Selling on Amazon can feel exciting—millions of shoppers, global reach, and endless growth opportunities. But here’s the biggest challenge every seller faces:
👉 “How much profit will I actually make after Amazon fees?”
Amazon charges multiple fees, including referral fees, fulfillment costs, storage charges, and closing fees. If you don’t calculate them correctly, your margins can vanish before you even make a sale.
That’s why the Amazon Selling Fee Calculator exists. It’s a free tool that breaks down your costs, helping you see your true profit per product.

How to Use the Amazon Selling Fee Calculator
Here’s a step-by-step guide:
Step 1: Access the Calculator
Search “Amazon Selling Fee Calculator [your region]” on Google (e.g., US, UK, Canada).
Step 2: Enter Product Details
You can search by:
- ASIN, UPC, ISBN, or product name.
Step 3: Enter Selling Price
Input the price you plan to sell at.
Step 4: Add Costs
- Cost of Goods Sold (COGS) – Your purchase/manufacturing cost.
- Shipping Costs – To Amazon (FBA) or to customers (FBM).
- Additional Expenses – Packaging, labeling, duties.
Step 5: Compare Fulfillment Options
The calculator shows:

Step 6: Review Results
You’ll see:
- Total Amazon fees
- Net revenue per unit
- Profit margin percentage
Example: Selling a Coffee Mug
Let’s say you’re selling a ceramic coffee mug for $19.99.
- COGS: $5
- Shipping to Amazon: $1 per unit
- Amazon Referral Fee (15%): $3
- FBA Fulfillment Fee: $4.50
- Storage Fee: $0.20
Calculation:
$19.99 – ($5 + $1 + $3 + $4.50 + $0.20) = $6.29 net profit
Profit Margin = 31.4%
👉 Without the calculator, you might think you’re making $15 profit—but in reality, it’s only $6.29.
