Amazon FBA Profit Calculator

Two hit every FBA sale: the referral fee (a percentage of the sale price, 15% in most categories, 8% in a few like consumer electronics) and the FBA fulfillment fee (a fixed per-unit charge based on size tier and weight). Monthly storage, inbound placement, and returns processing fees exist too but accrue separately — add an estimate to COGS for a fully-loaded view.

Look up the item in Seller Central's Revenue Calculator or the fee preview report — the fee is set by the product's size tier and shipping weight, not its price. Small standard-size items run roughly $3–$4.50, large standard $4.50–$7, and oversize climbs fast. Enter the exact figure here; a 50-cent error per unit is a full margin point on a $50 product.

A common working rule is thirds: one third product cost, one third Amazon fees, one third gross profit — roughly a 30–35% pre-ad margin. Below 20% there is rarely room for PPC, returns, and storage. If this calculator shows a thin margin at your target price, the product usually needs a lower landed cost or a higher price point, not better ads.

Yes — Amazon adjusts referral percentages, FBA fulfillment fees, and storage rates regularly, often annually and sometimes by category. The defaults here reflect typical 2026 US rates, but both fee fields are editable: check the current fee schedule in Seller Central before trusting any per-unit profit number for a launch or reorder decision.

It answers the same question. Amazon's own "FBA Revenue Calculator" and the fee-preview report in Seller Central both estimate net proceeds after the referral and FBA fulfillment fees — exactly what this Amazon FBA revenue and profit calculator does, without a login. Use Seller Central's report to read the exact fulfillment fee for a specific ASIN (it knows the real size tier), then enter that number here to model price and cost changes instantly.
