Understanding Odds Formats
American Odds
Most common in the US. Positive numbers (+110) show profit on $100 bet. Negative numbers (-110) show amount needed to bet to win $100.
Decimal Odds
Popular in Europe and Australia. Shows total return for every $1 bet. For example, 2.10 means you get $2.10 back for every $1 bet (including your stake).
Fractional Odds
Traditional UK format. Shows profit relative to stake. 11/10 means you win $11 for every $10 bet.
Implied Probability
The percentage chance of an outcome according to the odds. Higher probability means lower odds and vice versa.
