Amazon takes 15% referral plus FBA fees. eBay charges 13% final value fees. Etsy layers listing, transaction, and payment fees. Shopify charges mainly payment processing. Walmart and TikTok Shop have their own structures.

Whether you are a beginner or experienced professional, this free online tool provides instant, reliable results without manual computation. By automating the calculation, you save time and reduce the risk of costly errors in your planning and decision-making process.

Why Use This Multi-Channel Fee Comparison Calculator?

Different products are profitable on different channels. A product that barely breaks even on Amazon might thrive on Etsy or your Shopify store. This calculator eliminates guesswork by showing exact profit across 7 channels simultaneously. One calculation, seven answers. Having a precise figure at your fingertips empowers better planning and more confident decisions.

How to Use This Calculator

  1. Enter your product selling price.
  2. Enter the cost of goods (COGS) per unit.
  3. Enter the shipping cost to customer (if relevant).
  4. The calculator applies each channel's fee structure automatically.
  5. Compare net profit and margin across all 7 channels.
  6. Choose the most profitable channel(s) for your product.

Formula

For each channel: Fees = Channel-specific fee calculation Net Profit = Selling Price − COGS − Shipping − Channel Fees Margin = Net Profit / Selling Price × 100 Channel fee structures applied automatically based on current published rates.

Example Calculation

Result: Best: Shopify ($15.75) > TikTok ($13.70) > Walmart ($13.10) > eBay ($12.65) > Amazon FBM ($12.50) > Etsy ($12.12) > Amazon FBA ($8.60)

At a $35 selling price with $10 COGS and $5 shipping, Shopify nets the most ($15.75) because fees are only payment processing. Amazon FBA nets the least ($8.60) because of referral + fulfillment fees. However, Amazon FBA provides the most traffic and convenience, which may justify lower per-unit profit.

Tips & Best Practices

Channel Fee Summary (2024–2025)

Amazon FBA: 15% referral + $3–8 FBA fee per unit. Amazon FBM: 15% referral (no FBA fee). eBay: 13.25% final value fee (includes payment). Etsy: $0.20 listing + 6.5% transaction + 3% + $0.25 payment. Shopify: $39/month + 2.9% + $0.30 payment. Walmart: 6–15% referral (category dependent). TikTok Shop: 2–8% commission + payment fees.

Choosing Your Primary Channel

Your primary channel should have: (1) Highest absolute profit per month (volume × margin), (2) Strong product-market fit for your category, (3) Manageable competition level, (4) Alignment with your brand positioning. Don't choose based solely on lowest fees — traffic and conversion rate matter more.

Multi-Channel Inventory Management

Selling on multiple channels requires synchronized inventory to avoid overselling. Solutions range from spreadsheets (1–2 channels, <100 SKUs) to dedicated software (ChannelAdvisor, Sellbrite, Linnworks) for 3+ channels. Amazon MCF (Multi-Channel Fulfillment) can fulfill orders from other channels using your FBA inventory.

Frequently Asked Questions

Which marketplace has the lowest fees?

Your own website (Shopify/WooCommerce) has the lowest fees at ~3% payment processing only. Among marketplaces, TikTok Shop (2–8% + payment) and Walmart (6–15%) currently have the lowest fees. Amazon (15% + FBA) and Etsy (10‒12% total) have the highest combined fees.

Should I sell on Amazon or Shopify?

Both, ideally. Amazon provides massive built-in traffic (300M+ active customers) but higher fees. Shopify lets you build a brand with lower fees but costs more to acquire customers. Use Amazon for discovery and volume; use Shopify for brand building and higher margins on repeat customers.

Is eBay still worth selling on?

Yes, for certain categories. eBay has 130M+ active buyers and strong demand for electronics, collectibles, auto parts, refurbished goods, and fashion. Final value fees (13%) are competitive. eBay's managed payments simplified the process. It's often overlooked but can be highly profitable.

What about Walmart Marketplace?

Walmart Marketplace has lower referral fees (6–15% vs. Amazon's 8–15%) and no subscription fee. However, traffic is lower and the application process is selective. Products that do well on Walmart: everyday essentials, family products, and value-oriented items. It's growing rapidly.

Is TikTok Shop worth it?

TikTok Shop is growing explosively with low fees (2–8% commission currently). It's best for viral, visual, impulse-buy products that can be demonstrated in short videos. The platform skews young (18–34). If your product lends itself to video demos, TikTok Shop can be very profitable.

How many channels should I sell on?

Start with 1–2 channels, master them, then expand. Most successful sellers operate on 3–5 channels. Each additional channel increases revenue but also complexity in inventory management, customer service, and listing optimization. Use multi-channel management tools (ChannelAdvisor, Sellbrite) at 3+ channels.
