See live edgesDecimal odds (European odds) show your total return for every $1 wagered, including your stake. If odds are 2.50, a $100 bet returns $250 total ($150 profit + $100 stake). Decimal odds are the simplest format for calculating payouts and are standard in Europe, Australia, and Canada.
American odds (moneyline) use positive and negative numbers. Positive odds (+150) show profit on a $100 bet. Negative odds (-150) show how much you need to bet to profit $100. American odds are standard in the United States.
Fractional odds (British odds) show potential profit relative to stake. Odds of 3/2 mean you profit $3 for every $2 wagered. Fractional odds are traditional in the UK and Ireland, especially for horse racing.
Implied probability converts odds into the percentage chance they represent. This helps you assess whether odds offer value compared to your own probability estimates. If you believe an outcome has a 50% chance but odds imply only 40%, that's a potential edge.
