How to calculate a bookmaker's margin? What is the bookmaker's margin? Legal bookmakers with the lowest margins

This allows the office to make a profit regardless of the distribution of bets. The higher the margin, the higher the profit of the bookmaker.

Let's take a closer look at what betting margin is and how to calculate it.

What is margin in sports betting?

Each player paid attention to the fact that events that in another situation would be equally probable, in the bookmaker's office have odds of 1.85-1.95.

Let's look at an example. A bookmaker offers to place a bet on a tennis match. A draw is impossible here, the opponents are approximately equal. Chances – 50*50. We convert the probability of victory for each of them into odds: 100% / 50% = 2.

The margin is set individually in each office. In some it does not exceed 2%, in others it reaches 10 or higher. It all depends on how much the bookmaker plans to earn, and how he feels about the fall in bets - most players prefer to play in bookmakers with a small margin.

How to calculate bookmaker margin

Finding out the margin that the bookmaker puts into the odds is very simple. To do this, it is enough to know the formula.

Margin = (100 / K1 + 100 / K2) – 100. This formula is suitable for two possible outcomes.

Margin = (100 / K1 + 100 / K2 + 100 / K3) – 100 – situation with three possible outcomes.

Eg, let's calculate the margin for a tennis match. Bets are divided into the victory of the first athlete and the victory of the second athlete. P1 = 2.30, P2 = 1.60. There is no draw in tennis.

Margin = (100 / 2.3) + (100 / 1.65) – 100 = 104.08 – 100 = 4.08 . This is the margin that the bookmaker has included in this odds.

We carry out a similar calculation for football match. There are three possible outcomes:

• Victory of the first team P1 with odds of 1.5
• Draw with odds 4.0
• Victory of the second team P2 with odds of 2.6

We calculate margin using the formula:

Margin = (100 / 2.5 + 100 / 4.0 + 100 / 2.6) – 100 = 103.46 – 100 = 3.46 – the amount of margin that the bookmaker puts into bets.

In some cases, it is not possible to determine the margin in this way - for example, if the match involves a 100% favorite, and the bookmaker sets double-digit odds for the underdog to win. In this case, the size of the coefficient is influenced not only by the chances of both teams to win and the margin, but also by the number of bets placed on the victory of the favorite and the underdog. The bookmaker can vary the odds to even out the statistics a little.

In most cases, the margin can be calculated and this data can be used in the future when choosing a bookmaker for a bet. The lower the margin, the higher the coefficient, and the more amount potential profit with the right bet. If you place bets rarely and little by little, this factor will not be important to you. However, if you plan to receive a stable income from betting, in the long term (1000 bets or more) even half a percent will result in a substantial amount.

All fans who bet their hard earned money at bookmakers are faced with a margin. We tell you what it is, how it can be calculated and why it is needed.

What is margin in a bookmaker?

Both the most experienced bookmaker regular and the green beginner are faced with, sometimes without even realizing it. This word came from French and translated means difference or advantage. This is essentially the bookmaker's commission. It is included in the coefficients.This term is used not only in bookmaking - in any business.

Based on the above, we can define margin as follows: it is the share of the accepted amount that the bookmaker earns on average, regardless of the outcome of the event.

To better understand the essence of margin, let's consider the situation. The office offers to bet on a tennis match. It meets equal opponents. A draw is impossible. So the chances are 50% to 50%. We convert the probability of victory of any of them into a coefficient like this: 100% / 50% = 2.

Perhaps, in an ideal world, the odds for both participants would be 2.00. But if people bet the same amount of money on each of them, the bookmaker will receive nothing. This situation is not beneficial for him.

What does a bookmaker do? That's right, it puts its margin into the odds. And we get 1.95 on both sides, and more often 1.91 or even lower.

What margin do bookmakers have?

Bookmakers are divided into two types:

• fundamental;
• low-margin.

The essence of the second is in the name. In bookmakers of this type, the most low margin. For example, the most famous among them claims a margin of 1.5-2.5%, depending on the type of sport. Fundamental bookmakers lay down 5% or more. They are also classic and recreational, that is, intended for relaxing while playing. These, for example, include Russian bookmakers and.

