What is the Bookmaker's Margin?

In reviews of bookmakers, there is always a mention of a concept called the "margin" (guaranteed profit). The margin can range from 3% to 25% in different bookmaking companies, depending on their business model strategy.

It's important to note that recreational players who bet for fun may not pay much attention to this aspect. For small and infrequent bets, the size of the bookmaker's margin is not significant. However, for regular and high-stakes players, for whom sports betting is a source of constant income, the margin's size becomes crucial Action Network: How Bookmakers Make Money. Let's delve into what the bookmaker's margin is and why it matters to players.

Understanding the Bookmaker's Margin

A bookmaker's business involves accepting bets from customers on various events https://rsabet.co.za/soccer/leagues/. In the event of a correctly predicted outcome, the player receives winnings, while an incorrect prediction means the stake goes to the bookmaker. The bookmaker's business plan ensures a guaranteed profit regardless of the event's outcome. This guaranteed profit is called the "margin."

The margin in sports betting refers to the bookmaker's guaranteed profit, which is embedded in the event's odds Wikipedia: Bookmaker.

Example of the Margin

For example, in a match between "Zenit" and "Spartak," the victory of the first team may seem much more likely than the victory of the second team. The majority of players Sporting News: Betting will bet on the home team, while some "Spartak" fans will place their bets on their team. A few players might have a hunch that the match will end in a draw.

To ensure a guaranteed profit, the bookmaker analyzes the event and assigns a specific odds to each possible outcome of the match.

Let's assume that about 50% of the bets are placed on "Zenit," 20% on "Spartak," and 30% on a draw. The bookmaker then converts these percentages into odds.

So, 50% would be converted to odds of 2.0 (100% divided by 50% equals 2.0), 30% to odds of 3.30 (100% divided by 30% equals 3.30), and 20% to odds of 5.0 (100% divided by 20% equals 5.0).

The size of the winnings is calculated by multiplying the bet amount by the odds. For instance, if you bet $10 on "Zenit" winning https://www.notebook.ai/users/611989, the winnings would be 10 * 2.0 = $20. Similarly, a successful bet on a draw would result in winnings of 10 * 3.30 = $33, and a successful bet on "Spartak" would result in winnings of 10 * 5.0 = $50. However, with this setup, the bookmaker would not earn anything and would distribute all the money collected to the players.

To guarantee a profit, the bookmaker lowers the odds. Therefore, the odds become less attractive to players and appear as follows: "Zenit" victory - 1.80, draw - 3.0, "Spartak" victory - 4.50. Each odds in this case is lowered by 10%. The bookmaker will pocket this 10% regardless of the match's outcome.

A simple way to determine the margin is to look at odds with equal chances (e.g., handicap or total), which usually range from 1.80-1.80 to 1.97-1.97.

Alternatively, you can use an odds comparison calculator ESPN Chalk: Sports Betting Homepage. To calculate the margin, you need to input the odds of the same event from different bookmakers.
