Fee Notes
How Mercari fees apply
Mercari's fees page says that effective January 6, 2025, a 10% selling fee applies to the combined amount of the item price and buyer-paid shipping for new and updated listings. That is why this calculator includes buyer-paid shipping in the fee base instead of treating it as a neutral pass-through.
Mercari's fee-structure FAQ repeats the same seller-side rule and says sellers pay a flat 10% selling fee on the completed item price and buyer-paid shipping under the new structure. This page is intentionally limited to that current seller-side baseline rather than older pre-update listing behavior.
Mercari also says no separate payment processing fee applies to new or updated listings after January 6, 2025. This calculator therefore shows only the 10% selling fee. Cash-out charges such as Instant Pay and direct deposit exceptions are not selling fees and are not included in the order-level estimate.
