Calculate Amazon fees

Enter selling price, quantity, shipping charged, product cost, fulfilment cost, the referral fee rate, and any per-item plan fee. Use the category-adjustable rate when the Amazon fee structure changes by product line.

Item sale price Selling price per unit before Amazon fees. Quantity sold Used for plan fees and order-level economics. Shipping charged to buyer Included in the sales total for fee modeling. Product cost per unit Direct product or sourcing cost per unit. Fulfilment cost per order FBA or merchant-fulfilled cost for the order. Referral fee rate % Amazon states referral fees vary by category. 15% is a common default. Per-item selling fee Useful for Individual plan modeling; set to 0 for Professional plan order math.

Three Amazon order scenarios.

Formula

What the Amazon model includes

Total Amazon fees = Referral fee + Per-item selling plan fees

Amazon says referral fees vary by category and are charged as a percentage of the total sales price, subject to minimums by category. Individual plan sellers also pay a per-item fee. This calculator keeps both values adjustable so the order math can match the category and selling plan you actually use.

Where the model helps

Comparing Individual and Professional plan order economics.
Seeing whether a category-level referral rate changes the product case.
Testing whether fulfilment is the bigger issue than Amazon's fee take.

Useful next step

Once the Amazon stack is clear, use payout margin and break-even ROAS to see how much of the order still remains for traffic and retained profit.
