Mercari Fee Calculator Community

What this tool does

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.

How to use it, step by step

1. Enter your sale price.
2. Optionally enter a shipping cost you paid yourself.
3. See Mercari's real selling fee, processing fee and your exact net payout instantly.

Tips from the guide

• 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.

Who uses it

• Mercari sellers pricing items. See real take-home before listing.
• Resellers comparing Mercari to Poshmark or eBay. Get a real, comparable net-payout figure across platforms.
• Anyone unsure why their payout was lower than the sale price. See exactly which two real fees explain the gap.

How to ask a question people can answer

A good thread on the Mercari Fee Calculator saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.

• Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
• Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
• Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
• One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
• Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
