Convert between decimal, fractional, American (moneyline) and implied probability odds instantly.
Decimal odds are used in Europe and Australia. They represent your total return per €1 staked, including your stake. Decimal 2.50 means you get back €2.50 for every €1 bet — €1.50 profit.
Fractional odds are traditional UK format. 3/2 means you win €3 for every €2 staked. The left number is profit, the right number is stake.
American odds use + and − signs. +150 means a €100 bet wins €150 profit. −200 means you must bet €200 to win €100 profit.
Implied probability is what the odds suggest the true chance of winning is. Always compare this to your own assessment — if you think the chance is higher than implied, there's value in the bet.
