Did you know that, according to one UK-based bookmaker, there are 500/1 odds of Kanye West becoming the next US president? Depending on your viewpoint, it’s a brave or foolish bet. But while political betting markets aren’t offered in the US, these odds wouldn’t read as 500/1 in American bookies. They’d instead read as +50000, while it would be presented as 501.00 in Australia. That is to say, there is no single odds format used universally across the world. In this article, you will get to know the difference between American odds, fractional odds, and decimal odds.
As the name suggests, American Odds are popular in North America, with decimal odds of 3.00 being converted to +200. However, to make things more complicated, decimal odds of 2.00 are expressed as. The calculation for decimal to American odds also depends on whether you’re converting odds on an underdog or favourite. For decimal odds of 2.00 or greater, you simply minus 1 and multiply by 100. So for decimal odds of 3.00, you do this: 3 – 1 = 2. American odds use the plus and minus sign to convey the potential return for any bet. American odds always use a baseline value of $100. A negative number indicates how much you’ll have to bet to win $100, and a positive number indicates how much you’ll win if you bet $100. Therefore, a negative number indicates an ‘odds-on’ favourite. This would be 3.00 in decimal odds, and 2/1 in fractional odds. The implied probability for these odds is 33.33%. In this example, the odds suggest that the player has a 33.33% chance of winning the match. This doesn’t mean that this is the player’s EXACT chance of winning the game. Instantly convert betting odds in any format. Supports decimals, fractions, American odds. The tool will also tell you how likely the event is to occur to help you know what your chances of winning are. Plus when you're away from a computer or mobile, learn how to manually convert the odds.
Whether you’re trying your luck with seemingly absurd wagers, or gambling on more probable outcomes, you have to understand the odds used so you can always work out the best returns. The three main formats are American, fractional, and decimal odds and, as touched upon, different countries have different preferences. Let’s take a look at each format in turn.
American odds (also known as Moneyline or US odds) display the favorites with a minus sign and a number indicating how much you need to stake to win $100. The odds for the underdogs have a plus sign, showing the amount you’d win for every $100 staked. For example, in this guide to NFL odds, the odds for a game between the Chiefs and Packers are:
Chiefs +3 (-110)
Packers -3 (+110)
Ignoring the -3 and +3 figures, for now, the odds of +110 for the Packers indicates a lower probability of them winning the game. As such, it’s in the bookmaker’s interest to offer longer odds, which are more tempting. You’d win $110 for every $100 gambled on the Packers if they unexpectedly won, which would give you $210 including your original stake. If you bet on the Chiefs instead, you would need to wager $110 to take home $100, which would also win you $210, including your stake. So you’ll have to gamble more to win less on the Chiefs, hence why they are favorites.
The +3 and -3 represent the point spread. This means, to win a bet on the Packers, they would need to win the game by more than three points. To win on the Chiefs, they would need to lose by two points or less (or win the game). The point spread works as an equalizer so that betting on either team offers an almost even chance of winning, despite the clear disparity between the two teams.
Fractional odds are typically used by the UK and Irish bookmakers. These are usually written with a slash or a hyphen — for example, 7/1 or 7-1, pronounced as ‘seven-to-one’. These particular odds would mean that you win $7 for every $1 you wager. According to one soccer bookmaker, the three favorites to win the 2022 World Cup have the following odds:
France: 11/2
Germany: 13/2
Argentina 11/1
With shorter odds than the other two teams, France are the current frontrunners. And while you’d make $11 for every $2 spent on France and $13 for every $2 on Germany, you’d win $11 for each $1 you wagered on Argentina to be champions. So, say you bet $100, you’d make $550 profit on France [$100 x (11/2)], $650 on Germany [$100 x (13/2)], and $1100 on Argentina [$100 x (11/1)].
There are also reverse fractional odds, known as ‘odds-on’ prices. The bottom number of the fraction shows how many times your stake will be divided to calculate your winnings:
$1 stake divided by 2 = $0.50 winnings = odds of 1/2
$5 stake divided by 2 = $2.50 winnings = odds of 1/2
$10 stake divided by 2 = $

5 winnings = odds of 1/2
Decimal odds are used by bookmakers in Europe, Australia, New Zealand, and Canada. These are very easy to understand, and instantly allow you to distinguish between the favorites and underdogs. With decimal odds, the number represents what you’d win for every $1 wagered, including your stake. To work out the potential return, simply multiply the stake by the decimal number. For example, one Australian bookmaker offers the following odds on who will win the 2020 US presidential election:
Joe Biden: 2:00
Donald Trump: 2:00
Mike Pence: 34:00
So, if you were to put $100 on either Biden or Trump, your total return would be $200 ($100 x 2.00). As this figure includes the initial stake, your net profit is $100. Whereas, if you wagered $100 on Pence, you’d take home $3400 ($100 x 34.00), with a profit of $3300. From this, it’s obvious that Biden and Trump are clear frontrunners to be the next US president, with Pence’s long odds showing how unlikely his chances of taking office are perceived to be.
