Reseller Platform Fees Compared: eBay, Poshmark, Mercari, Depop, StockX

The fee a marketplace charges decides how much of every sale you actually keep, and the platforms differ enough that the same item can net noticeably different amounts depending on where you list it. Knowing the numbers before you price something is the difference between a healthy margin and an accidental loss.

Fees also change. Marketplaces adjust their rates fairly often, and they vary by category and by your seller status, so it's worth confirming the current figure rather than relying on an old rule of thumb. The calculators let you adjust the rate to match what you're actually charged.

eBay charges a final value fee of roughly 13.6% for most standard categories, plus a small per-order fee of about $0.40, applied to the item price and the shipping the buyer pays. The exact percentage depends on the category.

Poshmark keeps things simple: a flat $2.95 on sales under $15, or 20% of the item price at $15 and above, with a prepaid shipping label the buyer covers. Mercari charges a flat 10% selling fee on the item plus buyer-paid shipping, having moved payment processing to a buyer-paid fee.

Depop is the cheapest for US sellers — no selling fee, just a 3.3% plus $0.45 payment-processing charge (a 10% fee still applies in some other countries). StockX is the priciest here, with a transaction fee of around 9% that falls with your seller level, plus a flat 3% payment-processing fee.

The basic formula is the same everywhere: your payout is what the buyer pays minus the platform's fees, and your profit is that payout minus what the item cost you and what you spend on shipping. The wrinkle is what each fee is charged on — item only, or item plus shipping — and whether shipping is your expense or a prepaid label.
