Part 1 of 3: Calculating Basic Odds

  1. Determine the number of favorable outcomes in a situation. Let’s say we’re in a gambling mood but all we have to play with is one simple six-sided die.
  2. Determine the number of unfavorable outcomes. In a game of chance, there’s always a chance that you won’t win.
  3. Express odds numerically. Generally, odds are expressed as the ratio of favorable outcomes to unfavorable outcomes, often using a colon.
  4. Know how to calculate odds against an event happening. The 1 : 2 odds we just calculated are the odds in favor of us winning.
  5. Know the difference between odds and probability. The concepts of odds and probability are related, but not identical.

A simple formula for calculating odds from probability is O = P / (1 – P). A formula for calculating probability from odds is P = O / (O + 1).

Fractional odds refer only to the profit you’ll make on your bet. Multiply your wager by the figures above and add the product on top of your original wager to get the final returns.

How Fractional Odds Work

Fractional odds (aka “British” odds, “U.K.” odds, or “traditional” odds) are popular among British and Irish bookies. They are typically written with a slash (/) or hyphen (-) and are used by some of the world’s largest bookmakers. 1


How Decimal Odds Work

Decimal odds (aka “European” odds, “digital” odds, or “continental” odds) are popular in continental Europe, Australia, New Zealand, and Canada. These are a bit easier to work with and understand. The favorites and underdogs can be spotted instantaneously by looking at the numbers. 2


How Money Line Odds Work

Money line odds (aka “American” odds or “U.S.” odds) are popular in the United States. The odds for favorites are accompanied by a minus (-) sign and indicate the amount you need to stake to win $100. The odds for underdogs, on the other hand, are accompanied by a positive (+) sign and indicate the amount won for every $100 staked. 3


What Are Five-to-One Odds?

Five-to-one odds imply that every $1 wagered could win you $5 if the bet is successful. With fractional odds, the number on the left expresses how much you win, while the number on the right reveals how much you need to stake.


Are Negative or Positive Odds Better?

Negative numbers are reserved for the favorite on the betting line and indicate how much you need to stake to win $100. Conversely, positive numbers are attached to the underdog and refer to the amount you could win if you bet $100.


The Bottom Line

If you are planning to enter the betting world, it is important to be able to understand and interpret all types of odds well.


How to Read Betting Odds

Understanding betting odds is extremely important and essential if you’re going to have a successful betting career. The good thing is that it doesn’t take much to read odds and the math isn’t too complicated. Odds in different countries differ, but we’re going to focus on American odds.


How Do Odds Work?

Basically, odds represent the favorable outcome in a game. This can be who wins, what events will happen, or combined point amounts. The three main types of odds are British, European, and American. With that said, though, it’s important to know that the type of bet differs but the payouts do not.


Sportsbook Online

Sportsbooks online are available in most U.S. states and are a great way to place your bets. Not only do they have tons of sports, but they also have so many different bets that you can place. It’s important to make sure it’s legal in your state, though, so you don’t get into any trouble.


Calculating Odds

Sportsbooks calculate odds by putting the amount that will need to be paid out to the amount of money that all bettors have paid. The sportsbooks try to keep both sides as even as possible. Not only will this save them from losing a bunch of money, but it guarantees that anyone who wins can be paid.

Who compiles odds?

Many people associate odds compiling and the pricing up of events as practices carried out solely by bookmakers or the people bookmakers employ to do so – often known as ‘odds compilers’.
The bookmaker forms a market by compiling a set of odds and the punter comes along and places their bet.


Why compile our own odds?

If you’re serious about making a success of your punting efforts then compiling your own odds is something you really ought to be doing.


What do you need to price up?

It seems to be a fairly common misconception that compiling your own odds is a highly advanced process and can only be done by those who are blessed with a superior mathematical brain. This is simply not true.


How do you compile your own odds?

Firstly you need to note that all odds should be converted into percentages and then summed for all possible outcomes.


Pricing up a simple football market

Let’s use a simple win/draw/win football market example to put this into practice. We’ll imagine that top four chasing, Tottenham are travelling to face struggling, Newcastle. We’ll start by looking at the relative home and away form of each side.


Pricing up a horse race –

Pricing up a horse race can be a bit trickier than a simple win/draw/win football market. The main reason for this is that there are less tangible statistics in a horse race. You will need to have an expert knowledge of form and be able to consider all the different factors involved in analysing both races and a particular horses’ chance.


The benefits of compiling your own odds

As we can see from both the racing and football examples above, the reason punters would choose to price up events for themselves is that it helps to both identify and exploit value.


Converting Odds to Implied Probabilities

Although odds require seemingly complicated calculations, the concept is easier to understand once you fully grasp the three types of odds and how to convert the numbers into implied probabilities.


Why Does the House Always Win?

The odds on display never reflect the true probability or chance of an event occurring (or not occurring). There is always a profit margin added by the bookmaker in these odds, which means that the payout to the successful punter is always less than what they should have received if the odds had reflected the true chances.


The Bottom Line

A betting opportunity should be considered valuable if the probability assessed for an outcome is higher than the implied probability estimated by the bookmaker. Furthermore, the odds on display never reflect the true probability of an event occurring (or not occurring).


American Style Sports Betting Odds

Most online sportsbooks will list their odds in what is called “American Odds”. There are a couple different versions of sports betting odds, but these American Odds are the most common odds used. Reading and understanding sports betting odds can bet a little confusing to beginners, so we have provided an example below using two NFL football teams:


American Odds

A listed odd with a + sign in front of it, such as the +120 in our example above, shows us how much money you would win on a $100 bet. 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.


Decimal Style Sports Betting Odds

Decimal style odds are used mostly in Europe, and are pretty easy to understand. To calculate the decimal style odds all you will need to do is simply multiply the amount you wish to wager by the decimal odds shown and you will get your payout. For example it may look something like this:
