Definition
Decimal odds (European odds) show your total return per unit staked, including your original bet. Simply multiply your stake by the decimal to calculate total return. They're the easiest format for calculating payouts and comparing value across bets.
Example
Decimal odds of 2.50 mean a $100 bet returns $250 total ($150 profit + $100 stake). Odds of 1.50 return $150 ($50 profit). To calculate profit only: (decimal - 1) × stake.
