Explain Vegas Odds
Betting Odds Explained. Having never been explained betting odds can be intimidating. They come in different formats, and sometimes seem to work counter-intuitively. You can trust our team of experts. Betting guides meaning of odds. Horse Racing Odds Explained What Do Horse Racing Odds Mean? If you see a horse listed at 7-2 odds for the first time, or a mutuel payoff amount of $5.00, you may not quite understand what that means if you want to place a bet. Sometimes, Vegas odds are reflective of bettors’ behavior. If they’re wagering a lot of money on one player, the odds are going to change in his favor. Still, in most cases, Vegas odds are as close as possible to true probability. The thing is that the oddsmakers employed by big-name Las Vegas sportsbooks are really good at their job.
To properly understand sports betting, you need to understand
odds. They are an integral part of any sports wager, and they are used
to determine whether a wager is worth making or not. The
potential payout of any wager you place is calculated using a
combination of the relevant odds and your stake.
On this page, we explain about odds in some detail. We define
exactly what they are and the role they play. We also look at
the three different formats in which they can be expressed, and
explain why odds on the same outcome can vary with different
bookmakers.
What Are Odds?
In sports betting terms, odds basically serve two purposes.
First, they are used to calculate the payouts of winning wagers.
Every time you place a bet with a bookmaker, you’ll be offered
odds at the time, which impact how much you can win. The higher
they are, the more you stand to win relative to your stake.
Second, odds also reflect the likelihood of any particular
outcome happening. The more likely an outcome, the lower they
will be. This makes perfect sense, as you would expect to win
less when betting on an outcome that’s likely than when betting
on an outcome that is unlikely.
Imagine a tennis match where the player ranked number one in
the world is pitted against the player ranked 137th. It stands
to reason that the best player in the world is going to be
considered more likely to win than his opponent. Therefore, a
wager on his winning would have very low odds; a wager on his
opponent winning would have much higher odds.
This is a somewhat simplified explanation, but it gives a
general idea of the role of odds in sports betting.
Different Odds Formats
As you can see, the fundamental principle behind odds is
really quite straightforward. Things are slightly complicated by
the fact that there are three different formats of odds as
follows:
- Moneyline/American Odds
- Decimal Odds
- Fractional Odds
Chances are, at some point, you’ll encounter each of these
formats. For this reason, it pays to be familiar with each one.
They all work in essentially the same way–basically just
different ways of expressing the actual odds for any particular
wager.
Moneyline or American Odds
Moneyline odds are also known as American odds, and this is
the format most commonly used in the United States. They can be
displayed as either a positive or a negative number. A positive
number expresses how much a correct wager of $100 would win,
while a negative number expresses how much you would need to
stake in order to win $100.
If you saw odds of +150, you would know that a $100 bet could
return $150 in winnings, plus the initial stake of $100. If you
saw -150, you would know you need to stake $150 to return $100
in winnings, plus the initial stake of $150. An even money wager
(where you stand to win an amount equal to your stake) is
expressed as +100.
Decimal Odds
Decimal odds used to be associated mostly with mainland
Europe, Canada, and Australia. However, they have now largely
become the standard at most online bookmakers with the exception
of some US betting sites. This is because they are the most
straightforward of the three formats and are expressed simply as
a single positive number, typically to two decimal places.
Betting Odds Explanation
The number shows how much the total payout will be, including
the original stake per unit staked. For example, a winning bet
at 1.5 would return a total of $1.50 for every $1 staked. A
winning bet at 2.25 would return a total of $2.25 for every $1
staked. An even money bet is expressed as 2.00.
Fractional Odds
Fractional odds are the traditional format used in the United
Kingdom, although decimal odds are slowly taking over.
Calculating potential profits and payouts with this format can
be a little tricky, certainly to start with, but the basic
principle isn’t as complicated as it might seem. As with
moneyline odds, fractional odds show how much potential profit
you can make. To calculate the total potential payout, you have
to add your original stake.
As the name suggests, these odds are displayed as a fraction.
A simple example is 3/1, which is said as “three to one”. 5/1 is
said as “five to one”, and so on. With 3/1, you can win three
units for every one unit staked, and with 5/1 you can win five
units for every one unit staked. 1/1 is even money, so you can
win one unit for every unit staked. As you can see, this is
quite straightforward so far.
