Walmart Marketplace fees in 2026 — the full breakdown
Walmart charges a referral fee on every sale and a separate WFS stack if you use its fulfillment. The table below is the 2026 picture; each line has a calculator that nets it against your numbers.

What the numbers mean for a seller
The referral tier is decided by your contract category, not your product's price. WFS fulfillment is dimensional-weight driven, so a light but bulky item can cost more than a heavy compact one. Storage is the slow killer — it is cheap for 90 days and expensive past 365, which is why the fee calculator folds months-in-storage into the per-unit net.
Where each number gets calculated
- Fee calculator — net per unit after referral, WFS or self fulfillment, storage and returns
- FBA vs WFS — same SKU through Amazon and Walmart, incl. fuel and peak surcharges
- WFS claims — what lost and damaged inventory should reimburse
What Walmart sellers need to track
Free calculators that surface each real cost of selling on Walmart before it eats your margin.
True per-unit cost
Walmart charges a referral fee (most categories 15%) with no monthly subscription, and WFS adds fulfillment + storage. Get your real net per unit and see whether WFS or self-fulfillment keeps more.
FBA vs WFS
Fast movers are nearly tied; slow movers and seasonal inventory are structurally cheaper on WFS. Run the same SKU through both channels and find your crossover.
Lost inventory, listing errors & 2D barcodes
WFS loses or damages units and sellers under-claim. Work out the exact claim amount, fix the GTIN check digit before Walmart rejects your listing, and build a GS1 Digital Link QR for Sunrise 2027.
