How to Bet on NFL: American Football Betting for Beginners

⏱ 10 min read

NFL betting is the most popular form of sports wagering in North America, with legal handle exceeding tens of billions of dollars each season across licensed operators. Whether you're watching a Sunday showdown between divisional rivals or tracking a Monday Night Football total, understanding how to bet on American football gives you a structured way to engage with the game — and make more informed decisions at the sportsbook. This guide covers everything a beginner needs to start betting on the NFL with confidence: bet types, how odds work, example walkthroughs, and the strategy principles that separate disciplined bettors from impulsive ones.

NFL betting isn't complicated at its core, but it rewards those who understand the mechanics before placing their first wager. From point spreads to prop bets, each market has its own logic — and each carries a house edge you need to account for. Read this guide in full before depositing, and you'll approach the NFL sportsbook with a sharper eye than most casual bettors do on opening week.

Understanding NFL Betting: The Basics

At its simplest, betting on American football means predicting an outcome and placing a wager on it with a sportsbook. The sportsbook — also called a bookmaker or operator — sets odds that reflect both the probability of an outcome and their built-in margin (the "vig" or "juice"). That margin is typically around 4.5%–5% on standard NFL point spread bets, meaning you need to win roughly 52.4% of your bets just to break even at standard -110 pricing.

The NFL season runs from early September through the Super Bowl in February, giving bettors 18 regular-season weeks plus playoffs. Each week features around 16 games, with most scheduled on Sunday, one on Thursday, and one on Monday. That volume of games means a wide variety of betting markets every single week — and plenty of opportunities to be either selective or overextended, depending on your discipline.

The Three Core NFL Bet Types

Before exploring strategy, you need to know the three foundational markets that underpin NFL betting:

• Point Spread — Betting on the margin of victory
• Moneyline — Betting on the outright winner, no spread involved
• Over/Under (Totals) — Betting on the combined points scored by both teams

Most NFL bettors start with the point spread, as it's the most widely discussed market in American sports media. Mastering these three markets is the foundation of everything else in the NFL betting landscape.

Point Spread Betting Explained

The point spread levels the playing field between mismatched teams. When the Kansas City Chiefs host a weaker opponent, the sportsbook doesn't just offer you Chiefs to win — it forces you to decide whether the Chiefs will win by more than a specified margin. That margin is the spread.

A typical line might read: Kansas City Chiefs -6.5 / Las Vegas Raiders +6.5. Betting the Chiefs at -6.5 means they must win by 7 or more points for your bet to win. Betting the Raiders at +6.5 means they can lose by up to 6 and your bet still wins. The half-point (.5) eliminates the possibility of a push (tie), which would result in your stake being returned.

Standard odds on spread bets are -110 on both sides, meaning you bet £110 to win £100 (or $110 to win $100). This -110 pricing is where the sportsbook's margin lives. Shopping for the best line — a practice known as line-shopping — can make a meaningful difference over a full season; moving from -110 to -105 on a bet reduces your break-even win rate from 52.4% to 51.2%.

What Moves the Line?

Spreads aren't static. They shift based on betting volume (sharp money from professional bettors), injury news, and weather reports. Opening lines are set early in the week — sometimes as early as Sunday evening for the following week's games — and often move significantly by kickoff. Tracking line movement is a key skill for experienced bettors: sharp movement (without an obvious injury catalyst) signals that professional money has identified value.

Moneyline and Over/Under (Totals) Bets

The moneyline is the purest bet in sports: pick who wins, full stop. No spread to worry about. In NFL betting, moneylines are quoted as American odds — a three-digit figure with a plus or minus sign that tells you both the implied probability and the payout structure.

With the moneyline, favourites are priced at negative odds (-220 means you bet £220 to win £100). Underdogs carry positive odds (+185 means you bet £100 to win £185). The greater the favourite, the worse the moneyline value — betting heavy favourites repeatedly is a common way beginners drain their bankrolls despite winning more often than not, because a single underdog loss can wipe out multiple favourite wins.

Over/Under (Totals) Betting

Totals bets ignore the winner entirely. You're simply predicting whether both teams combined will score over or under the posted number. If the line is 48.5 and the final score is 31–24 (55 combined points), the Over wins. Totals are priced at -110 on both sides, just like spreads. Key factors that move totals: starting quarterback matchups, offensive line injuries, weather conditions, and pace-of-play metrics. Wind above 15 mph and temperatures below freezing consistently suppress NFL scoring, making totals one of the more weather-sensitive betting markets in professional sport.

Prop Bets and Parlays

Once you understand the core markets, two additional bet types become relevant: prop bets (short for proposition bets) and parlays. Both are popular with recreational bettors, and both carry caveats worth understanding before you allocate significant bankroll to them.

Prop Bets: Player and Game Propositions

Prop bets focus on individual performances rather than game outcomes. Will Patrick Mahomes throw for over 285.5 passing yards? Will the first score of the game be a touchdown or a field goal? Props add a strong entertainment layer to NFL viewing — but they typically carry a higher vig than spread or totals markets. The house edge on player props often runs 8%–15%, compared to roughly 4.5% on standard spreads. They're not the most efficient markets for serious bettors, but they can be well-suited to smaller, entertainment-focused stakes.

