Amazon FBA profit: common questions

How do I calculate Amazon FBA profit?

Net profit per unit = sale price − referral fee − FBA fulfillment fee − storage fee per unit − landed cost (product, packaging, freight, duty) − ad spend per unit − cost of returns. Most sellers stop after the referral and fulfillment fees, which is why a product that looks like a 25% margin is often 8–12% once storage, ads and returns are included.

Is this FBA profit calculator really free?

Yes — completely free, forever. No signup, no credit card, no free trial. Just enter your numbers and get your real profit margin instantly.

What Amazon fees does this calculator include?

This calculator includes: referral fee, FBA fulfillment fee (by size tier), monthly FBA storage, return processing fee, inbound shipping, AWD costs, import tariffs (including US-China Section 301), PPC/TACoS spend, and full COGS breakdown including manufacturing, packaging, and freight.

How does the ASIN lookup work?

Enter any Amazon ASIN and the calculator automatically pulls the current sale price, product dimensions, FBA fee estimate, and inventory data from Amazon's systems — so you don't have to look anything up manually.

Does this calculator account for tariffs?

Yes. Select your country of origin and enter your tariff rate. The calculator includes a link to the HTS lookup tool for exact rates, and supports US-China Section 301 tariff rates.
