And, if you ever have any questions, please drop us a line at webmaster@explainbettingodds.com where we can answer all of your questions through email.

The short answer to the question of 'what do the plus and minus signs before the odds number mean' is: a minus sign indicates a favourite to win, while a plus sign indicates an underdog. For instance - let's say that a team is -145 to win a game. Plus, it will help you to avoid making silly mistakes like placing big bets on events that actually have bad odds. Who sets the odds for sports betting? Most bookmakers use their own teams to calculate odds based on various criteria, from the location of the match and the weather, to player absences or injury risks.

The decimal odds show the number that you can use to calculate the total amount of money you win: for example, 4.98. Since our focus lies on the meaning of the plus sign and the minus sign, we focus on the American odds. These are also called the moneyline odds, as lots of sports bettors use this odds type for their moneyline bets. You’d win your $100 back plus make $49 profit. If you bet on the underdog Rua in the fight for $100 at odds of 2.65 you’d win back $265, which includes your $100 stake plus $165 in profit. To find out how much you can win using decimal odds you multiply the odds by how much you want to bet. Fractional Betting Odds Explained.

Different Types Of Betting Odds Explained

Quick Explanation Of How To Read Sports Betting Odds

• Point Spread - If A Football Team Is -7, Then That Team Must Win By 8 Points To Win The Bet.
• Over / Under ' AKA The Total' - If An Over / Under Is 42 In A Football Game, The Combined Total Amount Of Points Both Teams Must Score Needs To Be Over 43 Points To Win The Wager.
• Moneyline Betting Odds - If The Money Line Has “Team A” at -150 Betting Odds Against The Colts, I Must Bet $150 To Win $100 And If Team A Wins, Then I Would Win My Bet.There are three forms of regular betting odds that you will see at every sportsbook that you visit, whether online or in person. These are the ones that you see right off the bat and the ones that really matter when you are betting on sports. If nothing else, you have probably heard them talked about by either your friends or TV broadcast on ESPN or other channels.

How To Read And Understand MoneyLine Betting Odds

First there are the moneyline betting odds , which is the bet on who will win the event outright with no point spreads or other variables. You simply pick the team you think will win and place the bet. However, without using the odds, the payouts are usually much different then they would be with the odds in place.

When betting on the moneyline, the favorite will always have a negative symbol in front of the number and the underdog will always have a plus sign in front of it (an example is -150 favorite or +150 for the underdog).

How To Read The Point Spreads

Next, we come to what may be the most common type of sports betting odds, which is the point spread. They put point spreads up for all of the main sports such as football, basketball, hockey, baseball, and others. This is called 'The Spread' and it basically tells you which team is favored and by how much. When betting the spread, you are betting that a team will win by a certain number of points, runs, or whatever. Here is an example to help you understand point spreads in football.

If you are Betting The Point Spread On 'Team A' in Football - Favored by -6 - This means 'Team A' must beat the other team by 7 points or more to win the bet.

If You Are Betting The Point Spread On 'Team B' in Football Game - Underdog that is getting +6 points - This means as long as 'Team B' does not lose by 7 or more points, then you will win the bet. If Team A wins, but only by 3 points, then you will still win and get paid.

How To Read The Over / Under Betting Odds

There is also the total score or the over/under, and this line lets you bet on whether or not the total score between all competitors will go above or below a predetermined amount. You simply look at what the Over / Under is and then bet on which you think it will be. There are over and under betting odds for pretty much every sport including baseball, football, hockey, UFC, Basketball, Horse racing, and much more.

The over/under betting odds, or the totals, work differently for each sport. If the number is 42 in a football game and you bet the over, you would need 43 points total between the two teams. In baseball betting, it is the number of runs scored that sets the total. The UFC over/under betting odds are which round the fight will end. Hockey totals are how many goals will be scored between both teams.

With the spread and the total, you will occasionally see that the odds are distributed with 'half points,' which are in place to prevent a 'push,' or no one winning or losing the bets. As long as there is a winner or loser, the sportsbooks will make their money on the juice and be happy.

