← Amazon FBA vs FBM calculator
Amazon publishes its own free fee-estimation tool for sellers, the FBA Revenue Calculator, reachable from Seller Central at sellercentral.amazon.com/fba/profitabilitycalculator and described at sell.amazon.com/blog/how-to-use-fba-calculator. It looks up an existing catalog listing, or lets you define a new one by category, dimensions, weight, and price, and estimates the fees for that one product.
That makes it the right tool for one job: the exact fee Amazon will actually charge on a specific listing right now. It reads Amazon's live schedule, so it is authoritative in a way no third-party page, including this one, can be — fee schedules change by category, size tier, and season, and this site does not publish Amazon's current numbers or claim to. If you need the current fee for a real ASIN, that is the tool to open, and every page on this site says so.
| Question | Where to answer it |
|---|---|
| What will Amazon actually charge on this exact listing? | Amazon's own Revenue Calculator — it is the live source. |
| Given my own cost of goods and shipping, does FBA or FBM leave more? | This calculator — both paths on one screen, from the rates you enter. |
| What is the most I can pay a supplier before this unit loses money? | This calculator's max buy cost, next to both fulfillment paths. |
| Does a coupon, Subscribe & Save, a supplier MOQ, Vine, aged inventory, AWD, Remote Fulfillment, or peak-season timing still pay on this same listing? | This calculator's linked follow-on pages — see what this checks below. |
Beyond the fee lookup, this tool also keeps named sourcing scenarios in
your own browser so you can switch between them without retyping, and a
shareable link that carries your inputs after the
# in the URL — never uploaded anywhere, and reproduced only
in whoever's browser opens that link.
This tool needs no Amazon account, no Seller Central sign-in, and no catalog listing to already exist: it is a static page, the arithmetic runs in your browser, and once it has loaded it keeps working with the connection off. Nothing you type is uploaded anywhere.
Most sellers get more use out of both. Amazon's own Revenue Calculator, inside Seller Central, is the authoritative source for the exact fee Amazon will charge on a specific listing, because it reads Amazon's live fee schedule for that product. This page does not try to replace that lookup. What it adds is the decision Amazon's calculator is not built around: whether FBA or FBM nets more on your own cost of goods and shipping, the most you can pay a supplier before the unit loses money, and around a dozen follow-on decisions on the same listing, from Amazon Vine to peak-season storage timing, none of which are fee lookups.
