Amazon Profit Analyzer

This breaks down Amazon profitability the way you'd actually need it: complete waterfall from revenue through every fee layer (FBA, referral, long-term storage, returns) down to true net margin. It calculates break-even ACoS, flags hidden costs like reimbursement gaps and unsellable return inventory, and works at both single-ASIN and portfolio level. The structured follow-up questions keep it fast without needing a spreadsheet first. What's useful is it doesn't stop at gross margin like most calculators. It includes advertising, return costs, and all the Amazon-specific fees that quietly eat into profit, then ranks optimization opportunities by actual dollar impact. Good for sanity-checking products before scaling or finding which SKUs are secretly losing money.