What To Know About Vegas Betting Odds

The truth of the matter is that Vegas pretty much sets all of the sports betting odds for the entire world. All of the world’s leading experts work for the big casino companies in Las Vegas, and all of them work together to set the odds for different sports. Anytime you hear someone asking or talking about Vegas odds, they are simply talking about the odds and nothing specifically related to Vegas. All of the online sportsbooks use services that simply use the Vegas odds as a starting point for events. Then their own systems will adjust the spread depending on how people are betting at their sportsbook. Ultimately a sportsbook wants 50% of the bets on each side of a game so that they can simply make money on the juice.

Exotic Betting Odds Explained

Exotic bets are there to make for a more entertaining betting experience, but they work somewhat differently compared to the straight bets. But, the original point spread is still used in all these bets no matter how you look at it.

Parlays are essentially a combination of two or more bets into one, such as three teams winning their respective matches. These parlays are usually a long shot since so many teams have to win, but in the end, they are also some of the highest paying games. You can pick teams to cover the point spread, over or unders, or moneylines in a parlay and sometimes you can mix in different sports.

Pleasers are some of the highest paying bets, as they take the spread and then subtract points, making it harder to succeed. Then you also have to combine them into another bet of the same type in order to win. The payouts are huge, but it is not likely that these will come in unless you have the utmost luck or some sort of inside knowledge.

Teaser bets bets are the exact opposite, in that you can adjust the spread to be more favorable, thus lowering your payout but increasing your chances of winning. Either way, these are some of the more exciting ways for you to wager.

There are also 'If-Bets', which allow you to combine two bets. The first bet has to win for the second bet to have action. If the first bet fails, the second bet doesn't come through. If you win the first bet, you can then use the winnings on the second bet, essentially building your bankroll.

Different Formats Of Betting Odds

How To Read American Betting Odds

American odds have become incredibly commonplace, despite the fact that they are not as easy to read as other formats. As an example, American Odds read like this:

Odds To Win Super Bowl:

• Team A: -150
• Team B: +200
• Team C: +600
• Team D: +1000

With American odds, the number represented is how much you have to bet to win $100. If the number is preceded with a '+' sign, then you would risk less than $100 to win a wager worth $100. And, the opposite is true when the number is preceded with a '-' where the bettor would have to risk more than $100 just to win $100 of the wager.

In the example above, you can see that Team A has the lowest number of the group and are considered to be the favorite to win this bet. If you wagered on Team A to win the Super Bowl and they end up winning, you are going to need to risk more than $100 to win $100 as indicated by the '-' symbol preceding the payouts. In this particular example, a bettor would need to wager $150 to win $100.

On the opposite side of that, the other 3 teams in contention all pay better than 1 to 1 odds (risk less than $100 to win $100). Team B is at +200: risk $50 to win $100. Team C is at +600: risk $16.67 to win $100. Team D is at +1000: risk $10 to win $100.

These can be a little bit confusing but if you just pay attention to the + or - symbol then you should not have any issues. And, with a little bit of manipulation, you can see how these odds will pay if the wager ends up being a winner and that is what we're all here for... to win.

How To Read Fractional Odds

Fractional betting odds are the easiest to understand. Just about every single sportsbook that caters to Americans has the option available for fractional odds. And, while they may seem daunting at first, you don't really need to understand complex fractions in order to utilize these odds. Let's look at an example:

Odds To Win Fight:

• Fighter A: 4/7
• Fighter B: 3/2

In order to best understand these lines, you first need to look at the ratio to 1. In the example above, 4/7 odds is less than 1 and the opposite can be said for the other side as 3/2 is more than 1. Once you have determined this, you can figure out the favorite.

To figure out which side is favored, you simply need to figure out which is the lower number. In this case, Fighter A is at 4/7 odds which is less than 1 and Fighter B is at 3/2 odds which is more than 1. Fighter A's wager is the clear favorite as it is the lower number.

So, how do you figure out what these pay? Again, we refer back to 4/7 being less than 1, and 3/2 being more than 1.

Anytime fractional odds are displayed at a value of less than 1, the bettor must risk more than they intend to win if the wager is a winner. And, the opposite can be said for if a fractional value is more than 1... that bet will pay more than what is risked.

