↑ 7-day trend: Average vig has worsened by 0.11 percentage points over the past week (from 7.08% to 7.19%). Odds margins are widening, meaning bettors are getting less value per wager.
Pinnacle leads with 4.78% vig (B), followed by Bovada at 5.18%. The spread between #1 and #13 is 4.25% — book choice matters significantly for Primeira Liga - Portugal.
Portugal's Primeira Liga offers a distinctive betting landscape shaped by a sharp competitive divide. The top three clubs — Benfica, Porto, and Sporting CP — dominate domestically, which means match odds for their fixtures often carry heavy favorites with short prices. Below that tier, however, the league becomes far more unpredictable. Mid-table sides like Braga, Vitória de Guimarães, and Gil Vicente can produce volatile results, creating genuine value opportunities in match result, over/under, and Asian handicap markets. Scoring tends to be moderate, averaging roughly 2.5 goals per match across a season, though fixtures involving the big three against lower-table opponents frequently push over that line. Market depth is solid at major sportsbooks but noticeably thinner than what bettors find in the Premier League or La Liga, particularly for prop and player-level markets.
Vig on Primeira Liga matches varies significantly depending on the fixture's profile. High-profile derbies and matches involving Benfica, Porto, or Sporting typically attract sharper lines and tighter margins — often in the 3–5% range on match result markets — because these games draw more volume and sharper action. For mid-table or relegation-zone clashes, margins tend to widen to 5–7% or more, as bookmakers price in greater uncertainty and lower liquidity. Comparing vig across books becomes especially important for these lesser-followed fixtures, where the spread between the best and worst available prices can be substantial.
The Primeira Liga season runs from mid-August through late May, with a brief winter break around the new year. Odds tend to be most competitive early in the season, when bookmakers are still calibrating their models, and again during the final weeks when title races and relegation battles sharpen public and sharp interest alike. Home advantage is a meaningful factor — Portuguese clubs historically perform well at home, particularly at intimidating grounds like Estádio da Luz and Estádio do Dragão. Bettors should also track European competition schedules closely, as midweek Champions League or Europa League commitments regularly lead to squad rotation that materially impacts domestic results.

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 every hour, on the hour (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 average vig: A+ (under 2%) is exchange-level pricing, A (2–3%) very competitive, B+ (3–4%) above average, B (4–5%) the industry standard, C+ (5–6%) slightly below average, C (6–7%) below average, D (7–8%) high vig, D− (8–10%) very high, F (10%+) predatory.
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, BetAnything). 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 every hour, on the hour (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.
