A margin audit for a single Etsy listing. Open any public listing and the calculator lays out every deduction between the price a buyer pays and the money the seller keeps, line by line: listing fee, payment processing, transaction fee, offsite ads, VAT on fees, and the rest. The line no generic tool computes: Etsy takes a 15% transaction fee on the prepaid US import tariff inside a DDP price, and that single charge can push a thin listing below zero. Sellers who ship from outside the United States have been paying this fee invisibly; here it is counted up front, before the price is set. The tool answers one question precisely: after every deduction, what does this listing actually pay the seller? All math runs locally in your browser, the extension makes zero network requests, and nothing about your shop leaves the device. Use it as a free web calculator for quick checks while you plan a price, or install the Chrome extension to see the breakdown directly on the listing page while you browse Etsy, including competitor listings you are benchmarking against. Practical uses: setting an introductory price for a new product, checking whether a sale discount still leaves margin, comparing what a price change does to the payout, and auditing old listings whose fees were never recalculated. It is built for Etsy sellers who ship internationally and price for margin rather than for guesses, and for anyone doing market research on Etsy pricing who wants the real number instead of a rounded estimate. A Pro tier with an all-shop profit view, tariff simulation by destination country, and margin-drop alerts is on a waitlist; billing is not live, the tool is free today. The maker is Vlad Kovnerov, who builds seller tools and publishes the underlying math openly on the project page.
