How to Count Sports Betting Odds?

Each sportsbook offers many types of bets on different sporting events. The player is invited to choose a bet on the outcome of the matches, the total number of goals scored, the performance of individual players and many other events. The probability of each of these outcomes is expressed in odds.

What Is the Odds in Sports Betting

The odds is a numerical expression of the probability of an outcome of a sporting event in the bookmaker line. This probability is estimated as a percentage and can take a value from 0 to 100.

The odds is formed by dividing 100 by the probability of an event. It is initially estimated sports betting analysts based on the analysis of the upcoming sporting event.

How to calculate the odds for betting in an online sportsbook can be seen by the simplest example: tossing a coin. This event has only two outcomes, while heads and tails fall out with the same 50% probability. To calculate the odds, you need to divide 100 by 50. The oods for this event are 2.

But with a real sportsbook, this ratio cannot be, because its main task is to make a profit. To do this, a margin is put in the odds, which can be from 2 to 10%.

Let’s say the margin is 6%. It is evenly distributed over all outcomes, that is, in the example with the currency, it is 3%. So if we add a margin to the probability of an outcome, we get 53% and the odds 100/53 = 1.89.

The final value of the odds offered to players is formed by the amount of bets on each outcome. The sportsbook adjusts the oddds so that a profit can be made in any case.

In the example with a coin, you can imagine the situation where most players bet on the loss of an eagle. The online sportsbook will in this case lower the oods of this outcome and, accordingly, increase it to the contrary.

This algorithm is usually executed with a special program for each event. It forms odds based on three factors: the probability of an outcome, the margin and the current distribution of player bets.
