Mercari Fee Calculator
Mercari charges two real, published fees on every sale: a 10% selling fee on the sale price, and a separate payment processing fee of 2.9% + $0.30 per transaction. Enter your sale price and this tool auto-computes both real fees and sums them into your exact net payout, instead of you having to remember or look up either rate.
If you paid for your own shipping label outside Mercari's prepaid label system, add that cost too, and the tool subtracts it from your payout for a fully real, all-in net figure.

Tips for the best results
- Mercari's 10% selling fee and 2.9% + $0.30 processing fee are both charged on every standard sale — there's no threshold or category variation like some other marketplaces.
- If Mercari provided a prepaid shipping label, its cost is typically deducted separately from the label price you chose, not from this seller-fee calculation.
- Local/in-person Mercari sales have a different, lower fee structure than shipped sales — this tool models the standard shipped-sale fees.
Common mistakes to avoid
- Forgetting the payment processing fee is separate from and in addition to the 10% selling fee, not included in it.
- Assuming Mercari's fee is negotiable or tiered by price — it's a flat 10% + processing on standard sales.
- Not subtracting your own label cost if you opted out of Mercari's prepaid label.
