Book under 100% — this is an arbitrage: you profit whichever selection wins.

Dutching is backing more than one outcome in the same event, sized so the return is identical no matter which of your selections comes in. It turns several individual prices into one combined position — useful when you can narrow a race to two or three live contenders but cannot separate them.

Each selection's share of the stake is proportional to its implied probability — one divided by its decimal odds — so shorter prices get more of the stake. The combined return is your total stake divided by the sum of those implied probabilities. If that sum is below 100% you have found an arbitrage and lock a profit whatever happens; if it is above 100%, which is normal, you are accepting a defined loss on the losers in exchange for a single clean payout.

FAQ

When is dutching better than an each-way or multiple bet?
When you have a strong opinion on a small group of outcomes rather than a single one. Dutching two selections at 3.0 and 4.0 gives a smoother result than picking one and being wrong half the time, at the cost of a lower payout when you are right.
What does the book percentage tell me?
It is the sum of the implied probabilities of your selections. Under 100% is a guaranteed profit (an arb). Over 100% means you will lose the difference on average — the further over, the worse the value.
Can I dutch for a fixed target profit instead of a fixed stake?
Yes. Switch the mode to target return and enter the amount you want back; the calculator sizes each stake to hit it and shows the total outlay required.