It is important to note that American, fractional and decimal odds are simply alternative ways of presenting the same information, meaning you can convert between them easily.

The odds converter tool in this page will convert odds from any of the three main formats into the other formats.
It will also calculate the relevant implied probability too.
To use it, simply enter the odds you wish to convert in the appropriate box, and then click the “Convert Odds” button. It’s as easy as that!
If you came to this page specifically looking for a tool to
convert odds, then it’s likely that you already have a
fundamental understanding of what odds are and how they work in
relation to sports betting. If this is a subject that you’re not
particularly familiar with, however, then you might want to read
the following article from our beginner’s guide to sports
betting.
Odds Conversion Math
Overview of Different Odds Formats
If you live in the United States, then simply knowing the
moneyline odds will suffice, as this is the primary format used
by the limited number of gambling sites available for US
residents. Likewise, if you live in the United Kingdom, then you
only really need to know how fractional odds work. If you live
in Europe, then the decimal format is the one that will be most
important for you to understand.
With all that being said, it’s still a good idea to be
familiarized with how each format works. Many online betting
sites will allow you to choose the format that their odds are
displayed in. Please keep in mind that the conversation may
round in their favor.. For example, most US friendly sites offer
moneyline odds of -110 when betting points spreads. If you
choose to bet in the decimal format instead, then you’ll often
be given odds of 1.90. The true conversion is 1.9091 though, so
you’ll potentially lose a small percentage of your winnings if
you bet based on their conversion.

Therefore, it can be an advantage to use the primary format
offered by an online bookmaker, which is why it pays to make
sure you understand each of the different formats. We’ve
explained them all below for you.
American Odds/Moneyline Odds
Odds in this format are expressed as either a positive number
or a negative number. When they are a positive number, the
number represents how much in winnings is paid per $100 staked.
The following examples illustrate how positive moneyline odds
work.
When they are a negative number, the number represents the
amount of money that needs to be staked in order to win $100.
The following examples illustrate how negative moneyline odds
work.
Please see our article on calculating payouts from moneyline
odds for details on how to work out the potential winnings from
wagers using this format.
Decimal Odds
This is the most popular odds format outside of the United
States and is sometimes referred to as European odds. It’s a
very simple format where the odds are expressed as a single
positive number, usually to two decimal places. This number
states how much a winning bet returns (including the initial
stake) for each unit wagered. The following examples illustrate
the decimal format in practice.
Our article explaining how to calculate payouts from decimal
odds will teach you how to work out the potential returns from
wagers placed using this format.
Fractional Odds
Fractional odds are mostly used in the UK, but lately the
decimal format has been becoming more popular. Odds in this
format are displayed as a fraction, as the name suggests. The
first number of the fraction shows how much you can win per the
second number staked. This sounds more complicated that it
actually is and the easiest way to understand this format is
simply to look at some examples.
Please note that when the second number of the fraction is
higher than the first, it means the odds are less than even
money. This is referred to as odds on (as opposed to odds
against), and is the equivalent of when moneyline odds are a
negative number or when decimal odds are a number less than 2.
Odds Conversion Math
Our conversion tool is the easiest way to change odds between
formats but there will be times when you don’t have access to
it. When you’re at a Las Vegas sportsbook or a high street
bookmaker, you may need to be able to do these conversions in
your head. For this reason, we’ll run through the math required
to convert each format into all of the other formats.
Converting Moneyline Odds
To Decimal
The calculations required to convert from moneyline odds
changes depending on whether the odds are positive or negative.
To convert positive odds into decimal odds, the following
calculation is required.
Example: Converting +175
(+175 + 100) / 100 = 2.75
For negative odds, we ignore the minus symbol and use the
following formula.
Example: Converting -110
(110 + 100) / 110 = 1.909
To Fractional
When converting from the moneyline format into the fractional
format, the calculations again depend on whether the odds are
positive or negative. To convert positive odds, you simply
create a fraction by putting the relevant number over 100 and
then simplifying the fraction if possible.
