Amazon's product profit calculation covers multiple factors, including sales revenue, costs, fees, and exchange rates.

The following is the detailed calculation formula and explanation of Amazon product profits:

1. **Gross profit of a single product**:

- Gross profit = (single product sales - delivery fee - platform commission fee) * exchange rate - single product first-mile fee - product cost - product packaging - domestic shipping fee of product - other fees

2. **Total profit calculation**:

- Total profit = (sales revenue - advertising fees - storage fees ± Amazon fee adjustment) * exchange rate - total cost of products sold - logistics cost of products sold

3. **More detailed income and expenditure accounting**:

- **Income items**: sales + refunds + other income + compensation income

- **Expenditure items**: procurement cost, warehousing cost, delivery fee, sales commission, tax, sales promotion fee, storage fee, other expenses, etc. Each major category also includes many detailed expenses, such as advertising fees, flash sale fees, monthly storage fees, long-term storage fees, inventory removal fees, etc.

4. **FBM profit calculation** (Fulfillment by Merchant, that is, the seller ships the goods by himself):

- FBM profit = selling price - product procurement cost - domestic logistics shipping fee - product international logistics shipping fee - Amazon commission
