Bookmaker coefficient: the formula. Comparison of betting odds

It is known that sports give us the opportunity not only to cheer for your favorite athlete or team, but also decently earn on it. Bookmakers daily accept hundreds of bets and only a few of them become more or less profitable. So how do you get the most out of your bet? This will help the ability to use and calculate the bookmaker coefficient. What it means and how to calculate it you can learn from this article.

What does the bookmaker do?

Bookmaker's office is a commercial organization whose activity consists in accepting rates for sports and entertainment events. That is, the bookmaker office allows all wishing to make money on the correctly guessed outcome of the bet.

The activity of the bookmaker office resembles the conclusion of a kind of monetary dispute between the player and the organization. Two main outcomes - either won or lost. Therefore, before understanding the concept of "bookmaker coefficient", it is necessary to find out what the bookmakers specialize in. Their main areas are football, hockey, handball, biathlon, etc. That is, all sports events, especially international scale.

With the advent of the Internet, bookmakers went outside of small dark rooms and began to accept online bets. It has also become profitable for players, as comparison of bookmaker coefficients of different organizations can now be made without leaving home.

What is the bookmaker ratio?

To bet on the victory of your favorite team you need to understand what the probability of winning it. The bookmaker coefficient is a ratio that shows how likely an event will be, according to the bookmaker. Therefore, the amount of winnings is calculated by multiplying the amount of the bet by a coefficient.

When calculating the coefficient bookmakers consider the following factors:

• The result of the previous meeting of the competing teams;
• The place of a team or an athlete in the world ranking;
• Level of team preparation;
• The status and scope of the event;
• Place of event, etc.

And this coefficient can change before the start of a match or competition due to the announcement of new, previously unknown circumstances. For example, the player's injury, changing the place of the event, etc.

Types of betting odds

In view of the fact that bookmaking is popular all over the world, then the history of bookmaker coefficients is quite wide. But as practice shows, the most accurate are only three methods of calculation. The main types of betting odds:

• English;
• European;
• American.

And already based on its kind, the bookmaker coefficients are calculated. Each of them will be told in more detail.

English ratio

It is generally accepted that bookmakers are from England. Therefore, there is nothing strange that they have their own idea of how bookmaker coefficients are calculated. English coefficients are used outside the foggy Albion because of their convenience and simplicity of calculation.

The English bookmaker coefficient is recorded in fractional format, for example, 30/5. The first number indicates the actual amount of the winnings, and the second the amount of the bet. That is, putting 5 dollars to win your favorite team, you can win $ 30 with a successful outcome of the game. Also, the fractional coefficient can be transformed into a probability formula. It looks like this:

% Probabilities = (Denominator / (Numerator + Denominator)) * 100%.

With our coefficient, the probability percentage will be:

(5 / (30 + 5)) * 100% = 14.3%.

European coefficient

The European coefficient or decimal is the most popular among bookmakers. They are considered to be the simplest, therefore they have received such wide distribution. To date, the European bookmaker coefficient can be seen in bookmakers around the world, and in many of them it is the only one.

The European coefficient is written in the form of a decimal number, for example, 1.74. The winning amount is calculated by multiplying the rate by the coefficient. Let's say the bet was $ 10, which means that the gain at 1.74 is $ 17.4. Therefore, the net profit will be 7.4 dollars (17.4-10). In order to immediately calculate the amount of net profit, it is enough to subtract 1 from the bookmaker coefficient and multiply the resulting value by the size of the bet. You can also find the probability percentage using the bookmaker coefficient. The probability formula has the form:

% Probabilities = (1 / coefficient) * 100%.

In our case, the probability percentage is:

(1 / 1.74) * 100% = 57.5%.

American coefficient

Of the three main species, the American coefficient is the most difficult to perceive. Most often it can be found on the territory of the United States of America. Its main difference is to put the signs "+/-" before the numeric index. With the help of these signs, American bookmakers mark the favorite team. If the coefficient is "-", then the team has the status of the favorite.

To understand the intricate American system of calculation, it is necessary to disassemble an illustrative example. Suppose given:

1. The positive coefficient is +170 for a draw and +200 for a win.
2. Negative - - 130.

This means that when betting on a positive ratio, the player needs to put $ 100 to get $ 170 or $ 200 net profit.

When betting on a negative coefficient, the player needs to bet $ 130 to get a profit of $ 100.

The American betting odds, like English and European, can be converted into a probability formula.

Formula for a positive coefficient:

% Probabilities = 100% * ((- (negative coefficient)) / (- (negative coefficient) +100))

100% * (- (- 130) / - (- 130) +100) = 100% * (130/230) = 56.5%.

The formula for the negative coefficient:

% Probability = 100% * 100 / ((position coefficient) +100)

100% * 100/170 + 100 = 37%.

Comparison of betting odds

To date, there are a huge number of bookmakers, in which the coefficients can vary significantly. To extract the maximum revenue from the bet, the player can use the online services to compare the bookmaker odds. As a rule, they do not require a separate fee for the services provided. All you need to do to the user is to go through a simple registration process.

Advantages of using the services of comparison of bookmaker coefficients:

1. The ability to bet on the maximum ratio and, accordingly, to extract the maximum profit.
2. Saves time by not having to independently compare the coefficient lines.
3. A convenient and safe way to find forks.

It is best to choose a service that scans the largest number of bookmakers and has a high response rate to change the current coefficients.
