How FBA profitability is estimated

The estimator subtracts referral fees, FBA fulfillment, product cost, inbound prep, storage, ads, and expected returns from sale price.

Usage notes

  • Referral fee = max(sale price × referral fee rate, minimum referral fee).
  • Total per-unit cost = product cost + referral fee + FBA fulfillment + inbound/prep + storage + ads + expected return cost.
  • Net margin = net profit per unit ÷ sale price, ROI = net profit per unit ÷ landed cost.
