The American Hockey League presents a distinct challenge for bettors precisely because it operates in the shadow of the NHL. As the top developmental league, AHL rosters are in constant flux — players shuttle between the NHL and AHL on a weekly basis, and a single call-up or reassignment can dramatically shift a team's competitive profile overnight. Scoring tends to run higher than in the NHL, with less disciplined defensive structures and more volatile goaltending performances. This creates wider outcome variance on any given night, which can work in a sharp bettor's favor when the lines don't fully account for roster movement. Market depth is limited compared to major leagues; moneylines and puck lines are generally available, but prop markets and live betting options are sparse.
Vig on AHL lines tends to run noticeably wider than what bettors encounter in the NHL. The reason is straightforward: lower betting volume means sportsbooks face more risk from informed bettors and less natural balancing of action on both sides. Books compensate by building in larger margins, often pushing combined moneyline overround into the 8-12% range or higher, compared to the 4-6% typical of NHL games. Not all books price AHL the same way, though, which makes comparing vig across sportsbooks particularly valuable in this market. The spread between the sharpest and softest lines on a given AHL game can be significant.
The AHL regular season runs from October through mid-April, with the Calder Cup Playoffs extending into June. Early-season lines are often the softest, as books and bettors alike are still calibrating rosters after training camp cuts. Midseason tends to see the most roster volatility due to NHL injuries and trades, creating pricing inefficiencies for those tracking transactions closely. Playoff lines generally tighten as volume increases and rosters stabilize. Home-ice advantage carries meaningful weight in the AHL — travel schedules are grueling, arenas vary widely in size and atmosphere, and some teams post dramatically different home and road records. Monitoring daily roster moves through official AHL transaction reports is arguably the single most important edge a bettor can maintain in this league.

Frequently Asked Questions
Which sportsbook has the lowest AHL vig?
theScore Bet (ESPN Bet) currently has the lowest vig at 6.23%, 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.
