How this estimate works
This calculator follows Mercari's fees help article for US sellers on new and updated listings: a 10% selling fee on the item price. There is no separate seller payment processing fee under this structure.
The 10% fee is estimated on the item sale price. Shipping is your cost — it reduces profit and is not added to the fee base.
Buyers pay a separate 3.6% Buyer Protection fee. That fee is not deducted from your payout and is not included here.
This is an independent planning tool, not an official Mercari calculator. Confirm current rates in the Mercari app. Full details are in Mercari's fees help article.
