequently push into the -108 or -105 range on select lines. Moneyline margins widen considerably on mismatched games where heavy favorites are involved, making spread betting the more efficient market for most bettors. Totals generally carry similar juice to spreads, while first-half and quarter lines often feature slightly wider margins due to lower betting volume.
Seasonal timing matters. Early-season lines tend to be softer as books calibrate rosters after offseason turnover, presenting opportunities for bettors who've done their homework on rotation changes and new acquisitions. The vig picture also shifts during the playoffs, when increased public interest and betting volume often leads books to tighten margins on headline games. Injuries are the single most impactful factor in NBA odds movement — a star player's absence can swing a spread by 3-5 points — making lineup monitoring essential. Rest days, back-to-back scheduling, and travel also create meaningful edges, particularly later in the regular season when teams manage minutes more aggressively ahead of the postseason.

Frequently Asked Questions
Which sportsbook has the lowest NBA vig?
LowVig.ag currently has the lowest vig at 3.16%, earning a grade of B+.
How does NBA vig compare to NFL?
NBA vig is generally 1–2% higher than NFL because per-game betting volume is lower despite the longer season. However, NBA still attracts enough action to keep vig competitive — especially for popular matchups and playoff games.
When is NBA season?
The NBA regular season runs from mid-October through mid-April, with playoffs extending through June. The All-Star break falls in mid-February. Off-season runs July through October, though futures markets may open earlier.
Does NBA vig differ between regular season and playoffs?
Yes. Playoff games, especially Conference Finals and the NBA Finals, attract significantly more betting volume. This increased liquidity pushes sportsbooks to compete harder on price, and playoff vig is typically 0.5–1.5% lower than regular season.
Which NBA market has the lowest vig?
NBA point spreads usually carry the lowest vig because they attract the most balanced action. Moneylines on lopsided matchups (heavy favorites) often have higher vig because books need wider margins to manage risk on one-sided games.
What is vig (vigorish) in sports betting?
Vig — short for vigorish, also called juice or overround — is the margin a sportsbook builds into its odds. It's the difference between the true probability of an outcome and what the odds imply. Lower vig means you keep more of your winnings on every bet. For example, a standard -110/-110 line has about 4.76% vig.
How often is this data updated?
We pull fresh odds from The Odds API every hour, on the hour (UTC). Each snapshot captures the latest lines from every sportsbook that has posted odds. The timestamp at the top of the page shows the most recent refresh.
How is the vig grade calculated?
Each sportsbook is graded on average vig: A+ (under 2%) is exchange-level pricing, A (2–3%) very competitive, B+ (3–4%) above average, B (4–5%) the industry standard, C+ (5–6%) slightly below average, C (6–7%) below average, D (7–8%) high vig, D− (8–10%) very high, F (10%+) predatory.
Why does lower vig matter for bettors?
Lower vig directly impacts your long-term returns. A bettor placing $1,000 per week at a book with 4% vig loses roughly $40/week to the house edge. At 2% vig, that drops to $20/week — a $1,040 difference over a year. For serious bettors, shopping for lower vig is one of the most reliable ways to improve profitability.
What sportsbooks do you track?
We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnything). Data comes from The Odds API, which aggregates real-time lines from licensed sources.
How We Calculate These Numbers
- Data Source
- All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
- Update Frequency
- We pull a fresh snapshot of every tracked market every hour, on the hour (UTC). Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
- Vig Calculation
- Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
- Per-Market Breakdown
- We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
- Grading Scale
- Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exchange-level pricing. A (2–3%) is very competitive. B+ (3–4%) is above average. B (4–5%) is the industry standard — a -110/-110 line is 4.76%. C+ (5–6%) is slightly below average. C (6–7%) is below average. D (7–8%) is high vig. D− (8–10%) is very high vig. F (10%+) is predatory pricing. See the full Vig Index Methodology for formulas, worked examples, and known limitations.
- Trend Tracking
- We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
