How FBA profit is calculated
Net profit = sale price − referral fee − FBA fulfillment − monthly storage − product cost − inbound shipping − ad cost. Break-even ACOS is your pre-ad profit as a share of price — the highest ad cost ratio you can bear before the product loses money.
The practical threshold we use on our own brands: product cost + inbound shipping under 30% of the sale price. See the fee lines in detail in the FBA costs article.
