Every NFL bettor has heard that three and seven are the "key numbers," but how much of the folklore survives contact with a full dataset? This study counts the final margin of victory in 7,276 NFL games from the 1999 through 2025 seasons and pairs each result with the point spread and total recorded for that game. The result is a reference table of NFL margin of victory data that writers, students, and bettors can cite, plus a close look at how often spreads push, cover, and miss.
Key Findings: NFL Margin of Victory Data at a Glance
- A margin of exactly 3 points occurred in 15.12% of games (1,100 of 7,276), the most common final margin by a wide gap; 7 points was next at 9.03% (657 games).
- Games decided by 8 points or fewer made up 50.7% of the sample, and the median margin was 8 points (mean 11.54).
- When the favorite was laid exactly 3 points, the game pushed 9.0% of the time; at exactly 7 it pushed 6.5%.
- Overall, 2.68% of all spreads landed exactly on the number, while 1.46% of totals did.
Why Margin of Victory Matters for Understanding Spreads
A point spread is a bet on the distribution of final margins. Because football scores arrive in chunks of 3 (field goal), 6, 7 (touchdown plus extra point), and occasionally 2 or 8, the distribution is lumpy rather than smooth. Some margins are far more likely than their neighbors, and that lumpiness is why sportsbooks price a half-point differently depending on where it sits on the number line. Moving a spread from -2.5 to -3.5 crosses the single most frequent margin in the sport; moving from -4.5 to -5.5 crosses almost nothing.
The point of this article is to measure that lumpiness directly. Third-party coverage has described the effect before: Action Network, for example, reported that a three-point margin occurred in 14.8% of NFL games since the start of the 2003 season and called it "by far the most common margin." Our larger window and full count tables let readers check that claim against a 27-season sample and examine every margin up to 21 points.
Methodology
Data source and sample
We used the public game-level file maintained by the nflverse project (nfldata repository on GitHub), which includes final scores, game type, and the point spread and total line recorded for each game. We kept every completed regular-season and postseason game from the 1999 season through the 2025 season: 6,967 regular-season games, 120 wild-card games, 108 divisional-round games, 54 conference championship games, and 27 Super Bowls, for 7,276 games in all. Games from the in-progress 2026 season were excluded so that every season in the sample is complete.
Definitions
Margin of victory is the absolute difference between the two teams' final scores, so a tie has a margin of 0 (there were 15 in the sample). The spread is the home-team line stored in the dataset; we treat the team laid points as the favorite. A "cover" means the favorite won by more than the spread, a "push" means the favorite won by exactly the spread, and the underdog covers otherwise. Totals are measured the same way against the recorded total line. Percentages are rounded to one or two decimals.
Limitations
The dataset records a single line per game, and we did not independently verify which sportsbook or timestamp it represents. Individual books post different numbers, and a line that was available at one shop may not have been at another. The figures below describe the recorded line, not what any individual bettor could have obtained, and they say nothing about future games. Small samples at rare spreads (for example, only 90 games at exactly -14) carry wide error bands and should be read as descriptive, not predictive.
The Complete Margin-of-Victory Table (1999-2025)
The table below lists every margin from 0 to 21 points. Margins of 22 or more account for the remaining 15.0% of games, with a maximum observed margin of 59 points.
| Margin (points) | Games | Share of all games | Cumulative share |
|---|---|---|---|
| 0 | 15 | 0.21% | 0.2% |
| 1 | 303 | 4.16% | 4.4% |
| 2 | 295 | 4.05% | 8.4% |
| 3 | 1,100 | 15.12% | 23.5% |
| 4 | 355 | 4.88% | 28.4% |
| 5 | 260 | 3.57% | 32.0% |
| 6 | 436 | 5.99% | 38.0% |
| 7 | 657 | 9.03% | 47.0% |
| 8 | 271 | 3.72% | 50.7% |
| 9 | 117 | 1.61% | 52.4% |
| 10 | 401 | 5.51% | 57.9% |
| 11 | 171 | 2.35% | 60.2% |
| 12 | 120 | 1.65% | 61.9% |
| 13 | 201 | 2.76% | 64.6% |
| 14 | 355 | 4.88% | 69.5% |
| 15 | 109 | 1.50% | 71.0% |
| 16 | 154 | 2.12% | 73.1% |
| 17 | 260 | 3.57% | 76.7% |
| 18 | 169 | 2.32% | 79.0% |
| 19 | 86 | 1.18% | 80.2% |
| 20 | 156 | 2.14% | 82.3% |
| 21 | 193 | 2.65% | 85.0% |
What the distribution shows
Three results stand out. First, a margin of 3 is more than 1.6 times as common as the next most frequent margin, 7 (15.12% versus 9.03%). Second, the five margins of 3, 6, 7, 10, and 14 together account for 40.5% of all games, even though they are only five of the roughly 60 margins that occurred. Third, the distribution has pronounced valleys: a margin of 9 (1.61%), 12 (1.65%), 15 (1.50%), and 19 (1.18%) are all rarer than a margin of 1, which happened 4.16% of the time. Two-possession games, where the winning team leads by a touchdown plus a field goal, are common; one-possession games decided by a fraction of a possession are not.
