What You Keep

The flat component is what makes small sales expensive. The same fee schedule costs a very different effective rate depending on the order size:

Sale	Fees	You receive	Effective rate
$5.00	$1.15	$3.86	22.90%
$20.00	$3.08	$16.92	15.40%
$50.00	$6.95	$43.05	13.90%
$100.00	$13.40	$86.60	13.40%
$500.00	$65.00	$435.00	13.00%

Ten Percent Plus Processing

Mercari charges a selling fee on the item price and a payment processing fee on top. Both are deducted before payout, so the number in your app after a sale is already net of them.

Component	Rate
Selling fee	10% of the item price
Payment processing	2.9% + 50¢

Note the 50¢ flat, which is higher than most processors. On a $5 item that is 10% on its own.

Shipping Decides Your Margin

Mercari lets the buyer or the seller pay shipping, and the choice changes both your net and your conversion rate.

Approach	Effect
Buyer pays shipping	Higher net, lower conversion, listing looks cheaper in search
Seller pays (free shipping)	Lower net, better placement and conversion
Build shipping into the price	Same fees, simplest to reason about

Because the selling fee applies to the item price, building $6 of shipping into the price costs 10% of that $6 — a small price for the conversion lift on most items.

The Under-$10 Problem

At low prices the flat components dominate. Between the flat processing fee and real postage, items below roughly $8 are usually not worth listing individually. Bundle them.

Cancellations and Ratings

A cancelled sale returns the fees but not the time, and repeated cancellations affect your rating and search placement. List only what you can find and post.

Charging to Hit a Target Payout

Adding 12.90% to your price under-recovers, because the percentage then applies to the larger amount as well. The correct gross-up divides:

`` charge = (target + flat fees) ÷ (1 − percentage rate) ``

To receive	Charge
$100.00	$115.38
$1,000.00	$1,148.68

Reducing What You Pay

• Raise average order value. The flat fee is fixed, so bundling two $20.00 orders

into one $40.00 order saves the second flat charge outright.

• Watch the optional surcharges. International and currency-conversion fees stack on top

of the base rate and are easy to miss when you price for a domestic market.

• Negotiate at volume. Most processors will discuss custom rates once you are processing

meaningful monthly volume; the published rate is a starting point, not a law.

• Do not migrate for 0.2%. The engineering and support cost of changing platforms

usually exceeds a small rate difference for years.

Shipping is charged separately depending on who buys the label.
