Estimate your Amazon FBA fees, total selling costs, net profit and profit margin before you buy inventory or set your price.
Enter your product economics below and adjust the fee assumptions to match your Amazon marketplace and seller account. SellerCalc is an independent planning tool; actual Amazon fees can vary by category, size, weight, marketplace and account.
This calculator helps you model the economics of an Amazon FBA product in one place. Use it before sourcing, launching, repricing or reordering inventory.
Amazon FBA costs are not one flat fee. Your economics can include selling fees, fulfillment, inventory storage and other services or operating expenses. Referral fees can vary by product category, while fulfillment costs depend on factors such as size and weight.
That is why looking only at the product selling price can give you a misleading picture of profitability. A product that looks attractive at $50 may have a very different margin after marketplace and fulfillment costs are included.
The referral fee is generally calculated from your selling price, with the applicable percentage depending on the category and marketplace. Check Amazon's current fee schedule for the exact rate that applies to your product.
FBA fulfillment covers the operational work of picking, packing and shipping an order. The applicable fee depends on the product's fulfillment characteristics, including size and weight.
Inventory storage, inbound shipping, advertising, returns, preparation and other costs can materially change your final margin. Add the costs that apply to your business instead of relying on revenue alone.
A useful starting formula is:
Net Profit = Selling Price − Amazon Fees − Product Cost − Fulfillment − Other Costs
For example, if a product sells for $50, costs $15 to source, and your combined Amazon and operating costs are $16.50, the estimated profit is $18.50 per unit. Your profit margin is then $18.50 ÷ $50 = 37%.
Use the calculator above to replace these example assumptions with your own numbers.
FBA is not automatically the most profitable fulfillment method. Compare your estimated FBA economics with the cost of fulfilling orders yourself, especially for products with unusual dimensions, low margins or high storage requirements.
Model landed costs and margins before placing a manufacturing order.
Check whether your buy cost leaves enough room after Amazon fees and fulfillment.
Quickly test a product's potential margin before purchasing inventory.
No. SellerCalc is an independent planning tool. Use Amazon's current fee schedule and Revenue Calculator to verify fees before making a business decision.
Yes. SellerCalc's calculator is free to use and does not require an account.
At minimum, consider the applicable selling/referral fee, FBA fulfillment cost, product cost and shipping. Depending on your business, also account for storage, advertising, returns, preparation and other operating expenses.
Not always. The better option depends on your product, fulfillment costs, storage needs, sales volume and operating setup. Compare both scenarios before committing to a fulfillment method.
