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.
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; for exact WFS fees with dimensions, use the WFS fee calculator.
Skip the typing. Margenos does this for you on every Walmart listing and every barcode you scan, with real stock counts and the Buy Box.

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.
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.
A Walmart fee calculator that only applies the referral fee will make almost every deal look better than it is. A complete Walmart seller profit calculator takes all of these into account:
Walmart has a WFS cost estimator on its WFS pricing page. It estimates fulfillment and storage from weight and dimensions, but it doesn't include the referral fee, your cost or your profit. It answers "what will WFS charge?" A Walmart marketplace fee calculator like the one above answers "what will I keep?" For the full WFS rate chart, see Walmart WFS fees.
A toy sells for $24.97 in Toys & Games. It ships at 2 lb through WFS and sits in storage for about a month in spring. You pay $10.00 for it plus $0.50 prep.
| Line | Amount |
|---|---|
| Sale price | $24.97 |
| Referral fee (15%) | −$3.75 |
| WFS fulfillment (2 lb) | −$4.95 |
| Storage (0.11 cu ft, 1 month) | −$0.08 |
| Payout before your costs | $16.19 |
| Your cost plus prep | −$10.50 |
| Profit | $5.69 (54% ROI) |
Two more numbers matter when you're standing at the shelf:
If you sell more than one unit, storage and prep scale with quantity, and slow sellers pay storage for longer. Margenos works this out with your quantity, prep cost and WFS storage months, and fills in the price, category and weight from the listing. Learn the full method in how to calculate Walmart profit.
Typing numbers into a calculator works for one item. On a sourcing run you want it automatic: scan a barcode with the Margenos scanner app or open a listing with the Walmart profit calculator extension, type your cost, and see profit, ROI, breakeven and max buy cost, next to the sales estimate and every competing seller. On the top plan, CartIQ adds up the profit on a whole cart. Doing Walmart arbitrage? This is the number that decides buy or pass.

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.
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.
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.
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.
Walmart has a WFS cost estimator for fulfillment and storage fees. It doesn't include referral fees, your cost or profit, so you need a full profit calculator for that.
It's the most you can pay for an item and still reach your target ROI after Walmart's referral fee, WFS fees and your prep cost. If the shelf price is above it, pass.
It's the cost at which you make exactly zero after all Walmart fees and your prep and storage costs. Pay more than that and you lose money on each sale.
Yes. Walmart calculates the referral fee on the total sales price, which includes the item price plus any shipping and handling you charge.