Parlays: High Reward, High House Edge

A parlay combines two or more bets into a single wager. All legs must win for the parlay to pay out. The potential payout grows with each added leg — a 4-team parlay at -110 odds on each leg pays roughly +1149 (about 11.5-to-1). But the mathematically fair payout for four -110 bets all winning is closer to +1320, meaning the sportsbook retains a substantially larger edge on parlays than on single-game bets. Parlays are a legitimate recreational product. They are not a path to consistent profit. Use them sparingly and stake only small amounts relative to your bankroll.

NFL Betting Strategy: Key Principles

Strategy in NFL betting doesn't mean finding a magic system that beats the house — in negative-EV markets like point spreads and totals, no such system exists. What it does mean is making informed decisions, managing your bankroll properly, and identifying spots where your analysis is sharper than the market. The goal is to minimise edge given to the sportsbook and maximise the quality of your decision-making.

Home Field Advantage and Key Numbers in the NFL

Home field advantage in the NFL is worth approximately 2.5–3 points in spread terms historically, though that figure has trended downward in the post-COVID era as crowd effects have moderated. Factor this into your spread analysis. Additionally, the NFL's scoring structure makes certain margins far more common than others. 3 and 7 are the key numbers — field goals and touchdowns-plus-extra-points drive the vast majority of scoring. Buying a half-point to cross from -3 to -2.5, or from +3 to +3.5, has genuine mathematical value and is worth paying a small amount of extra juice for in many situations.

How to Read NFL Odds and Lines

American odds (also called "moneyline odds") are the default format at US sportsbooks, but most international operators also display lines in decimal or fractional format. Understanding all three makes you a more flexible bettor capable of comparing value across different platforms.

The implied probability is the most important number at the sportsbook. To convert American odds to implied probability: for a negative number, divide the absolute value by (absolute value + 100). For -110: 110 ÷ 210 = 52.38%. That's your break-even win rate. If your own assessment of the probability is higher than 52.38%, the bet has positive expected value in your model. If it's lower, the correct decision is to pass.

A full NFL betting line typically shows: the spread with pricing, the total with pricing, and the moneyline for each team. Reading all three simultaneously gives you a complete picture of how the sportsbook has priced the game and where the lines sit relative to your own assessment. NFL betting competence starts with being able to parse a full line in seconds.

Frequently Asked Questions

What is the easiest NFL bet type for a beginner?

The over/under (totals) market is often considered the most accessible starting point for NFL beginners. You don't need to predict the winner — only whether the combined score goes above or below the posted number. It removes the complexity of assessing matchup dynamics and focuses your research on a single question: how many points will these two teams score? That said, totals are not easier to beat than spreads — both carry roughly the same house edge of around 4.5% at standard -110 pricing. "Easier to understand" is not the same as "easier to profit from," and beginners should approach both markets with the same discipline.

How does the point spread work in NFL betting?

The point spread is a handicap applied to the favoured team to create a more balanced betting market. If the San Francisco 49ers are listed at -7 against the Arizona Cardinals, the 49ers must win by 8 or more for a spread bet on them to pay out. The Cardinals at +7 cover if they win outright or lose by 6 or fewer. Both sides of a standard spread bet are priced at -110 (bet £110 to win £100), so the sportsbook earns its margin from the juice regardless of which side attracts more money. Lines shift throughout the week based on betting action and injury news — and tracking those movements is a key skill for more advanced NFL bettors.

What does -110 mean in NFL betting?

-110 is American odds notation meaning you must wager £110 (or $110) to win £100 in profit. It's the standard pricing on both sides of a point spread or totals bet. The extra £10 above the potential profit is the bookmaker's commission — the "vig" or "juice." This pricing gives the sportsbook a mathematical edge of roughly 4.55% per bet. Over a large sample of bets, that edge compounds significantly, which is why consistent profitability in NFL betting requires either exceptional analytical skill, access to better lines through line-shopping, or both.

Can you make money from NFL betting?

A small percentage of bettors do turn a long-term profit from NFL betting — typically through rigorous line-shopping, identifying mispriced markets, and applying strict bankroll discipline over hundreds of bets. However, the vast majority of bettors lose money over time due to the house edge built into every wager. NFL betting should be approached as entertainment with a defined budget, not as an income stream. Even experienced bettors experience extended losing stretches. The honest framing is this: the house edge means the expected return on any bet is negative, and no staking system or strategy eliminates that mathematical reality in negative-EV markets.

What is a parlay bet in NFL betting?

A parlay combines two or more individual bets into a single wager, with all selections needing to win for the ticket to pay out. The appeal is amplified payout: a 3-team parlay at -110 each pays approximately +595 (around 6-to-1). The risk is that one loss voids the entire ticket. Sportsbooks build a larger margin into parlays than into single-game bets — the expected house edge on a 3-team parlay sits around 12–15% versus 4.5–5% on a single spread. Parlays are a legitimate entertainment product and can be enjoyable with small stakes. They should make up only a minor portion of any bettor's weekly action and never be used as a primary vehicle for chasing losses.

How do I read an NFL betting line?

A standard NFL betting line displays three pieces of information: the spread, the moneyline, and the total. For example: "Chiefs -6.5 (-110) / Raiders +6.5 (-110) — Total: 47.5 (-110/-110) — Chiefs ML: -240 / Raiders ML: +200." The spread (-6.5) tells you the handicap applied to the favourite. The number in parentheses (-110) is the price you pay to bet that side. The total (47.5) is the combined scoring line. The ML figures show straight-up win odds. Reading all three simultaneously gives you a complete picture of how the sportsbook has priced the contest — and knowing the implied probabilities behind each number is the foundation of sharp NFL betting.
