How do I find my real profit per Amazon product?
To find your real profit on an Amazon product, subtract Amazon's fees, your product cost (COGS), shipping and taxes from the selling price. Nusty Space does this per product, using the price and fees read from your account through Amazon's official API (SP-API) plus the cost you enter.
Which numbers back this calculation?
- Amazon states commissions of 10% to 15% for selling in Brazil, which come off the price before any of your costs. Amazon selling prices
- Account data is read through the Selling Partner API (SP-API), Amazon's official interface for sellers. SP-API documentation
