Understanding Odds Formats
🇺🇸 American Odds
The most common format in the US. Negative numbers (e.g., -110) show how much you need to bet to win $100. Positive numbers (e.g., +150) show how much you win on a $100 bet.
🔢 Decimal Odds
Popular in Europe and Australia. Simply multiply your stake by the decimal odds to get your total return. For example, $100 at 2.50 odds returns $250 ($150 profit + $100 stake).
🇬🇧 Fractional Odds
Traditional format used in the UK. The fraction shows profit relative to stake. For example, 3/1 means you win $3 for every $1 bet (plus your stake back).
