Dutching Calculator

Scope of this calculation

The headline Dutching allocation is determined directly by Total stake and Outcome A decimal odds; the remaining fields supply the comparison or adjustment required for Dutching.

What each entry represents

Calculation method and assumptions

In the current scenario, the calculation uses stake share is proportional to the inverse of each outcome price.

Checks the arithmetic cannot perform

At this stage, cash, restricted credit, gross return, and net profit may require separate accounting.

Following the calculation

For this market, the example is a formula check rather than a recommended wager.

Total stake is $315. Outcome A decimal odds is 3.648. Outcome B decimal odds is 4.428. Outcome C decimal odds is 5.17.

Applying the Dutching rule: stake share is proportional to the inverse of each outcome price.

• Outcome A stake: $124.53
• Outcome B stake: $102.60

For this dutching allocation example, a mismatch usually comes from units, rounding, a sign error, or a different option selection. In this model, check those items first.

Keep stake, net profit, and total return under one convention.

Promotional credits may need different treatment from cash.

Scenario testing

• Keep stake fixed and compare the accepted price with one realistic adverse quote.
• For promotions or hedges, test the actual eligible maximum.
• Do not change multiple prices when identifying the source of a return difference.

Settlement and data limitations

• The selected outcomes must cover the intended settlement possibilities.
• For this market, review promotion terms, limits, push treatment, void rules, and whether stake is returned before comparing profit.
• Under the entered assumptions, historical fit does not guarantee the current competition follows the same process.

Recalculation triggers

In the current scenario, keep current availability separate from the stored estimate.

How to challenge the displayed answer

Check whether Total stake and Outcome A decimal odds are independent pieces of information. If one was derived from the other, using both as separate adjustments may exaggerate the same signal. Keep the simpler case as a reference and document why any additional adjustment belongs in the calculation.

The output should be recalculated after a material change to Outcome A decimal odds, Outcome B decimal odds, participant status, event format, or quoted market. Minor display rounding is not a material change. Preserve the previous Dutching allocation so the effect of new information can be distinguished from a changed calculation method.

Use Dutching allocation within the limitations of the displayed formula: stake share is proportional to the inverse of each outcome price. The equation organizes the entered assumptions; it does not model every path an event can take. Unlisted factors should be discussed separately instead of being hidden inside an unrelated numeric field.

Begin the review with Outcome C decimal odds, because it establishes one boundary of the scenario. Compare its source period with Total stake and write down any difference. If the two inputs describe unlike samples, rebuild the case before treating Dutching allocation as an event-level comparison.
