Selling on Amazon is one of the fastest ways to build an e-commerce business—but it’s also full of hidden costs. Many sellers are surprised when their expected $15 profit turns into just $5 (or worse, a loss) after Amazon takes its share.
The truth is: Amazon charges multiple fees, and they vary depending on product size, category, and fulfillment method. To avoid nasty surprises, you need the Amazon Fees Calculator.
This free tool gives you a clear breakdown of Amazon’s selling fees, fulfillment charges, storage costs, and net profit, so you know exactly what you’ll earn before you list a product.
What is the Amazon Fees Calculator?
The Amazon Fees Calculator is an online tool that helps sellers:
- Estimate Amazon’s referral fees.
- Calculate FBA (Fulfillment by Amazon) charges.
- Factor in monthly storage fees.
- Compare FBA vs. FBM (Fulfilled by Merchant) costs.
- See net profit and margin per sale.
It’s Amazon’s way of helping sellers set realistic prices and avoid underestimating costs.
Types of Amazon Fees You Need to Know
Before using the calculator, let’s break down the main fees it covers:
1. Referral Fees
- Amazon’s commission on every sale.
- Usually 8–15% of the product price (varies by category).
2. FBA Fulfillment Fees
- Covers picking, packing, shipping, and customer service.
- Based on size and weight of the product.
3. Monthly Storage Fees
- Charged per cubic foot of storage space in Amazon warehouses.
- Higher during October–December (Q4 holiday season).
4. Optional Service Fees
- Labeling, prepping, disposal, or removal of inventory.
The calculator includes all of these fees to show the real profitability of a product.
How to Use the Amazon Fees Calculator
Here’s a simple step-by-step guide:
Step 1: Open the Calculator
Amazon provides region-specific calculators for each marketplace.
Step 2: Find Your Product
Enter the ASIN, UPC, or product name to pull up details.
Step 3: Enter Selling Price
Input your intended retail price.
Step 4: Add Your Costs
- Cost of Goods Sold (COGS).
- Shipping costs to Amazon.
- Any extra prep/packaging expenses.
Step 5: Choose Fulfillment Method
Select FBA or FBM.
Step 6: Review the Fee Breakdown
The calculator will display:
- Referral fee
- FBA fee
- Storage fee
- Net profit and margin
Example: Selling a Yoga Mat
Suppose you’re planning to sell a yoga mat for $30.
- Selling Price: $30
- Product Cost: $8
- Shipping to Amazon: $2
- Referral Fee (15%): $4.50
- FBA Fee: $5.25
- Storage Fee: $0.15
Net Profit = $30 – ($8 + $2 + $4.50 + $5.25 + $0.15) = $10.10
Profit Margin = 33.6%
Without the calculator, you might expect a $20 profit. In reality, it’s half that.
