What Is Point Spread Betting?

Point spread betting is the most popular way to wager on NFL and NBA games in the United States. Instead of simply picking which team wins, you’re betting on whether a team wins or loses by a specific margin of points. That margin is called the point spread, and it’s set by oddsmakers to create a level playing field between two unevenly matched teams.

Here’s how the notation works. When you see Chiefs -6.5 vs. Raiders +6.5, the minus sign (-) means the Chiefs are the favorite, expected to win the game. The plus sign (+) means the Raiders are the underdog, expected to lose. The number (6.5) is the spread itself, meaning the Chiefs must win by 7 or more points for a bet on them to win.

Two key terms you’ll hear constantly: covering the spread means your team beat the spread requirement. If you bet the Chiefs -6.5 and they win 31-21 (a 10-point victory), they covered. If they win 27-24 (a 3-point victory), they did not cover. ATS stands for against the spread, a shorthand for tracking how a team performs relative to the spread rather than just wins and losses.

Here’s a quick example broken down in a table so you can see exactly how outcomes are graded:

That last row is important. A team can lose the game outright and still win your bet, as long as they keep the final margin within the spread. This is what makes spread betting more nuanced than a simple win-or-lose wager.

How Point Spreads Actually Work

Oddsmakers at sportsbooks don’t flip a coin to set the spread. They use a combination of power ratings (numerical team strength rankings), injury reports, weather forecasts, and historical data to establish an opening line. The goal is not to predict the exact final score but to set a number that splits bettor opinion roughly 50/50 on each side.

When you place a spread bet, you’ll almost always see the odds listed as -110 on both sides. That number represents the vig (short for vigorish), also called the juice. The vig is the sportsbook’s commission for accepting your bet. At -110, you must risk $110 to win $100. If the book takes in balanced action on both sides, it collects the losing side’s money and pays the winning side, keeping the difference as profit. That built-in edge is how sportsbooks stay in business.

Now let’s look at an NBA example. The Lakers open as -5.5 favorites against the Clippers. By tip-off, the line has moved to Lakers -7. What happened? Sharp bettors (professionals who move markets) may have hammered the Lakers early. Or a key Clippers injury was announced. Line movement reflects the combined weight of new information and betting volume. Watching how a line moves from open to close tells you a lot about where the smart money is going.

Whole-number spreads create the possibility of a push. If the Lakers are -6 and win by exactly 6, neither side wins the bet and all stakes are refunded. To eliminate pushes, books frequently use half-point spreads like -6.5. You cannot win by half a point in basketball, so one side always wins the bet. This matters more in the NFL, where margins of 3 and 7 are extremely common.

The spread is also not static after it opens. Books adjust lines constantly based on the flow of bets coming in and breaking news. A starting quarterback ruled out on Saturday morning can shift an NFL spread by 3 to 7 points in minutes. Checking the current line right before you place your bet, rather than relying on what you saw earlier in the week, is a basic discipline every bettor should practice.

How to Bet the Point Spread: Step by Step

Placing a spread bet for the first time is straightforward once you know where to look and what to tap. Here’s a clear walkthrough of the entire process from opening the app to confirming your ticket.

1. 01

   Choose a Licensed Sportsbook

   Start with a legal, regulated sportsbook operating in your state. Options like DraftKings, FanDuel, BetMGM, and Caesars are all licensed in most legal betting states. Create your account, verify your identity, and make a deposit using a debit card, PayPal, or bank transfer. Using a licensed book protects your funds and gives you access to legal customer support.

2. 02

   Find the Game and Locate the Spread

   Open the app or website and navigate to the NFL or NBA section. Games are usually listed in a three-column format showing the spread, moneyline, and over/under side by side. The spread column will show something like Chiefs -6.5 (-110) on top and Raiders +6.5 (-110) below. That -110 is the juice on each side.

3. 03

   Decide Favorite or Underdog

   This is the core decision. Do you think the Chiefs will win by 7 or more? Tap their line. Do you think the Raiders will stay within 6 points (win or lose close)? Tap the Raiders line. The bet slip will auto-populate with the spread and odds you selected. Double-check that the correct team and spread number appear before moving forward.

4. 04

   Enter Your Wager Amount

   In the bet slip, type the dollar amount you want to risk. The app will automatically calculate your potential payout. At -110, a $55 bet wins $50 in profit, returning $105 total (your $55 stake plus $50 profit). Start small while you’re learning. A $10 to $25 wager per game is a reasonable range for a beginner.

5. 05

   Confirm and Track the Result

   Hit the “Place Bet” or “Submit” button. You’ll receive a confirmation with a bet ID number. Write it down or screenshot it. After the game ends, your account balance updates automatically within a few minutes. Winning bets are credited as stake plus profit. Losing bets show as settled on your bet history.

One more practical note: sportsbook interfaces vary slightly by platform, but the core layout is nearly identical across the major operators. If you can’t find the spread column, look for a toggle labeled “spread” or “ATS” near the top of the game listings. Most apps default to showing spreads as the primary betting market, so it’s usually the first thing you see.

Calculating Your Payout on a Spread Bet

Understanding how much you actually win on a spread bet starts with the standard juice of -110. At -110, you risk $110 to profit $100. Your total return on a winning bet is $210 ($110 stake returned plus $100 profit). The formula to calculate profit at any odds is straightforward: divide 100 by the odds number (ignoring the minus sign), then multiply by your stake.

Here are two worked examples so the math is concrete:

In the NFL example, you bet $110 on the Chiefs -6.5. They win by 10. Your profit is $100 and your ticket settles for $210 total. In the NBA example, you bet $55 on the Lakers -5.5. They win by 8. Your profit is $50 and your total return is $105. The ratio is the same. For every $1.10 you risk at -110, you win $1.00 in profit.

