Walmart vs Amazon
for eCommerce Sellers
Amazon's fees keep climbing. Walmart's marketplace is growing fast with lower costs and less competition. Here's a side-by-side breakdown of what you actually pay on each platform in 2026.
The Complete Fee Comparison
Amazon's headline referral fees look similar to Walmart's — but hidden fees, monthly subscriptions, and aggressive storage charges tell a different story.
| Factor | Walmart Marketplace | Amazon (FBA) |
|---|---|---|
| Monthly Subscription | $0 | $39.99/month |
| Referral / Commission Fee | 6-15% | 8-15% |
| Base Fulfillment Fee | WFS: $3.45+/unit | FBA: $3.22+/unit |
| Inbound Placement Fee | $0 | $0.21-$0.68/unit |
| Storage (Jan-Sep) | $0.75/cu ft | $0.78/cu ft |
| Storage (Oct-Dec) | $0.75/cu ft | $2.40/cu ft |
| Aged Inventory Surcharge | None | $0.50-$6.90/cu ft (after 181 days) |
| Low-Inventory-Level Fee | None | $0.32-$0.47/unit |
| Return Processing Fee | Free for most | $2.12-$5.00+ per return |
| Advertising Cost (Avg CPC) | $0.30-$0.75 | $1.20-$2.50 |
| Competition Level | 150K sellers (growing) | 2M+ sellers (saturated) |
| New Seller Incentives | Up to $75K in savings | Limited (Brand Registry) |
| Organic Visibility | Achievable in weeks | Requires months + ad spend |
Amazon's Hidden Fees Add Up Fast
The Amazon Fee Creep Problem
Amazon's base fulfillment fee starts lower than WFS — but that's before inbound placement fees ($0.21-$0.68/unit), peak storage surcharges (3x normal rates Oct-Dec), aged inventory penalties, and low-inventory-level fees introduced in 2024.
For a typical standard-size product, Amazon's real fulfillment cost is $5.50-$7.50/unit when you factor in all surcharges. WFS runs $3.45-$5.50/unit with no hidden extras.
Competition: 150K vs 2 Million
Amazon has 2M+ active sellers fighting for the Buy Box. Walmart has 150K — and growing. This means dramatically less competition per listing, lower advertising costs, and faster organic ranking.
Walmart Connect ads average $0.30-$0.75 CPC vs Amazon's $1.20-$2.50. That's 50-70% less per click, which translates directly to higher ROAS and more margin.
Amazon's Fee Trajectory Is Not Your Friend
Amazon has raised seller fees every year for the past 5 years. In 2024 alone, they added inbound placement fees and low-inventory-level fees. Walmart's fee structure has remained stable and predictable, with incentives increasing for new sellers.
Smart sellers are diversifying to Walmart now — before the marketplace gets as crowded as Amazon.
