ProfitProof AI — FBA Fee, Margin & Product Research

Score a listing before you buy stock: real fee data, unit economics, break-even and a research checklist. Not financial advice.

Know what a product actually earns before you spend a rupee on stock. ProfitProof AI reads the listing you are looking at, works out the real unit economics, and tells you plainly whether the numbers survive marketplace fees. WHAT IT DOES Reads the product page you are on. One click pulls in the price, weight, package dimensions, category, sales rank and review count. It works out the size tier from the dimensions, because that one setting moves the fulfilment fee more than anything else. Pulls exact fees from Amazon's own calculator. Estimates are a starting point. When you need certainty, one button opens the public FBA Revenue Calculator for that ASIN, and the extension reads the referral fee, fulfilment cost and storage cost straight from it. Your figures then match Seller Central to the cent, in any store. Shows where every unit of revenue goes. A single bar splits your cost, the marketplace fees and what is left. Below it: profit per unit, return on cost, net margin, and the break-even sale price. Gives a verdict, not just numbers. A 0 to 100 score with a plain ruling — worth sourcing, workable, marginal, or walk away — plus a breakdown of which factor moved it. A listing that loses money scores zero. It will not flatter a bad product. Builds your research checklist. Filters for Helium 10 Black Box and Jungle Scout, Keepa checks, financial guardrails and policy notes, all derived from your own thresholds. Switch on checklist mode and tick them off as you verify. Compare and keep. Hold three scenarios side by side. Keep a history of what you have scored. Export to CSV, JSON or PDF, or copy everything to the clipboard. FEE DATA, LABELLED HONESTLY Every marketplace shows where its numbers come from: United States: published 2026 rate card UK and the euro stores: December 2025 European schedule, incl. UK DST United Arab Emirates : the Amazon.ae card, with its AED 50 referral tiers Saudi Arabia: carried over from the UAE card India: the 16 March 2026 schedule, including zero referral under Rs 1,000, closing fees and GST on fees All other stores: a scaled estimate, clearly marked as such For any store not on that list, read Amazon's calculator once and the figures become exact. PRIVACY Nothing leaves your device. No account, no sign-in, no tracking, no analytics, no ads, no remote code. The extension reads a page only when you press the button, only in the tab you are already looking at, using Chrome's activeTab permission. It has no standing access to any website and cannot read anything in the background. LANGUAGES English and Urdu, with a proper right-to-left layout. WHAT IT WILL NOT DO Your buy cost is yours to enter. Amazon never publishes what you pay a supplier, so until you set it, the score is shown as an assumption rather than a result. Category referral rates are top level. Amazon charges at sub-category level, so read its calculator whenever the money matters. Fee schedules change at least once a year. The extension shows when its data was last reviewed and warns you when that becomes stale. This is idea-level guidance for your own research. It is not financial advice, and it does not predict sales. Made by Linkin Solution LLC.
