↓ 7-day trend: Average vig has improved by 0.05 percentage points over the past week (from 4.60% to 4.55%). Sportsbooks are tightening their lines — a good sign for bettors.

NBA betting offers one of the deepest and most liquid markets in North American sports. The high-scoring nature of the game — teams averaging around 110-115 points per contest in recent seasons — creates substantial action on totals, while the 82-game regular season provides a massive sample size for modeling. Point spreads, moneylines, totals, player props, quarter and half lines, and an ever-expanding menu of same-game parlays make the NBA one of the most heavily bet sports globally. The sheer volume of games (up to 15 on a single night) forces sportsbooks to price hundreds of markets simultaneously, which creates opportunities for sharp bettors to find soft numbers.
Vig on NBA markets tends to be tighter than in many other sports, particularly on sides and totals for marquee matchups. Standard -110/-110 lines are common, and competitive books frequently shade toward -105 or better on spreads and totals to attract volume. However, margins widen considerably on derivative markets like team totals, alternate lines, and especially player props, where books can embed 8-12% or more in juice without most bettors noticing. Moneyline vig also expands on heavily lopsided games, where a -600 favorite paired with a +420 underdog can carry significant hidden cost. Comparing vig across books on these less efficient markets is where bettors can recover the most value.
The NBA regular season runs from mid-October through mid-April, with playoffs extending into June. Vig tends to be most competitive during the heart of the regular season — December through March — when betting volume peaks and books compete aggressively for handle. Early-season lines can be softer as books and bettors alike calibrate to roster changes, new coaching schemes, and rotation adjustments. The playoff period draws enormous public money, which can create value on less popular sides but also tightens headline markets considerably. Injuries are the single most impactful variable in NBA odds-setting; the absence of a single star can swing a spread by 5-7 points. Load management, back-to-back scheduling, and rest days create late-breaking lineup news that moves markets sharply, rewarding bettors who monitor injury reports up to tip-off.

Frequently Asked Questions
Which sportsbook has the lowest vig for NBA?
Pinnacle currently has the lowest average vig for NBA at 2.95%, earning a grade of A.
How do sportsbook odds compare for NBA?
We compare 20 sportsbooks for NBA. The vig ranges from 2.95% (Pinnacle) to 5.39% (BetRivers).
When do small vig differences matter for NBA?
The top two books (Pinnacle and LowVig.ag) are separated by just 0.21%. While small, this adds up over volume — a bettor placing $1,000/week saves roughly $2 per week by choosing the lower-vig book.
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 three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM 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 a letter scale based on average vig: A+ (under 2%) is exceptional, A (2–3%) is excellent, B+ (3–4%) is above average, B (4–5%) is the industry standard, C (5–6%) is below average, and D (above 6%) indicates high-juice markets.
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 three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM 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.
