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.

The Mestis regular season typically runs from late September through late February or early March, followed by a playoff bracket that extends into March and occasionally into early April. Preseason exhibitions and tournament matches generally take place in August and early September, and that's also when Finnish sportsbooks begin posting futures odds for the upcoming campaign. Because Mestis operates as Finland's second-tier professional ice hockey league — one step below Liiga — its betting ecosystem is considerably thinner, meaning oddsmakers devote fewer resources to modeling these lines and sharper bettors can find exploitable edges early in the cycle.

Off-season futures markets for Mestis are relatively limited compared to Liiga but still actionable. Championship winner odds are the most widely available, typically posted by late August, and they reflect the summer's player movement — which is substantial in Mestis, where roster turnover between seasons can exceed 50% on some clubs. Relegation and promotion-related markets also carry weight, as teams jockeying between Mestis and Liiga face dramatically different roster construction incentives. Key off-season catalysts for odds movement include Liiga-to-Mestis player loans and reassignments, coaching changes at clubs like KeuPa HT, Jokipojat, or IPK, and the arrival of North American or European imports whose skill level relative to the league can be difficult for bookmakers to accurately project. Over/under season point totals, when offered, tend to shift most sharply after preseason tournament results in September reveal early-season form.

Vig patterns in Mestis betting follow a recognizable arc. Preseason and early-season lines tend to carry wider margins — often 6-8% on match moneylines — because bookmakers hedge against low-confidence models for a league with high roster churn. As the season progresses and results data accumulates, margins can tighten to the 4-5% range on higher-profile matchups, particularly rivalry games or contests with playoff positioning implications. Playoff lines occasionally tighten further due to increased betting volume, but the best value window historically sits in October and November, when the market has posted sharpened lines but hasn't yet fully absorbed the impact of mid-season Liiga roster cuts that send quality players down to Mestis clubs.

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.
