Practical Example
Let’s understand with a real-world example:
- Selling Price: $50
- Product Cost: $20
- Amazon Referral Fee: 15% ($7.5)
- FBA Fee: $5
- Shipping to Amazon: $3
Calculation:
Total Costs = 20 + 7.5 + 5 + 3 = $35.5
Net Profit = 50 − 35.5 = $14.5
ROI = (14.5 ÷ 20) × 100 = 72.5%
Profit Margin = (14.5 ÷ 50) × 100 = 29%
Result:
This product generates a strong profit margin and is a good candidate for selling.
