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.

UEFA Champions League qualification betting follows a unique seasonal pattern that begins in earnest during late spring. Preliminary round odds typically surface in May following the conclusion of domestic league seasons, with the actual qualification rounds running from June through August. The first qualifying round kicks off in mid-June, followed by second round action in late June, third round matches in early August, and playoff rounds concluding by late August. Sportsbooks release comprehensive qualification futures immediately after domestic seasons end in May, capitalizing on the extended window before meaningful matches begin.

Off-season qualification betting centers heavily on outright qualification futures for clubs from smaller leagues, with books offering "to reach group stage" props for teams like Ferencvaros, Dynamo Kiev, or Red Star Belgrade. Transfer window activity creates substantial betting opportunities, particularly when established clubs lose key players or when ambitious sides make significant signings. Books also offer head-to-head qualification markets between clubs likely to meet in early rounds, plus aggregate score totals for two-leg ties. The most valuable futures often involve clubs from leagues ranked 10th-20th in UEFA coefficients, where a single marquee signing can shift qualification odds by 30-40 points.

Qualification betting margins follow predictable seasonal patterns, with books offering their loosest lines immediately after domestic seasons conclude in May when information gaps are widest. Value typically peaks during the June international break before first round matches, as recreational bettors focus minimal attention on preliminary rounds. The sharpest lines emerge once qualification rounds begin, particularly for playoff stage matches involving bigger-name clubs. Historical analysis shows that managerial appointments and high-profile departures drive the most significant odds movements, often more than player transfers, as tactical preparation proves crucial in knockout qualification scenarios.

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.
