How it works
Dutching is a technique where you back multiple selections in the same event — at one or several bookmakers — and distribute your stake so that the payout is identical whichever selection wins. Unlike a surebet, dutching does not guarantee a profit: your return depends on the available odds and the bookmaker's margin. But it does let you cover multiple outcomes without having to pick just one.
The formula is straightforward: each selection's stake is proportional to its implied probability (1/odds) divided by the sum of implied probabilities across all selected outcomes. The result is a perfectly balanced payout. The higher the odds and the lower the bookmaker's margin, the more favourable your return on stake.
Dutching is particularly useful in horse racing with several runners, three-way markets, or whenever you have conviction on multiple selections but want to control your exposure. Pro tip: if the sum of implied probabilities for your selections exceeds 100 %, the bookmaker has the mathematical edge; if it falls below 100 %, you've spotted a surebet opportunity. This calculator automatically displays the bookmaker margin so you can assess the quality of your combination at a glance.