Other main differences between low-margin bookmakers– high highs and little choice bets in the pre-match, and also practically absent “live”. Such offices are suitable for professional players.

A narrow list forces players to bet on the main markets and helps the bookmaker balance the accepted money. At the same time, he gets the opportunity to accept much more fundamental office. For a low-margin company, it is very important to set and adjust ratios with surgical precision.

Fundamental bookmakers make most of their money from players' losses. Therefore, unexpected outcomes that go against expectations, or a classic 0:0 draw, are like manna from heaven for them.

How to calculate a bookmaker's margin?

Using simple fifth grade level math, we will now determine the bookmaker's margin using an example.

Here is the formula for a market with two outcomes to calculate:

Margin (in %) = (1/Odds 1 + 1/Odds 2 – 1) x 100

Let's consider the simplest option. Suppose that in a tennis match between equal opponents, we are offered to bet on each side with odds of 1.80. Let's calculate what margin is included in this line:

(1/1.80 + 1/1.80 – 1) x 100 = 0.111 x 100 = 11.1. Margin – 11.1%

Let's move on to slightly more complex layouts. For example, let’s calculate the margin on the Milan Derby, which will take place in mid-October. One well-known site offers us the following odds:

• Inter's victory – 2.10;
• Milan's victory – 3.25;
• They offer to bet on a draw for 3.38.

The formula for the three-outcome is no different from the previous one. Only instead of the probabilities of two outcomes, we now sum up the chances of three:

(1/2.1 + 1/3.25 + 1/3.38 – 1) x 100 = 0.0797 x 100 = 8 (we rounded up a bit)

That is, the bookmaker’s margin is 8%.

Why should you be able to calculate the bookmaker's margin?

Choosing a bookmaker is like going to the market, where you are looking for meat at the lowest price with quality that satisfies you. The price here is the bookmaker's margin. The lower it is, the higher the odds - and the more you will win if you make the right bet. Quality – selection of events and bets. The narrow painting cannot be called poor quality, but still most players are looking for fattier meat on the market.

You shouldn't chase low margins. You'll just get bored. It is important to choose the best ratio of odds, selection of events and outcomes for sports betting. Only then will you enjoy the game.

Bookmaker's margin (BC) ) is a commission that is included in a certain outcome of an event. The higher the margin, the lower the potential profit that a bookmaker's player can receive. The bookmaker's margin is calculated automatically using simple mathematical calculations.

IMPORTANT! Before betting, make sure the odds are decent. There are often situations when the bookmaker is afraid of incurring losses and therefore sets odds that are not profitable for the players (see figure below). Some people don't notice this and bet no matter what.

Who should know about bookmaker margins?

People who bet small amounts are unlikely to be interested this question. Since it is quite difficult to notice the bookmaker’s margin on amounts of 150-200 rubles. In cases, for example, when bets are made in the amount of 100,000 rubles. or more, even 1% of the bookmaker’s margin, can be fundamental for players. For different events, the margin laid down by the bookmaker's office can fluctuate greatly, depending on the confidence of the bookmaker's analysts in a particular event. No matter how funny it may sound, there are situations in which one bookmaker can offer 40% less than another bookmaker

Bookmaker margin example

Let's look at an example of how the bookmaker's margin for an event is calculated. Let's imagine that a tennis match between Sharapova and Mugursa is planned for tomorrow. In the bookmaker's line we see that the odds for Sharapova's victory are 1.8, and for Muguruza's victory 2. The bet size for all bettors will be the same - 1000 rubles. Let's imagine that 100 people bet on Sharapova to win and 100 people on Muguruza to win. Tomorrow has arrived and we are happy to learn that Mrs. Sharapova has won. This means that 100 people remained in the black, net profit from the winnings amounted to 80,000 rubles.

(100(number of people)*1000(bet amount)*1.8(odds)-100000(initial bet amount)

However, one hundred people who bet on Muguruza lost and the money remained with the Bookmaker. total amount, which remained with the bookmaker after Muguruza’s loss of 100,000 rubles (100*1000). Now the bookmaker gives 80,000 rubles to the winners and keeps 20,000 rubles. These 20,000 rubles will be the bookmaker’s margin. It turns out that bookmakers are only intermediaries between players. In principle, this is logical, because they only offer BET, and the choice is up to the players.

What is the bookmaker's margin?

Naturally, any bookmaker has its own margin. The larger the bookmaker, the larger its client list, and therefore the margin will be smaller. Large bookmakers that have earned a good reputation for themselves are ready to give players high odds, which include a minimum margin of 5-7%. In small offices this percentage is much higher and can range from 15 to 20 percent; naturally, this can negatively affect the attraction of large clients.

Bookmaker's margin: bookmaker's greed indicator

What is bookmaker margin and how to calculate it

Bookmaker's margin

Obviously, all players who have at least once risked their money could not help but hear about such a concept as “bookmaker’s margin.” However, very few people understand the essence of this indicator and what impact it has on the possibility of leaving a bookmaker out of business.

In this material we will talk about what this margin is, on what principle it is calculated, and also what it can affect. Margin bookmaker is called fixed percentage, subtracted from the amount won by the bettor into the bookmaker’s “pocket”.

For example, the player found in game line reliable promising event with odds of 1.91. At first glance, everything here is simply calculated. We bet the amount of 100 dollars and if the bet passes, we win 191 dollars (100 x 1.91). That is, the net profit amounted to $91 minus the bet itself. At first glance, not a penny “wasted” anywhere. But here’s the thing: the margin in the bookmakers is built into each odds in advance! How to see the margin, how to calculate it as a percentage? More on this later.

In order to better understand the essence, we will use the theory of probability. To do this, we will calculate a bet on two outcomes on even and odd bookmaker bets in which there is a margin.

In fact, it is not possible to give a correct forecast for the outcome of such a bet. Perhaps such a bet can be compared to flipping a coin up and guessing “heads” or “tails”. Both selected events should initially be called probable in equally: These are a typical “50/50” case. A fair, visible odds for such an event are not difficult to understand and calculate, and this is a “two”, because a loss means a loss of money, a win means doubling the bet. But here’s the thing: if you bet $100 on such an event at a bookmaker’s office, you will only get $95 in winnings (maybe a little more or less, it doesn’t matter for now).

This means that the player risks losing a hundred dollars, but hopes to win only 95. We will omit moral aspects, such as fairness, but these “underpaid” 5 dollars are the very margin of the bookmaker’s office.

If there are more than two outcomes, then we add to the formula the coefficients of the third and subsequent outcome, for example, M = (100/K1 + 100/K2 + 100/K3) – 100.

Well, in the end, let’s consolidate with examples.

Example.
Italy. Serie A. Milan - Inter.
P1 - 1.80, P2 - 2.05. We calculate the bookmaker's margin.
M = (100/1.8 + 100/2.05) -100 = 4.3%.

We see that for every hundred dollars won on this particular bet, bookmakers on average will take home 4.3 dollars. And this is regardless of what the outcome of the match will be.

Example.
Spain. Example division. Real Madrid - Osasuna.
P1 - 1.19, X - 7.73, P2 - 19.81. We calculate the bookmaker's margin.
M = (100/1.19+100/7.73 +100/19.81) - 100 = 2.02%.
IN last example By the way, the margin is very small, which means that the bookmaker probably has quite acceptable odds for players.

Why is it better to choose bookmakers with low margins?

We recommend choosing an office with a low margin. With a high degree of probability, such a company will be more loyal to players, making a profit thanks to the huge turnover. By playing at high-margin bookmakers, you reduce your chances of making a profit in the long run. After all, over a long distance, say 500 bets, even 1 percent will ultimately make a significant difference.

Which bookmakers have the lowest margins?

Very attractive margins at the bookmaker Pinnacle- about 2%. On top of that, you won't encounter any problems there.