As we said before, 4/7 odds are less than 1 so in this case, the bettor must risk $7 to win $4 from the wager. Then, 3/2 are more than 1 so when risking $2, the bettor will win $3 off the wager. As you can see, the payouts are in the fractional odds, you just need to know which way they go based on if they represent a value greater than or less than one.

Understanding Betting Odds That Use Decimals

Decimal odds are slightly more confusing than most other types of odds. In fact, we prefer not to use them when we bet but that is just our preference. Regardless, we are going to give you a little insight into these lines, as we want to give you insight about all of the common types of odds available.

If you look into these odds, you will definitely come out a little bit confused unless you are from Europe where these odds are commonly used than American or Fractional odds. The multiplication game is not as straight forward with decimal odds. Let's take a look at another example:

Odds To Be Next President:

• Candidate A: 1.50
• Candidate B: 2.45

When looking at decimal based odds, the same thing applies to them as all the other forms of odds when trying to determine the favorite... whichever is the lowest number is favored. In the example above, the favored candidate is Candidate A at 1.50 however Candidate B is only a little bit behind at 2.45

Figuring out the payouts is where decimal odds can get tricky, but you'll soon learn a little trick that will make these very easy to understand.

The best way to start off look at these odds is to consider them to be monetary amounts based on what you will win if you wager $1 or one euro, one pound, etc... which includes the original wager. Be sure to keep that in mind when looking at the other odds types.

If Candidate A wins the election, every $1 wagered will win $.50 plus the original $1 wagered which equals $1.50 or 1.50 odds.

Candidate B: every $1 wagered earns $1.45 which equals $2.45 or 2.45 odds.

Now That You Know How To Read Sports Betting Odds

Now that you understand how to read odds, you will then want to see how they are adapted to the different betting lines. With the straight wagers and exotic wagers alike, you will find that these odds are worked into the lines. After you figure out how to read the odds, you will then have to figure out the different types of bets that you can find through most sports betting sites. The different types of bets use odds somewhat differently, but in the end, it is all fairly similar.

We have created special pages that explain how to read the betting odds on a variety of sports. The reason for this is that some sports have betting odds available that others do not. Some sports betting odds can be broken down into a half or quarters while others are just for the entire duration of a match or game. For instance, you cannot really compare the NASCAR or PGA odds with NFL, and vice versa. Each page is crafted specifically for an individual sport making it easier for bettors to learn the ins and outs of betting on whichever sport they choose.

The big board at any Vegas sports book is a sight to behold. A slick cross between the New York Stock Exchange and a McDonald’s walk-up menu, the boards are updated moment to moment and bet to bet, giving a sports gambler all the data he needs to make a smart bet.

These boards are copied and pasted into the newspapers or shrunk to fit computer screens and smartphone apps but nothing measures up to the real thing. Hundreds of games, thousands of bets. All listed above you.

The big boards in Vegas tell us many things. The favorites. The underdogs. The payout. Where the money is. Knowing how to read Vegas Odds is important to every gambler not just to place a bet, obviously, but to place a smart bet. And that’s all good gamblers want to do. They want to make smart bets, win 60-70 percent of the time, and move on to the next bet.

But how do the big boards in Vegas work? What are they telling us? And what can we derive from them? It is just as important to know the odds you’re gambling with as it is to know the sport you’re gambling on. Making a smart bet is the goal. And smart gamblers use all the information available in order to do so.

For a brilliant summary for reading Vegas Odds 101, listen to our Sports and Vegas Odds Podcast episode where Ryan breaks it all down for you:

American Odds

Vegas odds are often referred to as “American Odds” because Americans always have to be different. We ignore the metric system. We call football, soccer. We drive on the wrong side of the road. Why would sports gambling be any different?

American odds are presented in the form of a $100 bet. They’ll indicate the amount you need to wager to win $100 or the amount you’ll win if you bet $100. So, for a favorite, the odds will begin with a minus (-) sign. This is the amount you need to bet in order to win $100.

