Enter your total stake and the decimal odds for each selection. The calculator splits the stake so your return is the same whichever of those selections wins.
Enter a stake and at least two sets of decimal odds to see the split.
What is dutching?
Dutching means splitting one stake across several selections in the same event, sized so that your return is the same whichever of them wins.
It is the opposite of an accumulator. An acca needs every leg to come in; dutching backs alternatives, so only one of them has to win. You are trading a smaller potential return for a wider set of results that pay out.
How the maths works
Convert each price to its implied probability — 1 divided by the decimal odds — then give each selection that share of your total stake.
A selection at 2.50 implies 40% (1 ÷ 2.50). One at 5.00 implies 20%. Together that is 60% of a book, so of a £10 stake you would put two-thirds on the first and one-third on the second — and either result returns the same amount.
Why the book percentage matters
Add every implied probability together and a fair book totals 100%. Anything above that is the bookmaker's margin, and it is the reason backing every outcome in a market returns less than you staked.
That number is why price comparison matters here: a bigger price on any selection lowers the book percentage and improves the split. We measure the same figure on our Premier League odds page, where the typical single bookmaker's margin runs several percent higher than the best available prices taken together.
What dutching does not do
It does not remove risk. If none of your selections wins, the whole stake is lost — dutching changes how a stake is spread, not whether the bet can lose. It is a staking method, not a system for making money, and no staking method overcomes a bookmaker's margin over time.
Dutching calculator — common questions
What is dutching?
Dutching means splitting one stake across several selections in the same event, sized so that your return is the same whichever of them wins.
How do you calculate a dutching stake?
Convert each price to its implied probability (1 divided by the decimal odds), add them up, then give each selection that share of your total stake.
Does dutching guarantee a return?
No. You still lose the whole stake if none of your selections wins, and bookmaker margin means backing every outcome returns less than you staked.
What is the book percentage?
The implied probabilities added together. Above 100% is the bookmaker margin working against you; below 100% is unusual and normally means mixed bookmakers.
Is dutching the same as an accumulator?
No, the opposite. An accumulator needs every leg to win. Dutching spreads one stake across alternatives so only one of them needs to win.
