Frequently Asked Questions
How do you measure promotion profitability?
Compare promo profit ((Promo Price - Cost) x Promo Units) against baseline ((Regular Price - Cost) x Baseline Units). A promo wins only when volume uplift outweighs the per-unit margin given up.
What is break-even promo volume?
Break-Even Units = Baseline Profit / (Promo Price - Unit Cost). A $12,600 baseline with $21.99 promo contribution needs 574 promo units. Forecast honestly against that line before approving creative.
How deep should promo discounts be?
Routine promos 10-20%, events 20-35%, clearance up to 50%+. Match depth to intent: retention needs less than acquisition, and acquisition needs less than liquidation.
Do promotions hurt future full-price sales?
Yes when overused — shoppers learn to wait (pull-forward) and reference prices drop. Cap major promos at 6-8 weeks per year and protect hero SKUs with bundles instead of straight cuts.
Should marketplace fees be included in promo math?
Always: fees scale with the discounted price, and Lightning Deals or promoted placements add fees. Recompute contribution at the promo price net of every variable deduction.
