Example Calculation

Let’s see how the calculator works with a real example.

Product Details

Selling Price: $30
Product Cost: $8
Shipping Cost: $2
Amazon Referral Fee: 15%
FBA Fulfillment Fee: $4
Storage Fee: $0.50
Other Costs: $1

Step 1: Calculate Amazon Fee

Amazon fee =
$30 × 15% = $4.50

Step 2: Calculate Total Cost

Total Cost =
Product Cost + Shipping + FBA Fee + Storage + Other Costs + Amazon Fee

Total Cost =
8 + 2 + 4 + 0.50 + 1 + 4.50 = $20

Step 3: Calculate Profit

Profit =
Selling Price – Total Cost

Profit =
30 – 20 = $10

Step 4: Profit Margin

Profit Margin =
(Profit ÷ Price) × 100

Profit Margin =
(10 ÷ 30) × 100 = 33.33%

Final Result

Total Amazon Fee: $4.50
Total Cost: $20
Estimated Profit: $10
Profit Margin: 33.33%

This is a strong margin for an Amazon product.

What Is a Good Amazon FBA Profit Margin?

Most experienced Amazon sellers aim for:

Minimum profit margin: 20%
Ideal margin: 30–40%

A higher margin protects your business from:
