Amazon FBA Profit Calculator
Selling on Amazon has become one of the most profitable online businesses in recent years. But as every Amazon FBA (Fulfilled by Amazon) seller knows, profits aren’t as straightforward as “sale price minus product cost.” Between referral fees, FBA storage costs, shipping charges, and hidden expenses, your true profit margin can be difficult to determine.
That’s where the Amazon FBA Profit Calculator comes in — a free tool designed to help Amazon sellers accurately calculate their profits, margins, and ROI before they list or source a product.
What Is the Amazon FBA Profit Calculator?
The Amazon FBA Profit Calculator is an online tool that helps Amazon sellers calculate their:
- Net profit
- Profit margin
- ROI (Return on Investment)
- Estimated fees
- Total cost per unit
It takes into account all the key costs sellers face on Amazon FBA, including:
- Referral fees
- FBA fulfillment fees
- Product cost
- Shipping to Amazon warehouse
- Storage costs
With one click, sellers can find out if a product is worth selling — or if they’ll lose money after Amazon takes their cut.
Why Use an FBA Profit Calculator?
If you’re serious about Amazon selling, you need to know your numbers before sourcing products. Guesswork leads to:

- Lost time and resources
With our calculator, you can:
- Estimate profits before you buy

- Save money by seeing true costs upfront
How the Amazon FBA Profit Calculator Works
Our calculator uses the following inputs to calculate your results:
- Product Sale Price – What you plan to sell it for on Amazon
- Product Cost – How much you pay to source the item
- Shipping to Amazon – Per unit cost to ship it to Amazon’s warehouse
- Amazon Referral Fee – A % of the sale price (usually 15% for most categories)
- FBA Fulfillment Fee – Based on item size, weight, and category
- Monthly Storage Fee (optional) – If you’re holding inventory for long durations
And outputs:
- Net Profit
- Profit Margin %
- ROI %
- Total Amazon Fees
Example Amazon FBA Profit Calculation
Let’s say you’re selling a product for $30.
| Input | Amount |
|---|---|
| Product Cost | $8.00 |
| Shipping to Amazon | $2.00 |
| Referral Fee (15%) | $4.50 |
| FBA Fee (standard size) | $3.00 |
| Monthly Storage (avg.) | $0.25 |
Total Cost = $8 + $2 + $4.50 + $3 + $0.25 = $17.75
Net Profit = $30 – $17.75 = $12.25
Profit Margin = 40.8%
ROI = 122.5%
Without a tool like this, you’d likely underestimate costs and overestimate profits.

Understanding the Amazon FBA Fee Structure
To accurately assess profitability, sellers must know each cost component:
Referral Fees
Amazon charges a percentage on each sale, depending on the product category—commonly around 15 percent. Items like books, electronics, and toys may have slightly different referral rates.
FBA Fulfillment Fees
These cover picking, packing, and shipping. Fees vary based on item size and weight. For example, standard-size items typically incur lower fees than oversized ones.
Inventory Storage Fees
Sellers pay monthly storage fees based on volume held. Long-term storage (over 365 days) incurs higher “long-tail” fees. Choose average or peak monthly storage rates depending on your sales pattern.
Shipping Costs to Amazon
Suppliers typically ship inventory to Amazon FBA’s distribution centers. These costs depend on factors like weight, shipping method, and origin country. Use per-unit shipping cost estimates.
Return Processing Fees
If items are returned, Amazon may charge a return processing fee based on the category. Refund reimbursements usually equal the refund amount minus this fee.
Other Possible Fees
Additional costs may include removal or disposal fees, dangerous goods handling, unplanned service fees, and label charges.
