Betting on NFL football has become a major industry, attracting millions of fans each season who want to profit from their predictions and understanding of the game. Whether you’re a newcomer or someone with experience in sports betting, it’s essential to have a clear grasp of how NFL football betting odds work. These odds not only determine how much you could win but also reflect a vast amount of information about the probabilities of outcomes. Understanding them will give you an edge, improve your decision-making, and help you manage risks effectively.
What Are NFL Betting Odds?
NFL betting odds represent the likelihood of various outcomes in a football game and determine how much a bettor stands to win. These odds are set by sportsbooks and influenced by a range of factors, including statistical data, injuries, betting trends, and even weather conditions. Simply put, they tell you two things:
- How likely it is that an event will happen (as estimated by the bookmaker).
- How much money you can win if your bet is successful.
There are several different types of bets available in the NFL, and each comes with its own odds that you need to understand before placing a wager.
Types of NFL Bets and How the Odds Work
1. Moneyline Bets
The moneyline is the simplest form of betting. You’re picking which team will win the game, regardless of the point difference.
Odds are expressed with either a plus (+) or minus (–) sign:
- +200 means you win $200 for every $100 wagered (underdog)
- –150 means you need to bet $150 to win $100 (favorite)
The plus sign denotes the underdog (expected to lose), and the minus sign indicates the favorite (expected to win). These values are based on $100 increments but scale proportionally.

2. Point Spread Bets
Point spreads aim to level the playing field between two teams by assigning a handicap. Instead of simply picking a winner, you’re betting on whether a team will exceed or fall short of a set numerical margin.
For example:
- New England Patriots –5.5
- Miami Dolphins +5.5
If you bet on the Patriots, they need to win by more than 5.5 points for your bet to be successful. If you bet on the Dolphins, they must either win or lose by fewer than 5.5 points.
Both bets typically carry odds of –110, meaning you bet $110 to win $100. However, this can vary slightly depending on the sportsbook and betting volume.
3. Over/Under (Totals)
Over/Under bets—also known as “totals”—allow bettors to wager on the combined total points scored by both teams in a game. You’re not picking a winner; you’re predicting whether the total points will be over or under a number set by the sportsbook.
Example:
Total Points: 47.5
- If the final score is 28–24, the total is 52 points – the bet goes over.
- If the final score is 21–17, the total is 38 points – the bet goes under.
Odds on totals are usually similar to point spread bets, most commonly –110.
4. Parlay Bets
A parlay bet lets you combine multiple outcomes into a single wager for a much larger payout. To win, all parts of the parlay must hit. This makes parlays riskier but more rewarding.
Example:
- Bears +3.5
- Chiefs –6.5
- Over 48.5 Raiders vs. Chargers
If any leg of that bet fails, the entire bet is lost. But if all three are correct, you enjoy a sizable return relative to your original stake.

5. Prop Bets (Proposition Bets)
Prop bets are wagers on specific events that don’t necessarily relate to the final outcome of a game. These are especially popular for high-profile games like the Super Bowl.
Examples of NFL prop bets:
- Will a quarterback throw for over 300 yards?
- Which player will score the first touchdown?
- Number of field goals made by a certain kicker
Prop bet odds vary widely depending on the specific event and perceived probability.
Understanding and Using American Odds
The NFL primarily uses American odds, where the bettor sees either a negative or positive number. The format is designed to illustrate both risk and reward:
- Positive odds (+200): You win $200 for every $100 wagered
- Negative odds (–150): You must wager $150 to win $100
To convert these odds to implied probability, use the following formulas:
- Negative Odds: –odds / (–odds + 100) * 100
- Positive Odds: 100 / (odds + 100) * 100
This gives you a sense of how likely a particular outcome is according to the sportsbook, which can help you identify value bets (bets where your perceived probability is higher than the sportsbook’s).
Live Betting and Odds Movement
One of the dynamics of modern NFL betting is live betting, where odds are updated during the game. This adds another layer of complexity and opportunity, allowing savvy bettors to take advantage of momentum shifts, injuries, and real-time strategies.
Odds also move in the days leading up to a game based on:
- Injury reports
- Weather conditions
- Betting volume
- Public sentiment
Monitoring line movement is a useful tactic for more experienced bettors, as it may indicate how expert or “sharp” bettors are placing their money.
Choosing the Right Sportsbook
Not all sportsbooks are created equal. Lines and odds can vary slightly between them. By comparing odds across multiple platforms, bettors can ensure they’re getting the best possible value for their wagers.
Key features to look for in a trustworthy sportsbook include:
- Licensing and regulation in your jurisdiction
- Secure platforms with encrypted transactions
- Competitive odds
- Responsive customer service
- Fast and reliable payouts
Never wager at a sportsbook that doesn’t have clearly published rules for how bets are settled and disputes are managed.
Responsible Betting Tips
While betting on NFL games can be exciting and profitable, it’s crucial never to risk more than you can afford to lose. Here are some responsible betting practices to follow:
- Set a budget and stick to it
- Never chase losses
- Keep a record of your bets
- Understand the bet before you place it
- Don’t let emotion dictate your picks
Responsible betting allows you to enjoy the game and possibly profit without risking your financial wellbeing.
Conclusion
Understanding NFL football betting odds is key to becoming a smarter, more strategic bettor. From moneylines and spreads to totals and parlays, each type of bet comes with unique odds that represent potential risk and reward. Whether you’re betting for fun or looking to make consistent profits, knowledge is your most important asset.
Study the odds, recognize value, manage your bankroll, and always bet responsibly. With time and discipline, NFL betting can enhance your appreciation of the game and potentially reward your insight and effort.
