Betting odds, especially for novice bettors and for those that are new to sports betting, can be difficult to grasp. There are several types of betting odds that are offered to players, but they all have one common theme – they reflect the probability of an outcome in a sporting event.

In every sporting event, there can be a wide degree of difference from one outcome occurring compared to another. Betting odds are the interpretations of these chances in numerical form. Of course, since the bookmakers charge vigorish, the odds won’t reflect the true probability of an outcome but more on that later.

Depending on what part of the world you’re betting from, you’re likely to become accustomed to one form of betting odds or another. Online sportsbooks these days will offer their customers odds in several formats, but it’s important to understand each odds format.

Also known as moneyline odds, American odds are used primarily by those based in the United States. American odds are simple to understand. The odds are based off the amount that must be bet for the bettor to win $100.

What does 'plus' and 'minus' mean as a sports betting term? Odds expressed in terms of money, with $100 being the standard. If the odds are minus (–), then that amount of money must be wagered to. Knowing how betting odds work will also come in handy when you want to bet on multiple matches or even on multiple features from a single event. Many bookmakers offer multiple bets on single events so things can start to get a little more complicated when you move away from simply making 1 bet. It's important to know how odds work and how to read sports betting lines, as online sportsbooks will display odds differently, based on the sport and location you're betting on. Our betting odds calculator is free to use and presents the different types of odds. How Do You Understand Odds in Sports Betting With Decimal Odds? Calculating your potential winnings with decimal odds is easy. All you have to do is multiply the amount of money you’re wagering with the odds attached to the team you’re betting on. Decimal Style Sports Betting Odds Decimal style odds are used mostly in Europe, and are pretty easy to understand. To calculate the decimal style odds all you will need to do is simply multiply the amount you wish to wager by the decimal odds shown and you will get your payout. For example it may look something like this.

Sports like baseball are bet solely with moneyline odds because there is no point spread. However, traditional point-spread wagering will also have American odds attached. The standard bookmaker’s vigorish is -110, which will be the standard juice attached to sides and totals.

Here’s a basic example using an MLB baseball game:

In terms of moneyline wagers, like all baseball contests, the favorite will be signified with a – negative symbol and the underdog with a + positive symbol. In the above example, the Reds are the favorite, and the Cubs are the underdog.

Bettors would need to wager a stake of $130 to win $100 if wagering on the Reds. For the Cubs, a $100 bet would return $120.

Here’s an example of American odds attached to an NFL point spread.

The moneyline odds attached to each side of the point spread are -110. To bet either side, NFL bettors will need to bet $110 to win $100. For Americans, this 10 percent vigorish is standard. However, bookmakers often change the attached vig on point-spread markets. This is another way for them to move the line without coming off certain numbers.

Decimal odds are the most commonly used odds type by online bookmakers. They are the favorites of most Europeans, excluding the United Kingdom, and by Australians. Decimal odds follow a simple and basic formula.

Here is an example of a wager placed on the favorite in an English Premier League soccer match:

Fractional odds are predominantly used throughout the UK and Ireland. They are also known in the UK as UK Odds. First appearing in horse racing, they are the oldest form of odds in sports betting.

We all learned fractions as kids in school, and using fractional odds is no different. When using fractional odds, the second number to the right is the denominator, and it signifies the amount of the stake. The first number and number to the left is the amount that your stake will yield (not including the original stake) if the wager is a winner.

Here’s yet another example using English soccer:

Here is another example, this time with an odds-against underdog:

Many bettors will want to convert fractional odds to moneyline odds or decimal odds to American odds, etc. This can be done using some basic math, but in today’s bookmaking age, it’s not necessary.

Most sportsbooks offer several different odds types, so changing betting markets into different odds types can almost always be done with a click of a button. Bettors can also Google the term “odds converter,” and they will be met with several betting calculators that provide this service as well.

Do Betting Odds Represent the True Probability of an Outcome?

While betting odds are indeed the best barometer for predicting the outcome of a sporting event, the odds don’t necessarily reflect the true likelihood or probability of the outcomes concerned.

How Do Betting Odds Pay

For instance, if we flip a coin, we know that there’s a 50% chance that it will land on heads and 50% chance it will land on tails. When a bet is placed, we will either win our side of the wager or lose (or push in some cases). This seems like a 50/50 proposition as well, but the bookmaker’s vigorish adds an edge to both sides of the bet.

Furthermore, the odds can be influenced by other factors. Not every bookmaker has the same opinion on a game, and the odds may also be affected by how much exposure a sportsbook has to each market. If they are taking a lot of action on one side, the odds will likely move due to the increase in wagering volume.

As a sports bettor, our goal should be to look for markets with the smallest edges held by the sportsbook. The closer we can get to the 50/50 coin flip odds, the less the sportsbooks will make off us in the long run. Of course, betting with no juice isn’t possible, but line shopping and cutting down on your edge is something that all bettors can do easily.

