Selling on Amazon sounds simple—you buy a product, list it, and make a profit. But the truth is, Amazon’s fee structure can be complex, and many sellers overestimate how much they’ll actually make.
That’s where the Amazon Profit Calculator comes in. It’s a simple yet powerful tool that shows you exactly what your net profit and profit margins will be after Amazon deducts its referral fees, fulfillment costs, and storage charges.
Instead of guessing, you’ll know your numbers before you invest in inventory.
What is the Amazon Profit Calculator?
The Amazon Profit Calculator (sometimes called the FBA calculator or product calculator) is an online tool provided by Amazon that allows sellers to:
- Estimate fees (referral fees, fulfillment fees, storage).
- Compare FBA vs. FBM profitability.
- Factor in cost of goods (COGS) and shipping.
- Calculate net profit per unit.
- See profit margins (%) and ROI.
It’s especially helpful during product research, when deciding whether to sell a new product.
Why Do You Need It?
Many new sellers make a mistake:
They assume that if they buy a product for $10 and sell it for $30, they’ll make a $20 profit.
But here’s reality with Amazon fees included:
- Referral Fee (15%): $4.50
- FBA Fee: $3.20
- Storage Fee: $0.25
- Product Cost (COGS): $10
- Shipping to Amazon: $1
Actual Profit = $30 – ($10 + $1 + $4.50 + $3.20 + $0.25) = $11.05
Instead of $20, you’re making closer to $11. Without the calculator, it’s easy to misjudge profitability.
How to Use the Amazon Profit Calculator
Here’s a step-by-step guide:
1. Open the Calculator
Go to Amazon’s official Profit Calculator for your region (US, UK, Canada, etc.).
2. Search for Product
Enter the ASIN, UPC, ISBN, or product name.
3. Enter Your Price
Type the price you plan to sell the product for.
4. Add Costs
- Product cost (COGS)
- Shipping to Amazon (FBA) or direct to customer (FBM)
- Any prep or packaging fees
5. Choose Fulfillment Method
- FBA (Fulfillment by Amazon) – Amazon handles storage, packing, and shipping.
- FBM (Fulfillment by Merchant) – You handle fulfillment yourself.
6. Review Results
The calculator shows:
- Amazon referral fee
- Fulfillment fee (if FBA)
- Storage cost
- Net profit per unit
- ROI and profit margin
Example: Selling a Yoga Mat
Let’s say you want to sell a yoga mat for $35.
- Selling Price: $35
- COGS: $9
- Shipping to Amazon: $1.50
- Referral Fee (15%): $5.25
- FBA Fee: $6.00
- Storage Fee: $0.40
Net Profit = $35 – ($9 + $1.50 + $5.25 + $6.00 + $0.40) = $12.85
Profit Margin = 36.7%
That’s a healthy margin, but if competition forces you to drop the price to $29, profit drops to just $6.85.
