Decimal odds
Also known as: European odds
The odds format used in continental Europe and most of the world: a single number representing the total return (stake + profit) per unit staked. Odds of 2.50 mean a £10 bet returns £25 total (£15 profit). Decimal odds make probability calculation simple — implied probability is just 1 ÷ odds. Increasingly used in UK exchange markets and online sportsbooks.
