Odds Converter
Convert between decimal, fractional and American (moneyline) odds and implied probability instantly.
Decimal odds show your total return per £1 staked (stake included). Fractional odds show profit relative to stake. American odds show profit on a £100 stake (positive) or the stake needed to win £100 (negative). Implied probability is the break-even win rate the odds represent.
Frequently asked questions
Subtract 1 from the decimal odds and express the result as a fraction in its simplest form. For example, decimal odds of 2.50 become 1.50/1, which simplifies to 3/2.