You’ll also see lines priced at -115 on one side and -105 on the other. This happens when books shade a line toward the popular side. If 75% of bettors are on the Cowboys -3, the book may move the juice to Cowboys -3 (-115) to discourage further action without changing the spread number itself. Always factor the juice into your expected value, not just the spread.

To run your own numbers quickly, check the sports betting calculators and tools available on this site. You can plug in any odds and stake to get an instant payout, break-even percentage, and implied probability. This is especially useful when comparing -110 lines to -105 or -115 lines before placing your bet.

NFL vs. NBA Spread Betting: Key Differences

Both leagues use the same spread betting mechanics, but they play very differently from a handicapping standpoint. Knowing those differences makes you a smarter bettor in each sport rather than applying one-size-fits-all thinking.

In the NFL, spreads typically range from 1 to 17 points, with the vast majority of games falling between 2.5 and 10. The key numbers in football are 3 and 7, because those reflect a field goal and a touchdown plus an extra point. Historical data shows roughly 15% of NFL games end with a 3-point margin and about 9% end at 7. Buying or selling a half-point through 3 or 7 is a legitimate strategic consideration. The NFL also plays just one game per week per team, meaning oddsmakers have more time to set precise lines and bettors have more time to research.

The NBA operates on a much faster schedule. Teams play 82 regular-season games, often on back-to-back nights, and spreads can reach 15 or more points in lopsided matchups. Line movement is quicker and sharper because new information, especially late injury reports, hits within hours of tip-off. A star player listed as questionable at noon can be ruled out by 6 p.m., swinging a spread by 4 to 6 points.

ATS records in the NBA are publicly tracked and reset every season, making recent form more relevant than multi-year history in most cases. Several sports analytics sites publish real-time ATS records by team, rest advantage, and opponent strength. For NFL spread betting, trends run across a longer stretch because of the shorter schedule. For deeper NBA research and current lines, check out the NBA betting hub for up-to-date analysis and ATS tracking.

ATS Betting Strategies That Actually Help

There’s no strategy that wins every time, but there are approaches that sharpen your edge over the long run. The five below are all accessible to a casual bettor and grounded in how real betting markets behave.

1. Fade the Public

Sportsbooks track the percentage of bets (by count) and money (by dollar amount) on each side. When 75% or more of the public is on one team, the book often shades the line to protect itself. Fading the public means betting the side with less public support. It doesn’t work every time, but over hundreds of games, public teams tend to be slightly overpriced because the public overvalues popular teams, home favorites, and recent hot streaks.

2. Buy Key Numbers in the NFL

If a spread sits at Chiefs -2.5 and you can get it at -2 by moving to a different sportsbook, you’ve bought a key number. More importantly, if the spread is a team -3, paying a slightly higher price at -2.5 may be worth it because it prevents a push on a 3-point margin. The margins of 3 and 7 appear far more often than any other number in NFL final scores, so positioning yourself on the right side of those numbers has documented value over a full season.

3. Track ATS Records and Situational Trends

Not all ATS records are created equal. A team that is 8-3 ATS but 6 of those covers came against weak defenses as a home favorite means less than a team that is 6-5 ATS but consistently covers as a road underdog. Look for situational patterns: teams off a blowout loss, divisional rematches, and teams with a three-game win streak tend to generate statistically interesting ATS splits that oddsmakers sometimes underweight in early-week lines.

4. Line Shop for the Best Spread

This is the single highest-ROI habit for any bettor. Having accounts at two or three sportsbooks and checking the spread at each before betting takes about 60 seconds. Over a full NFL season, winning a half-point more on 40 games can realistically mean the difference between a losing record and a break-even or winning one. Visit the NFL predictions and ATS analysis section for spread comparisons across current games.

5. The 1/3 – 2/4 Teaser Strategy

This strategy is best used selectively, not on every two-team teaser available. The edge exists specifically when both legs cross through a key number. Teasers that don’t cross 3 or 7 don’t carry the same mathematical justification.

Common Point Spread Betting Mistakes to Avoid

Most losing bettors don’t lose because their instincts are bad. They lose because of repeatable, avoidable habits. Here are the five most common spread betting mistakes and a direct fix for each.

Mistake 1: Betting too many games. Spreading your bankroll across 10 or 12 games every Sunday dilutes your edge and inflates your variance. The fix: limit yourself to 3 to 5 games per week where you have a specific, well-researched reason to bet.

Mistake 2: Ignoring line movement and the closing line. The line at kick-off reflects the most current and informed view of the market. If you bet a team at -3 early in the week and the line closes at -5, you got the best of it. If it closes at -1, the market disagrees with you and the sharps moved it away from your position. Tracking closing line value is a discipline that separates consistent bettors from casual losers. The fix: note where the line was when you bet and where it closed, and start tracking whether you’re consistently getting the better or worse number.

Mistake 3: Chasing losses by doubling down. If you lose three bets in a row and respond by tripling your next wager to “get even,” you’re no longer making analytical decisions. The fix: set a flat unit size before the season starts and never deviate from it based on recent results.

Mistake 4: Only betting favorites. Heavy favorites at -8 or more cover at a lower rate than their win rate implies because oddsmakers price them accurately, and the public inflates their price further. The fix: actively evaluate underdogs on every game and look for spots where the public has inflated the favorite beyond their true probability.

Mistake 5: Not shopping for the best line. Taking the first number you see at one sportsbook when another book offers a full point better is leaving money on the table. The fix: open accounts at two or three legal sportsbooks and spend 60 seconds comparing lines before placing any bet.
