About FeeMath
See every fee Etsy and 10 other marketplaces charge, and your real profit
FeeMath is a set of free fee and profit calculators for online sellers. Enter your price, shipping and costs to see every fee and what you actually keep on Etsy, eBay, Amazon, Walmart, Poshmark, Mercari, Depop, Whatnot, Shopify, TikTok Shop and Facebook Marketplace. A compare page shows all 11 platforms side by side. FeeMath Pro is an Etsy profit analyzer: upload your Etsy monthly statement CSV and get every fee by type (transaction, processing, listing, Offsite Ads, Etsy Ads, shipping labels), your real fee rate, and profit per order and per item. The file is read in your browser and never uploaded. Calculators are free with no signup. Pro is free for the first 25 orders, then $9/month. Available in English, Spanish and Arabic.
