Fractional odds and Decimal odds Explained

Here are the basics of Fractional odds and Decimal odds.

Fractional Odds

Most popular in the United Kingdom and Ireland, fractional odds are expressed as a fraction where the denominator is the amount bet, and the numerator is your potential winnings. For example, if you win a bet placed at 1/3 odds, you'll profit $1 for every $3 bet.

Fraction odds are also commonly used in the United States for horse racing.

  • Fractional odds greater than 1 are underdogs, with larger fractions having a lower implied probability. 11/10 has an implied probability of 47.62% and 3/1 is 25%.
  • Fractional odds less than 1 are favorites, with smaller fractions having a higher implied probability. 10/11 is an implied probability of 52.38% and 1/3 is 75%.
  • 1/1 has an implied probability of exactly 50%.

Decimal Odds

Decimal odds are commonly used in continental Europe, Canada, and Australia. Decimal odds are a number greater than 1.

You can calculate your total payout by multiplying your bet size by the decimal odds. For example, a $10 bet at 2.5 decimal odds would payout $25. You can then subtract your bet from this total payout to find your potential profit ($25 - $10 = $15).

  • Decimal odds greater than 2 are underdogs, with larger decimal odds being less likely to win. 2.1 converts to a 47.62% implied probability, while 4.0 converts to 25%.
  • Decimal odds less than 2 are favorites. The lower the value, the bigger the favorite. 1.923 has an implied probability of 52%, while 1.25 is 80%.
  • Decimal odds of exactly 2 have a 50% implied probability.
