Dutching Calculator

Dutching is staking different amounts on multiple selections in the same event so that if any of them wins, the return is identical. It spreads risk across outcomes without relying on a single pick.

Dutching only guarantees a profit when the combined implied probability of your selections is below 100% — i.e. you have found an under-round market. In overround markets, you will return less than your stake.

Dutching works well when you believe the winner is likely from a shortlist of 2–4 outcomes but cannot identify the single winner confidently. It reduces variance at the cost of a lower individual return.

Each selection's stake equals your total stake divided by the sum of all inverse odds, multiplied by that selection's inverse odds. This ensures each selection returns the same amount if it wins.

Yes — dutching works across any number of selections. Adding more selections reduces each individual stake but also increases total outlay, so the profit margin tightens with each additional runner.
