HOW IT WORKSNet proceeds = buyer-paid revenue − fees − shipping − packaging − other variable costs.Net profit = net proceeds − purchase cost. Inventory ROI uses purchase cost; margin uses gross buyer-paid revenue.
EXPLORE DIGITAL RESOURCES →MARGIN VS ROI
Margin compares profit with buyer-paid revenue. Inventory ROI compares profit with purchase cost. Use both; they answer different questions.
COSTS STAY EXPLICIT
