Walmart profit calculator

See Walmart referral fees, WFS fulfillment and storage, and your real profit and ROI before you buy inventory. Built on the same fee engine as the Margenos app.

Your numbers

Referral fees follow Walmart's published category rates; WFS fees use Walmart's weight tiers, including the under-$10 and apparel surcharges. Rates checked September 20, 2026. Storage and self-ship costs are estimates. Oversize and hazmat surcharges aren't included.

How Walmart seller fees work

Every sale on Walmart Marketplace pays a referral fee: a percentage of the sale price set by category. Most categories are 15%, some are price-tiered (apparel is 5% under $15, grocery and beauty are 8% under $15 or $10), and a few, like consumer electronics, are 8%.

If Walmart fulfills the order through Walmart Fulfillment Services (WFS), you also pay a fulfillment fee based on shipping weight, plus monthly storage. Items under $10 carry an extra $1.00, and apparel an extra $0.50.

Check every product in one scan

This calculator is the same fee engine Margenos uses. In the app and the Chrome extension it fills itself in: the category, the weight, the current buy box price and every competing seller come from the listing, so you only type your cost.

  • Profit, ROI and max buy cost on every listing
  • Sales estimates with their range and source
  • Every seller and their stock, and who holds the buy box

Questions

How much does Walmart take per sale?

Walmart charges a referral fee on each sale, set by category. Most categories are 15% of the sale price; some are lower or price-tiered, such as apparel at 5% under $15 and consumer electronics at 8%. There is no monthly seller subscription fee.

How are WFS fees calculated?

WFS fulfillment fees are based on the item's shipping weight, which is the unit weight plus packaging, rounded up to the next pound. Items under $10 add $1.00 and apparel adds $0.50. Storage is charged monthly by cubic foot and rises in October through December.

Is this Walmart profit calculator free?

Yes. The calculator on this page is free to use. The Margenos app and Chrome extension fill in the category, weight, price and competing sellers for you from the listing.

What is a good ROI for Walmart arbitrage?

Many resellers aim for at least 30% ROI after all fees, but the right target depends on how fast the product sells and how much competition is on the listing. Margenos shows sales estimates and the competing sellers next to your ROI for that reason.
