Current Mercari assumptions

Mercari's current U.S. structure took effect January 6, 2025 for new and updated listings.

  • The selling fee is 10% of item price plus buyer-paid shipping.
  • No separate payment processing fee is modeled.
  • Buyer-paid tax is excluded from the seller fee base.
  • For planning, monetary inputs and the selling fee are rounded to cents before payout and profit; the actual statement controls rounding.
