Decimal odds and Implied Probability Explained

Here are the basics of Decimal odds and implied probabilities.

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.

Implied Probability

While sportsbooks don't typically express their odds in implied probabilities, all common odds formats can be converted to an implied probability. An implied probability is the percentage of times you'd need to win a bet (if you could bet it an infinite number of times) for that bet to breakeven.

For example, if your odds convert to an implied probability of 60%, your bet theoretically needs to win 60% of the time to breakeven. If it wins more than 60%, it'd be a profitable bet.

Keep in mind that sportsbooks add vig ("juice", "house edge", "tax", "fees", etc.) to their odds, meaning the implied probabilities of all outcomes for a scenario will have implied probabilities totaling greater than 100%.
