The decision
How much gross response is needed after the modeled leakage?
Source inputs
| Campaign / product | Expected baseline units | Promotion units | Regular / promotion price | Variable unit cost |
|---|---|---|---|---|
| Example travel pack Synthetic response leakage | 1,000 | 1,600 | €50 / €40 | €25 |
What to inspect
Open a row’s full contribution bridge, check the day-window alignment and cost allocation, then vary the expected baseline and response in Scenario studio. The portfolio result includes the recorded refunds, supplier support and displacement; unrecorded effects remain excluded.

Interpretation limits
The figures are generated from the same deterministic engine used by the workbench. They are not evidence from a merchant or a randomized test. A supplied baseline can make an offer look attractive or unattractive, so the baseline deserves the same scrutiny as the campaign’s realized sales.
How to read this case
Effective contribution is €10.50 per gross unit. The minimum gross volume is 2,409.52 units, or 2,410 whole units, under constant return/displacement rates.
Case-specific assumptions
- Returns give back full promotion revenue while all gross-unit costs remain unrecovered.
- The minimum-volume calculation holds return and supplied displacement rates constant.
