The true cost of selling on Mercari in 2026
Every fee below comes from one verified data source (last checked 2026-10). Pay attention to the "charged on" column — most fees apply to the whole order, not just your item price.
| Fee | Percentage | Fixed | Charged on |
|---|---|---|---|
| Selling fee | 10% | — | Item + buyer-paid shipping |
| Payment processing | None | — | Removed Jan 2025 |
Shipping you charge the buyer is part of the fee base on most platforms. That means "cheap shipping, higher item price" and "higher shipping, cheaper item" cost you exactly the same in fees — the only way to lower fees is to lower the order total or move sales to cheaper channels.
The Mercari price formula
Price = (target profit + costs) ÷ 0.90 − buyer-paid shipping. With a $20 target, $14.50 in costs and $6 buyer-paid shipping you need $32.33.
Because the fee also applies to buyer-paid shipping, cheaper shipping options raise your take-home slightly.

How to protect your profit margins on Mercari
- Leave room for Mercari's smart pricing and offers.
- Round up to the nearest dollar.
- Count packaging, labels, tape and inserts in your costs — at $0.50–$1.50 per order they're often the forgotten 3% of margin.
- Use reverse mode before you list: decide the profit you want, then price to it, rather than discovering your margin after the sale.
Frequently asked questions
Does Mercari charge fees on customer shipping?
Mercari calculates its selling fee on the item price; payment processing (where charged) applies to the order total.
What is the minimum selling price to avoid losing money (break-even)?
The break-even threshold is the exact price at which revenue covers product cost, packaging, shipping, ad spend and all platform percentage and flat fees. FeeOrbit computes it live in the results card.
How does the reverse pricing calculator work?
Reverse mode lets you set the net profit you want (for example $20). The engine solves for the list price needed after deducting every percentage and flat fee: price = (profit + costs + flat fees) ÷ (1 − percentage fees) − shipping charged.
