Online Margin Calculator for Sport Betting

Bookmakers’ odds include a margin — the difference between the real value and its market value.

The higher the margin, the harder it is for bettors to make a profit in the long run.

So, don’t ignore the bookmaker’s margin calculator when wagering — it could reduce your profits over time.

Reminder for bettors about bookmakers’ margin levels

How to Calculate Bookmaker’s Margin

Ever wondered why the odds for a 50-50 chance in a bet are never exactly 2.0, but instead range from 1.90 to 1.96? Well, that’s the bookmaker’s “margin”, which guarantees their profit no matter the match outcome.

Bookies rarely reveal the exact percentage of their margin; they simply bake it into the odds. That’s why savvy bettors look for bookmakers with lower commissions. To calculate the margin, you can use this formula:

Margin=(100/odds1)+(100/odds2)+(100/odds3)-100,

Where odds(n) are the bookmaker’s odds for different outcomes.

For example, if a football match at a bookmaker has odds of 2.25 for Home Win (1), 3.30 for Draw (X), and 3.0 for Away Win (2), then the margin would be:

Margin=(100/2.25)+(100/3.30)+(100/3.0)-100=8%

This means that regardless of the match result, the bookmaker would make a fixed 8% profit from the total bets placed on the match.

How a Bookmaker’s Margin Impacts a Bettor’s Success

Simply put, let’s say two players are betting on even odds. Player 1 goes with a bookie that charges a 2.5% commission, while Player 2 chooses one with a 6% commission. Now, every time Player 2 wins a bet, he loses 3.5% of his profit, whereas Player 1 opted for a lower margin bookie to maximize his gain. Over 1000 bets, these potential losses can add up significantly.

NOTE: Betting with a low margin not only increases the efficiency of bets, but also boosts overall profitability.

Why It’s Worth Registering with Multiple Bookmakers

Thanks to the highly competitive nature of the betting industry, bookmakers have to grab bettors’ attention not only with flashy promotions, but also with their odds. That’s why it’s smart to keep an eye on the lines of multiple bookmakers to find the best odds for your bets.

For instance, Asian bookmakers often offer low commission rates built into their football odds, while European brands may have higher odds for horse and dog racing. Russian bookmakers, on the other hand, may offer low margins for the Russian Premier League.

The margin policy can significantly impact a bettor’s profitability. That’s why calculators have been developed to help bettors save time and effort in manually calculating margins.
