How to read the results
- Net profit / unit is what you keep after every cost and fee on a single sale.
- Margin is net profit as a percentage of the sale price — a quick health check on the price.
- ROI is profit against the cash you tie up per unit (product cost + inbound shipping).
- Break-even price is the lowest sale price where you don't lose money, accounting for the percentage referral fee.
