Understanding Odds Formats

Fraction

Fractional odds, used primarily in the UK and Ireland, quote the potential profit relative to the stake. For example, 3/1 means you win £3 for every £1 bet, with a total return of £4 (your £1 stake plus £3 profit).

Decimal

Decimal odds, popular in Europe and Australia, quote the total return including your stake. For example, decimal odds of 4.0 mean a £1 bet returns £4 total (your £1 stake plus £3 profit).

American (Moneyline)

American odds, also known as Moneyline, use positive numbers for underdogs and negative numbers for favorites. Positive odds show how much you win on a $100 bet (e.g., +300 means win $300 on $100). Negative odds show how much you need to bet to win $100 (e.g., -200 means bet $200 to win $100).

Implied Probability

Implied probability shows the likelihood of an outcome based on the odds, expressed as a percentage. It's calculated as 1 divided by the decimal odds. For example, decimal odds of 4.0 imply a 25% chance (1/4 = 0.25 = 25%).
