Real Profit: Your real Etsy margin after ALL fees. No subscription

Etsy fees take 12 to 20 percent of every sale and most sellers find out in the monthly statement, after they have priced everything wrong. Real Profit shows your true net margin directly on the listing page and in Shop Manager: the 6.5 percent transaction fee charged on price plus shipping, 3 percent plus 25 cents processing, the listing fee, an Offsite Ads simulation capped at 100 dollars per order the way Etsy actually applies it, and your own production cost with Printify and Printful presets built in. Two implementation details that mattered. The content script only runs on etsy.com and everything is computed locally, nothing is uploaded. Fee rates come from a remote config, because Etsy changes its fee schedule and a hardcoded rate would quietly make every number wrong. The pricing is the point: the complaint I hear most from sellers is subscriptions quietly eating the margin the tool was supposed to protect. Free for one listing at a time, one time payment for the bulk shop audit and CSV export. Tell me what fee or edge case I am still missing. I want the number on screen to be what you actually keep.
