NFL spread betting requires a chosen team to win by more than a specified margin (for favorites) or lose by less than that margin (for underdogs). Unlike NBA spreads, which routinely land on various numbers, NFL spreads cluster around key numbers — particularly 3 and 7, reflecting the sport's scoring structure of field goals and touchdowns. This makes the difference between getting +2.5 versus +3 genuinely significant in terms of win rate, far more so than a half-point shift in a basketball line.

Sharp bettors focus heavily on line movement and timing in the NFL spread market. Lines released early in the week often shift as injury reports, weather forecasts, and public betting patterns develop, creating windows of value for those tracking movements closely. Home-field advantage, short-week fatigue in Thursday games, and divisional familiarity are all factors that can create mispricings. Regarding vig, NFL spreads are among the most competitive markets in all of sports betting — standard juice sits at -110 per side, but reduced-vig books regularly offer -105 or better. Even small vig differences matter enormously over a full season, making side-by-side comparison of pricing across books essential for long-term profitability.

Frequently Asked Questions

Which sportsbook has the lowest NFL spreads vig?

LowVig.ag currently has the lowest vig at 2.44%, earning a grade of A.

Why is NFL vig typically lower than other sports?

NFL games attract massive betting volume, which forces sportsbooks to compete on price. Higher liquidity lets books operate on thinner margins. The result is that NFL moneylines, spreads, and totals usually carry some of the lowest vig in all of sports betting.

What markets are available for NFL betting?

We track three core NFL markets: moneyline (who wins), point spreads (margin of victory), and totals (over/under combined points). Each market has its own vig profile — spreads tend to have the tightest lines because they see the highest volume.

When does NFL season start and end?

The NFL regular season runs from early September through mid-January, with playoffs extending through the Super Bowl in February. Preseason odds typically appear in August. During the off-season (March–August), sportsbooks may post futures but per-game lines are unavailable.

How do NFL spreads affect vig?

NFL point spreads are the most heavily bet market in American sports. This intense competition among both bettors and sportsbooks drives spreads to their most efficient prices. You'll often see NFL spreads at -110/-110 or better at sharp books, translating to vig under 5%.

Does vig change closer to NFL game time?

Yes. Early-week NFL lines often carry higher vig as books manage exposure with limited information. As kickoff approaches and sharp money flows in, lines tighten and vig tends to decrease. Betting closer to game time often means better prices, especially at sharp-friendly books.

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.

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.
