How to Read Sports Betting Odds: Moneyline, Spread & Totals Explained
-110. +270. -5.5. Over 224.5. If you've ever opened a sportsbook app and felt like you were reading another language, you're not alone. Learning how to read sports betting odds is the first skill every bettor needs, and it's easier than it looks. Once you understand what the numbers are telling you, every game on the board makes more sense.
This guide breaks down moneylines, point spreads, totals and implied probability in plain English, with real examples you can use tonight.
How to Read Sports Betting Odds: American Odds Basics
Most US sportsbooks use American odds, which are shown as a number with a plus or minus sign. Here's the simple version:
A minus sign (-) marks the favorite. The number shows how much you must bet to win $100 in profit. At -200, you bet $200 to win $100.
A plus sign (+) marks the underdog. The number shows how much you win on a $100 bet. At +150, a $100 bet wins $150 in profit.
The bigger the number, the bigger the gap. A +900 long shot is far less likely to hit than a +150 underdog, but pays more.
You can bet any amount, of course. A $10 bet at +150 profits $15, and a $10 bet at -200 profits $5. The math scales with your stake.
Moneyline Betting Explained
The moneyline is the simplest bet in sports. You're picking who wins the game, nothing more. Say a game has Team A at -200 and Team B at +170 (a hypothetical example). Team A is the favorite, so you risk more to win less. Team B is the underdog, so a win pays more than you put down.
Moneylines are popular in sports with lower scoring like baseball and hockey, where the margin of victory matters less. If you're curious how this works in baseball, our beginner's guide to MLB betting odds goes deeper.
Point Spread Betting Explained
The point spread levels the playing field. Instead of picking a winner, you're picking whether a team wins by more or less than a set margin. On NBA opening night this season, the Knicks were roughly 5.5-point favorites over the Sixers at FanDuel. Here's what that means:
Knicks -5.5: New York has to win by 6 or more for the bet to cash.
Sixers +5.5: Philadelphia can win outright or lose by 5 or fewer and the bet still cashes.
Spreads usually come with a price of -110 on both sides. The half-point (the .5) is there to avoid a tie, which sportsbooks call a push. When a spread is a whole number and the game lands on it, your stake is returned.
Over/Under Totals Explained
A total is the sportsbook's projection for the combined score of both teams. You're betting on whether the real score lands over or under that number. If an NBA game has a total of 224.5 (hypothetical), the over needs 225 or more combined points and the under needs 224 or fewer.
Totals reward bettors who pay attention to pace, injuries and matchups. A star ruled out late can move a total by several points, which is why checking the injury report before you bet is a habit worth building.
Implied Probability: The Number Behind the Number
This is the part that separates casual bettors from smart ones. Every set of odds carries an implied probability, which is the chance the sportsbook's price is saying an outcome will happen. The formulas are simple:
Negative odds: odds (without the minus) divided by odds plus 100. At -200, that's 200 / 300 = 66.7%.
Positive odds: 100 divided by odds plus 100. At +150, that's 100 / 250 = 40.0%. At +270, it's 100 / 370 = 27.0%.
Now take that standard -110 spread price. It converts to about 52.4%, which means you need to win roughly 52.4% of your bets just to break even. Put both sides of a -110 line together and you get about 104.8%. That extra 4.8% is the sportsbook's built-in margin, often called the vig or juice. Knowing it exists is the first step toward beating it.
Common Mistakes When Reading Sports Betting Odds
Ignoring the vig. A bet can feel like a coin flip and still cost you money over time.
Chasing big parlays. Every leg must win, so the risk compounds with every pick you add.
Not shopping lines. The same spread can sit at -105 at one book and -115 at another. Small gaps add up.
Betting without a plan. Pick a unit size and stick to it. Our bankroll management guide shows you how.
Betting on your feelings. Loyalty is great in the stands. At the window, the price is what matters.

The Bigger Picture: Smarter Fans, Stronger Betting Culture
The more fans understand odds, the more engaged they become. They follow line movement, compare prices and talk about the numbers right alongside the game. Sports betting platforms rely on engaged audiences like this, and as sports betting continues to grow, content-driven exposure becomes key. Media platforms like Remix Sports Media help connect betting brands with real fans who want to learn, not just click.
Conclusion
Reading odds comes down to a few building blocks: American odds tell you the price, the moneyline picks the winner, the spread sets the margin, the total sets the score, and implied probability tells you what the market believes. Learn those five and you'll never look at a sportsbook the same way again. Take your time, start small, and treat every bet as entertainment first.
