Most sellers can name the referral fee. Almost none know the total Amazon takes once fulfillment stacks on top. Enter four things and see every fee that comes out before your product cost even enters the picture.
Total fees · referral · fulfillment · what's left
Estimates use the current published FBA rate card for referral and fulfillment by size tier. Your exact fee can vary by sub-category and dimensional weight. The left-after-fees number is before your product and inbound cost. Confirm final fees in Seller Central before a large purchase order.
Want this fee breakdown in your inbox, plus the 3 levers that shrink your fee stack the fastest?
Every seller knows the referral fee. Fifteen percent, off the top, done. So they price around that one number and feel safe.
Then the fulfillment fee lands. On a small standard unit that's three or four dollars. On anything large or heavy it's five, six, nine dollars, sometimes more than the referral fee itself. Stack them together and Amazon can take a third of your sale price before a single dollar of product cost is counted.
You can't price a product you haven't fully costed. This calculator lays the whole fee stack out in one pass so the number stops surprising you at disbursement time.

It's driven by your size tier and unit weight. Enter dimensions and weight and the tool assigns the tier automatically, then applies the current published fulfillment rate. Bigger and heavier units cost more to pick, pack, and ship.
