Start with the decision

What contribution remains per promoted sale under the entered fee assumptions?

Small online sellers considering a product promotion.

From input to next step.

  1. 01

    Set the unit basis

    Enter list price and full variable unit cost consistently. Include seller-paid fulfilment in cost if it applies to the same selling-price basis.

  2. 02

    Add promotion assumptions

    Enter the discount, percentage fee, fixed fee and per-unit campaign allowance. Use the provider’s actual fee basis rather than assuming every fee is on the same amount.

  3. 03

    Review the remaining contribution

    Check a higher-cost scenario and the capacity required to deliver it. Fixed campaign costs need their own separate break-even assessment.