Margins of 14 and 4 occurred with identical frequency in the sample (355 games each, 4.88%), a reminder that two-touchdown finishes are about as common as a field goal plus a safety-sized cushion. Overall, 23.5% of games were decided by 3 points or fewer, 47.0% by 7 or fewer, 73.1% by 16 or fewer, and 17.7% by 21 or more.
How Often Do Spreads Land on the Number?
Because margins cluster, the chance that a game lands exactly on its point spread depends heavily on the spread. Across all 7,276 games, 2.68% pushed against the recorded spread. The table below shows results for the most common spreads in the sample, with the favorite's perspective throughout.
| Closing spread (favorite) | Games | Push rate | Favorite covers | Underdog covers | Favorite wins outright |
|---|---|---|---|---|---|
| -1 | 546 | 1.5% | 49.8% | 48.7% | 51.3% |
| -2.5 | 531 | 0.0% | 47.6% | 52.4% | 52.9% |
| -3 | 1,153 | 9.0% | 43.3% | 47.7% | 58.0% |
| -3.5 | 682 | 0.0% | 49.9% | 50.1% | 63.6% |
| -4 | 342 | 2.3% | 50.3% | 47.4% | 66.1% |
| -6 | 354 | 3.7% | 47.7% | 48.6% | 68.1% |
| -6.5 | 340 | 0.0% | 46.5% | 53.5% | 71.8% |
| -7 | 491 | 6.5% | 47.0% | 46.4% | 75.6% |
| -7.5 | 291 | 0.0% | 47.8% | 52.2% | 76.3% |
| -10 | 213 | 6.6% | 41.8% | 51.6% | 81.2% |
| -14 | 90 | 4.4% | 42.2% | 53.3% | 87.8% |
The 3-point spread
A line of exactly 3 produced a push in 9.0% of its 1,153 games. The favorite covered 43.3% of the time and the underdog covered 47.7%. Because pushes return the stake, bettors usually compare the cover rates among decided bets: the underdog won 47.7 out of every 91.0 decided games, or 52.4%, which is almost exactly the 52.38% break-even rate for standard -110 pricing. Because the outcomes sit this close to break-even, the pricing attached to a line of 3 matters as much as the number itself.
The neighboring numbers behave differently. At -2.5 the favorite covered 47.6% of 531 games, and at -3.5 it covered 49.9% of 682. The gap between "favorite wins by 3 or fewer" and "favorite wins by 4 or more" is where the market concentrates its pricing.
The 7-point spread
A line of exactly 7 pushed 6.5% of the time across 491 games, with a near-even split among decided games (favorite 47.0%, underdog 46.4%). Seven is the second most common margin overall, but it is less dominant than three, so the half-point premium on -7 is smaller than on -3. At -6.5 the favorite covered 46.5% of 340 games, while at -7.5 it covered 47.8% of 291.
Spread ranges
Grouping spreads into ranges smooths out the noise at individual numbers.
| Spread range | Games | Push rate | Favorite covers | Underdog covers | Favorite wins outright |
|---|---|---|---|---|---|
| 0.5 to 3 | 2,603 | 4.5% | 46.7% | 48.9% | 55.1% |
| 3.5 to 6.5 | 2,440 | 0.9% | 48.6% | 50.5% | 66.6% |
| 7 to 9.5 | 1,299 | 2.5% | 47.2% | 50.3% | 75.8% |
| 10 to 13.5 | 688 | 2.5% | 46.9% | 50.6% | 82.8% |
| 14 or more | 215 | 3.7% | 45.6% | 50.7% | 91.2% |
Favorites won outright 55.1% of the time when laid up to 3 points, 66.6% between 3.5 and 6.5, 75.8% between 7 and 9.5, 82.8% between 10 and 13.5, and 91.2% when laid 14 or more. In every range the underdog covered slightly more often than the favorite, which is consistent with a market that shades its numbers slightly toward popular favorites; we make no claim that this edge is large enough or stable enough to be exploited after pricing. The favorite cover rate also sits below 50% in every range, with the lowest value (45.6%) among the biggest favorites, though that group has only 215 games.
