About Feescout

Feescout is a free suite of fee calculators built for marketplace sellers who want to know their true profit before they list. Whether you're selling on eBay, Etsy, Amazon FBA, Poshmark, Mercari, or any other platform — Feescout shows you every fee, your net profit, and which platform is best for each item.

Who Built This?

Hi, I'm Kristóf Vizy — a developer and reseller. I built Feescout because I was tired of guessing how much I'd actually make on each sale after all the platform fees, shipping costs, and payment processing charges.

What Makes Feescout Different

• Truly free. Every calculator works without an account. No credit card, no trial.
• 12 platforms. eBay, Etsy, Amazon FBA, Poshmark, Mercari, Depop, TikTok Shop, Whatnot, Grailed, StockX, PayPal, and Stripe.
• Cross-platform comparison. See the same item's profit on every marketplace, side by side.
• Accurate fees. Verified against official platform documentation, updated regularly.
• Instant results. All calculations happen live as you type.

The Mission

Marketplace fees are confusing and opaque. A $50 sale can net you anywhere from $33 to $48 depending on where you sell. Feescout exists to make fee transparency free and accessible for every seller.
