Amazon FBA calculator formula

The calculator uses the same profit structure sellers use when analyzing supplier files:

Net profit = Sale price
  - Referral fee
  - FBA fulfillment fee
  - Per-item and closing fees
  - Product cost
  - Inbound shipping
  - Prep cost
  - Storage estimate

If your supplier file starts with UPCs, EANs, or ISBNs, convert them first: UPC to ASIN, EAN to ASIN, or ISBN to ASIN.

For more detail on each fee type, read the Amazon seller fees guide. To pressure-test your sale price, check Amazon price history.

Frequently asked questions

Is this Amazon FBA calculator free?

Yes. You can calculate fees, profit, margin, and ROI for individual products for free. Bulk supplier file analysis is available inside Rocket Source.

How does the calculator estimate Amazon fees?

ASIN mode uses product and fee data for the selected marketplace. When you edit the sale price, referral fees are recalculated from the loaded fee rate so the page does not call the API on every keystroke.

What costs should I enter?

Enter your sale price, product cost, inbound shipping per unit, prep cost, and expected storage cost. The calculator subtracts those costs plus Amazon fees from the sale price.

Can I calculate fees for a supplier list?

This page is built for single-product checks. For supplier lists, Rocket Source can calculate profitability across thousands of ASINs from a CSV or spreadsheet.
