Decimal Odds
Decimal Odds
Definition
Decimal odds are a popular format for displaying betting odds, especially in Europe, Canada, Australia, and Asia. Unlike fractional or American odds, decimal odds represent the total payout (stake + profit) for every 1 unit wagered.
Formula
To calculate the potential return, simply use:
Return = Stake × Decimal Odds
To find the profit only, subtract your stake:
Profit = (Stake × Decimal Odds) – Stake
Example
-
Decimal odds: 2.50
-
Stake: €100
-
Return = €100 × 2.50 = €250
-
Profit = €250 – €100 = €150
Interpretation
| Decimal Odds | Implied Probability | Description |
|---|---|---|
| 1.50 | 66.7% | Strong favorite |
| 2.00 | 50.0% | Even odds (coin flip) |
| 3.00 | 33.3% | Moderate underdog |
| 5.00+ | 20% or less | Major outsider |
To calculate implied probability, use:
Implied Probability (%) = (1 ÷ Decimal Odds) × 100
Advantages of Decimal Odds

Easier to understand than fractional odds

Clear display of total return (not just profit)
