How Mercari fees affect your earnings

Mercari's fee structure has two main components — both reduce what lands in your account.

Fee Type Rate Who Pays
Selling fee 10% of sale price Seller
Payment processing fee 2.9% + $0.50 Seller (deducted from payout)
Shipping (Mercari label) Varies by weight Buyer or seller
Example: $40 sale (seller shipping) ~$5.66 total fees ~$34.34 to seller

Mercari's selling fee (10%) and payment processing fee (2.9% + $0.50) are both deducted from your payout before you receive funds. On a $40 sale, that's roughly $4.00 + $1.66 = $5.66 in fees before shipping costs. Always verify current rates at mercari.com — fee structures change.

In Upcyclist, enter the actual fees Mercari charged when you mark an item sold. That way your profit reflects what you really received — not an approximation based on the sticker price.
