They are an alternative to seeing betting odds in the fraction format, and in our opinion, are easier to work out. Here is the calculation: winnings = (odds. stake) – stake. Let’s illustrate it with some examples. 9.0 can be calculated as (9.0. £10 stake) – £10 stake = £80 winnings.

To convert decimal odds to fractional, subtract 1.00 and then find the nearest whole integers (so 3.75 - 1.00 becomes 2.75/1, or 11/4). To convert moneyline odds to decimal, if the moneyline is positive, divide by 100 and add 1. If it is negative, divide 100 by the moneyline amount (without the minus sign) and add 1. For example: In the case of 1/10 short odds (1.10 in decimal form), you could win £1 for every £10 you bet. Therefore, a winning £10 bet would result in £1 in winnings, amounting to a return of £11 (your £1 winnings plus your £10 stake). How to read betting odds. Betting odds are most commonly presented as a fraction or a decimal in the UK.

If you’re going to bet on sports, you need to understand the odds before you put any cash down. There’s no way for you to know the risk involved in your particular wager or the potential payoff unless you know how betting odds work.

Let’s take decimal odds of 4.5, this is the equation: 4.5 – 1 = 3.5 35/10 - 7/2. If the decimal price is 1.25, you convert it into fractional odds like this: 1.25 – 1 = 0.25 25/100 - 1/4. Here’s a list of some of the most common fractional odds and their decimal equivalents (for a more in-depth list click here). A wager that there will be over or under 215.5 points scored in the match, with equal returns for either outcome (an $11 stake will return $10.01 in total). NB: In this example, the line betting and total betting is cast at a decimal (e.g. 3.5) this means there is zero chance that the line can be.

It’s essential to understand that odds are a determination of how a specific event may play out. They are not saying that the event will end in the manner predicted. They predict the likelihood of an outcome.

Those wagering on the favored team usually do so at a disadvantage, while those wagering on the underdog are given an edge. Sportsbooks do this in an attempt to even out the bets so that there’s an equal amount of cash placed on each team.

When wagering, you’ll find that there are three basic ways that odds are listed:

Odds Conversion Guide

To convert decimal odds to fractional, subtract 1.00 and then find the nearest whole integers (so 3.75 - 1.00 becomes 2.75/1, or 11/4).

To convert moneyline odds to decimal, if the moneyline is positive, divide by 100 and add 1. If it is negative, divide 100 by the moneyline amount (without the minus sign) and add 1.

To convert fractional odds to decimal, divide the first figure by the second figure add 1.00 (so 11/4 = 2.75, then add 1.00 = 3.75).

Fractional Odds

• Used mainly in the UK and in international horse racing. Becoming less popular online.
• Tell you the amount of profit relative to your stake if you win your bets.
• For example, if you bet £10 at odds of 3/1, you receive £30 profit if you win.

Decimal Odds

• Common around the world but especially in Europe. Standard on betting exchanges such as Betfair.
• Convey the total amount you will receive if you win, including the return of your stake.
• For example, if you bet £10 at odds of 3.75, you will receive £37.50 in total if you win.

Moneyline Odds

• Used by most US bookmakers.
• Based on a straight single bet (on a single outcome, without a points spread)
• If the moneyline is positive, the amount quoted is the amount you would win on a $100 bet.
• If it is negative, the amount quoted is what you would need to bet to win $100.

American

U.S. odds are reflected in the moneyline or line. They’re expressed in whole numbers with the number for the favored team showing a minus and the number for the team that is not favored having a plus in front of it.

Here is a moneyline for football:

This betting line favors the Colts. Indy is listed at 2:1. That means for every $2.00 bet the payout would be $3.00. That includes the $2.00 you wagered plus a profit of $1.00. If you take the Bears, the odds would be 1:4. On a $1.00 bet Chicago, which is the underdog, would pay a total of $5.00. That includes the $1.00 bet and the $4.00 payout.

The bettor always gets a bigger payout when they assume a greater risk. The more the risk, which would reflect the unlikely chance of something happening, the more you profit if the bet is won. Consider that a team that’s listed at -200 has a 66.66% chance of winning, while a team at +400 has a 20% chance of victory.

Fractional

Fractional odds, which are also known as English odds, are a bit easier to understand. If the same NFL game were listed using the fractional system it would look like this:

With this type of listing, the first number in the fraction, the numerator, is the amount you would wager and the second number, the denominator, is the payout amount. The payouts and risk in this example are exactly the same as that in the American example, with the Colts paying a $1.00 profit for every $2.00 bet and the Bears offering a $4.00 profit for every $1.00 wagered.

Decimal

You’ll find decimal odds used most often in Europe and for this reason they are known as European odds. These may be the most confusing to American bettors because the math is hidden.

Once again using the same example from the NFL, the decimal odds would be displayed in this manner:

In this system, the smaller the number the less risk involved and the better the chances are that a team will be victorious. To understand how much you will win, you would multiply the amount wagered by the betting line.

In this example, on a $1.00 bet on Chicago you would get back a total of $5.00 and on a $2.00 bet on the colts, you’d realize $3.00. As you can see, regardless of the format of the betting lines, the payout is the same.

Odds are Skewed

Betting odds can be given in various ways. The important thing to understand is they’re not “real.” They are skewed to ensure that the sportsbooks make a profit.

