AFL spreads — commonly referred to as line betting — assign a points handicap to level the playing field between two teams. A typical AFL spread might see a favourite listed at -18.5 points, meaning they must win by 19 or more for the bet to pay out. Because AFL is a high-scoring sport with regular totals between 150 and 200 combined points, spreads tend to be wider and more volatile than in sports like basketball or rugby league. A single unanswered run of goals can shift the effective margin by 30+ points in a quarter, which makes late-game variance a constant factor.
The spreads market is most valuable when there's a clear mismatch that head-to-head odds don't reward — backing a dominant side at $1.15 on the moneyline offers little return, but covering a spread can provide close to even-money value. Bettors should monitor weather conditions, travel schedules, and late changes to key midfielders, as these factors disproportionately affect winning margins. Vig on AFL spreads typically sits slightly higher than on head-to-head markets, with bookmakers building in extra margin to account for the difficulty of setting accurate lines in such a volatile scoring environment. Comparing across books is essential, as even half-goal differences in the line can meaningfully shift expected value.

Frequently Asked Questions
Which sportsbook has the lowest AFL spreads vig?
DraftKings currently has the lowest vig at 7.09%, earning a grade of D.
What is AFL and when is it played?
AFL (Australian Football League) is the top professional Australian rules football league. The season runs from March through September, with finals in September-October. AFL is the most popular sport in Australia and attracts significant international betting interest.
How does AFL vig compare to US sports?
AFL vig tends to be moderate — comparable to NBA. Australian bookmakers offer the tightest lines due to local market depth, while US-facing books typically carry wider margins since AFL is a niche sport for their customer base.
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.
