LowVig.ag leads with 2.93% vig (A), followed by Pinnacle at 3.91%. The spread between #1 and #19 is 4.17% — book choice matters significantly for NFL Preseason.

NFL preseason betting occupies a unique niche that rewards research-intensive bettors willing to dig deeper than the casual market. With starters often playing limited snaps — sometimes a single series or one quarter — outcomes hinge on the depth of a roster rather than star power. Scoring patterns can be erratic: games may feature long stretches of sloppy play from third- and fourth-string players punctuated by occasional explosive plays. Totals tend to skew lower than regular-season games, and point spreads frequently land in tighter ranges since talent gaps narrow when backups dominate the action. Market depth is thinner than the regular season, with fewer prop options and lower betting limits at most sportsbooks.

Vig on NFL preseason lines tends to run wider than during the regular season. Sportsbooks face less sharp action and lower overall handle, which reduces their incentive to sharpen lines aggressively. The inherent unpredictability — coaches revealing little about their snap-count plans, unknown roster cuts happening mid-week — gives books additional reason to pad margins. It's not uncommon to see -115/-105 splits or even -110/-110 lines that mask an inflated total margin, particularly on totals and lesser-watched matchups. Comparing vig across books during preseason is arguably more valuable than at any other point in the NFL calendar, since the spread between the sharpest and softest prices can be significant.

The preseason typically runs from early August through late August, with three games per team since the schedule was trimmed from four in 2021. Lines tend to be loosest for the first week of games, when information about depth charts and playing-time plans is scarcest. By the second and third games, as teams reveal rotational patterns and cut-down deadlines approach, sharper bettors begin identifying edges and books tighten accordingly. Key factors to monitor include coaching staff tendencies — some coaches play starters extensively in the final preseason game while others rest them entirely — along with roster battles at quarterback, offensive line injuries that reshape blocking schemes, and whether teams are installing new systems under first-year coordinators, which often correlates with sluggish early offensive output.

Frequently Asked Questions

Which sportsbook has the lowest vig for NFL Preseason?

LowVig.ag currently has the lowest average vig for NFL Preseason at 2.93%, earning a grade of A.

How do sportsbook odds compare for NFL Preseason?

We compare 19 sportsbooks for NFL Preseason. The vig ranges from 2.93% (LowVig.ag) to 7.10% (Fliff).

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.
