What it does
Know what you really keep on each Amazon FBA sale before you buy stock. Enter your price and costs and get the full cost breakdown, profit margin, break-even point and a suggested price for the margin you want. You list the selling price, product cost, shipping to FBA, FBA fulfilment fee, monthly storage, ad spend as a share of sales and your category. The calculator adds the referral fee and works out profit per unit. Use it for a new product, a diagnosis of a slow seller, a price change, or a batch table that compares many SKUs side by side. It runs on your numbers alone and needs no API key.
