How do betting odds work?

Different countries follow different forms of betting odds.

There are three main types of betting odds –

  1. Fractional odds – These are represented as fractional numbers like 10/1 or 10-1. Here, 10/1 fractional odds for an event means that if you win the bet, you will make a profit of $10 for every $1 bet. It means your net winning amount will be $11. The fractional odds show your profit amount only and not the total return.

Formula: Net Return = [Stake x fractional odds] + Stake

You can also calculate the percentage of your chances to win. If X/Y is the fractional odds provided by the bookmaker, then Y/(X+Y) is multiplied by 100 to get the winning probability. In the above example [1/(10+1)] x 100 is equal to 9%, which means that there is 9% chance that you will win the bet.

  1. Decimal odds – Decimal odds represent the amount you can win for every $1 bet. Unlike fractional odds, decimal odds are your total return including your profit and bet amount. The decimal odds of 5.00 for an event mean that you can earn a net pay-out of $5 for every $1 bet.

Formula: Net Return = Stake x decimal odds

  1. American or Moneyline odds – They are quoted as positive or negative values like +100, -400 and so on. The positive American odds show the winning amount for every $100 bet whereas negative American odds provide the required bet amount to win $100.
