Wholesale ROI is how experienced FBA wholesalers measure whether a product is worth buying. It tells you how efficiently you're deploying capital — a 50% ROI means every £100 you spend buying inventory returns £150 when sold. For a business that turns inventory 4 times a year, that's 200% annual return on capital.
Most professional wholesale sellers won't buy a product below 30% ROI after fees. The extra margin provides buffer for unseen costs, slow periods, and price erosion. Products with 50%+ ROI consistently are the backbone of a scalable wholesale operation.
