The American Hockey League sits in a unique space for bettors — it's the highest level of minor league hockey in North America, serving as the primary development league for the NHL, yet it receives a fraction of the betting attention. The AHL season typically runs from October through April, with Calder Cup playoffs extending into June. Scoring tends to run higher than the NHL, with more volatile outcomes driven by inconsistent goaltending, frequent roster turnover, and younger skaters still refining their defensive positioning. This volatility creates both opportunity and risk: games are harder to model, but the market is also less efficient because oddsmakers and sharp bettors devote fewer resources to it.
Vig on AHL lines is generally wider than what bettors encounter in the NHL. Because betting volume is lower and the market attracts less sharp action, sportsbooks build in more margin to protect themselves against the uncertainty. It's not uncommon to see moneyline vig in the 7-10% range, compared to the 3-5% that's standard on major NHL matchups. Puckline and totals markets, when offered, can carry even steeper margins. The number of books offering AHL lines is also more limited, which reduces competition and keeps spreads between the best and worst vig wider than in major leagues.
Several factors make AHL odds particularly fluid. NHL call-ups and send-downs can transform a roster overnight — a team losing its starting goaltender or top-line forward to the parent club mid-week can shift a line dramatically, and bettors who track transaction wires closely hold a genuine edge. Home-ice advantage tends to be more pronounced than in the NHL, partly due to grueling travel schedules that include long bus trips through smaller markets. Early in the season, when rosters are still settling after NHL training camps, lines tend to be softest. As the season progresses and books accumulate more data, odds tighten modestly, though the vig rarely approaches major-league levels. Playoff lines occasionally sharpen as public interest ticks up, making that window worth monitoring for improved margins.

Frequently Asked Questions
Which sportsbook has the lowest AHL vig?
betPARX currently has the lowest vig at 5.34%, earning a grade of C+.
What is the AHL?
The AHL (American Hockey League) is the primary development league for the NHL. It runs from October through June, with all 32 teams affiliated with NHL franchises. AHL vig is typically higher than NHL because betting volume is significantly lower, but sharp books still offer reasonable prices.
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.
