E-commerce Profit Analysis: Making Hidden Costs Visible

E-Commerce Profit Analysis and Cost Optimization

Many sellers focus on revenue but what truly matters is profit margin.

E-Commerce Profit Formula

```

Gross Profit = Sale Price - COGS - Platform Fee - Shipping - Packaging

Operating Profit = Gross Profit - Advertising - Labor - Warehouse - Fixed Costs

```

Commonly Overlooked Costs

• Returns: Product refund + return shipping + reinspection
• Currency fluctuation: Exchange rate losses between purchase and sale currencies
• Long-term storage: FBA long-term fees or monthly warehouse charges
• Ad spend creep: Need continuous ROAS monitoring
