Dutching Calculator
Split one total stake across multiple selections for equal profit.
Dutching lets you back multiple outcomes in the same market and aim for roughly the same profit whichever selection wins. Traders often use it in horse racing, correct-score and other markets where more than one runner looks overpriced and they want to spread their risk.
How the calculation works
Core formula: Stakeᵢ = Total Stake × (1 / Oddsᵢ) ÷ Σ(1 / Odds)
Worked example: Total stake £100 across two selections at 3.0 and 4.5.
| Selection | Odds | Stake | Profit if wins |
|---|---|---|---|
| A | 3.0 | £60.00 | £80.00 |
| B | 4.5 | £40.00 | £80.00 |
- Inverse odds: 1/3.0 = 0.333, 1/4.5 = 0.222 (sum = 0.555).
- Stakes: £100 × 0.333/0.555 = £60.00 and £100 × 0.222/0.555 = £40.00.
