I want to open Etsy shop but analyze: can I actually profit on Etsy? Map Etsy economics: fees (listing, transaction, payment processing, advertising). Calculate: if item sells for $20, after all fees and costs, what's actual profit? Show me the Etsy math: these fees, this cost, this is actual take-home. Give me the profitability assessment: these products work on Etsy, these don't. Include: whether Etsy fees eat all profit, what products have good margins, and if Etsy is viable or just breaking even.
