Calculation Logic / Formula
The Amazon Sellers Calculator works using a structured formula:
Total Cost = Product Cost + FBA Fee + Referral Fee + Shipping + Additional Expenses
Net Profit = Selling Price − Total Cost
Profit Margin % = (Net Profit ÷ Selling Price) × 100
ROI % = (Net Profit ÷ Product Cost) × 100
This helps sellers evaluate whether a product is financially viable before listing.

Practical Example
Let’s assume you are selling a kitchen gadget:
- Selling Price: $50
- Product Cost: $20
- Amazon Referral Fee (15%): $7.50
- FBA Fee: $5
- Shipping Cost: $3
- Additional Costs: $2
Step-by-step calculation:
Total Cost = 20 + 7.5 + 5 + 3 + 2 = $37.5
Net Profit = 50 − 37.5 = $12.5
Profit Margin = (12.5 ÷ 50) × 100 = 25%
So, your final profit per unit is $12.5 with a 25% margin.
