Common Odds Formats

• Decimal Odds: Popular in Europe and Australia, decimal odds show the total return for every unit staked. To calculate potential payout, multiply your stake by the decimal value.
• Fractional Odds: Traditional in the UK, these display the profit relative to the stake. For example, odds of 4/1 mean you win 4 units of profit for every 1 unit staked.
• American Odds: Also known as moneyline odds, these show either the amount you must wager to win $100 (for favorites, indicated by a minus sign) or the profit you receive from a $100 bet (for underdogs, indicated by a plus sign).

Understanding how these formats convert into one another is key. Regardless of which format you use, the underlying math remains the same, representing the probability of the match outcome. Having a firm grasp of these figures makes value calculation much easier.
