What Is an Amazon FBA Calculator?
An Amazon FBA Calculator is an online tool used by Amazon sellers to estimate profits and fees associated with selling products through the Fulfillment by Amazon (FBA) program.
Amazon FBA allows sellers to store products in Amazon warehouses while Amazon handles:

- Returns
Although this service is convenient, Amazon charges various fees that can significantly impact your earnings. The calculator helps sellers estimate those costs and determine whether a product is worth selling.

Practical Example of Amazon FBA Calculation
Let’s say you want to sell a kitchen product on Amazon.
Product Details
| Expense Type | Amount |
|---|---|
| Selling Price | $50 |
| Product Cost | $18 |
| Amazon Referral Fee | $7.50 |
| FBA Fee | $6 |
| Shipping Cost | $2 |
| Packaging Cost | $1.50 |
Calculation
Total Expenses:
$18 + $7.50 + $6 + $2 + $1.50 = $35
Net Profit:
$50 - $35 = $15
Profit Margin:
15 ÷ 50 × 100 = 30%
ROI:
15 ÷ 35 × 100 = 42.85%
This means the product generates a healthy return and may be worth selling.
