#### Bookmaker's margin

Every player should be able to calculate the margin of a bookmaker's office. After all, your winnings depend on it! Let's find out how to calculate the bookmaker's margin.

Beginner bettors when choosing a bookmaker usually pay attention to everything except the bookmaker's margin. What is a bookmaker's margin, how to calculate it and why you need to calculate it, we will examine in this article.

## What is the bookmaker's margin

Margin means "difference, advantage". Pari match bookmaker margin is the amount of commission, which bookmakers put in the odds. Bookmaker earns on margin at any outcome of a sporting event by charging a commission on the amount of bets. It is this, not lost bets, that ensures the bookmaker's business is profitable.

Margin distorts the net probability of an event, which is built into the odds. If we add up the odds of all possible outcomes of a match and don't take away the margin, the sum of probabilities will be more than 100%.

Let's imagine the situation. You are watching a tennis match between two debutants. No one knows the strength and experience of each, no other factors are taken into account. The probability of each winning in such a case is 50%. Like the probability of a perfect center-of-gravity coin toss of heads or tails, for example. Convert the odds to a factor using the formula: 1 / probability x 100 = 2.00. Or: 1 / 50 x 100 = 2.00.

There is no margin in this odds. Bettor #1 will bet $10 on the first athlete, bettor #2 will bet $10 on the second athlete. Whoever wins, the bookmaker gets nothing: he will simply hand over $10 from one bettor to the other bettor.

That's why the bookmaker includes a margin. He acts as an organizer in the dispute and wants to get his deserved commission. And the odds go down. If the odds are equal, they may be 1.95 to 1.95, or 1.90 to 1.90, or 1.85 to 1.85, or even lower. And in this case the bookmaker's office will get $10 from the loser and will pay less to the winner.

## What is the bookmaker's margin

Margin varies from bookmaker to bookmaker. Moreover, at the same bookmaker's office it differs depending on the sport, tournament, event and even the bet you are going to make.

It is customary to distinguish fundamental and low-margin bookmakers. The first put a high percentage margin. The average is about 5-7%. Low-margin ones work with a margin of 1.5-3%. But that doesn't mean that the second type of BK will suit you better than the first. And here's why.

Fundamental betting companies are focused on a wide audience. They offer a large selection of events with different betting variations on them. In return, the player will get a high margin on unpopular markets, statistics. In most fundamental betting houses odds on the top events are about equal to those of low-margin betting houses.

Low-margin betting houses not only have low margins but also offer limited markets for betting. Such offices attract professional players, playing on a difference of odds on the same event in different betting shops. For the rest such office will seem "fresh" because of the lack of a wide line, betting on statistics and good live betting.
