Frequently asked questions
It varies widely: Amazon referral fees are typically 8β15%, Etsy around 6.5% plus payment fees, and fashion marketplaces can exceed 20%. Always model the total, not just the headline commission.
Because a return costs you the shipping and the payment fee again while the commission is usually not refunded in full. Even a 4% return rate meaningfully reduces the average payout.
On most marketplaces commission is charged on the total the buyer pays, shipping included. Check your own fee schedule, as this is a common source of margin surprises.