On the other hand, the underdog’s odds will begin with a plus (+) sign. This is the amount you will receive if you were to bet $100. This does not mean you have to bet $100. Or mean that you can only bet as much as $100. See, Americans have to be different. Hang in there because we have some examples forthcoming.

These odds will come into play a few ways depending on the type of bet you place. The moneyline, the point spread, and the totals (over/under) are all bets available on the board. Let’s look at how to read them in Vegas with the odds.

The Moneyline

Simply put, a bet on the moneyline is an odds bet. It’s where “American odds” can easily be seen. With a moneyline bet you’re simply picking the winner and the payout is determined by the odds.

Obviously, a bet on the favorite is going to pay out less than a bet on the underdog. Let’s look at an example of a moneyline bet with an NBA game and how it would appear in Vegas. The Pacers/Cavs line.

• Indiana Pacers +350
• Cleveland Cavaliers -440

The Pacers are the underdog on the moneyline at +350. The Cavs are the favorites on the moneyline with -440. This means a $100 bet on the Pacers to win pays $350. And that you would have to wager $440 on the Cavs to win $100. This ratio holds true for a wager of any amount. A $10 bet on the Pacers pays $35 while a $10 bet on the Cavs pays $2.27. So on and so forth.

The Point Spread

The most common and popular of sports bets is the point spread. As simply as we can put it, the point spread is the number the oddsmakers use to handicap the favorites to even-up the final score of the game. This in turn sparks more interest, which leads to more bets, which brings in more money. Again, the Pacers/Cavs line.

• Indiana Pacers +8 -110
• Cleveland Cavaliers -8 -110

First the -8. As noted, the Cavs are the favorites so they are giving points (8) to even up the final score. In order for the Cavs to win the bet and cover the point spread, they’d have to win by nine or more. If the Pacers stay within seven points, the Cavs fail to cover the eight points and lose the bet. If the Cavs win by eight points, it’s a “push” or a tie and all bets are returned.

Now the (-110). This number is the odds a bet on the point spread will pay out. Just like on the moneyline, since the Cavs are the favorites, you’ll have to bet $110 to win $100. You’ll notice a favorite covering the spread pays out much better than a favorite on the moneyline. You’ll also notice the favorite and the underdog have the same payouts with the point spread. This is what makes playing the point spread so popular.

Some teams are evenly matched and there isn’t a point spread at all. This would be a “pick’em” or “pk” on the big board. And the odds on the moneyline would match as well. These are “EVEN” odds. When playing the point spread the payout number will vary. -110 is about industry standard but you’ll notice -105’s, -115’s, and even as high as -125’s on point spread bets at times. More on this later but it is important to note these variations.

Totals

The totals is a bet on the total number of points (or runs or goals) scored in the game. The oddsmakers will set the number and bets are placed on whether or not the total score is OVER or UNDER that number. The number appears on the big board next to the underdog like so:

• Indiana Pacers vs. Cleveland Cavaliers 212.5 -110

Plus Minus Odds Calculator

The number set for this game is 212.5. Since the .5 has eliminated the chance of a push, an OVER bet will win if the total score is 213 or higher. An UNDER bet pays if the total score is 212 or lower. And, again, the payout for a win is -110.

Totals bets are seen as something of a sucker’s bet. Despite your opinion on the matter, we have to admit they are a little strange. You are wagering on what the total score will be. Not picking a winner. Picking a score.

So, it’s different than a normal who’s-going-to-win-the-game-and-by
-how-much kind of bet. However, this number is providing the gambler more information about how the oddsmakers feel about the game and that is important when making a smart bet.

Placing a Wager

The other set of numbers you will see on the big board are the rotation numbers. These are numbers assigned to teams so the sports book can easily distinguish one for the other. They appear to the left of the teams in a game on the big board as such:

• 101 Indiana Pacers +350 212.5
• 102 Cleveland Cavaliers -440 -8(-110)

These numbers simply help the sports book as well as the gambler keep track of the bet. Listed on the big board are dozens of sports, hundreds of teams and thousands of bets that can be played. It’s a good idea to keep them as organized as possible. There are at least six professional teams in New York by itself after all. Like the horses’ numbers at the track, rotation numbers just cut down on the confusion when placing a bet.

