Formula and calculation logic

Referral fee = selling price × referral fee rate

Profit per unit = selling price − referral fee − FBA fee − other fees − product cost − inbound shipping − ads

Break-even price = (fixed per-unit costs) ÷ (1 − referral fee rate)

Estimate per-unit Amazon FBA profit after referral, fulfilment, product, inbound shipping, and advertising costs.

Selling price is reduced by the referral percentage, fulfilment and other per-unit fees, product cost, inbound shipping, and advertising spend.

Assumptions

  • Fees vary by marketplace, category, item size, and date. Use current Seller Central figures. Use one currency for every amount. Taxes, returns, unsold inventory, and storage unless allocated in other costs are excluded.
