Seller Central Profit Calculator
Running an Amazon business through Seller Central requires more than just listing products and waiting for sales. One of the most important aspects of building a profitable Amazon store is understanding your actual earnings after all costs and fees are deducted.

Practical Example
Let’s assume:
- Selling Price = $50
- Product Cost = $20
- Amazon Referral Fee (15%) = $7.5
- FBA Fee = $5
- Shipping = $2
- Advertising = $4
- Storage & Returns = $1.5
Calculation:
Total Costs = 20 + 7.5 + 5 + 2 + 4 + 1.5 = $40
Net Profit = 50 – 40 = $10
Profit Margin = (10 ÷ 50) × 100 = 20%
ROI = (10 ÷ 40) × 100 = 25%
Result:
- Net Profit: $10
- Profit Margin: 20%
- ROI: 25%
This shows the product is profitable but with moderate margins.
