Odds can be displayed in two ways: Fractions or Decimals

You will probably be most familiar with odds as fractions (e.g. 3/1). However, you can choose to display them as decimals (e.g. 4.00) if you wish.

How to Change Odds Format

Below is a table highlighting the difference between the two:

Fractions

Whenever you see two numbers separated by a slash, i.e. 10/1, this is a fractional betting odd.

Fractional odds allow you to calculate how much money you will win on your bet in comparison to you stake. The number on the left(e.g. 10) is how much you will win. The number on the right is how much you need to stake.

for every £1/1EUR you bet, you will win £9/9EUR. This can also be calculated as 1 / (9 + 1) = 0.10 - There is a 10% chance that the event will happen.

for every £1/1EUR you bet, you will win £1/1EUR. This can also be calculated as 1 / (1 + 1) = 0.50 - There is a 50% chance that the event will happen.

for every £4/4EUR you bet, you will win £1/1EUR. This can also be calculated as 4 / (4 + 1) = 0.80 - There is a 80% chance that the event will happen.

Decimals

Whenever you see odds displayed in numeric form i.e. 9.00, this is a decimal betting odd.

Decimal odds allow you to calculate how much money you will be returned should your bet win. Simply multiply your stake by the decimal number shown and that is how much you will receive - including your stake. The decimal odds are displayed up to 2 decimal places, but the return will be paid out by calculating at the actual odds, to the nearest £0.01/0.01EUR. For example, if your bet is placed at odds of 4.3333333 (this is 10/3 in fractional), a £10/10EUR bet would return £43.33/43.33EUR if it wins, but your odds would show as 4.33.

 for every £1/1EUR you bet, you will win £8/8EUR. You will also receive your £1/1EUR stake back so your total return is £9/9EUR.

 for every £1/1EUR you bet, you will win £1/1EUR. You will also receive your £1/1EUR stake back so your total return is £2/2EUR.

 for every £4/4EUR you bet, you will win £1/1EUR. You will also receive your £4/4EUR stake back so your total return is £5/5EUR.
