What are fractional odds in betting?

Fractional odds, also known as British odds, are one of the three common formats used to represent betting odds. They are presented as a fraction, such as 2/1, 5/2, or 10/1.

Here’s how to interpret fractional odds:

  • Numerator: The numerator (the first number) represents how much you will win from a bet of the size of the denominator (the second number). For example, if the odds are 5/1, for every unit you bet, you will win 5 units in profit if your bet is successful.
  • Denominator: The denominator (the second number) represents the amount you need to bet to win the amount represented by the numerator. Using the previous example of 5/1, if you bet £1, you would win £5 in profit plus your original £1 stake back if your bet wins.

To calculate your total potential payout with fractional odds, you can use the following formula:

Total Payout=(Numerator/Denominator+1)×Stake

For example, if you bet £10 on odds of 5/1:

Total Payout=(5/1+1)×£10=£60

This includes your original £10 stake and £50 in profit.

Fractional odds are commonly used in the UK, and they indicate the profit you stand to make relative to your stake. If the odds are a fraction greater than 1 (e.g., 5/1), you will make a profit for every unit staked if your bet is successful. If the odds are less than 1 (e.g., 1/5), you will make less profit than the amount staked, and these odds indicate a favorite in the context of betting.
