Estimate your Amazon FBA fees and profit per unit.
FBA Profit Details
What Is an FBA Cost Calculator?
An FBA Cost Calculator is a tool that helps Amazon sellers determine:
- Profit per unit – The money you earn after deducting product costs and Amazon FBA fees.
- Profit margin (%) – The percentage of your selling price that is profit.
Using this tool, you can evaluate whether your pricing strategy is viable or if adjustments are needed before investing in inventory.
Why FBA Cost Calculation Matters
Many Amazon sellers make the mistake of setting selling prices without fully understanding fees and costs. Amazon charges FBA sellers for:
- Fulfillment fees – Covers storage, picking, packing, and shipping products.
- Referral fees – A percentage of each sale that varies by category.
Failing to factor these into your calculations can turn a seemingly profitable sale into a loss. The FBA Cost Calculator prevents these surprises by giving you a clear picture of your net earnings.
How to Use the FBA Cost Calculator
Using this tool is simple and intuitive. Follow these steps:
Step 1: Enter Product Cost
Input the total cost to produce or purchase one unit of your product. Include manufacturing, shipping to Amazon, and any other upfront costs.
Example: $15 per unit.
Step 2: Enter FBA Fees
Input the total FBA fees associated with storing and fulfilling the item. Check your Amazon Seller Central account for accurate fees.
Example: $5 per unit.
Step 3: Enter Selling Price
Input the price at which you plan to sell your product on Amazon.
Example: $30 per unit.
Step 4: Click Calculate
The calculator instantly provides:
- Profit per unit – Selling price minus product cost and FBA fees.
- Profit margin (%) – Profit as a percentage of selling price.
The results appear instantly and are easy to read, helping you make informed decisions.

Example Calculation
Let’s run a sample calculation:
- Product Cost: $15
- FBA Fees: $5
- Selling Price: $30
Profit Calculation:Profit=SellingPrice−(ProductCost+FBAFees)=30−(15+5)=10
Profit Margin Calculation:ProfitMargin=(Profit/SellingPrice)×100=(10/30)×100=33.33%
Result: You make $10 per unit with a 33.33% profit margin.

Understanding Profit Margin
Profit margin is a critical metric for any Amazon seller. It tells you how much of each sale is pure profit after all costs are deducted. Higher margins mean more money to reinvest in marketing, inventory, or growth.
Profit Margin Formula:ProfitMargin(%)=SellingPriceProfitPerUnit×100

- Ignoring FBA fees – Leads to negative profit unexpectedly.