Relatively low margins at bookmakers Marathon, 1xbet, Betcity- 3-5%, but there you may encounter limit cuts. Approximately the same margin and similar problems await you in Fonbete, PariMatch, etc.

Particularly high margins were observed in Leone, Winline, League of Betting, Balbet and similar Russian offices- from 6.5%.

Please note that the margin tends to change, so follow the news of bookmakers and periodically check the margin value yourself.

Often, when reading the description of a particular bookmaker, you can come across the item “margin”. The size of this very margin at different bookmakers can vary from 5 to 20 percent. It all depends on how popular the bookmaker is and what business strategy it pursues.

What is bookmaker's margin?

It should be immediately noted that small players who play for fun should not pay special attention to this point. The fact is that for small bets the size of the bookmaker’s margin is insignificant. But for those who play big and who have chosen sports betting as a source of stable income, the size of the margin can play a big role. Let's figure out what the bookmaker's margin is and why it is important for players.

Almost any bookmaker is legal entity, whose business is to accept bets on various events from its clients. If the player correctly predicts the outcome, then he is entitled to win. If the outcome is not guessed, then the amount of his bet goes to the bookmaker. The bookmaker's business plan involves regular tracking public opinion regarding various events, and for this very reason, no matter what the outcome of a particular match will be, the bookmaker must always have a guaranteed profit. And the amount of this profit is called margin.

After completing the registration procedure at the bookmaker’s office, the player gets access to an extensive list of sporting events, the so-called “line”. The player's goal is very simple. It consists of choosing an event you like and correctly predicting its outcome. And if the outcome is predicted correctly, the player’s account is replenished with the amount of winnings. But, as you know, the probability of the outcome of an event is not the same.

Margin calculation example

For example, in the English Premier League match Chelsea - Liverpool, the victory of the first club has a much higher high probability, than the second. And, of course, most players will bet on the home team winning. And some loyal Liverpool fans will bet on their team to win. Another part of the players will decide that this meeting will end in a draw, and will also make a corresponding bet.

To ensure a guaranteed profit, the bookmaker studies the event, and each outcome is assigned a certain coefficient, according to which the winnings are calculated.

For example, approximately half of all players will bet on Chelsea. 20 percent will think Liverpool will win. And 30 percent believe that there is no favorite in the match and will bet on a draw. What does a bookmaker do? Converts these numbers into coefficients.

Therefore, 50 percent understandably becomes a factor of 2.00 (100 percent/50 percent = 2.00), 30 percent becomes 3.3 (100 percent/30 percent = 3.3), and 20 percent becomes 5.00 (100 percent/20 percent). Bookmakers calculate the winning amount as follows: the bet size is multiplied by the odds size. So, if you place a bet of 10 rubles on the home team’s victory, then if you manage to guess correctly, the size of your winnings will be 10X2.00 = 20 rubles. And accordingly, if you bet on a draw, and the match ended, then 10X3.3 = 33 rubles, and if the bet on Liverpool’s victory turned out to be correct, then 10X5.00 = 50 rubles. However, in this case, the bookmaker will distribute all the proceeds to the players.

To ensure their profits, bookmakers reduce odds by 5-20 percent. Consequently, the odds now become less attractive for players and look as follows: Chelsea win - 1.8, draw - 3.00, Liverpool win - 4.5. It turns out that in this case all coefficients are reduced by 10 percent. And this 10 percent will go to the bookmaker’s account, regardless of the outcome of the match.

An easy way to determine lower margins at a bookmaker is to look at the even odds events, which typically range from 1.8/1.8 – 1.96/1.96

Margin size at bookmakers

Every bookmaker has its own margin. The larger the office, the more extensive it has a list of clients, and, consequently, the smaller the margin that the office will provide good profit. Serious, already earned a reputation in international market offices with a large cash turnover are content with 5 percent. In smaller offices, the margin percentage varies from 10 to 20 percent, and this affects the attractiveness of the odds.

To date, the lowest margin is in . From this we can conclude that here the coefficients are the highest.
