Calculate true profit per order after Amazon FBA fees, referral fees, PPC spend and product cost. Enter your selling price, product cost, FBA fulfilment fee, referral fee percentage, PPC spend and return rate — the calculator outputs profit per order, margin percentage and monthly profit for both Amazon FBA and a UK 3PL alternative.
Amazon FBA charges a referral fee (typically 8–15% of selling price) and a fulfilment fee per unit (based on size and weight, from approximately £2.50 for a large letter to £6.50+ for a 5kg parcel). Selling via a UK 3PL like PackPro on Seller Fulfilled Prime or FBM replaces the FBA fulfilment fee with pick and pack costs and postage — the referral fee stays the same either way.
This calculator is for guidance only. Always verify current FBA fees in Seller Central. See our Amazon FBA vs 3PL savings calculator for a full monthly cost comparison, or contact PackPro for an exact quote.
