Dutching Calculator
Enter your total stake and the odds for each selection. The calculator works out how much to put on each selection so you return the same profit whichever one wins.
What is Dutching?
Dutching is a strategy where you back multiple selections in the same race or event using calculated stakes, so that you return the same profit whichever of your backed selections wins. It is named after Al Capone's accountant Dutch Schultz, who reportedly used the method.
How Dutching Works
The key is proportional staking. You allocate more of your total stake to shorter-priced selections and less to longer-priced ones, in precise proportion to the implied probability of each. The result is an equal return regardless of which selection wins - provided at least one of them does.
Dutching works best when you have identified a race or market where you are confident one of two or three specific outcomes will occur, but you are not sure which. For example, in a football match you might want to back both team A and the draw while leaving out team B.
Limitations
Dutching only generates a profit if the combined implied probability of your backed selections is less than 100%. If the total exceeds 100%, you are backing too much of the market and guaranteed a loss. This is why dutching often works better in markets with low bookmaker margins - see our margin calculator to check margins before dutching.
For backing every outcome at different bookmakers to guarantee a profit, that is arbitrage - see our arbitrage calculator. For the theory behind value and probability, read the value betting guide.
