What is Dutching?
Backing several selections in an event so that no matter which wins, the returns are the same.
Dutching is a method used to divide a stake over several selections in an event so that the same amount is won regardless of which selection wins. This technique is helpful when you wish to back two or more outcomes and have a specific amount to stake. Before the rise of betting exchanges, dutching was sometimes used as an elaborate way to lay (bet against) a selection by backing everything else.
The dutching calculation is not always straightforward, with varying odds and betting exchange commissions to consider. Once you are comfortable with the concepts, try using the dutching calculator on this site to work out the precise amounts to stake on each selection.
Dutching Example
Imagine a horse race in which you have identified 2 runners with odds of 11/1 and 3/1 that you would like to back. With a total stake of £10 it might be tempting to split this into two £5 bets; however, should the 11/1 horse win, your returns would be much higher. The solution is to reduce the amount staked on the horse with higher odds and increase the stake proportionally on the other until the winnings are equal. The math behind this is as follows:
- First, work out the implied probabilities from the odds
- Implied Probability of an 11/1 runner = (1 / (11/1 + 1)) * 100 = 8.33%
- Implied Probability of an 3/1 runner = (1 / (3/1 + 1)) * 100 = 25%
- Work out the stakes
- Amount to stake on the 11/1 runner = (8.33 / (25 + 8.33)) * £10 = £2.50
- Amount to stake on the 3/1 runner = (25 / (25 + 8.33)) * £10 = £7.50
Now with the stake split evenly, the amount returned should any runner win is £30.
