How to calculate your real Amazon profit

Revenue is not profit. From your selling price you subtract the Amazon referral fee (usually around 15%), the FBA fulfilment fee, your cost of goods, inbound shipping, the share of PPC spend and your returns. What remains is your profit per unit — and exactly this number, automatically across every order and product, is what Faktor400 delivers with the TrueProfit engine.
