About Margenos: Walmart Seller Tool & Profit Calculator
Margenos is the Walmart seller tool for resellers who want to know if a product is worth buying before they buy it. Open any Walmart.com product page and Margenos shows your profit after every Walmart fee, who else is selling, how much stock they have, and how fast the item sells.
Built for Walmart Marketplace sellers doing online arbitrage, retail arbitrage and wholesale, it replaces a spreadsheet, a fee calculator and a sales estimator with one panel.
WALMART PROFIT CALCULATOR
- Walmart referral fees by category, calculated for you
- WFS fees (Walmart Fulfillment Services) by shipping weight, plus storage fees, or your own seller-fulfilled shipping cost
- Profit, ROI, margin and breakeven price as you type your cost
- Max cost: the most you can pay and still hit your target profit
SELLERS, STOCK AND THE BUY BOX
- Every competing seller on the listing, with fulfillment type (Walmart, WFS or seller-fulfilled)
- Stock per seller, and a running total when you hover
- Who holds the buy box, with links to each seller's storefront
SALES ESTIMATES AND PRICE HISTORY
- Walmart sales estimates shown with a range and their source. When there isn't enough data, Margenos says so instead of guessing.
- Buy box price and Walmart price history
- Offer count, review and rating history
VARIATIONS
- Every size, pack count or color on the listing, with its price and stock
ONE ACCOUNT FOR CHROME AND YOUR PHONE
- Use the same login as the Margenos barcode scanner app for iPhone and Android: scan in the store, research at your desk
- One scan allowance shared between the app and the extension
- Plan, billing and settings in the panel's Settings tab
- Margenos Help: 24/7 support chat in the Settings tab that can check your plan, reset your password, open billing, work out fees, or pass you to a person
READS ONLY WHAT YOU OPEN
Margenos reads only the Walmart pages you open yourself. It never clicks, browses, or adds anything to a cart.
Every plan starts with a 14-day free trial. Plans and pricing: https://margenos.com/#pricing