Things get slightly more complicated, because this format also
includes examples such as 6/4, 11/10, and 5/2. The math involved
is thus not always so simple. With 6/4, you can win six units
for every four units staked, which is equal to 1.5 units per
unit staked. With 11/10, you can win eleven units for every ten
units staked, or 1.1 units per unit staked.
Whenever the first number is larger than the second, this is
said to be “odds against.” These are basically the equivalent of
positive moneyline odds in that the potential profit is greater
than the amount staked. Things get even more complicated as
there are also “odds on” odds. These are the equivalent of
negative moneyline odds in that the potential profit is less
than the amount staked.
An example of odds on is 1/4 is said as “four to one on”. 4/7
is “seven to four on”, and so on. With 1/4, you can win one unit
for every four units staked, and with 4/7 you can win four units
for every seven units staked.
Converting Odds Formats
If you ever want to convert odds from one format to another,
there are some reasonably straightforward calculations you can
do. We can save you the bother, however, as we offer a useful
tool which will automatically convert any odds from one format
to another. You can find this tool on the following page.
Why Odds Vary on the Same Outcome
For a lot of wagers on sporting events, you’ll see that
different bookmakers offer different odds. For example, one
might have a football team at +130 to win a match, while another
might have the same team to win the same match at +120. To
explain this, we expand on a statement made earlier.
When we said that odds reflect the likelihood of a particular
outcome happening, it would have been more accurate to say that
they reflect how likely a particular outcome will happen in the
view of the bookmaker. Predicting how likely any outcome is in a
sporting event isn’t an exact science, and it essentially comes
down to a matter of opinion.
This is why the odds in sports betting are variable, because not
all bookmakers will have exactly the same view on how likely a
particular outcome is. Odds can also be affected by other
factors, such as the amount of money a bookmaker has taken on a
particular market. What this means is that the odds that a
bookmaker sets for a wager aren’t always an accurate reflection
of the true likelihood of the relevant outcome happening.
Therefore, it’s possible to put the odds in your favor when
betting on sports. If you’re able to correctly predict the
outcome of sporting events often enough, you can consistently
turn a profit. It’s not easy, but if you can combine your sports
knowledge with an understanding of certain key aspects of
betting, it can definitely be done.
Odds are one of those key aspects, and you hopefully now
understand how they work and why they vary. You should also
understand why the use of odds is the main reason why bookmakers
make money, which we explain in the next article.
- Learn About
Learning how sports betting odds work can be intimidating at first, but our guide will teach you how to read odds in no time! This primer is designed for beginners who are curious about common wagering practices and terms.
Learn to Bet on Sports & Gamble Online & Offline
For starters, you will need somewhere to place bets. If you are in Vegas, great! You can bet at one of the sportsbooks in their casinos. As more and more states pass laws to legalize sports betting, you will also be able to place wagers at local casinos in your area. You could also find a local bookie to bet through, but we recommend betting online.
How Online Betting Works
We have an excellent list of the top places to bet online (that take U.S. customers). If you are looking to maximize your first deposit, we also have a great comparison of the best sportsbooks signup bonuses for you. Once you’ve read the primer below on reading the odds, you will have no problem navigating these sites.
Las Vegas Sports Betting at the Ticket Window
Betting sports in Vegas is likely going to be the option with the biggest learning curve. You will understand the odds after reading this article, but there are a few other rules and common practices you want to be familiar with that are specific to Vegas.
Many books now offer their own betting apps that make this process a little bit easier, however, the drawbacks are that you must make a deposit upfront for how much you want to bet with, plus you don’t get free drink tickets when you place bets on the app. We’ll step through how you would place a bet in person at the ticket window.
Step-by-Step Guide to Placing Sports Wagers in Vegas
“I’ll take number 403, Cowboys -8, for $110 straight up.”
- Use the rotation number/numbers and the name of the team/teams you want to bet on. The rotation number appears to the left of each team (see image above) and is used as a unique identifier so that there is no confusion about what you want.
- State the amount you would like to bet. This is how much you are wagering, not how much you want to win. Most books use -110 odds (more on this later), so if you want to win $100, you’d state $110 as your wager amount.
