Marketplace Fee Comparison: Amazon vs TikTok vs Walmart vs Shopify
Quick Definition
A marketplace fee comparison tool shows your per-unit profit across Amazon FBA, TikTok Shop, Walmart, Shopify, eBay, and Etsy side-by-side — helping multi-channel sellers find the most profitable platform.
Why Platform Choice Matters
The same $30 product can yield $12 profit on TikTok Shop, $8 on Amazon FBA, $10 on Walmart, and $14 on Shopify — or the reverse, depending on your cost structure. Platform fees range from 6% (TikTok referral) to 20% (Amazon referral + FBA fulfillment). With 78% of e-commerce sellers now selling on multiple channels, understanding fee differences is critical to margin optimization.
Fee Structures Compared
Amazon FBA: 15% referral + $3-$6 fulfillment + $0.87/cu ft storage + $39.99/month. TikTok Shop: 6-8% referral + 1.5% transaction + $2.90-$5.40 FBT. Walmart WFS: 12% referral + $3.45-$5.75 fulfillment, no monthly fee. Shopify: $39/month + 2.9% + $0.30 payment processing, no referral fee. eBay: 13.2% final value + 2.9% + $0.30 payment. Etsy: 6.5% transaction + 3% + $0.25 payment + $0.20 listing fee.
Existing Comparison Tools
CalcBee offers a limited multi-platform calculator. Helium 10 published a comparison article but no interactive tool. Most sellers use 3-4 separate calculators and a spreadsheet — Amazon's Revenue Calculator, a TikTok fee calculator, and Shopify's margin calculator. There is no single free tool that compares all major platforms with the same inputs.
