The rest of the world uses Decimal Odds, in part because it’s easier to convert them to implied probabilities than American Odds.Decimal odds represent the amount a bettor wins for every $1 wagered.And the number represents the total return, not just the profit like American and fractional odds. The Packers would be 1.714 in decimal odds as a -140 favorite in American odds. Now, how do we calculate minus (-) odds for American odds bets? Basically, we calculate the odds for favorites. Again, negative odds show you how much to bet to win $100. So, now say the Patriots have -125 odds. This means that you have to bet $125 to win $100. Profit = (Stake/Odds) x 100. Profit = (Stake/Odds) x 100.

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.

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.

Sports Odds Payout Calculator

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.

(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.

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.

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.

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.

Moneyline bets present the most straightforward way to wager on a sports contest. A moneyline wager simply asks the bettor to choose which team will win a game, with no point spread involved.

The payout odds on the favorite and underdog can differ significantly on a moneyline bet. Using a moneyline calculator breaks down the math on the odds, which allows bettors to assess the true value on each side.

The following page includes the GamingToday.com MoneyLine Calculator, as well as several valuable tables and graphs designed to help bettors gain an edge with moneyline bets.

What Is A Moneyline Bet?

Legal US sportsbooks generally present several different ways to wager on sports. Moneyline bets represent just one of several different wagering options, which include point spread, totals, parlays, and in-game betting.

Moneyline Bets

A moneyline wager allows the bettor to put a bet on which team or athlete will win a contest, straight up. The moneyline underdog will always pay out at better odds than the favorite.

Skilled bettors look for value on moneyline bets by evaluating teams that have a better chance of winning than the implied probability of the odds might dictate.

Moneyline favorites are listed with “-” odds, and the underdog is listed at “+” odds.

For example, here’s a look at a line offered by PointsBet on Game 1 of the 2020 World Series:

American Odds

PointsBet sets the Los Angeles Dodgers as the favorite in the game, with -165 moneyline odds. To calculate “-” odds, divide 100 by the odds, then multiply that quotient by the amount you bet.

For example, suppose you want to calculate how much profit a $50 bet on the Dodgers would yield. First divide 100 by 165 (without the “-”), which yields 60.6. Then multiply that number by your $50 bet to arrive at the profit (60.6*$50=$30.30).

8 5 Odds Payout

A $50 bet on the Dodgers at -165 odds would yield $30.30 in profit. The $50 wager would return $80.30 to the bettor ($30.30 profit plus the original $50 bet).

To calculate “+” odds, divide the odds by 100 and multiply that product by the amount of the wager.

A $50 bet on the Tampa Bay Rays, for instance, would calculate as 140/100 (which yields 1.4), multiplied by $50 (1.4*$50=$70). A winning $50 moneyline bet on the Rays returns $120 total to the bettor ($70 profit plus the original $50 bet.)

Decimal Odds

Decimal odds can be used to make a simple calculation of odds multiplied by wager amount to arrive at the total amount returned to the bettor.

The -165 odds on Los Angeles, for example, convert to 1.6061 decimal odds using the Gaming Today moneyline calculator. Multiplying that by a $50 bet yields $80.30, and subtracting the original bet amount yields the profit earned ($80.30-$50=$30.30).

What Is A Moneyline Calculator?

The Gaming Today Moneyline Calculator allows for quick calculations for any wager amount and payout odds. Using American, decimal, fractional, Hong Kong, Indonesian, or Malay Odds, you can input the odds and the amount of a wager and see the payout that would come if the bet is a win.

While it’s valuable to understand and be able to calculate favorite and underdog Moneyline odds for all of the different odds notations, the moneyline calculator can save a significant amount of time and energy.

One of the most important features of the Gaming Today Moneyline Calculator is the Implied Probability feature.

For any favorite or underdog input, the calculator produces the implied probability of that team winning. Astute bettors can use the calculator to find teams that have a higher actual win probability than the implied probability dictated by the odds.

The “To Win” window displays the amount of profit yielded by any combination of odds and wager amount. To calculate the return to the bettor, add the “To Win” number to the original amount of the wager.

How To Use The Moneyline Calculator To Place A Sports Bet

Suppose you wanted to put the Gaming Today Moneyline Calculator to work to decide how you wanted to bet on Game 1 of the 2020 World Series. Here’s another look at the lines offered on that game by PointsBet:

To calculate a $50 moneyline wager on the Tampa Bay Rays, input $50 in the “Bet Amount” window and put “+140” in the “American Odds” window. Hit enter or click on the “Convert Odds” button and see how the moneyline calculator converts that information into several different useful categories.

The calculator converts the “+140” odds into all of the different notations you might see used by a sportsbook.

The +140 American odds convert to 2.40 decimal odds, 7/5 fractional odds, 1.40 for Indonesian/Hong Kong odds, and -0.7143 Malay Odds. A tool like our moneyline calculator can be a crucial component of a betting strategy when evaluating odds at sportsbooks that use different notations.

The “Implied Probability” output tells you that at +140 odds, the Rays have a 41.67% implied probability of winning. A skilled bettor will take that bet if they think Tampa Bay’s actual chance of winning the game is higher than that.

