Totals betting in college basketball involves wagering on whether the combined score of both teams will finish over or under a number set by the sportsbook. With over 350 Division I programs playing vastly different styles — from up-tempo systems averaging 75+ possessions per game to grind-it-out defenses that slow the pace dramatically — the range of totals across a daily NCAAB slate is enormous. A game between two mid-major defensive teams might sit at 125, while a Big 12 shootout could be posted at 160 or higher. This stylistic diversity creates frequent opportunities where oddsmakers misprice games, particularly in early-season matchups or non-conference play when tempo data is still limited.
The most valuable totals spots often arise when two teams with contrasting pace profiles meet, forcing books to estimate how the tempo will settle. Bettors should monitor adjusted tempo rankings, recent lineup changes, and venue effects — altitude and arena noise can subtly influence scoring. Regarding vig, NCAAB totals typically carry standard -110/-110 juice at most books, but the sheer volume of games means shops vary more than they do on sides. Comparing vig across sportsbooks on totals is especially worthwhile during heavy slates like conference tournament week, where reduced juice on even a handful of bets compounds into meaningful savings over a full season.

Frequently Asked Questions
Which sportsbook has the lowest NCAAB totals vig?
LowVig.ag currently has the lowest vig at 3.79%, earning a grade of B+.
Why is college basketball vig so variable?
NCAAB has hundreds of teams and thousands of games per season. Major conference matchups attract decent volume and competitive vig, but mid-major and early-season games see far less action. Sportsbooks compensate with wider margins on lower-profile games.
When is NCAAB season?
College basketball runs from November through early April, culminating in March Madness (the NCAA Tournament). The tournament generates massive betting interest and typically features some of the best vig of the NCAAB season.
Does March Madness have better vig than regular season?
Generally yes. March Madness is one of the most heavily bet events in American sports. The flood of casual and sharp money forces books to tighten their lines. Tournament vig is often 1–2% lower than early-season college basketball.
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.
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, BetAnySports). 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 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.
