Understanding Odds Formats
Decimal (European) Odds
Decimal odds represent the total return you'll receive for a winning bet, including your stake. For example, odds of 2.50 mean you'll receive Ā£2.50 for every Ā£1 staked (Ā£1.50 profit plus your Ā£1 stake back).
This format is widely used in Europe, Australia, and Canada, and is the standard format for online betting exchanges.
Total Return = Stake Ć Decimal OddsProfit = Stake Ć (Decimal Odds - 1)
Examples
With a Ā£10 stake at odds of 2.00:
Total Return = Ā£10 Ć 2.00 = Ā£20
Profit = Ā£10 Ć (2.00 - 1) = Ā£10
With a Ā£10 stake at odds of 1.50:
Total Return = Ā£10 Ć 1.50 = Ā£15
Profit = Ā£10 Ć (1.50 - 1) = Ā£5
With a Ā£10 stake at odds of 3.75:
Total Return = Ā£10 Ć 3.75 = Ā£37.50
Profit = Ā£10 Ć (3.75 - 1) = Ā£27.50