Kansas City Chiefs (-250), Las Vegas Golden Knights (-110), Toronto Raptors (+125) – the chances are that you’ve come across these sorts of options in your sports betting journey. If you don’t know what these numbers mean, you’re not the only one.

A large number of betting newbies have no idea what the figures are representing. If you want to learn, you’re at the right place. We’re now going to show you how Vegas odds work. We will also explain the process of making the odds. We’re even going to show you how to use this knowledge to your advantage.

What Are Vegas Odds?

Vegas odds a.k.a. American-style odds are the ones you will see in the land-based sportsbooks across Nevada. Caesars, Wynn, Golden Nugget – all these bookies are using the Vegas odds format.

The trouble is that they may seem strange to the inexperienced eye. However, everything becomes clear once you learn more about them. So, how do Vegas odds work?

These odds come in the form of three-digit numbers, which can either be positive or negative. If the number is negative, it means that the team is the favorite. If it’s a positive number, it’s the opposite. If the number on each potential outcome is -110 (or sometimes -105), it means that each team has an equal chance of winning.

The big question is how can you use these odds to figure out how much money you’re going to cash in if your bet wins? That’s the question we’re going to answer next.

How You Calculate Vegas Odds?

You calculate your potential win based on whether the odds come as a positive or a negative number. If the odds are positive, e.g., +150, it practically means that this is how much you can profit if you bet $100.

Let’s say you want to bet Justin Gaethje at Vegas odds of +150. If you put, $100, you’re going to make a net profit of $150 if he wins. But, what if you’d like to bet a different amount?

In that case, you need to use the following formula:

Vegas Odds/100 x Your Stake

So, let’s say you wish to put $70 on Gaethje, your potential net profit is calculated by dividing his odds by 100, then multiplying the number with 70.

Use your calculator and you will see that 150/100 x 70 equals 105. That is how much you will make if Gaethje wins. Note that $105 is your net profit, while you’ll also get your $70 stake back. So, your total win would be $175 on a $70 bet.

An important thing to remember is that the aforementioned formula only works if odds are displayed as positive numbers. If the number is negative (e.g., -150), you need to go with a different formula. In that case, this is what you got to use:

Your Stake/Vegas Odds x 100

This is because, with Vegas odds, the negative number represents the amount of money you need to bet in order to win $100. So, if the odds are -150, you will have to bet $150 to get a net profit of $100.

Is There a Simpler Alternative?

Vegas odds are traditionally used in land-based sportsbooks across Nevada. It’s been like that for decades, and when online sports betting became legal in other US states, most operators decided to embrace this format.

The same was the case with offshore sportsbooks that cater to American customers, with one important difference – BetOnline.ag, MyBookie.ag, SportsBetting.ag, and many other bookies let the players decide on the odds format.

So, if you find Vegas odds too complicated, you can always use decimal odds in offshore sportsbooks. How they work is that your stake is multiplied by the odds. The result you get is your gross profit (your net profit + your stake). For example, if the odds on Tampa Bay Buccaneers are 1.65 and you wish to bet $90, your potential win is $148.5.

Who Sets the Odds in Vegas?

When speaking about Vegas odds, there’s another question that pops out – who decides them? Some sportsbooks employ teams of oddsmakers to come up with the odds, while some hire independent companies to do the work for them.

In both cases, the goal is to set the odds in such a way that they attract equal action on both outcomes. This way, the sportsbook is going to make profits regardless of the outcome. As a result, the Vegas odds on the favorite are always negative numbers, while underdogs get positive numbers.

Oddsmakers take into account various factors to decide who’s the favorite/underdog. What we’re talking about are power rankings, game locations, the form of the teams, and so on. However, this doesn’t necessarily mean that Vegas odds equal the true probability.

Understanding Sports Betting Lines

Using the Odds Knowledge to Your Benefit

The thing about odds is that they change all the time. For example, there might be some big news coming from a team’s roster, such as an injury of a key player. You can be sure that the sportsbooks will adjust the odds in that case in order to protect themselves.

Still, the #1 reason why odds change lies in the behavior of the bettors. If the players suddenly start betting on one outcome, the sportsbook will have to react by adjusting the odds. They will move the odds on the outcome in question (e.g., from -128 to -175), while moving the odds against the opposite outcome (e.g., from +108 to +155).

This way, they are making sure they aren’t going to have to pay out too much money if the favorite wins. At the same time, they are encouraging bettors to put their money on the underdog with the odds more lucrative than earlier.

How To Read Betting Odds

How can you use this knowledge to your benefit? You can go on an odds hunt. If you compare all the odds available, you will be able to find the best value for your bets. It may be at a Vegas-based sportsbook or it could be at an offshore website, you’ll find out only after you’ve compared them!
