How Odds Formats Work

American odds show how much you win on a $100 bet (positive) or how much you must bet to win $100 (negative). Decimal odds represent your total return per $1 wagered. Fractional odds, popular in UK horse racing, show profit relative to stake. Implied probability converts any odds into a win percentage, which is essential for finding value bets.
