Walmart Fulfillment Services (WFS) Fees Explained, With Examples
Walmart Fulfillment Services (WFS) is Walmart's answer to Amazon FBA: you send inventory to Walmart's warehouses, and Walmart picks, packs, ships and handles customer service and returns. The fee structure is simpler than many sellers expect, but a few surcharges and the peak-season storage rule can change your margin. Here is how the fees work, with worked examples.
Fulfillment fees
According to Walmart's WFS fees page (updated May 27, 2026), the standard fulfillment fee is charged per unit by shipping weight:
- 1 lb or less: $3.45
- 2 lb: $4.95
- 3 lb: $5.45
- 4–20 lb: $5.75 plus $0.40 for each lb over 4 lb
Surcharges are added on top:
| Surcharge | Amount per unit |
|---|---|
| Apparel | $0.50 |
| Hazardous materials | $0.50 |
| Item price under $10 | $1.00 |
| Oversize 1 | $3.00 |
| Oversize 2 | $20.00 |
Big and bulky items have a separate schedule, which Walmart lists as $155 plus $0.80 per lb over 90 lb for items up to 500 lb. Check the page for heavier tiers and exact size definitions.
Storage fees
| Period | Fee |
|---|---|
| January–September | $0.75 per cubic foot per month |
| October–December, stored up to 30 days | $0.75 per cubic foot per month |
| October–December, stored more than 30 days | $0.75 + $1.50 per cubic foot per month |
| Stored 366–450 days (from June 30, 2026) | $2.25 per cubic foot per month |
| Stored more than 450 days (from June 30, 2026) | $7.50 per cubic foot per month |

Worked examples
Using the published rates (calculation only; your referral fee and other costs come on top):
- Phone case, 0.5 lb, sells for $14.99: $3.45 fulfillment. No price surcharge because it is above $10.
- T-shirt, 0.8 lb, sells for $9.99: $3.45 + $0.50 apparel + $1.00 under-$10 = $4.95. The under-$10 surcharge alone adds about 10% of the price.
- Kitchen appliance, 7 lb: $5.75 + 3 × $0.40 = $6.95.
- Storage over peak: a carton of 2 cubic feet that sits from October 1 to November 30 pays $0.75 × 2 for October, then ($0.75 + $1.50) × 2 for November, about $6.00 in total for the two months.
Tip: If a product sells for just under $10, test pricing it at $10 or above, or bundle two units. Removing the $1.00 surcharge can matter more than a small price change.
Common WFS fee mistakes
- Using product weight instead of shipping weight. Packaging adds weight and can push an item into the next tier.
- Ignoring the under-$10 surcharge. It applies per unit, so it hits low-price, high-volume items hardest.
- Overstocking for Q4. Units stored more than 30 days in October–December pay three times the base storage rate.
- Forgetting aged stock. From June 30, 2026, units older than 450 days pay $7.50 per cubic foot per month, ten times the January–September rate.
- Comparing only fulfillment fees. Include inbound freight, prep and returns when comparing WFS with other options.
WFS vs your own 3PL
WFS makes sense when Walmart is a meaningful channel, your products are small and standard-size, and you want fast-delivery badges without managing carriers. A third-party warehouse can be better when you sell across many channels, have oversized or slow-moving items, or need custom packaging. Many sellers use both: WFS for best sellers, a 3PL for everything else.
Checklist before you send inventory
- Weigh and measure each SKU in its final packaging and compare against Walmart's size tiers.
- Calculate the total fee per unit, including surcharges, and add it to your margin sheet.
- Price above $10 where possible, or bundle low-price items.
- Send only the stock you expect to sell within the peak window to avoid the October–December over-30-day storage surcharge.
- Review aged inventory monthly and remove or discount units approaching 366 days.