The “To Win” output yields the profit produced if the Rays win. A $50 winning bet on the Rays yields $70 in profit and a $120 total return to the bettor ($70 profit plus the $50 original bet).

Calculating Positive And Negative Moneyline Odds

The math used in calculating the payout on a moneyline is pretty simple. It is one of the most important first steps to understanding sports betting and is crucial to success. Below is a graph of profit won on $100 bets for negative odds. Note that it is a curve that approaches, but will never get to $0. Even -1,000,000 odds still yields some profit from a win:

And here is a graph of profit for positive numbers. The really important difference is that the line is linear. as the odds increase, so does the profit. That goes on forever.

Looking at the odds offered by the sportsbook, note whether they are negative odds (for example -110) or positive odds (for example +120). The calculation changes based on if it is a positive or negative odd. Below we work through an example of a bet of $100 at -110 moneyline odds. It is important to notice that multiplying by -1 is required to give us the positive payout:

PAYOUT = BET AMOUNT / (-1 *MONEYLINE ODDS / 100)

300 To 1 Odds Payout Calculator Free

So that looks like:

$90.91 = $100 / (-1 * -110/100)

That also means that you will be returned that amount AND your original bet, meaning you now have $190.91. Let’s work another negative example of a $100 bet at -150:

$100 / (-1 * -150 / 100) = $66.67

Now let’s work through a positive money example. Let’s say you bet $100 at +120

PAYOUT = BET AMOUNT * ODDS / 100

That looks like:

$120 = $100 * 120 / 100

In that case, you are returned your original bet plus profit, so you now have $220.

What Is Line Movement?

Sportsbooks make money by setting lines that bring in an appropriate amount of wagers on both sides of a bet. The house offers odds that factor in a cut of overall wagers, known as vig, that goes to the sportsbook.

In the World Series Game 1 example from above, if 90% of bets come in on the Dodgers, the sportsbook stands to lose big money if Los Angeles wins. A Tampa Bay win in that situation is even more disastrous for the sportsbook.

If the bets coming in on a game are too one-sided, the line on the game will start to move to try to prompt more bets for the other side. It’s important to remember that sports betting isn’t a zero-sum game, and you’ll be losing in the long run even if you win 50% of the time.

Legal Online Sports Betting In The US

A federal mandate known as the Professional and Amateur Sports Protection Act (PASPA) was overturned in May 2018, giving US states the legal clearance to offer state-regulated sports betting. Several states now offer both retail and online sports betting, including New Jersey, Pennsylvania, Nevada, Illinois, Indiana, Colorado, and several others.

The top online sport betting brands in the US include the following:

DraftKings Sportsbook

One of the biggest brands to emerge in the booming online sports betting industry, DraftKings Sportsbook offers mobile sports wagering in eight states. The sportsbook offers every imaginable kind of wager across multiple sports.

A collaboration between FOX Sports and The Stars Group, the FOX Bet brand operates online sportsbooks in New Jersey, Pennsylvania, and Colorado.

The moneyline odds at FOX Bet can vary greatly versus some of its competitors, and bettors using a moneyline calculator tool gain a significant edge versus players that don’t.

Moneyline Calculator FAQs

Yes. More than a dozen states either currently offer online sports betting or have a launch of mobile sports betting products pending.

New Jersey, Nevada, and Pennsylvania represent the three biggest online sports betting markets in the US. Other states with legal online sports wagering include Colorado, Illinois, Indiana, Iowa, West Virginia, and a few others.

The Gaming Today Moneyline Calculator can be used as a valuable resource on any moneyline bet. It’s especially useful for evaluating the implied probability of winning and payout odds.

The moneyline bet calculator’s ability to display odds across multiple notation formats (American, Decimal, Fractional, Indonesian/Hong Kong, and Malay odds) allows bettors to compare lines across sportsbooks that use different notations.

Even if you’re a veteran sports bettor, running every bet you’re considering through the calculator provides significant benefit.

Yes. Nothing in the terms and conditions of any US legal online sportsbooks prohibits the use of a moneyline calculator.

The calculator provides computations that any person could produce with pen and paper but in a much faster and more efficient manner.

For “+” American odds, divide the odds by 100 and convert that quotient into a fraction. To convert +160 into fractional odds, for example, divide 160 by 100 (160/100) and reduce that fraction to the lowest whole number denominator. American odds of +160 would convert to 8/5 fractional odds.

For “-” American odds, divide 100 by the odds and convert to the simplest form fraction. For -160 odds, for example, the calculation looks like 100/160, which reduces to 5/8 fractional odds.

To convert “+” American odds to implied winning probability, the formula looks like this:

100 / (“+” American odds + 100)*100 = implied probability

For example, +160 odds would be calculated as 100/(160+100)*100. This converts to 100/260*100, which ends up yielding a 38.46% implied probability.

To convert “-” odds, the formula looks like this:

“-” odds / (“-” odds + 100)*100 = implied probability

For instance, -160 odds would translate to 160/(160+100)*100, converting to 160/260*100, which yields a product of 61.54. The implied probability of -160 odds is a 61.54% chance of winning.

Several online sportsbooks offer comprehensive coverage of sports and ways to bet. Some of the best choices for online sports betting in the US include DraftKings Sportsbook, FanDuel Sportsbook, PointsBet, FOX Bet, and BetMGM.
