What are betting odds? Decimal and Fractions explained:
Decimal Odds
Decimal odds are the most widely used odds type and are offered by almost all bookmakers. Decimal odds show you how much money will be returned from a 1 unit stake. If a team is presented with odds @2,40 you will get 2,4 units back from a stake of 1 unit. Decimal odds are in most cases presented with an accuracy of two decimals for example @2,40 or @1,80
Example: Arsenal to win vs. Manchester Utd @1,80
stake: 100 units
return: 100 x @1,80 = 180 units
profit: 180 – 100 = 80 units
Fractional Odds
This way of presenting odds is common with UK bookmakers. The main difference between fractional and decimal odds is that while decimal show you how much money will be returned from a 1 unit stake the fractional odds tell you how much profit there is from a 1 unit stake.
Example: Arsenal to win vs. Manchester Utd @4/5
stake: 100 units
profit: 4/5 x 100 units = 80 units
return: (4/5 + 1) x 100 = 180 units
Conversion from fractional odds to decimal odds is easy: simply add + 1 to the fraction. With the example above odd @4/5 is equal to (4/5 + 1) = 0,8 + 1 =@1,80
