If there’s one thing you know, it’s sports. You’ve been making friendly bets with your buddies for years, and almost always come up a winner. But do you really understand odds in sports betting?
Sports betting odds can be tricky to understand at first, especially since you may see the odds posted in more than one way.
From plus/minus to decimal, to fractional — how is anyone supposed to know how to place the best bets?
Don’t sweat it, we’ve got you.
A minus sign (-) means that a team is favored, whereas a plus sign (+) indicates an underdog. Want a clear understanding of risk and reward? The number underneath the spread shows you the amount a bettor would have to wager to win $100. 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.
In this guide, we’ll explain everything you need to know about how to understand odds in sports betting, and how you can start creating your own odds.
So, you want to place a bet on the upcoming match but you’re not sure how to get started.
First things first, you have to understand the odds to know which bets are worth the risk. We’ll touch more on that in the sections below.
Secondly, you need to know that there are a variety of formats for which odds are displayed, such as:
All of them are easy to understand, and we’ll show you in the upcoming sections of this article.
Lastly, odds are used to calculate the implied probability of a particular outcome in any sporting event.
Once you have a solid understanding of how the odds work, you’ll be able to determine which bets offer the best payouts and how much money you are willing to wager.
If you don’t know how to calculate sports betting odds, don’t worry, you’re not alone.
The most common type of sports odds used in North America is American Odds, which uses a plus/minus system for calculating payouts.
Below, we’ll answer your question: how are odds calculated in sports?
We’ll start with the American way, and give you some betting odds examples so you know exactly what you’re looking at the next time you want to make a wager.
But first, it’s important to know what odds are designed to do.
However, odds can be influenced by more than the events that are relevant to the outcome of the game or match.
Many traditional sportsbooks are known for manipulating the odds in their favor and factor in how much the book is charging for you to place your bet. You may hear fellow wagerers refer to this cut as the “juice”, “vig”, or “cut.”
When you see +130/-240 (or any other three-digit combination) you know you’re dealing with American odds.
The plus or minus indicates whether you’re betting on the favored team or the underdog.
A negative number on the betting line implies the favorite, and exactly how much you have to bet to walk away with a $100 payout.
Positive numbers belong to the underdog, and let you know how much you’ll win if you bet $100.
Using the above example, calculating your odds look like this:
To win $100 on the Vikings (favorites), you would need to wager $130. If you bet $100 on the Packers (underdogs), you’d be paid out $260 in addition to receiving your $100 bet back.
Let’s say you don’t want to bet $100 of your money — we get it, that can add up.
Many people prefer to place a series of smaller bets on multiple games to get the most out of the experience.
Winning two and losing one can be more appealing than losing it all in one shot.
With the above example, let’s calculate the odds of betting the underdog with only $10, instead of $100.
Using the +260 odds on the Packers, a $10 bet would payout $26 in profits, plus the return of your original $10 bet for a total of $36 back in your pocket.
In most cases, the sportsbook you’re betting with will do the calculations before you even place the bet.
You’ll know the exact payout before you confirm your bet.
If you’ve started to research exactly how sports betting works, then you’ve probably heard the term “implied probability”.
The odds are what suggest a particular outcome in any match, and the implied probability refers to the prospect of that outcome.
To calculate the implied probability you need to convert the odds into a percentage.
The reason you’d want to calculate the implied probability is to determine if the estimated probability of a match you wish to bet on is different from the sportsbook so that you can adjust your bet accordingly.
Remember, that all odds available at a sportsbook include the “juice” or “cut” so you’ll need to factor that in, as the implied probability of every conceivable outcome of a match is going to be above 100%.
This is called overround, and it’s the reason you should remove the “juice” from betting lines before calculating what the oddsmakers actually expect the outcome to be.
Of the three types of odds you’ll come across, betting with decimal odds are the easiest to learn.
Decimal style odds are typically used in Europe, but many Sportsbooks default to American odds. However, you should be able to set the preference to any betting style.
Decimal odds look like this:
|The Match||Toronto Blue Jays||2.10||Underdog|
|New York Yankees||1.40||Favorite|
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.
|Your Bet||The Odds||Winnings|
|$30x||1.40 (New York Yankees)||= $42|
|$30x||2.10 (Toronto Blue Jays)||= $63|
Calculating your implied probability is a valuable tool to determine if a wager is worth the risk.
Using our example above, we’ll determine implied probability using the following formula: 1 / Decimal odds
With the above example, the Toronto Blue Jays implied probability of winning is:
1 / 2.10 = 47.6%
And the New York Yankees implied probability of winning is:
1 / 1.40 = 71.4%
In this case, the New York Yankees have a much higher probability of winning, and therefore the safer bet… unless you know something we don’t.
Fractional odds are most commonly used in the UK and can typically be seen when placing bets on horse races.
They’re sort of funny looking odds, but when you understand what they mean, they are really easy to calculate.
Let’s say you want to bet on a horse in the Breeders’ Cup Classic.
You open up your betting app and see strange-looking figures such as 8/3 or 1/2 (which, by the way, we would say “eight to three” or “one to two”).
So, how do you calculate these odds?
The number on the left (8) tells you how many times the oddsmaker expects the related outcome to fail. And the number on the right (3) dictates how many times the outcome should succeed.
So, what does this mean for your pocketbook?
Calculating your payout for fractional betting is really quite easy.
Multiply your bet by the numerator (or top number), then divide the result by the denominator (bottom number).
For example, if you place a $50 bet on 8/3 odds the calculation would look like this:
(50 x 8) / 3 = $133.33 (a total of $183.33 coming your way).
Or if you placed your $50 bet on the 1/2 odds, then the calculation would look like this:
(50 x 1) / 2 = $25 (for a total of $75 in your pocket).
Figuring out the implied probability for fractional bets can be done fairly easily.
Let’s say your horse of choice has 8/3 odds on him, this means that out of 11 races (8+3) your horse is expected to win eight times. Pretty good right?
Now divide the number of times he’s supposed to win by the number of races on the roster and you get your implied probability: 8 / 11 = 72.7%
Remember though, it costs money to play, so anytime you’re calculating odds, whether American, decimal or fractional,the outcomes when added together will always equal more than 100%… that’s the “vig” or the “cut” we’ve been talking about.

A push — while not related to odds — can directly affect your payout so we thought it was worth mentioning here.
Being aware of the possibility of a push before you place your first bet on a sports match is important.
So, what is a push, exactly? In simple terms, it’s a tie.
You will not see a push on the moneyline when placing bets, so you need to know in advance if it’s an outcome you can bet on. Typically this only applies if you’re betting against the spread or making a totals bet.
If a push occurs and hasn’t been bet on, then you’ll just get your money back, as it’s considered neither a win nor a loss.
A point spread will usually add half a point to each number so that a push can’t happen, but that’s not always the case, so keep your eye on your bets and all possibilities of a push.