300/100 is simplified to 3/1
To convert negative odds, you create a fraction by putting
100 over the relevant number (ignoring the negative sign).
Again, you then need to simplify the fraction if possible.
100/110 is simplified to 10/11
Converting Decimal Odds
To Moneyline
The method required to convert the decimal format over to the
moneyline format is dependent on whether the odds are greater
than 2.0 or not. We’ll look at how to convert odds of 2.0 or
less first. To start with, you have to carry out the following
calculation.
After doing this calculation, the odds are rounded and a
negative sign must be added.
100 / (1.95 – 1) = 105.25
To convert odds of greater than 2.00, you must start with the
following calculation.
To convert odds of greater than 2.00, you must start with the following calculation.
You then add a positive sign to the result, as shown in this
example.
(2.45 – 1) x 100 = 145
Positive sign added = +145
To Fractional
The first step in converting from decimal to fractional
format is to create a fraction by using the formula.
This will often create a fraction that includes a decimal,
which isn’t a proper fraction. To overcome this, the next step
is to multiply both sides of the fraction by 100. Finally, the
fraction needs to be simplified. The following example
illustrates this better than any written explanation can.
(1.45 – 1) / 1 = 0.45/1
Multiply both sides by 100 = 45/100
Simplified = 9/20
Converting Fractional Odds
Before we get into the math involved here, you need to
understand the terms numerator and denominator. In this context,
the numerator is the first number in the fraction and the
denominator is the second number in the fraction. With odds of
2/1, for example, 2 is the numerator and 1 is the denominator.
To Moneyline
There are two methods needed for converting from the
fractional to the moneyline format. The first is for when the
numerator is greater than the denominator. The following formula
needs to be used in the beginning.
A positive sign then needs to be added to create the
moneyline odds, as per the following example.
Decimal To American Odds Excel Formula
Example: Converting 6/4(6 / 4) x 100 = 150
Positive sign added = +150
The second method is for when the denominator is larger than
the numerator. In these cases, the following formula needs to be
used.
A positive sign then needs to be added to create the correct
moneyline odds. This is illustrated in the following example.
100 / (2 / 5) = 250
Negative sign added = -250
To Decimal
Converting odds from the fractional format to the decimal
format is relatively simple and it requires just the following
formula.
(11 / 10) + 1 = 1.10
Implied Probability Explained
Implied probability in relation to sports betting is
basically the implication of the odds as it relates to the
chances of an outcome happening. We’ll cover this in more detail
shortly, but first let’s look at how to calculate it. It’s
easiest to determine implied probability from odds in the
decimal format, using the following simple formula.
How To Convert Decimal Odds To American Odds
What this example shows us is that the implied probability of
2.50 odds is 0.40 (or 40% if expressed as a percentage). This
means that odds of 2.50 on any possible outcome imply that the
chance of that outcome happening is roughly 40%. So if, for
example, a tennis player is at 2.50 to win an upcoming match,
the implication is that he has a 40% chance of actually winning
that match.
Decimal Odds To American Odds
You can read more about implied probability in this article on probability in sports betting. The article also
covers expected value, which is a related topic that you should definitely learn about if you want to be a
successful bettor.
Understanding Vig
When looking at the odds set by bookmakers, it’s important to
recognize that implied probability is rarely an entirely
accurate reflection of the real chances of a wager winning. This
is because bookmakers always try to set the odds at levels that
are lower than they actually should be in relation to real
probability. If their view was that a soccer team had a 60%
chance of winning a match, for example, they wouldn’t offer odds
that exactly reflected that chance. Their odds would be lower,
as this is how they make money successfully.
Us Odds To Decimal
By reducing the odds relative to the probability of an
outcome happening, bookmakers effectively charge a commission
for every wager they take. This commission is known as vig,
which is short for vigorish. It can also be referred to as the
overround or juice. It’s similar in some respects to the house
edge in casino games and it’s basically what gives the
bookmakers an advantage over their customers.
What sets the bookmakers’ advantage apart from the casinos’
advantage is that, unlike the house edge, it can be overcome. In
order to overcome it, though, you first need to understand
exactly how vig works and the effect it has in sports betting.
You should visit our page on the subject of how bookmakers make
money, as this is all about the methods that bookmakers use to
ensure they are profitable. Charging vig is one of these methods
that we explain thoroughly.