Has the Distribution Changed Over Time?
The league's rules, scoring, and extra-point distance have changed since 1999, so it is fair to ask whether the margin distribution has changed with them. The table below splits the sample into four eras.
| Era | Games | Decided by exactly 3 | Decided by exactly 7 | Average total points | Average margin |
|---|---|---|---|---|---|
| 1999-2005 | 1,845 | 16.5% | 9.4% | 41.9 | 11.57 |
| 2006-2012 | 1,869 | 14.9% | 9.7% | 43.8 | 12.09 |
| 2013-2019 | 1,869 | 13.9% | 9.1% | 45.6 | 11.39 |
| 2020-2025 | 1,693 | 15.2% | 7.7% | 45.9 | 11.09 |
The share of games decided by exactly 3 fell from 16.5% in 1999-2005 to 13.9% in 2013-2019 before recovering to 15.2% in 2020-2025. The share decided by exactly 7 slid from 9.4% to 7.7% across the same stretch. Average total points rose from 41.9 to 45.9 per game, yet the average margin barely moved (11.57 in the first era versus 11.09 in the last). More scoring did not make games more lopsided; it mostly added points to both sides. Action Network also noted that margins of 5 and 6 have become more common in recent years, which fits the modest decline in 7s here.
In single seasons, the share of games decided by exactly 3 ranged from 10.5% (2019) to 16.9% (2018 and 2022) in the 2015-2025 window, so a single season can differ meaningfully from the long-run 15.1% figure. Treat any one-year "key number" claim with caution.
Totals: How Often Does the Over/Under Push?
Across the same 7,276 games the average combined score was 44.3 points. Games went over the recorded total 48.7% of the time and under it 49.8% of the time, with the remaining 1.46% landing exactly on the total. Totals have their own key numbers because scores combine many scoring plays, but the distribution is much smoother than margin of victory: no single final total in our sample represented more than about 4% of games. Totals pushes are therefore rarer than spread pushes on the main numbers, and half-point moves in totals are generally worth less than half-point moves through 3 on a spread.
Home-Field Context
Home teams won 56.3% of all games in the sample, including the 15 ties in the denominator. That figure is an important reminder that spreads are built partly on home-field adjustments, and that the margin distributions above blend home and road favorites together.
How to Use This Data
For bettors and analysts
Margin tables are most useful for understanding why a half-point is not a half-point. If you are comparing prices across sportsbooks, the exact margin frequencies above explain why a book might move a line from -3 to -2.5 but charge for it. Our sports betting hub and the US sportsbook guide explain how to compare odds across operators, and our betting basics guide covers how pushes are settled. If you shop for sign-up offers, the best sportsbook promos page lists current terms, but no promotion changes the underlying probabilities described here.
For journalists and researchers
Every figure in this article can be reproduced from the nflverse public game file using the definitions in the methodology section. If you cite a margin frequency, please state the sample window (1999-2025) and the number of games (7,276), since results shift by one to two percentage points depending on the seasons included.
Frequently Asked Questions
What is the most common margin of victory in the NFL?
Three points. In our 7,276-game sample from 1999 through 2025, 1,100 games (15.12%) were decided by exactly a field goal. Seven points is second at 9.03%.
How often does an NFL game land exactly on the point spread?
About 2.68% of the time overall. The rate rises sharply on key numbers: 9.0% at a spread of 3, 6.5% at 7, 6.6% at 10, and 3.7% at 6.
Are favorites or underdogs more likely to cover?
In this sample the underdog covered slightly more often than the favorite in every spread range, and the favorite cover rate was between 45.6% and 48.6% across ranges. The differences are small and ignore pricing, so they should not be read as a guaranteed edge.
Has the share of three-point games changed?
It fell from 16.5% in 1999-2005 to 13.9% in 2013-2019 and recovered to 15.2% in 2020-2025. Single-season values ranged from 10.5% to 16.9% between 2015 and 2025.
How often do NFL totals push?
Only 1.46% of games landed exactly on the recorded total, compared with 2.68% for spreads. Overs hit 48.7% of the time and unders 49.8%.
