The American Hockey League occupies a fascinating niche in the betting landscape. As the NHL's primary developmental league, rosters are in constant flux — players get called up, sent down, or reassigned on a near-daily basis, creating a level of lineup volatility that dwarfs what bettors encounter in major professional leagues. Scoring tends to run higher than the NHL, with goaltending less consistent and defensive systems less refined, which makes totals markets particularly interesting. However, market depth is thin compared to the NHL: fewer sportsbooks post AHL lines, and those that do often limit betting volume, meaning sharp action can move lines quickly and dramatically.
Vig on AHL markets is typically wider than what bettors find on NHL games, and it's not close. While a standard NHL moneyline might carry a combined vig of 4-5%, AHL lines frequently sit in the 6-10% range or higher, depending on the book. This reflects the lower betting volume, reduced public interest, and the added risk sportsbooks assume when setting lines on a league with less predictable outcomes. Because fewer books post AHL odds, competition among operators is weaker, giving them less incentive to sharpen their margins. This makes vig comparison especially valuable — the spread between the best and worst-priced books on a given AHL game can be substantial.
The AHL regular season runs from October through mid-April, with the Calder Cup Playoffs extending into June. Early-season lines tend to carry the widest margins as books navigate roster uncertainty from NHL training camps and early-season reassignments. Vig generally tightens slightly as the season progresses and rosters stabilize, particularly during the playoff push when public interest and handle increase. Bettors should pay close attention to NHL transaction wires, as a single call-up of a starting goaltender or top-line forward can completely reshape a team's outlook overnight. Home-ice advantage also plays a larger role than in the NHL — travel schedules are grueling, arenas vary wildly in size, and some teams post significantly stronger home records, making venue a meaningful factor in handicapping.

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 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.
