Sports Bets Odds Explained

Welcome to the Sports Betting Odds section of The Sports Geek. If you are new to sports betting and don’t understand how to read betting odds (+150, -110, +2200, etc) we will lay it all out for you and help you learn how the betting odds work.

Sports betting odds are a way for customers to predict the result of a sporting event and wager an amount of money on that outcome. The bookmakers provide the odds for customers and are betting.

Sports Betting Odds Explained

Many people don’t know how to read or calculate sports betting odds, so below we have done our best on explaining how betting odds work. The most common type of sports betting odds used in North America are the American style odds which we explain below.

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. Reading and understanding sports betting odds can bet a little confusing to beginners, so we have provided an example below using two NFL football teams:

American Odds

• Matchup Odds
• New England Patriots +120
• Pittsburgh Steelers -140

Explain Sports Betting Odds

The number shown in the bracket represents the odds. The American Odds have two components to them, the first being the positive or negative sign, and the second being the number that follows the sign.

The sign in front of the number indicates whether placing a wager on that outcome will pay out more money then you have wagered or less money then you have wagered. If the odd is negative (-) it means that outcome is more likely to happen and placing a bet on that outcome would payout less than the amount you wagered, while a positive (+) odd shows that the outcome is less likely to happen and it would pay out more than the amount you wagered.

The next step is figuring out exactly how much the bet pays out, which is where the numbers in the odds come into play.

A listed odd with a – sign in front of it, such as the -140 in our example above, shows us how much money you would need to wager in order to win $100. So using the -140, this would show us that you would need to bet $140 in order to win $100 in profits. You can easily substitute the $100 bet for a $10 bet by moving the decimal place over one spot, showing us that you would need to wager $14 in order to win $10 in profits.

Examples:

A listed odd with a + sign in front of it, such as the +120 in our example above, shows us how much money you would win on a $100 bet. Using the +120 odds, it shows us that a $100 bet on that outcome would pay out $120 in profits. Again this can easily be converted into smaller or larger size bets. A $10 bet on +120 odds would pay out $12 in profits.

Examples:

Below is an example of NFL betting odds taken from an online betting site.

In this example you can see Los Angeles is listed at +130 ($100 bet pays $130 plus of course your original wager back) and New England is listed at -150 ($150 bet pays $100).

The great thing about betting online is that the online sportsbooks will do the calculations for you before you place your bet. You can click on the outcome or team you would like to bet on, and then input the amount you wish to wager and it will show you your potential pay out before you confirm your bet.

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:

If you wanted to place a $10 wager on the USA at 2.40 you would simply need to multiply your $10 wager by the 2.40 odds (10 x 2.40) to find out that the payout is $24. It is important to realize that with decimal style odds it includes the amount you wagered, so to find out profits you would need to subtract your wager ($24 – $10) to find out your potential payout is $14 in profits.

If you wanted to place a $10 wager on Brazil you would again just multiply $10 x 1.55 to find out that you would win $15.50 total or $5.50 in profits.

Decimal style betting odds are very simple to understand, but you won’t see them displayed in many North American sportsbooks. With that said, most online betting sites will allow you to chose the style of betting odds you want displayed, with American odds set as the default.

Getting action on a game can add a thrill factor that is hard to find in any other aspect of life. Making some money while doing it, well, it doesn’t get much better than that. But what happens when you jump onto your favorite sportsbook and they bombard you with a series of numbers (odds) which are meant to represent the chances of your team winning, when all it really looks like is math on steroids!

If this is how you feel when your trying to place a wager, read on. The following is a simple guide on how to read sports odds and give yourself the best chance of taking home some cash.

What does +200 mean? +200 is a specific set of odds attached to a given sports event. These are in the form of ‘American’ odds’. The +200 represents the amount a bettor would win if they had wagered $100. A profit of $200 and a total payout of $300. Other types of odds are Decimal and Fractional.

What Types of Odds Do Sportsbooks Use?

Globally sportsbooks use one of three types of odds:

Understanding Sports Betting Odds

1. American
2. Fractional
3. Decimal

There are positives and negatives in the use of all of them. One thing is for sure, if you are going to bet on sport, you will run into one of these odds formats and you NEED to know how to read, understand and eventually capitalise on them.

This article will focus heavily on American odds.

