Mercari Fee Calculator
Mercari's selling fee is a flat 10%, plus payment processing. Unlike Poshmark, the buyer often pays shipping separately, which keeps it out of the fee base.
All amounts in USD. One unit = one order.
| Where the money goes | Amount |
|---|
Break-even price: $16.65 — below this you lose money on every sale.
Work backwards from the profit you want.
This accounts for the item price, shipping charged, every active fee, your item cost, shipping cost and monthly fixed costs spread over the units above.
On the example above, Mercari takes 14.6% of every sale. That is the number to compare, not the headline percentage — the fixed fees and the shipping-inclusive fee base are what make the effective rate diverge from the advertised one.
The full fee schedule
Every charge Mercari applies to a United States order, and when each one bites.
| Fee | Amount | When it applies |
|---|---|---|
| Selling fee | 10.0% | 10% of the item price. |
| Payment processing | 2.9% + $0.50 | 2.9% + $0.50 per transaction. |
How the maths works
The calculator does exactly three things: it builds the fee base, applies every active fee, then subtracts your costs. No hidden steps.
Optional fees such as promotions are excluded from those percentages until you switch them on, because they only apply to a share of orders. When enabled, they simply add to the rate.
What this calculator leaves out
- Buyer-paid shipping is excluded from revenue by default.
- Promoted listings spend is not modelled.
Common questions
Is the fee charged on shipping?
The 10% selling fee applies to the item price. If the buyer pays shipping through Mercari's label, that amount is not your revenue and the fee is not charged on it.
Why does the fixed $0.50 matter so much?
On a $10 item, 2.9% + $0.50 is about 7.9% in payment fees alone. Combined with the 10% selling fee and the item cost, low-priced items often lose money — the break-even price line in the calculator shows exactly where that happens.
Are promoted listings worth it?
Promoted listings are charged per click, separately from the sale. If you use them, add the average spend per sale to the item cost. A promotion that lifts a $5-profit item by 10% rarely pays for itself.

If the number above is worse than you expected, the fix is usually one of two things: raise the price, or move the shipping into the item price. Our reverse pricing calculator tells you the price that hits your target; the fee base guide explains why shipping is charged twice.
