Understanding Odds Formats
Decimal Odds — The most common format for European and esports bookmakers. The number represents total return per unit staked. For example, odds of 2.50 mean a $10 bet returns $25 total ($15 profit + $10 stake). Higher decimal odds mean a less likely outcome with a bigger potential payout.
Fractional Odds — Traditional format used primarily by UK bookmakers. Displayed as a fraction like 5/2 or 3/1. The first number is the profit you win relative to the second number staked. So 5/2 means you win $5 profit for every $2 staked.
American Odds — Used mainly in the United States. Positive odds (+200) show how much profit you win on a $100 bet. Negative odds (-150) show how much you need to stake to win $100 profit. Positive = underdog, negative = favorite.
