Chrome Extension · Free
See StockX Prices, Fees, and Net Profit While You Shop Retail
Profits overlays live StockX market data directly on retail sneaker pages. Buyer Mode, Seller Mode, and Advanced analytics — no tab switching, no manual math.
Three modes, one popup
Buyer Mode
See the lowest StockX asking price per size with total all-in cost — buyer premium, payment processing, shipping, and state tax included. Color-coded against retail so you instantly know if you are paying above or below secondary market.
Seller Mode
See the highest StockX bid per size with your estimated net profit after transaction fee, payment processing, and seller shipping. Know your margin before you add to cart.
Advanced View
1-year sales price chart, per-size listing depth, last sale history, and aggregate ask/bid counts. Understand the full market picture before committing to a purchase.

Common questions
What does the Profits Chrome extension do?
Profits overlays live StockX market data on supported sneaker retailer websites. Buyer Mode shows the all-in StockX asking price per size including all fees. Seller Mode shows the highest bid and your estimated net profit after StockX transaction fee, payment processing, and shipping. Advanced View adds a 1-year price chart, per-size listing depth, and last sale history.
Is Profits free to use?
Yes. Profits is a free Chrome extension. No subscription, no account required, no feature limits. Install it from the Chrome Web Store and it activates automatically on supported retailer pages.
Which sneaker retailers does Profits work on?
Profits integrates with supported sneaker retailer websites and displays StockX data inline. It also includes a manual SKU lookup for any shoe not currently on a supported page.
How does Seller Mode calculate net profit?
Seller Mode fetches the current highest StockX bid for each available size, then subtracts the estimated StockX transaction fee (based on typical seller tier rates), payment processing fee, and seller shipping cost. The result is your approximate net payout. Always verify current fee rates in your StockX seller dashboard as tiers vary by 12-month sales history.
Who makes the Profits extension?
Profits is made by Payback, the same team behind the Payback bill splitting app. The extension is available on the Chrome Web Store.
Does Profits work on non-sneaker products?
Profits is specifically built for sneaker market analytics using StockX data. It is designed for sneaker buyers and resellers evaluating retail prices against secondary market values.
