Sellers

Online seller fee calculators help you figure out what actually lands in your bank account after marketplace cuts, payment processing fees, and the smaller line items that get missed. Coverage spans nine major platforms — eBay, Etsy, Mercari, Poshmark, PayPal, Stripe, Square, Venmo, and Shopify. Fee schedules are pulled from each platform's published policies and updated when they change.

For the layered fee model in plain language — including the hidden costs that ambush new sellers — read the seller fees guide below. The calculators handle category-specific rates, discount tiers, promoted-listing add-ons, and currency conversion spreads where applicable.