How to Read American Odds

The basis of American odds is that they reflect two different aspects to the bet:

• in the case of the underdog: how much money a gambler will win if they bet $100,
• in the case of the favorite: how much a gambler needs to bet to win $100.

Quite a big difference between the two, and definitely a little tricky to navigate at first.

The following is an example of the moneyline market using American Odds, which was offered by a sportsbook during the NBA playoffs

Note:As the Portland Trail Blazers are the home team they are listed second in this market. Interestingly in many international or offshore sports the home team is listed first. Perhaps in this case the home court advantage is what has led the sports books to install the Trail Blazers as the favoured team.

We can tell Portland has favoritism as the odds have a minus sign at the front. Any time a team has minus sign out front, the bettor knows they will be receiving less than a 2 – 1 payout figure. In fact in this case, to win $100 wagering on the Trail Blazers you would need to stake $128.

In this particular example, the Oklahoma City Thunder are the outsider or underdog as they have odds with a plus sign at the front (plus money). This means if you bet $100 on OKC then you would collect $105 profit, a total return of $205.

Clearly the bookmakers considered the game to be potentially close and therefore odds were reasonably tight. As it turned out the Trailblazers dominated the second half and ran out convincing winners 114 – 92. Moneyline bettors who took Portland, go to bed with a tidy profit. In actual fact the margin of victory is irrelevant as the Moneyline requires just one condition be met, a win.

How to Do the American Odds Math?

Despite the American odds looking confusing at first sight, the underlying math is not too difficult. Having said that it could be much more user friendly.

Another key point to remember is that American odds do not include the original stake in the calculation. They only reflect the profit from the wager. The original stake needs to be added to reflect the total payout or total return figure.

Referring back to the previous example the following math applies:

The issue with this way of reporting odds is that the bettor has to do more than one level of calculation themselves. While it’s all fairly straightforward it does affect the user experience negatively.

Sports Betting Odds Explained

How are American Odds Different to Decimal Odds?

The decimal odds system, which is being increasingly used by sports bookmakers across the globe, removes the extra step of calculation required by the bettor when American Odds are in use. It is a much simpler method to offer odds on the identical market and immediately gives a total return or payout figure by using one simple multiplication.

The NBA example used earlier in the article using decimal odds would read as follows:

The payout calculation is where the ease of decimal odds is highlighted:

Underdog:

Favorite:

It is clear that the decimal method is a much simpler way for sport bettors to calculate their potential winnings than than the American odds system.

Another downside to using American odds is that they are almost unusable when working with parlay betting. A parlay or multiplier is where a bettor takes classic bet types and parlays several of these into one wager. In order to multiply the individual odds to create the parlay payout figure, the moneyline is first converted to decimal odds. Highlighting the extra step of math sportsbooks require bettors to do when they solely offer odds in the American format.

It is hoped that one day soon most sports books will offer decimal odds instead of American odds. As legalized sports betting explodes in popularity across the US and more mobile sports betting platforms come online, it is hoped that at the very least, functionality to switch between types of odds is added to all betting apps. After all, sports betting is about entertainment, and user experience should be the number one focus from all corporate bookmakers.

How to Identify Sportsbook’s Margin When Using American Odds

Sportsbooks clearly need to make money to continue to operate and therefore it is understandable that they will take a cut along the way. Understanding when that cut is too large is critical in giving yourself the best chance of turning a profit.

When dealing with American odds on 50/50 markets like total points or point spread the margin is quite simple to recognise.

For example the market on an NBA game may be offering an over/under points total of +/-214.5 points.

In this market, without any bookmaker edge, the odds would read +100 for each option. That is a doubling of the bettors money based on the market essentially being a coin flip. $100 invested would return a profit of $100. Clearly this is not the case in reality. If you spot a market like this through a sportsbook promotion (a rare occasion), then load up!

The sportsbook is only offering -110 meaning a bettor would need to invest $110 to return a profit of $100. This equates to approximately a 4.5% margin (vig) for the book. To be profitable long term the bettor would have to correctly pick this market 53% of the time. A tall order.

Some books will offer a smaller vig, for example -108 but others will be less generous and wind their margin out to numbers like -112. These numbers are often seen in live betting markets due to the greater perceived risk the sportsbook take on with live markets.

It is best, as a rule, to avoid markets where the market is skewed too far in the favor of the book.
