What dutching is
Dutching means backing several outcomes of one event, each with its own stake, sized so that any winner returns the same amount. Punters use it in racing to cover two or three runners they rate, and in sports markets to back a few players to score first, or a couple of teams in a futures market.
When dutching pays, and when it cannot
Dutching does not create value. It combines prices into one: backing three selections is the same as a single bet that one of the three wins, at the combined odds the calculator shows. It is worth doing only when that combined price is better than the real chance of one of them winning, so take each selection at the best price you can find.
The book tells you the rest. Add up the chances your prices imply: at 100% or more, a winner cannot return your total stake. That is what happens when you dutch every outcome at one bookmaker, because every market carries its margin. Every outcome at prices that add up to less than 100% is an arbitrage instead, and the arbitrage calculator splits that.
The formula
stakeᵢ = total × (1/Oᵢ) ÷ book
return = total ÷ book profit = return − total
Worked example
$100 across three runners at 4.00, 5.00 and 6.00. Those prices imply 25%, 20% and 16.67%, a book of 61.67%. Stake $40.54, $32.43 and $27.03: whichever runner wins returns $162.16, a $62.16 profit, the same as one bet at 1.62. If none of them wins, the $100 is lost. Rounded to the cent, the three returns differ by a few cents.

FAQ
How do you calculate dutching stakes?
Divide one by each selection’s decimal price and add the results: that is the book. Each stake is your total × (1 ÷ its price) ÷ the book. With $100 on 4.00, 5.00 and 6.00 the book is 0.6167, so the stakes are $40.54, $32.43 and $27.03, and any winner returns $162.16.
Is dutching profitable?
Only as profitable as the prices. Dutching turns several prices into one combined price, and it makes money over time only if that price is better than the real chance of one of your selections winning. It removes the risk of backing the wrong one of them, not the risk of all of them losing.
What is the difference between dutching and arbitrage?
Dutching backs some of the outcomes in a market, so you lose the lot if none of them wins. An arbitrage backs every outcome, across bookmakers, at prices that add up to less than 100%, so one of them has to win. The arbitrage calculator does that split for two outcomes.
What happens if a selection is scratched?
A scratched runner’s stake is normally refunded, and the stakes left no longer return the same amount. A late scratching can also bring a deduction off fixed-odds win bets on the runners still in the race. Check your bookmaker’s rules and recalculate with the selections that remain.
