SellWhere.app's answer
SellWhere.app's answer
SellWhere is the only free tool that lets you enter a sale price once and instantly compare your net payout across 6 major resale platforms — eBay, Poshmark, Mercari, Vinted, Depop, and Etsy. Most fee calculators only handle one platform at a time.
Our eBay calculator goes deeper than any competitor, modeling 20+ item categories, 6 store subscription tiers, and 3 seller levels. Every calculator shows when fees were last verified, with direct links to official fee pages so you can trust the numbers.
SellWhere.app's answer
SellWhere serves two main groups:
SellWhere.app's answer
SellWhere was born from a real frustration: resale platform fees are confusing, constantly changing, and scattered across different help pages. We wanted one place to see exactly what you'd take home on every major platform, with no guesswork.
Resale fees are also in a period of rapid change — Mercari dropped its seller fee to 0% in 2024, Depop eliminated buyer fees in mid-2024, and Vinted launched in the US in January 2026. Keeping up is hard. SellWhere was built to be the single source of truth for resellers navigating these shifts.