- Indicate the type of bet you are placing. For individual bets, just say “straight” or “straight up”, otherwise you will need to explain that you are taking a parlay or some other bet type.
- Repeat as necessary.
How to Read Sports Betting Lines
There are nearly infinite ways to bet sports. If you can think of something to bet on, there is a good chance you can find somewhere to bet on it. What we are going to focus on is the most common types of wagers: point spreads, over/unders (totals), and money lines.
What Does the Plus (+) and Minus (-) Mean in Sports Betting?
One of the first and most important aspects of sports betting every new player must learn is what the different symbols mean. A plus or a minus can mean different things in different situations. They are used for both point spread and money line betting, as well as for the price/juice of each bet.
This is explained in more detail below, but the most important thing to be aware of is that negative numbers represent favorites, while positive numbers represent underdogs. The same is true whether you are looking at a spread or a moneyline, but how these numbers are used is very different. You also need to know that prices on spreads/totals do not impact who/what is favored, it is used to determine how much the bet pays out. Read on for the complete explanation of each of these concepts.
Point Spreads Explained
Betting Odds Explained +100 100
The point spread is the projected number of points that separate two teams. A game with a spread will have a favorite (the team expected to win) and an underdog (the team expected to lose). A favorite “gives” points and is identified with a minus sign next to their point spread. The underdog “gets” points and is identified with a plus sign next to their point spread.
Teams | Spread | Price/Vig |
---|---|---|
New York Jets | +7 | -110 |
New England Patriots | -7 | -110 |
In the example above, the point spread is 7 points. Patriots are favored by 7 points against the Jets.
If you bet on the Jets +7, they must either win the game outright or lose by 6 points or less. If they lose by exactly 7 points, the bet is considered a push and is canceled.
If you bet on the Patriots -7, they must win the game outright by more than 7 points. If they win by exactly 7 points, it’s a push.
Bet Prices: What Does -110 Mean? If I Bet $100, What do I Win?
The 3-digit numbers to the far right are the listed prices for these bets. This is also called the odds, vig, or juice. An easy way to think of it is the amount you must risk to win $100 on this wager. In our example, -110 means you must risk $110 if you want to win $100. -110 is pretty standard, but you will find different options. We will cover those in more depth when we talk about money lines. The price of the bet has no impact on which team is favored. Only the plus or minus on the point spread matters. This is handled differently when you bet strictly on the moneyline.
What is the Money Line? (How Moneyline Betting Works)
A moneyline bet is on a team to win the game outright (without a point spread) at an adjusted cost. Just like with point spread betting, the favorite will have negative odds, while the underdog will have positive odds. The difference here is in the price or payout depending on which team you take.
Teams | Moneyline |
---|---|
New York Jets | +240 |
New England Patriots | -280 |
A favorite (e.g. Patriots -280) on the money line works just like our bet price example above. In our new example, the Patriots are listed at -280, meaning you would need to risk $280 for a return of $100 on them. It follows that a winning bet on the Pats pays $100 (plus your initial investment of $280 back). This added risk is why betting the spread is usually more popular, especially on favorites.
Underdogs (e.g. Jets +240) work a bit differently. Instead showing how much you need to risk to win $100, this line tells you how much you stand to win on a $100 wager. That means if you bet $100 on the Jets, and they win, you would win $240. If the Jets lose, you are only out your original $100 wager.
Totals: What Over/Under Means in Sports Betting
Explain Las Vegas Sports Odds
The terms “total” and “over/under” are synonymous when placing wagers. This type of bet is on the sum of the points scored by both teams in a game. The bookie sets the number for the total, then you predict whether they will score more or less points than the set number.
Teams | Total | Price/Vig |
---|---|---|
New York Jets | Over 42.5 | -105 |
New England Patriots | Under 42.5 | -115 |
The over/under in this example has been set at 42.5. If you project the Jets and Patriots to combine to score more than 42.5 points, you would place a wager on the over. If you think they will score less than 42.5 points, you would bet the under. Let’s say the final score of this game is Patriots 27, Jets 24. Which bet would lose and which bet would win? The sum of all points scored is 27 + 24 = 51, so an over bet wins and an under bet loses.
You may also note the bet price is not -110 like we have seen before. It is common practice by sportsbooks to adjust prices on or around key numbers for spreads and totals, especially in football.
