What is Dutching?
Dutching is a strategy of backing multiple selections in the same event, with stakes calculated to produce the same profit regardless of which selection wins. It is named after Dutch Schultz, a 1930s New York gangster who allegedly used the technique at racetracks.
How It Works
The calculator divides your total stake proportionally based on the odds of each selection. Lower-odds selections receive a larger share of the stake, higher-odds selections receive less. The result is an equal profit from any winner.
The Formula
For each selection: Individual Stake = Total Stake × (1/Odds) / Sum of (1/Odds for all selections)
Example
You want to Dutch 3 horses in a race with a $100 total stake:
- Horse A: 3.00 → Stake = $100 × (1/3) / (1/3 + 1/5 + 1/8) = $43.48
- Horse B: 5.00 → Stake = $26.09
- Horse C: 8.00 → Stake = $16.30
Profit if any of the 3 wins = approximately $30.43
When Dutching Works
Dutching is profitable when the combined implied probability of your selections is less than 100%. If the total overround of your selected outcomes is under 100%, you have value regardless of which one wins.
Dutching vs Each-Way
In horse racing, Dutching multiple runners to win can sometimes offer better value than an each-way bet on a single selection, especially when the each-way terms are unfavourable (1/5 odds vs 1/4).