30 To 1 Odds Calculator

Built into the odds is the sportsbook’s commission, which is silently collected on every bet. In real life, the Colts probably have less of a chance of winning and should pay more while the Bears are even more likely to lose than the odds reflect and should also pay more.

Those are the basics to understanding odds. If you’re an American bettor, then chances are you’ll be using the U.S. version. Europe or other parts of the world, you’re going to encounter the two other types of listings.

Understanding Payouts

There are a few important aspects of sports betting payouts that you must understand in order to ensure that you’re able to take full advantage of wagering opportunities and to successfully manage your bankroll.

First we’ll take a look at some basic odds and related payouts and then we’ll consider some of the finer aspects of the payout.

You must be able to read the odds listed in order to understand how much you will make on a bet. The amount of cash that you make, your profit, is your payout. Some sports bets, such as those involving a point spread, usually pay approximate odds of 1:1. That means for every dollar wagered, you’re going to get that dollar plus another buck if you win your wager.

Here’s a look at the three ways of expressing odds that you’ll usually find listed for a favorite.

Each of these expressions of odds represents the same wager and payout. For every $2.00 bet, you win a dollar, making the total amount of cash you get back $3.00 ($2.00 bet + $1.00 payout = $3.00 return).

These are an example of the type of odds given for a team that’s not favored.

These odds tell you that for every $1.00 you bet, you’re going to get $2.00 back. The payout on this sports bet is $2.00 ($1.00 bet + $2.00 payout = $3.00 return)

Notice that you get the same amount of cash back on both bets but that you actually make double on the second wager. Never confuse “return,” which is the total amount of cash you get back when you win, with “payout,” which is actually how much you make. When it comes to sports betting you’re biggest concern is how big the payout is in relationship to how much you wagered.

The Commission

One element that many new bettors are not aware of is the commission that is paid by gamblers to bookies or sportsbooks. The commission is often referred to as vig, vigorish or juice.

This part of sports betting is important because it alters your payout, lessening it. Here’s the way it works. Vig can be readily seen in point spread betting and when you bet on the favorite using the moneyline.

Although the spread odds expressed in sports betting are 1/1, they are really approximately 1/1.10.

Here’s why:

When you place a $1.00 point spread wager, you place the dollar bet plus 10%. Thus, you would place $1.10 on a team to win $1.00. You get back your original bet, $1.10, and the one-dollar payout. But if this were a true 1/1 wager, your payout would be $1.10. What happens to the 10 cents? That’s the sportsbook’s commission.

The same can be seen with the -110 moneyline. In order to win $100 on that moneyline, you must put up $110. The way bookies make their commission on the moneyline is they charge more than they should to bet on the favorite and undercut the payout on the underdog. Thus, the vig is often hidden, but it is there.

Managing Your Bankroll

It’s important that you learn how to manage your sports betting bankroll and that means keeping track of all wagers, loses and payout. When looking at a potential payout always consider the risk involved in the bet and what percentage of your bankroll you’re willing to commit to that bet. Never risk more than 5% of your bankroll on a bet.

Understanding the payout in relationship to the amount of money risked and the total return is important to be able to manage your bankroll and sports betting business.

When Is It Too Late to Make a Bet?

When is it too late to make a bet? When the game is over. But the more complex answer has to do with how much you have to wager, what your objective is and how much you’ve lost or won.

Here are some guidelines that will help you decide when you should wager on props when the odds are becoming more favorable, diminishing odds, and when you should bet on propositions whose odds are going up or expanding:

Diminishing

There are various times when you should play props whose odds are going from being long shots to sure shots. With a diminishing odds bet, the chance of the prop being a winner is becoming more certain. Bets in this category range from 2-1 to 1-4.

Play these in the following situations:

• You’re way ahead and wagering numerous units.
• You’re behind and wagering one unit at a time.
• The game is near the end and you’re ahead. Bet one to three units.
• You’re ahead and want to preserve winnings. Bet one unit.

The above situations are all designed to make sure that you limit your loses. Along with wagering on bets that offer you low odds, make sure you bet on props about which you feel confident. The point is to give yourself the best chance of winning.

Expanding

As odds expand and go higher so do the payouts. Although commonsense tells you that these wagers are getting progressively more difficult to win, there are times that you should utilize them.

• You are way ahead and want to try to make a big score. Use only one or two units.
• It’s near the end of the game and you’re even. Go for a big play, big payout bet using one unit to try to put yourself over the top.
• The team with expanding odds is actually on a role. (It can happen).
• Bet on the defense if there are expanding odds on its side and it needs to make a big play. Use one unit.

Betting on these scenarios isn’t as foolhardy as you might think since you are limiting how much you’re going to wager, lessening your loses. Stay away from tossing a lot of cash on a bet that has expanding betting lines. If you don’t, you may see your cash diminish quickly.

The thing to remember about live sports betting is that as the game goes on and things change, the odds will also change. As they do, you can take advantage of them in various ways. Also, be careful not to bet too much.

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.

Example: Converting +175

(+175 + 100) / 100 = 2.75

1110 Offshore Dr Fayetteville Nc 28305

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

11 10 Mods

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.

What Is 11 10 Odds Calculator

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 Is 11/10 Odds

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.
