Backing more than one selection in the same event, with the stakes split so that whichever of them wins returns the same amount. It is named after Arthur 'Dutch' Flegenheimer, a 1930s New York bookmaker credited with it.

How do you calculate dutching stakes?

Stake on selection i = total x (1/oddsᵢ) / sum of (1/odds) over your selections. Every selection then returns total / sum.

What is the difference between dutching and a surebet?

A surebet is dutching across every possible outcome, at prices whose implied probabilities add up to less than 1, so any result returns more than the stake. Ordinary dutching covers only some outcomes: if none of them wins, the whole stake is lost.

Is dutching worth it?

It is a staking method, not an edge. If each price is fair or worse, dutching them does not change the expected result; it only makes the outcome of the selections you chose even.

Returned if any selection wins: 194.59 (+94.59)
If none of them wins: -100.00
Combined odds of the selections: 1.95 (implied 51.39%)

Dutching spreads one stake so every chosen selection returns the same. If the selections cover every outcome and the combined implied probability is under 1, it is a surebet.

The formula

stakeᵢ = total × (1/oddsᵢ) / Σ(1/odds) | return = total / Σ(1/odds)

Σ(1/odds) is the combined implied probability of your selections. Its inverse is their combined odds: backing all of them together is like backing one selection at those odds.

Simulated race: three runners at 4.50, 6.00 and 8.00, total stake 100. Σ = 0.2222 + 0.1667 + 0.125 = 0.5139, combined odds 1.95. Stakes: 43.24, 32.43, 24.32. Any of the three wins: about 194.59 back. None of them wins: -100.

Dutching and surebets

Cover every outcome of an event instead of a few, at the best price for each across books, and dutching becomes surebet staking. If Σ(1/odds) over every outcome is under 1, every result returns more than the stake. That is what the surebet calculator works out for 2 or 3 outcomes.

Things to check

Every selection has to be in the same event and settle under the same rules (non-runners, dead heats, void legs). Rounding stakes to whole numbers moves the returns apart slightly. And the odds must still be available when you place each bet: prices on several selections rarely all hold for long.

Prices that are still there

A calculator is only as good as the odds you type into it. Arbistoteles scans 10 crypto sportsbooks prematch and re-reads every leg of a surebet at its book before it shows as confirmed. The free account shows up to 3 live confirmed surebets of 0.99% or less.
