“Wait, why does this NFL team have a -235 next to its name? What’s with New England Patriots (-15) vs. Miami Dolphins (+15)? Help! HEEEELPPPP!”
If that sounds like you, we’re here to assist you. If you’ve stared at a board at a sportsbook or just seen spreads and moneylines on the Internet and been utterly confused, don’t worry. It’s not just you. Those numbers can be confounding.
American Style Sports Betting Odds Most online sportsbooks will list their odds in what is called “American Odds”. There are a couple different versions of sports betting odds, but these American Odds are the most common odds used. The most common use of odds is found when placing a bet on a sporting event. Betting agencies use historical data and team statistics to predict who is more likely to win. Whoever has the highest odds is considered the 'favorite.' If the odds are low, it means that event is not likely to occur. The magic number in sports betting is -110 because it defines the amount required by a sportsbook to earn $100 on either side of most wagers. A bettor must lay $110 to win $100 when wagering on point spreads, which are set by oddsmakers with hopes of getting equal action on both sides. Betting odds simply indicate the likelihood of an event and the return you’d get if you did make a wager on the result. Betting odds may be displayed in three different formats at US sportsbooks and online and mobile sports betting platforms: American odds, fractional odds and decimal odds.
But hopefully, once you’re done reading this, you’ll completely understand how they work. As you prepare to dive into the world of sports betting, here’s a breakdown of how the lines work, starting with …
It would be really easy to bet on a game if you could put money on a heavy favorite to win.
That’s where point spreads come in. Let’s look at an example:
Philadelphia Eagles (-4.5)
New York Giants (+4.5)
In this case, you can bet on either two outcomes: you can put money on the Eagles to win the game by 4.5 points OR MORE, which makes them the favorites. Or you can bet that the Giants will either win or lose by LESS THAN 4.5 points. They’re the underdogs.
Now, sometimes the spread “moves” during the days leading up to the game. Perhaps the Eagles’ spread ends up being -3.5 (in which they must win by 3.5 points or more to give you a victory in your bet). Your bet all depends on whichever spread you bet on, whether it was when the Eagles were favored by 4.5 or 3.5 points.
If you ever see “PK” or “pick” next to a team, it means there’s no spread and you can bet on who will win, no matter what the score is.
Let’s take that same example above but use moneylines:
Philadelphia Eagles (-200)
New York Giants (+150)
The team with a minus symbol is the favorite, and the number is how much money you would need to bet to win $100. In this case, you would have to bet $200 on the Eagles in order to win an additional $100.
The Giants are the underdogs. If they’re +150, that means you could bet $100 to win $150.
Note that you can bet any amount you want, but those numbers are always calculated and posted the same way, either in how much money you would need to wager to win $100 or how much money you could win by wagering $100.
If you’re betting on something like the team who will win the Super Bowl in the future, you might see it look like this:
New England Patriots — 3/1
Baltimore Ravens — 5/1
Kansas City Chiefs — 8/1
If you were betting on the Patriots and their 3/1 odds, you would win $3 for every $1 you spend. So if you bet $50 on the Pats and they ended up winning the Super Bowl, you’d win $150 (plus your original wager) back.
Good luck!
