What is dutching?
Dutching means backing multiple selections in the same event with calculated stakes so that you win the same profit no matter which one wins. Instead of picking one winner, you spread your money across several possibilities. The key: dutching only works if the combined implied probability of your selections is under 100%.
When is dutching profitable?
Dutching is profitable when the bookmaker's odds for your chosen selections imply a combined probability of less than 100%. This can happen when odds are generous across multiple outcomes, or when you're using odds from different bookmakers. If the combined probability exceeds 100%, dutching guarantees a loss — the calculator will warn you.
Dutching vs accumulator
An accumulator needs every selection to win. Dutching needs just one — but they must all be in the same event. Dutching trades the high potential returns of an acca for certainty: you know exactly what you'll win before the event starts. It's a fundamentally different approach — risk reduction rather than return multiplication.
How the dutching calculator works
The dutching formula
For each selection, the individual stake is calculated as: total stake × (1 ÷ decimal odds of this selection) ÷ sum of (1 ÷ decimal odds for all selections). This ensures that the returns are identical no matter which selection wins.
Understanding implied probability
The combined implied probability is the sum of (1 ÷ decimal odds) for all selections, expressed as a percentage. If this total is under 100%, there's value in the market — the odds are generous enough to guarantee a profit. If it's over 100%, the bookmaker's margin makes dutching unprofitable.
Practical tips
Dutching opportunities are most common in markets with many runners (horse racing, golf outrights) or when comparing odds across multiple bookmakers. The more selections you include, the lower your profit per selection — but the more outcomes you cover. Start with 2-3 selections and check whether the combined probability is under 100%.