“Give me New York -220 on the moneyline for $50.”
“Which New York, dumb-dumb…”
“Sorry, 303. I’m an idiot”
“Yes, you are.”

Don’t be that guy. This is the proper way to lay a bet in Vegas. Rotation Number, Type of Bet, Amount of Wager. Everyone appreciates a well placed bet and no one likes that guy…

Reading the Big Board

Now that we know how to read Vegas Odds, we need to learn what the Vegas odds mean… That is, what are these numbers telling us in the context of the game we want to wager on. We have studied the teams, we know the rosters. What can the lines tell us to make our bet a smart bet?

Once a game is scheduled and it’s odds are posted, the bets are going to start coming in. Now, it’s in the sports book’s best interest to keep the bets as even as possible. This is why oddsmakers give you a pay out at -110.

Understanding the Vig or Juice

That’s a $110 dollar bet to win $100. Take the favorite and give the points. You’re paid out at -110. Take the underdog and get the points. You’re paid out at -110. OVER or UNDER the same. -110. This is the industry standard and goes back to the mob-only days of oddsmaking.

Where does that $10 bucks go you ask? Well, that $10 bucks on a $100 bet is the “vig” or “juice.” It’s the price for laying a bet. A little bit extra the oddsmaker gets to keep for fronting the wager.

Keeping the bets as even as they can on either side insures their money. Collect from the losers and short change the winners. It’s a brilliant business model only the mob could come up with and only Vegas would still employ.

Now, most betting lines will just give it to you straight. The favorite pays this much, you get this many points, the total is this. What we are looking for are the variations. We can ascertain plenty of valuable intel from these variations.

Vegas Odds Plus Minus

Why is the payout on this game -115? And why is the payout on this game EVEN? Why is the moneyline different from yesterday? And why is the point spread moving up? The devil is in the details.

Watch As The Point Spreads Move

The most obvious variation is the movement of the point spread. As the bets start coming in, the oddsmakers track which team is receiving most of the betting action. The point spread will move because the oddsmakers will change the line to try to even up the sides. Remember, they want just as many people on one side of a bet as on the other.

More people are taking the Cavs giving the eight points? Raise the point spread to nine. All of a sudden, more bets will come in for the Pacers getting the nine points. Oddsmakers can do the same with the moneyline as well as the total line. And for the same reasons.

But what does this information tell us? The line has moved up even more and now the Cavs are -10 point favorites. This means, despite the oddsmakers best efforts, more wagers have been placed on the Cavs than on the Pacers.

Smart Bettors Know Where The Action Is

Knowing where the money is can help you make a smart bet. One theory is the The-House-Always-Wins-Rule. Basically, this theory suggests you bet against everyone else and with the house because the house always wins. If more people take the favorite, the points they are giving went up and you should take the underdog.

If more people are picking the underdog, the points they are receiving have gone down and you take the favorite. It makes sense in theory but maybe not in practice. Remember, the oddsmakers want the sides to be even.

They aren’t in the business of placing their own opposing bets. What is important is knowing how everyone else is betting and the knowledge that a large segment of the gambling population shares your opinion.

Or if you think the gambling population is foolish, well, you know what to do. However you feel, keep an eye on how the line moves. It may help you make a bet you wouldn’t have or avoid a bet you were going to make.

A Close Look at the Payouts

Explain Plus Minus Odds

The payouts on the point spread can vary as well. That standard -110 will turn into -105’s or EVEN’s. Or go the other way to -115’s, -120’s, or -125’s. What is the reason for these variations? It’s a lot like moving the point spread.

The oddsmakers want to even up the bet. There’s only so many points a bookie is going to give. Offering a little more here or a little less there on the payout may be enough to influence the betting action. However, you can tell where the oddsmakers are hedging with these numbers.

If the payout gets better than -110, the oddsmakers have the sides even up, love the point spread and want you to bet it and lose. If the payout gets worse than -110, the oddsmakers know they have a bad number and want to cut their losses.
