How Reseller Fees Actually Work
Every reselling platform takes a cut of your sale, but the way they calculate that cut varies wildly. Understanding fee structures is the single most important thing you can do to protect your margins, because a few percentage points can mean the difference between a profitable flip and a loss.
eBay uses a category-based final value fee system. Most categories charge 13.6%, but electronics drop to 9%, authenticated sneakers over $150 are just 8%, and niche categories like musical instruments sit at 6.7%. On top of the percentage, eBay adds a flat per-order fee of $0.30 for sales $10 and under, or $0.40 for sales above $10. If you run promoted listings or sell internationally, those costs stack on top. This is why many sellers are surprised when their actual payout is lower than expected — they forgot to account for the extras.
Mercari keeps it simple with a flat 10% selling fee across all categories. No per-order surcharges, no tiered rates. This predictability makes it easy to calculate profit in your head, which is one reason Mercari is popular with casual resellers.
Poshmark takes a flat 20% commission on sales over $15 and $2.95 on anything $15 and under. That 20% is one of the highest rates in reselling, but Poshmark handles shipping logistics and provides a prepaid label, which simplifies the process. For higher-priced items, that commission cuts deep — a $100 sale loses $20 right off the top.
StockX layers a seller-level fee (7% to 9% depending on your transaction history) on top of a 3% payment processing fee. Reaching Level 4 saves meaningful money at scale, so high-volume sneaker and streetwear resellers are rewarded for staying on the platform.
Depop, Grailed, Vinted, and Facebook Marketplace each have their own structures. Depop recently dropped its selling fee to 0% for US sellers, only charging payment processing. Grailed takes a 9% commission plus processing. Vinted charges nothing to the seller at all — buyers cover platform costs. Facebook Marketplace charges a straightforward 5% or $0.40 minimum.
The bottom line: never assume every platform takes the same cut. Use a reseller fee calculator before listing to know your true profit, and choose the platform that maximizes your margin for each item. That is exactly what tools like Waletix are built to help you do — automatically, on every flip.

eBay charges different final value fee percentages depending on the item category to reflect market dynamics. High-volume categories like electronics (9%) or sneakers with authentication ($150+, 8%) have lower rates to attract sellers, while categories like books and media carry a higher 15.3% rate. This means the category you list under directly impacts your bottom line.
