When you bet for the underdog, it is called betting 'against the odds.' For example, if odds are 3/1 for the Cowboys this Sunday, then it is three times more likely that they will lose than win. Odds of 3-1 indicate that if you bet $100, you will win $400, the original amount of your bet plus the profit.

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. If you’re looking for the best odds at an online sportsbook, be sure you check out Bovada.

1. Typically, a point spread has odds of -110 for either side of the bet. In the example above between the Cowboys and Giants, the point spread is 4.5 points, while the odds are -110, meaning you would have to wager $110 to earn a profit of $100, or a profit of $0.91 for every dollar you bet.
2. Betting Odds Explained Odds are calculated according to the probability that something specific may or may not happen. In other words, let’s say the likelihood that Manchester United will win over Liverpool, or how likely that match will end in a certain amount of goals.
3. Sports betting is a rapidly growing industry in the United States, particularly after a 2018 ruling by the Supreme Court that opened the door to legalized operations on a state-by-state basis.
4. Using the +120 odds, it shows us that a $100 bet on that outcome would pay out $120 in profits. Again this can easily be converted into smaller or larger size bets. A $10 bet on +120 odds would pay out $12 in profits.

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.

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.

Explaining Betting Odds Ratio

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.

Explain Betting Odds In Horse Racing

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.

• Betting odds tell you how likely an event is to happen
• They also tell you how much money you will win
• However, at first, they may seem confusing and complex
• Our comprehensive guide takes you step-by-step to explain them

If you’re new to betting, one of the first things you should do is learn how betting odds work. It’s critically important because it allows you to understand how likely an event is to happen, and what your potential winnings will be. At first, it may appear confusing, however, read our guide and let us explain it to you.

In gambling, odds represent the ratio between the amounts staked by parties to a wager or bet. Thus, odds of 3 to 1 mean the first party (the bookmaker) stakes three times the amount staked by the second party (the bettor).

What is Probability?

The most basic level, betting provides you with the ability to predict the outcome of a certain event, and if your prediction is correct, you will win money. For any given event, there are a certain number of outcomes. Take rolling a dice for instance. If someone rolls a dice, there are six possible outcomes. Therefore, if you bet that the person rolls a ‘one’, there is a 16.67% chance that will happen. What betting odds merely do is present how likely the event is to happen. Bookies most frequently in the UK do this as a fraction, i.e. 4/7, whilst the vast majority also offer the ability to view them as decimals. Again, let us talk you through them. All will become clear.

Using Betting Odds to Calculate Probability

Whenever you see two numbers separated by a trailing slash, i.e. 10/1, this is known as fractional odds. From this, you can calculate how likely a given event is to happen with a calculation. For ease of explanation, let’s replace the numbers with letters i.e. 4/1 becomes A/B. Here is the calculation: Probability (%) = B / (A+B).

• 9/1 can be calculated as 1 / (9 + 1) = 0.10– There is a 10% chance that the event will happen.
• 4/1 can be calculated as 1 / (4 + 1) = 0.20 – There is a 20% chance that the event will happen.
• 1/1 can be calculated as 1 / (1 + 1) = 0.50 – There is a 50% chance that the event will happen.
• 1/4 can be calculated as 4 / (4 + 1) = 0.80 – There is a 80% chance that the event will happen.

Hooray! We’re making progress. Given a fraction, we can now tell how likely (the probability) what we’re going to bet on will happen. Now let’s figure out how much money can be won using betting odds.

Using Betting Odds to Calculate Winnings

Betting odds allow you to calculate how much money you will win if you make a bet. Let’s use the same examples as before, with the same replacement of numbers for letters, i.e. 4/1 becomes A/B. Quite simply, for every value of B that you bet, you will win A, plus the return of your stake.

• 9/1 for every £1 you bet, you will win £9.
• 4/1 for every £1 you bet, you will win £4.
• 1/1 for every £1 you bet, you will win £1.
• 1/4 for every £4 you bet, you will win £1.

What About Decimals?

Decimals are far more common on exchanges, such as Betfair, but all leading betting sites do give you the option to view betting odds in this format. 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.
• 4.0 can be calculated as (4.0 * £10 stake) – £10 stake = £30 winnings.
• 2.5 can be calculated as (2.5 * £10 stake) – £10 stake = £15 winnings.
• 1.25 can be calculated as (1.25 * £10 stake) – £10 stake =£2.50 winnings.

Decimal Odds Versus Fractional Odds

In truth, one isn’t better than the other but there is certainly a trend emerging towards decimal odds. Historically fractional odds were used in the UK, especially on racetracks and on the high street. There are two key differences. Generally, decimal odds are easier to understand. Based on this, there has a movement to attract more people to horse racing by making it more accessible to the average punter. Ten years ago, if you were going to Cheltenham, all the odds would be displayed as fractional odds. Now, they’re largely all in decimals. Don’t hesitate to check out our exclusive Premier League Betting Offers !

The second difference between the formats is that fractional odds only represent winnings, and do not include the returned stake compared to decimals which do include the stake. The transition from fractional odds to decimals largely kicked off with the growing popularity of the betting exchanges such Betfair. For odds to change slightly, it’s really difficult to marginally increase or decrease the probability without creating large fractions which are hard to compute for the punter.

In Summary

Betting odds represent the probability of an event to happen and therefore enable you to work out how much money you will win if your bet wins. As an example, with odds of 4/1, for every £1 you bet, you will win £4. There is a 20% chance of this happening, calculated by 1 / (4 + 1) = 0.20.
