What Are Marketplace Seller Fees?
Marketplace seller fees are the charges online platforms deduct from a seller's revenue for listing, selling, and processing payments. Common types are listing fees, referral or transaction fees (a percentage of the sale price), payment processing fees, and optional advertising or fulfillment fees. Fee structures vary by platform and change over time.
How Fees Affect Profit
Net proceeds = sale price − all platform fees − product cost − shipping. Because many fees are percentages of the sale price, they grow as prices rise.
Why They Matter for Pricing
Sellers often include expected platform fees when setting prices so that the margin after fees matches their target.
