Selling on Amazon is exciting—but it’s also easy to underestimate the true costs. Many sellers list products thinking they’ll earn big profits, only to see Amazon’s referral fees, storage charges, and fulfillment costs eat into their margins.
The solution? The Amazon FBA Fees Calculator. This tool helps sellers calculate all Amazon-related costs before launching a product, so they can set the right price and avoid losing money. Whether you’re a beginner or an experienced seller, this calculator is your safety net for smart pricing and long-term success.
What is the Amazon FBA Fees Calculator?
The Amazon FBA Fees Calculator is a free tool offered by Amazon (and available from third parties) that estimates:
- 📦 Fulfillment Fees – picking, packing, and shipping orders.
- 💲 Referral Fees – Amazon’s commission, usually 8–15% of sale price.
- 🏬 Storage Fees – monthly or long-term storage in Amazon warehouses.
- 💰 Total Costs & Net Profit – after factoring in your cost of goods and shipping to Amazon.
In short, it shows you exactly how much money you’ll actually make per unit sold.
How to Use the Amazon FBA Fees Calculator
Here’s a simple step-by-step guide:
1. Open the Calculator
Go to the Amazon Revenue & FBA Fees Calculator for your country (e.g., US, UK, Canada).
2. Enter Your Product
Search by ASIN, product name, or category to pull product data.
3. Add Your Selling Price
Type the price you intend to list the item at.
4. Input Costs
- Cost of Goods (COGS) – what you pay to source or manufacture.
- Shipping to Amazon warehouse – logistics or freight cost.
- Optional prep costs – labeling, packaging, etc.
5. Compare FBA vs. FBM
The calculator shows costs for:
- FBA (Fulfilled by Amazon)
- FBM (Fulfilled by Merchant, where you ship items yourself)
6. Review Results
You’ll see a breakdown of:
- Referral fee
- Fulfillment fee
- Storage cost
- Net profit & margin
Example: Selling a Phone Case
Let’s say you want to sell a phone case on Amazon:
- Selling Price: $15
- Cost of Goods: $3
- Shipping to Amazon: $1
- Referral Fee (15%): $2.25
- FBA Fulfillment Fee: $3.50
- Storage Fee: $0.05
Net Profit = $15 – ($3 + $1 + $2.25 + $3.50 + $0.05) = $5.20
Profit Margin = 34.6%
Without the calculator, you might assume $12 profit. But after fees, it’s closer to $5.
