Totals betting in college basketball asks bettors to predict whether the combined final score of both teams will land over or under a number set by the sportsbook. With 351 Division I teams and vast disparities in pace, offensive efficiency, and defensive capability, NCAAB totals present a uniquely rich market. A game between two up-tempo mid-major programs might post a total of 155, while a grind-it-out Big Ten matchup could sit at 128 — and the factors driving each number are fundamentally different.

The totals market becomes most valuable when bettors can identify pace mismatches, altitude effects (games in Colorado or Wyoming, for example), or late-season fatigue that the line hasn't fully captured. Monitoring KenPom's adjusted tempo and offensive/defensive efficiency ratings is essential for serious totals bettors. Regarding vig, NCAAB totals typically carry standard -110/-110 juice at most books, but the sheer volume of games — sometimes 80+ per day — means less-bet matchups can see wider vig or softer lines that sharper bettors can exploit. Comparing vig across books on these lower-profile totals is where meaningful savings add up over a full season.

Frequently Asked Questions

What is a totals (over/under) bet?

A totals bet is a wager on whether the combined score of both teams will be over or under a number set by the sportsbook. For example, an NFL total of 47.5 means you're betting whether the final combined score will be 48+ (over) or 47 or fewer (under).

How does totals vig compare to other markets?

Totals vig varies by sport but is generally moderate — between moneyline and spread vig. Totals attract less volume than spreads but more than most prop markets, putting them in a middle ground for vig. Weather and injury news can cause totals to move significantly, sometimes affecting vig.

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.
