About
About this tool
Selling on Amazon means several deductions from every sale: the referral fee (a percentage of the selling price that depends on your category), fulfilment or FBA fees, shipping, advertising and, in India, the GST already included in your price. This calculator stacks them up so you can see what you actually keep.
Enter ad costs either per unit or as TACoS (total advertising cost of sale: ad spend ÷ total sales). The break-even price accounts for fees and tax that grow with the price, so it's the true minimum you can charge without losing money on each unit.
The 15% referral fee is only an example. Amazon's rates vary by category, marketplace and price band, and change from time to time. Always check the current fee schedule in Seller Central, and allow for returns and storage fees on top.
