Amazon FBA Total Landed Cost Calculator

Most FBA sellers calculate margin wrong. They subtract the referral fee and fulfillment fee from the selling price and call it profit. But the real cost of selling on Amazon starts before the product reaches the warehouse. COGS, inbound shipping, import duty, prep fees, inbound placement, storage, and returns all come before net profit. This calculator puts every cost in one place and tells you before you order inventory whether the numbers work.
