Dutching Calculator
Split a stake across several horses for equal profit whichever wins.
Stakes are proportional to implied probability, so every selection returns the same amount. Take each horse's best available price — they don't all have to be with one bookmaker.
How dutching works
Dutching splits your stake across several horses in one race, weighted by implied probability (1 ÷ decimal odds), so that whichever of them wins, the return is identical. It turns "the winner is one of these three" into a single, well-defined bet with a synthetic combined price.
It doesn't create value by itself: the dutched bet is only as good as the combined true chance of your group against its combined implied probability. When and why that's worth doing — and when it's just paying several lots of bookmaker margin for indecision — is covered in our full dutching guide.
One free improvement: take each selection's best price across bookmakers rather than dutching everything at one firm. The odds comparison shows where each best price lives, and across three or four selections the difference routinely turns a marginal dutch into a value one.
FAQ
Total stake or target profit — which mode?
Total stake answers "I want £30 on this race". Target profit answers "I want to win £50 whichever of these wins" and tells you the outlay needed.
Why do shorter prices get bigger stakes?
Because they're more likely to be the one that wins — equal returns require stakes proportional to probability.
What if my combined implied chance is over 100%?
Then no stake split can guarantee a profit — you'd be dutching the whole market at bookmaker prices, which is just paying the overround.
What happens if one of my dutched horses is a non-runner?
That leg voids (or takes a Rule 4 if others withdraw) and the equal-profit balance breaks — recalculate with the remaining prices.
