How NFL Point Spreads Are Calculated: Factors that Influence the Line
NFL point spreads are a fundamental part of sports betting, providing a way to even out matchups between teams of differing strengths. Whether you’re new to sports betting or a seasoned bettor, understanding how these point spreads are calculated can give you a competitive edge.
Oddsmakers don’t pull these numbers out of thin air; various factors come into play when determining the line. From team performance and injuries to public betting trends, these elements shape the spread and ultimately influence how bets are placed. Below, let’s dive into the key factors influencing NFL point spreads and their calculation.
The Basics of NFL Point Spreads
At its core, an NFL point spread is a way to level the playing field between two teams of varying strengths, making the bet more competitive. Oddsmakers assign a point spread, which is essentially a handicap that the favored team must cover.
For example, if a team is favored by -7, they need to win the game by more than 7 points for a bet on them to win. On the other hand, the underdog can lose by up to 6 points or win outright for their bet to pay off.
This system makes betting more interesting, as it’s not just about which team wins but by how much. These point spreads shift each week based on team performance, injuries, and other factors.

Team Strength and Performance
One of the most significant influences on point spreads is each team’s perceived strength. Oddsmakers assess various metrics, including win-loss records, offensive and defensive stats, and recent performance. Teams with strong offenses or elite defenses are often favored, and their spreads reflect this advantage.
In addition to overall strength, recent performance plays a vital role. A winning streak with convincing victories may increase their spread, while a team with consecutive losses may see a more favorable line for bettors.
Home-Field Advantage
Home-field advantage is a well-known factor that often influences NFL point spreads. Traditionally, it has been said that home-field advantage is worth about three points on the spread. For example, if the Dallas Cowboys are favored by 3 points at home against the Miami Dolphins, it suggests the teams would be evenly matched on a neutral field.
However, in recent years, the significance of home-field advantage has been diminishing. Since 2007, the average point spread for home teams has gradually decreased. In 2019, home teams had a particularly poor record against the spread, going 104-137-10 (43.2%), the lowest winning percentage in NFL history.
Several factors may be contributing to this shift. The introduction of instant replay and expanded review systems has made officiating more neutral, reducing the benefit home teams used to enjoy.
Additionally, advances in travel comfort, such as private jets and luxury buses, as well as improved sleep science and player recovery techniques, have made it easier for teams to perform well on the road. As a result, home-field advantage has less impact on NFL point spreads than it once did.
Injuries and Player Availability
Injuries are perhaps the most dynamic factor affecting NFL point spreads. The absence of key players, such as a starting quarterback, running back, or defensive star, can significantly shift the line. If a star player is ruled out before game day, the point spread may quickly adjust to reflect the diminished capability of the affected team.
In addition, suspensions and player availability due to health protocols can also sway the point spread. Bettors must stay up-to-date on team news to make well-informed decisions.
Betting Public and Market Movements
One key factor that affects NFL point spreads is the influence of public betting and market movements. When the general public places many bets on a particular team, sportsbooks often adjust the point spread to balance the action.
This minimizes the sportsbook’s risk and encourages betting on the opposing team. For example, if the public heavily backs a favored team, the point spread might shift to make the underdog more appealing, thus evening out the betting action.
Additionally, sharp bettors, who are typically more knowledgeable and place larger bets, can impact the line. If sharp money goes against public sentiment, it can cause significant shifts in the spread.
Public bias often favors popular teams or high-profile games, creating value opportunities for contrarian bettors who capitalize on inflated lines. Ultimately, betting market movements, driven by public action and sharp money, play a critical role in calculating NFL point spreads.
Matchup-Specific Factors
Every game presents unique matchups that can influence the spread. Whether a team excels at running the ball or defending against the pass, these specific strengths and weaknesses can affect the point spread.
Oddsmakers analyze how each team’s style of play matches up against their opponent. If a team’s offensive strengths align with their opponent’s defensive weaknesses, the spread may widen in their favor.
Weather is another matchup-specific factor that can impact the spread, especially in outdoor stadiums. High winds, rain, or snow can limit a team’s ability to pass or kick effectively, potentially lowering scoring expectations and affecting the spread. Cold weather, in particular, can favor teams with strong running games and defenses.
Conclusion
NFL point spreads are calculated based on team strength, recent performance, injuries, home-field advantage, and betting market behavior. Understanding these influences and tracking line movements throughout the week helps bettors make more informed decisions and improve their chances of success when wagering on NFL games.
