Revenue feels like profit — it isn't
Your Amazon payout already has fees taken out, and it does not show ad spend at all. So the money landing in your account is not your profit — it is revenue minus some fees, before advertising and returns. That gap is where sellers fool themselves.
The costs that hide your margin
Referral and FBA fees (often 25–40% of price), storage, returns, and ad spend that never shows on your payout. Add them all and the real number is usually far thinner than it looks. The FBA fees guide breaks each down; the profit calculator does the math for one product.
See it per product, not blended
A blended account margin hides losers behind winners. Profit per SKU reveals which products actually make money and which to fix, reprice or stop advertising. That is what profit reports compute automatically — after every fee, return and ad cost.
