Back multiple selections in the same event with a single total budget. The calculator distributes your stake so the return is identical no matter which selection wins, and shows your profit percentage automatically.
Spread a total stake across multiple outcomes so that any winner returns the same profit. Enter the decimal odds for each selection.
Dutch betting is the technique of backing multiple selections in the same race or event using a stake distribution that guarantees the same profit regardless of which selection wins. It is named after the 1930s New York gangster Dutch Schultz, who reportedly used it on horse racing. The strategy is popular in horse racing, golf, and any market where one of several selections is likely to win.
For a total stake T and selections with decimal odds o₁, o₂, …, oₙ, the win return is T ÷ Σ(1/oᵢ). The stake on each selection is T ÷ (oᵢ × Σ(1/oᵢ)). The combined implied probability Σ(1/oᵢ) must be below 1.0 (100%) for a profit to be guaranteed.
Dutch betting and arbitrage are related but different. Arbitrage covers all possible outcomes of a single market across different bookmakers, guaranteeing profit regardless of any outcome including the ones you haven't backed. Dutch betting covers only a subset of outcomes, aiming for equal profit if one of your chosen selections wins — but you lose if none of them wins. Both strategies use inverse-probability stake distribution.
Your selections' combined implied probability must be below 100% to guarantee a profit. At 90% combined implied probability, your guaranteed profit is approximately 11% of your total stake. At 95% it's around 5%. Typical profitable Dutch books aim for combined probabilities of 70–85%.
Horse racing is the most popular market for Dutch betting, especially large fields where you can identify a group of 3–6 realistic winners. Golf Major winner markets, Formula 1 race winner markets, and football outright markets are also commonly dutched. In-play tennis is sometimes dutched on break of serve opportunities.
