Which Platform Has the Lowest Fees?

Every marketplace charges differently. eBay takes ~14%, Poshmark takes 20%, Depop charges 0% seller commission. The best platform depends on what you're selling, your audience, and your volume. Our calculators show you the exact numbers for your items.

Why Marketplace Fees Matter

Marketplace fees are the hidden cost of reselling. A $50 item can net you anywhere from $33 (on Poshmark) to $48 (on Depop) — a 45% difference in profit — depending on where you sell it. Most sellers don't realize how much they're losing to fees until they actually calculate them.

Our free calculators break down every fee — final value fees, transaction fees, payment processing, listing fees — so you can price your items to actually make money. Use the cross-platform comparison to find the best marketplace for each item you sell.

Whether you're reselling thrifted clothing on Poshmark, flipping electronics on eBay, selling handmade goods on Etsy, or moving sneakers on StockX — knowing your true profit per sale is the foundation of a profitable reselling business.
