Free Amazon Fee Estimate calculator with clear step-by-step results.
Stacks the three fees Amazon charges an FBA seller on a single unit - the category referral commission, the size-tier fulfilment fee and monthly storage - then subtracts your landed cost so you can see whether the listing price clears a workable margin.
Amazon fees
Fees = price x referral rate + fulfilment fee + storage fee
Unit profit
Profit = price - fees - landed cost of goods
Amazon's fee schedule changes regularly and varies by marketplace, category and product size tier. Treat this as a planning estimate and confirm against your current Seller Central fee preview.
Most categories are 15%, but rates run from 8% on some electronics to 45% on accessory devices. Check the current fee schedule for your exact category.
Amazon bills storage by cubic foot per month across your whole inventory. Dividing your monthly storage bill by units held gives a per-unit figure that can be compared against a single sale.
